Product description

The EMC RecoverPoint product family provides a comprehensive data protection solution for enterprise and commercial customers, providing integrated continuous data protection and continuous remote replication to recover applications to any point in time.

RecoverPoint systems enable reliable replication locally with one RPA cluster, and over any distance to up to four remote RPA clusters. RecoverPoint systems support replication of data that applications are writing to SAN-attached storage using existing Fibre Channel (FC) and iSCSI infrastructure to integrate seamlessly with existing host applications and data storage subsystems. For remote replication, the systems use existing connections to send the replicated data over FC and WAN, and uses FC and IP infrastructure to replicate data asynchronously or synchronously. The systems provide failover of operations to another cluster in the event of a disaster at the production cluster.

The RecoverPoint family consists of three licensing offerings:

◆ RecoverPoint/CL for EMC and non-EMC storage platforms.

◆ RecoverPoint/EX for EMC storage platforms (Block), licensed by storage array.

◆ RecoverPoint/SE for VNX series, CLARiiON CX3 and CX4 series, and Celerra unified storage environments.

Note: Throughout this document, in the context of comparing “RecoverPoint” and “RecoverPoint/SE”, the term “RecoverPoint” is synonymous with “RecoverPoint/CL and RecoverPoint/EX”, unless otherwise noted.

Note: An EMC Support Matrix (ESM) on E-Lab™ Navigator https://elabnavigator.EMC.com serves the RecoverPoint product family. After logging in, select the PDFs and Guides tab and look for RecoverPoint in the Information Management Software section.

Product description

Table 2 on page 3 identifies the build and size of the RecoverPoint ISO image associated with the 4.0 release. The build also appears in the Unisphere for RecoverPoint login screen, in response to the get_versions CLI command, and in the Installation Manager (boxmgmt) header.

Notes on performance

Additional performance information will be provided in the RecoverPoint 4.0 Performance Guide, to be available shortly after product release.

Table 3 on page 3 and Table 4 on page 3 present general throughput and IOPS values for Gen4/Gen5 RPAs and for virtual RPAs (vRPAs). You can use these values to develop general sizing requirements for your RecoverPoint system. Note, however, that the following limitations apply:

◆ Values in tables are for non-distributed consistency groups.◆ Throughput rates were measured using a write size of 64 KB.◆ The values include writes only.

Note: Reads do not impact performance.

These values are independent of:

◆ Link type (WAN-IP, FC)◆ Replication mode (async, sync)

Notes: 1. Throughput and IOPS increase linearly with the number of RPAs, provided that the splitter

supports the increased levels of performance.

2. For async replication of distributed consistency groups, RecoverPoint 4.0 supports throughput of up to 400 MB/s, depending on storage array configuration.

Note: Each vRPA CPU operates at speed of 2.13 GHz.

Configuration limits

In addition to being supported on 64-bit RPA hardware platforms, RecoverPoint/SE is now supported on virtual RPA platforms. For deployment, best practices, and limitations, refer to the EMC RecoverPoint vRPA Technical Notes.

RPA clusters consisting of physical RPAs require either a dual fabric or a direct attach network topology.

Table 5 on page 4 lists the 4.0 releases supported across RPA hardware types.

EMC will continue to support existing configurations of RPA hardware platforms running earlier versions of RecoverPoint.

1. When using a mix of RPA hardware types (Gen5 and Gen4), it is highly recommended to configure the latest types as RPA 1 and RPA 2 (cluster control RPAs) to improve system function and performance.

Break fix/support

EMC will handle break/fix activity for Gen4 and Gen5 RPA hardware platforms purchased through Direct Express and Channel Express.

SAN support

Table 6 on page 4 lists Fibre Channel support across RPA hardware types. When using virtual RPAs, iSCSI is supported in 1 Gb/s and 10 Gb/s network infrastructure.

Product description

Scalability

The scalability limits when deploying RecoverPoint with the currently available splitter types are as follows:

VNX/CLARiiON scalability

Table 8 on page 8 lists the VNX/CLARiiON scalability limits:

1. One splitter serves both storage processors of a VNX/CLARiiON array.

Maximum number of synchronous replication links per consistency group

• 1 local (FC)• 1 remote (FC or IP)

Stretch cluster distance limit (on the stretch side)

30 km

Maximum WAN packet loss 1%4

1. Where “path” is a LUN WWN seen by an RPA port. The same LUN WWN seen from different RPA ports is counted multiple times.

2. A single RPA cannot be configured to have more than 64 consistency groups. However, in the event of RPA failure, groups on one RPA will move to other RPAs in the cluster. In such a case, an RPA can temporarily hold up to 128 groups, and the data of all the groups will continue to be transferred between clusters. This state is temporary, however, as an RPA with more than 64 groups may run into high loads, and you may not be able to meet your group policies.

3. More groups can be supported. Consult EMC Customer Support for setting a minimal interval for bookmarking.

4. RecoverPoint performance and ability to meet replication policies cannot be guaranteed if WAN packet loss exceeds this limit.

New features and changes


This section lists new features and changes in RecoverPoint 4.0 and later.

New features and changes for release 4.0 P1

There are no new features in this release.

◆ Fixed problems

Table 12 on page 14 lists the problems fixed in this release.

New features and changes for release 4.0

◆ Support for data protection on up to five RPA clusters

RecoverPoint now provides the capability to concurrently protect data to multiple disaster recovery sites using a single management point. For example, data can be protected locally on one RPA cluster and concurrently copied to up to four remote RPA clusters (“fan out”), or replicated from up to four remote RPA clusters to one, central RPA cluster (“fan in”). For installation and deployment information, refer to the EMC RecoverPoint Installation and Deployment Guide. For administration and replication configuration information, refer to the EMC RecoverPoint 4.0 Administrator’s Guide.

◆ Virtual RPA (vRPA) with VNX splitter

vRPA is a virtual RPA that runs as a virtual machine on VMware ESX servers. Almost all RPA functionality is available in vRPA with little or no additional limitations. Instead of HBAs and Fibre Channel, the vRPA uses iSCSI over a standard IP network; therefore, there are no hardware requirements for the vRPA other than a standard ESX server. For installation, deployment, and operating instructions, refer to EMC RecoverPoint vRPA Technical Notes.

◆ SRM AnyPIT

SRM AnyPIT enables VMware Site Recovery Manager to access point-in-time images, not only the latest RecoverPoint image. Use EMC Virtual Storage Integrator 5.5 for RecoverPoint from within the vCenter to select the image. Refer to Virtual Storage Integrator documentation for instructions.

◆ Replicating the same device with both SRDF and RecoverPoint

From RecoverPoint 4.0 and later and Symmetrix Enginuity 5876 Q2 2013 SR and later, it is permitted to replicate the same device with both SRDF and the RecoverPoint Symmetrix splitter, as long as SRDF and RecoverPoint are replicating to two different devices, and RecoverPoint is replicating only to a local copy. For details, refer to the EMC RecoverPoint Deploying with Symmetrix Arrays and Splitter Technical Notes.

◆ Scale and performance improvements

• Maximum replication throughput for a distributed consistency group, over Fibre Channel or WAN, is now 400 MB/s.

• A RecoverPoint system supports up to 8K production volumes, when using VNX splitters with VNX OE for Block later than 05.32.000.5.201, and when using VPLEX splitters with VPLEX GeoSynchrony 5.2.



◆ Intelligent fabric-based splitters (Brocade and SANTap) and host-based splitters are not supported with RecoverPoint 4.0.

◆ Unisphere for RecoverPoint (new Management Application GUI)

The RecoverPoint GUI, renamed to Unisphere for RecoverPoint, has been completely re-developed using Adobe Flash technology and simplified to promote ease of use and a common user experience between RecoverPoint, VNX, VPLEX, and Symmetrix products.

The new protection and recovery wizards have been streamlined and optimized for a simpler and more intuitive user experience. User inputs have been reduced, more default values have been added, preferred RPAs are automatically defined, and a dashboard has been added to provide an overall view of the system health status.

Furthermore, all of the information displayed in the new GUI is consistently auto-refreshed and the new GUI is aligned with Unisphere’s internationalization support. Detailed information can be found in the EMC RecoverPoint 4.0 Administrator’s Guide.

◆ RecoverPoint/SE is now customer upgradable

With the release of Deployment Manager 2.0, RecoverPoint/SE 3.5 and later releases are now customer upgradable. The upgrade process has been greatly simplified and customers can now perform the RecoverPoint/SE software upgrades on their own schedule and without the need to schedule and rely on external resources. To perform the upgrade, you must download the RecoverPoint/SE Upgrade Kit and follow the instructions in the RecoverPoint/SE Upgrade Guide contained within the kit.

To download the kit from EMC Online Support (http://support.emc.com), click “Support by Product” and type “RecoverPoint SE” in the “Find a Product” search field. On the “RecoverPoint SE” page, the kit is located in the “Recommended Resources” section.

◆ Deployment Manager 2.0

Deployment Manager 2.0, which replaces Deployment Manager 1.1, introduces a number of changes and new features, including a new wizard to connect RPA clusters running release 4.0, the ability to install virtual RPAs, and integration with EMC Online Support site for upgrades. Furthermore, as of 4.0, deployment operations—such as installation, upgrade, and modification—are performed per RPA cluster, not per system. Refer to the RecoverPoint Installation and Deployment Guide and RecoverPoint Deployment Manager 2.0 Release Notes for more information.

◆ REST API access to the RecoverPoint functional API

The REST API provides a simple-to-use Web interface to the RecoverPoint API that third-party developers can use to integrate RecoverPoint functionality into their own applications and to script RecoverPoint operations. The REST API is documented in the EMC RecoverPoint 4.0 REST API Programming and Reference Guide.

◆ SyR improvements

A new schema has been developed that supports the new RecoverPoint multi-cluster and eLicensing features, doesn't change whenever a class in the schema changes, and only contains fields that are required by SyR clients. When testing connectivity, the user is now prompted for a verification email address. If the connectivity test is


http://support.emc.com


successful, a service request containing call home event number 30999 is opened and an email is sent to the entered email address from EMC Customer Support to verify that the system reports mechanism (SyR) has been successfully configured.

◆ Lag Optimizer

Priority of bandwidth allocation for consistency groups has been improved to substantially minimize any business damages that customers may incur due to data loss in the case of an actual disaster.

◆ Licensing improvements

This feature introduces eLicensing. For existing RecoverPoint users, this enhances license tracking and management, improves overall user experience, enables less complex license upgrades, reduces the risk of non-compliance, eliminates the paper right-to-use (RTU) cards, and enables self-service license creation. For licensing information, refer to the EMC RecoverPoint 4.0 Administrator’s Guide.

◆ Journal and repository volumes can now be located on non-licensed arrays

In RecoverPoint/SE and RecoverPoint/EX, journal and repository volumes can now be located on non-licensed arrays.

◆ Support for sync over IP

RecoverPoint now supports synchronous replication over IP to a remote RPA cluster.

◆ FIPS 140-2 compliance

The following FIPS (Federal Information Processing Standard) 140-2 validated cryptographic modules are used in RecoverPoint 4.0:

• RSA BSAFE® Crypto-J, JSAFE, and JCE Software Modules• RSA® BSAFE Crypto-C Micro Edition• OpenSSL FIPS Object Module

For more information about RecoverPoint security, refer to the EMC RecoverPoint 4.0 Security Configuration Guide.

◆ User experience enhancements

Many improvements have been made to ensure a better overall total customer experience in RecoverPoint 4.0:

• Splitters residing on licensed arrays are automatically added to the system.

• When recovering production, there is no longer a need to enable image access to the production and resume production.

• Snapshots now carry a consistency tag that enables the user to mark snapshots that are known to be application-consistent as such. Snapshots created using KVSS are automatically marked as application-consistent.

• Image access is now part of the flow of the recovery wizards and is no longer performed as a separate function. An image access progress indicator and an image access log capacity indicator have both been added to the recovery wizards.



• Users can now select an event in the event log and click “Collect System Information” to open the Collect System Information wizard and RecoverPoint will automatically set the collection start time and end time fields to 10 minutes before and after the selected event.

• Additional RPA cluster information has been added, including; the RecoverPoint version, RPA type (physical or virtual), number of RPAs in the cluster, cluster management (LAN) IPv4 and IPv6, and the time zone of the RPA cluster.

• Bottleneck detection and load balancing analysis are now available from the GUI.

◆ Read access to replication volumes

When using VNX or Symmetrix splitters, 4.0 supports read access to replication volumes at local and remote copies, without disrupting normal distribution of replicated data to the same volumes. As a result, the Cluster Shared Volumes feature is supported for consistency groups managed by RecoverPoint/CE 4.1.3 or later, for which “read-only” is the default splitter setting. Note that when in read-only mode, consistency and data integrity of the copy volumes are guaranteed only if the user does not mount, unmount, or otherwise manipulate those volumes. For other groups, “fail-all” continues to be the default splitter setting.

◆ Multipathing performance and robustness improvements

In 4.0, multipathing performance and robustness is improved, thereby simplifying the procedure for changing the mapping of LUNs that have already been exposed to RecoverPoint. This feature is implemented both with FC and iSCSI protocols.

◆ Fixed problems

Table 13 on page 15 lists the problems fixed in this release.

Table 12 Problems fixed in RecoverPoint 4.0 P1

Issue number Product feature Problem summary

35612 Deployment Manager

When using the Deployment Manager Add New RPAs Wizard to add an RPA to an existing RecoverPoint/SE RPA cluster, the addition will fail with the error, “Unable to execute command.”Workaround: Manually register the new RPA initiators on the VNX/CLARiiON array, and add them to the relevant storage groups.

35342, 35469

Deployment Manager

When using the Deployment Manager Upgrade RPAs Wizard to upgrade a system running 3.5.x, and with no WAN gateway configured, to 4.0, the upgrade will fail.Workaround: Before the upgrade, configure a WAN gateway.

35003 Deployment Manager

When using the Deployment Manager RecoverPoint/SE Installer Wizard to reinstall 4.0 on a system that was already running 4.0, the installation will fail with an error stating that there is no IP connection between RPAs and storage.Workaround: Contact EMC Customer Support for assistance.

35708 System After upgrading a one-cluster (one-site) RecoverPoint system from 3.5.x to 4.0 using Deployment Manager Upgrade RPAs Wizard, reboot regulation will occur.

35673 System When in physical or virtual image access mode and: a) a flipover occurs, or b) the replication process crashes, an inconsistency may occur.

35438 System The RecoverPoint getVolumeInformation Functional API method may return an incorrect naaUid, which may affect users that use this field, which is part of the VolumeInformation object.

35377, 35430, 35476

System When sending write(16) SCSI commands for some offsets (which usually occurs when working with LUNs greater than 2 TB in size), you will be unable to replicate consistency groups with these LUNs (the groups will go into a regulation state).

35079 System When performing an upgrade while throttling level is enabled (high or low), or enabling throttling level after installation, replication will get stuck during initialization.Workaround: Disable throttling level.

35684 System After performing an upgrade from 3.5.x to 4.0, one of the following will occur on the remote site:• When using automatic snapshot consolidation, the RPAs will eventually enter reboot

regulation• When using manual snapshot consolidation, the replication process will restart.Workaround: Disable snapshot consolidation.

35690 VMware SRM When using VMware SRM AnyPIT, the SRM test failover feature fails with errors when the protected and recovery sites are disconnected.

35126 vRPA After cloning a virtual RPA (vRPA), the cloned vRPA does not have a network interface defined, causing it to spontaneously reboots in a loop every couple of seconds, making it unusable. Workaround: Use OVF package to deploy a new vRPA.


Fixed problems

Table 13 Problems fixed in RecoverPoint 4.0 (page 1 of 4)


34762 Array splitter specific

Only relevant when using RecoverPoint 4.0 and VPLEX GeoSynchrony 5.1When the RecoverPoint Client calls the VolumeInformation object, getPaths() method, the re-turned list is always empty. No information is available on VPLEX and RecoverPoint integration.


In a Symmetrix splitter environment, when the splitter tries to query the array regarding an ORS state when no ORS session exists on the array, the splitter will crash.


When resizing Replication Set while disabling a consistency group, the relevant copy locks in REGULATED state instead of DISABLED state.Workaround: Remove the Replication Set that is being resized (the problematic RSET).


In a RecoverPoint/SE environment, running the get_system_settings CLI command leads to the repository volume information not being displayed properly in the command output. As a result, when using, for example, the Deployment Manager Converter Wizard, this problem will cause the conversion to RecoverPoint to fail.


In a Symmetrix splitter environment, Open Replicator Sessions do not support LUNs that are ex-posed to more than 32 FAs. If a LUN in a RecoverPoint replication set is attached to the Symme-trix splitter, and exposed to more than 32 FAs, it will stop the Symmetrix splitter (replication of the entire consistency group will fail).


In a VNX splitter or VMAX splitter environment, during unmapped data (punch) distribution, rep-lication process may constantly crash when only unmapped data is replicated (since the meta-data pool is entirely consumed), and initialization does not progress.Workaround: Contact EMC Customer Support for a signed script.


In a Symmetrix splitter environment, even though volumes may be detached, generic warnings for the volumes may still appear in the RecoverPoint GUI.


In a RecoverPoint/SE environment, due to a CLI issue, the interface with Celerra does not work, leading to a failure to replicate on a file level.


In a system converted to RecoverPoint/SE where the array has many storage groups, the user may fail to change system settings (such as creating a new consistency group), indicated by the UI getting stuck until a timeout occurs. Workaround: Contact EMC Customer Support for a tweak.


When performing SRM failover (migration) on multiple consistency groups, RecoverPoint may re-turn conflicting states, causing SRM actions to fail.Workaround: Resolve the settings conflict manually, and then re-activate SRM.


In a Symmetrix splitter environment, when the ACA bit is set on the device, the RPAs will be un-able to see the device. As a result, RecoverPoint will present a configuration error even though the configuration is OK. Workaround: The error can be ignored.


When using a VPLEX splitter, the snapshots, bookmarks, and other features are unavailable when rebuilding a distributed volume on a RecoverPoint protected VPLEX Metro cluster. This is due to a physical link error or a non-operating VPLEX cluster. The RPA reports the consistency group is in ERROR instead of INIT state. Workaround: None: Consistency group returns to INIT or Active state once un-order writes have completed.

29980, 30126

Array splitter specific

VNX/CLARiiON Splitter fails when reading or writing in virtual access or virtual with roll. This causes an SP panic on the VNX/CLARiiON array.Workaround: Do not use virtual access or virtual with roll.


Deployment Manager (DM) cannot upgrade RecoverPoint with consistency groups with names that end with back-slash (\). Workaround: Rename the consistency groups, removing the back-slash (\).


Fixed problems

34208 System During initialization, if transfer of a consistency group is stopped for some reason (for example, due to high load), and the group has compression configured, there is a low probability that the RPA running the consistency group may fail with assertion, and as a result a short initialization may occur on all the consistency groups running on this RPA.

34152 System When a fatal error occurs during virtual access, the RPA cluster may detach because of RPA repli-cation processes crashing in a loop.

33946 System There is a low probability that during snapshot consolidation a fatal error may occur and will cause a full sweep and journal loss.

33815 System If distributing a large-sized image during a pause distribution (the large image may occur during an initialization), and at the same time the system tries to remove this image due to a lack of space, the journal may become corrupted and the journal history will be cleared and a full sweep will occur.

33461 System When I/O throttling is enabled, reboot regulation may occur.Workaround: Disable I/O throttling if this problem occurs.

33309, 33336

System Resizing LUNs may cause errors or loss of journal, returning a “fatal error” or “journal loss” mes-sage. This may occur when journal space is used up and the journal mus be resized.Workaround: None. Reduce the chances for error by setting journal lag after the most recent LUN resize and before a planned reboot or NDU user action.

33219 System When creating a consistency group using the Consistency Group Wizard, together with Auto-pro-visioning journal, the complete name (cgName + copyName + internalSiteName) cannot be lon-ger than 64 characters.Workaround 1: Define short consistency group and copy names, so that the complete name is up to 64 characters,Workaround 2: Create journal volumes manually.

32113 System During unmapped data (punch) distribution, replication process may constantly crash when only unmapped data is replicated (since the metadata pool is entirely consumed), initialization does not progress.Workaround: Contact EMC Customer Support for a signed script.

32074 System If a communication disaster occurs during synchronous replication of a distributed consistency group, and immediately afterwards an FC disaster occurs on the remote site, the replication process of the primary RPA will get stuck, and after a number of minutes the replication process will restart. This will result in a short initialization of all consistency groups running on the RPA.

31949 System In a VMAX or VNX splitter environment that support thin LUNs, when a long resynchronization occurs, the replication process may generate massive amount of logs. These logs probably cause the replication process to get stuck and to restart after a number of minutes. This action will result in a short initialization of all consistency groups running on the RPA.

31914, 32914, 34276

System In a heavily loaded environment, the control process may crash, causing reboot regulation. The UI temporarily loses connection with cluster control. User initiated operation may fail.Workaround: Reboot RPAs 2-8 to resolve the problem until the next occurrence.

31845 System When a sudden, small I/O burst occurs (for example, 1.5 GB), a high load may occur.

31546, 34732, 34839

System In a RecoverPoint system connected over Fibre Channel (not iSCSI), an RPA might get stuck or suddenly reboot, causing one or more RPAs in the cluster to crash.

31252 System Due to a storage awareness issue, when I/O throttling is enabled, the replication process may crash, leading to RPA to enter reboot regulation.Workaround: Contact EMC Customer Support for a tweak.




Fixed problems

31215 System After installation, a settings conflict (probably due to improper installation process) occurred that was resolved improperly by the user taking the empty settings. This action causes the inter-nal process to crash and restart. Workaround: Contact EMC Customer Support for a tweak.

31054 System In the following scenario, you will not be able to connect to the RecoverPoint UI, and eventually the RPAs will enter reboot regulation:1. Add a new replication set to a consistency group, with no volumes in it.

2. Add a replication volume to the replication set, in the replica copy.

3. Add a replication volume to the replication set, in the production copy.

Workaround 1: Before the issue occurs, add the replication volume of production copy to the replication set before adding the replication volumes in the replica copy.Workaround 2: After the issue occurs, remove the relevant consistency group and add its set-tings according to the order above (production volume first).

30965 System In a RecoverPoint system connected over Fibre Channel (not iSCSI), a high I/O rate may cause the replication process on the remote site to restart, causing a short initialization. Workaround: Contact EMC Customer Support for a tweak to reduce the probability of the issue occurring.

30808 System When integrating a new RPA or replacing a disk in an existing RPA, installation may fail, raising failure mode (shell). The installation process appears stuck.Workaround:1. Reboot and try installing again from the installation DVD.2. Connect a KVM switch and try installing from another instance of the Installer Wizard.

30673 System In a system with high latency between sites and deduplication is configured for a certain link, and the transfer over the link is paused and started, replication process may crash and a short initialization will occur of the consistency groups running on the specific RPA.

30515, 34666

System Trying to add a second VMware vCenter Server to the same site will fail and display the error message "Error: Invalid port or certificate", even when the port and certificate are valid.Workaround: Reboot RPA or Tomcat to reload the keystore. To add several connections with sev-eral certificates, first add all the credetials with all the certificates to the keystore, then restart Tomcat to reload all the new certificates.

30489 System There is a low probability that during snapshot consolidation a fatal error may occur and cause a full sweep and journal loss.

30365 System When replicating asynchronously over Fibre Channel (FC), and the FC connection is slow, this may cause transfer to start and pause repeatedly. As a result, the replication process may lose memory, causing the replication process to crash.

30309 System Using the Installation Manager (boxmgmt), when attaching RPA1 and you enter the current local time, the input is applied in GMT time. This results in bookmarks appearing in the incorrect time zone. Workaround: When attaching RPA1, enter the GMT time instead of the local time.

29578 System In a CDP or CRR configuration, if you add a copy to a consistency group when the replication task is closed, journal loss and a full sweep on the relevant consistency group will occur. Work-around: Do not add a copy when transfer is in “N/A” state. Fix the problem, wait for transfer to be in any other state than “N/A” and then add the copy.

29470 System If you try to configure more than 1024 replication sets in a consistency group, RPAs will enter re-boot regulation. Workaround: Divide the consistency group with more than 1024 replication sets into two groups. Do this also before upgrading to 3.5.




Fixed problems

29220 System In an environment with at least 3 RPAs with a distributed consistency group with at least 3 pre-ferred RPAs, in case of within-site FC connectivity problems between two RPAs, replication will not start. Workaround 1: Fix the connectivity problem.Workaround 2: Define different preferred RPAs.

29205 System In a scaled environment, where SAN Discovery might take some time, if volumes were not ex-posed to an RPA and then many new volumes were exposed to an RPA just prior to installation, installation will be blocked and user will see error “SanView is empty”.

Note: In a VPLEX environment, the maximum number of volumes for VPLEX deployment per VPLEX cluster is 5K.

Workaround 1: Wait until SAN Discovery finishes, then perform installation. Workaround 2: Avoid exposing many new volumes to RecoverPoint prior to installation.

29128, 29170

System In an environment where replica storage is a bottleneck and there is low journal size, a high write rate may lead to a journal loss in replica and full sweep afterwards. The probability of this problem occurring increases when there are sync and async links in the same direction. Work-around: Use a larger journal, or restrict journal lag by some value.

29099 System If a Fibre Channel disaster occurs when a distributed consistency group is replicating synchro-nously, transfer will go down (display “N/A”) for a number of minutes. Afterwards, the RPA will automatically recover and an initialization will occur.

26171 System Initialization restarts, high latency for user I/Os, and possibly aborted I/Os may occur in the fol-lowing scenario:• Initialization in synchronous replication mode• “Measure lag when writes reach the target RPA” setting (in Consistency Group Advanced Pol-

icy of the RecoverPoint GUI) or measure_lag_to_box parameter (in the set_policy CLI com-mand) equals “No”

• relatively high write rate on the production copySpecifically, near the end of the initialization, host I/Os will not be acknowledged for a consider-able period of time, which may cause the host to abort an I/O. The abort will cause the system to stop responding to writes for several seconds, after which an initialization will start again. It is possible that this behavior will reoccur.Workaround: Set the “Measure lag when writes reach the target RPA” setting or the measure_lag_to_box parameter to equal “Yes”.




Environment and system requirements

Environment and system requirements

Generally, RecoverPoint hardware and software components are installed by EMC personnel. Specific requirements by both EMC and the customer are expected to be addressed before the equipment is shipped to the customer site. However, as mentioned in “RecoverPoint/SE is now customer upgradable” on page 11, customers can now access RecoverPoint software and perform their own upgrades.

End of service dates and extended support

EMC has a standard software support duration policy which specifies that a major version will reach End of Service Life (EOSL) a minimum of 36 months following the General Availability (GA). EOSL may be followed by an Extended Support period during which customers may elect to pay an additional fee to extend their support coverage rather than migrate to a current software version.

Once a software product reaches EOSL, EMC Technical Support is no longer available under base support/maintenance agreements. Customers interested in uninterrupted support must upgrade to a current release or contract for Extended Support.

EMC Online Support site contains a list of documents that provide end-of-service and extended support information for EMC software and hardware products.

To access these documents on EMC Online Support:

◆ Go to EMC Online Support, at http://support.emc.com.

◆ Go to Support by Product pages and search for RecoverPoint CL.

◆ In the product page, scroll down the left and click Release and End of Life Dates.

◆ Find the EMC Software Release and End of Service Life Notifications document in the results.

◆ Open it and search for your product and version.

This document provides EOSL dates for EMC software products.

Note: This policy is in effect for select releases and will be phased in as new versions are made available. In cases where a software release is not eligible for Extended Support, the previous policy, which specifies product support and maintenance under Continuous Coverage Product Maintenance (CCPM), terms still apply.



Known problems and limitations


This section lists the limitations and known problems in the current RecoverPoint release.

Note: All information regarding interoperability limitations is available on E-Lab Navigator.

Limitations

RecoverPoint 4.0 and later releases have the following limitations:

◆ To remove an RPA cluster, the Installation Manager (boxmgmt) must be used.

◆ Gen5 (Intel) RPAs support BMC and RMM4. Gen4 RPAs support Dell iDRAC, OMSA, and the Dell MIB.

◆ When setting a consistency group as distributed, the capacity of the group's copy journals should not be less than the minimum journal size required for distributed groups. Adding journal volumes for such groups necessitates a disabling and re-enabling of the consistency group, which causes a full sweep.

◆ There is a small improvement in performance when a distributed group is run on three RPAs. A steep improvement in performance is experienced when the group is run on four RPAs.

◆ All IP addresses in the RecoverPoint system (that is, RPA, Management (LAN), and WAN/Private IP addresses) must be unique within the RecoverPoint system, even if they are not on the same subnet and there is no routing between them.

◆ RecoverPoint supports thin provisioning only on all EMC arrays and on Hitachi arrays.

◆ AVT failover mode is not supported on all storage arrays.

◆ The RecoverPoint multi-WWN (virtual ports) feature requires that the fabric switch supports arbitrated loop capability.

◆ RecoverPoint is supported in environments that utilize VLAN tagging (802.1q). RPAs do not tag the traffic that they send.

◆ RecoverPoint is not supported in environments that utilize IP L2 prioritization (802.1p).

◆ RecoverPoint is not supported in environments that utilize Differentiated Services Code Point (DSCP) Quality of Service (QoS).

◆ RPAs on one cluster may not be able to communicate with RPAs on another cluster if there is a network address translation (NAT) firewall between the clusters.

◆ Unisphere for RecoverPoint may not be able to communicate with RPAs if there is a network address translation (NAT) firewall between the machine that runs the GUI and the RPAs.

◆ RecoverPoint/CE 4.1.3 and later supports replication for continuous remote replication consistency groups and continuous local and remote consistency groups. For the latter groups, however, failover is supported only to a remote copy, and failback will always be to the original production copy.



◆ In a RecoverPoint environment with Windows Server 2003 Enterprise running Exchange 2007 Cluster Continuous Replication with Majority Node Set Quorum, RecoverPoint VSS utilities (KVSS) will fail to install due to a known MSDTC limitation in a non-shared Quorum configuration (MNS).

Note: This limitation is resolved in Windows Server 2008 and later releases.

◆ The number of snapshots that can be taken is unlimited. However, when selecting an image from the list in the Enable Image Access dialog box (RecoverPoint GUI), a limit of 1013 snapshots (images) are presented.

◆ VMware ESX replication capabilities and limitations are specified in EMC RecoverPoint Replicating VMware Technical Notes.

◆ When using VNX/CLARiiON splitters:

• In certain configurations, consistency groups cannot include Solaris-based hosts replicating data on heterogeneous arrays. Refer to the ESM for supported configurations.

Note: Consistency groups can include Solaris-based hosts replicating data on heterogeneous arrays when the Solaris-based hosts use VxVM.

• RecoverPoint replication and MirrorView replication cannot concurrently operate on the same volume.

• If MirrorView is installed on a VNX/CLARiiON array, RecoverPoint cannot utilize the ports reserved by MirrorView. MirrorView must be disabled before the RecoverPoint splitter driver can be enabled.

• When multiple RPA clusters share a VNX/CLARiiON splitter pair (CX3 models running FLARE 03.26 or later, CX4 models running FLARE 04.29 or later, and VNX OE for Block models running 05.31 and later), and are running on the same array, each RPA cluster must have a unique name.

◆ RecoverPoint volumes—repository, journal, and replication—should not be configured on CLARiiON CX4 disk drives with FLARE 29 or later installed that have spin-down capability.

Normally, RecoverPoint will prevent volumes protected by RecoverPoint from spinning down; however, if a volume does spin down, an error will be raised until the volume spins up again.

◆ It is recommended to run only a single consistency group in virtual image access mode using the same RPA.

◆ RecoverPoint does not currently support WAN accelerators, unless the device is specifically supported in the EMC Support Matrix with RecoverPoint. EMC is aware of configurations in which performance is degraded when using WAN accelerators in conjunction with RecoverPoint, such as when enabling compression on both RecoverPoint and the WAN accelerator.

◆ When replicating a Microsoft VSS image, attempting to access an image on the target-side image when there is an MSCS cluster at the target side, and the replication volumes are resources in the target cluster, the replicated disk on the target side will not be visible to the MSCS cluster.



◆ For VNX/CLARiiON arrays, each storage group can support a maximum number of volumes, based on the storage system and the storage operating environment. RecoverPoint can replicate more volumes per VNX/CLARiiON array by using virtual WWNs.

◆ The Predicted Protection window feature is not supported when the current protection window is less than 24 hours.

◆ The CLI script converter (the convert_script CLI command) does not support the conversion of measure_lag_to_box parameter from 3.4 or earlier scripts. When loading the converted CLI script into the new environment, each consistency group will be created with value of Yes for all group links, unrelated to the value of this parameter in the old environment.

Known Problems

Table 14 on page 22 lists the known problems found in RecoverPoint 4.0 and later.

Table 15 on page 23 lists the known problems found earlier than RecoverPoint 4.0.

Where a problem is only relevant to a specific RecoverPoint release, it is noted in the problem summary.

Table 14 Known problems found in RecoverPoint 4.0 and later

Issue Number Product Feature Problem Summary


If you try to reinstall a RecoverPoint/SE environment from scratch (including formatting the re-pository volume) without running the clear_settings CLI command beforehand, a generic warn-ing will appear stating that devices are attached to another cluster, and replication won't start. Workaround: Contact EMC Customer Support for a procedure to resolve the issue.


When a user adds volumes to the same copy of the same consistency group, but from different clusters, and the volumes are added simultaneously or when the WAN is disconnected, the number of volumes can exceed the maximum number supported by the splitter. Control at-tempts to add the volumes to the splitter until the consistency group is regulated.Workaraound: Detach volumes from the splitter until the number is within the maximum al-lowed.

35289 System In a high throughput environment, specifically with large journal lag, replication may stop on all consistency groups running on the RPA.

34676 System When cluster control comes up, the settings may not yet be loaded when usersystem tries to useing them, causing control process to crash and restart.

34537 System No warning is issued when configuring RPAs that do not exist in all the copy sitesclusters. As a result, another RPA, not the preferred RPA, will be used for replication of the group copy.Workaround: Before configuring the RPAs, verify that the designated RPAs are responding from all copy sitesclusters. After configuring the RPAs, review RPA settings, verifying all RPAs are ac-counted, with no missing copy sitesclusters.

32271 VMware VMware ESX Virtual Machine does not shut down when shutting down the RecoverPoint Appli-ance (RPA) using the “boxmgmt” CLI command.Workaround: Shut down VMware ESX Virtual Machine and RecoverPoint Appliance manually.

34636 vRPA In a vRPA environment, when the iSCSI IPs of all RPAs are changed at the same time, an unex-plained reboot may occur.Workaround 1: Detach all RPAs before changing their iSCSI IPs.Workaround 2: Change the IPs of each RPA one at a time. For example, verify that RPA 1 is ex-posed to the repository before changing the IP of RPA 2.



Table 15 Known problems found earlier than RecoverPoint 4.0 (page 1 of 3)


14681 System When Snapshot Consolidation is enabled:• The Predicted Protection Window information is unavailable.• The Current Protection Window Status may be incorrect.

23813 System When replicating remotely over Fibre Channel, if you reinstall the environment and change the RPA roles (such as change R1 to R2 and R2 to R1), the remote RPAs will lose their WAN connec-tion to the local site. Workaround: If the RPAs are up and there's no communication between the sites, reboot all RPAs again. The situation will correct itself after approximately 15 minutes.

23847 System When using the Installation Manager (boxmgmt), running signed scripts that require user input will cause the system to hang (system will show “Please wait...”) until you end the command.

24326 System When upgrading to a new RecoverPoint version that introduces a change in the system-defined call home events, the new system-defined events will override the old ones, but any user-defined call home events will be lost. Workaround: Save the user-defined call home event rules and add them again after upgrade.

25126 System After performing the following actions, the display in the GUI and CLI is confusing:1. Detach volumes from a splitter.

2. Remove the splitter.

3. Uninstall the splitter on the host.

4. Connect to add splitter in the GUI.

5. Install splitter (new version) on the host.

The GUI will display the same splitter twice, and the CLI command add_splitter will fail with the message “Error: Splitter names appear more than once on network”. Workaround: Wait around 30 minutes, after which you will be able to add the splitter successfully.

25483 System When you run CLI commands from RPAs which are not site control RPAs (RPA1 and RPA2), you may get the wrong output for some commands related to SAN view and to statistics.Workaround: Run the CLI commands from RPA1 and RPA2.

29504 System If you change several consistency groups (CGs) from distributed to non-distributed, and vice versa, at the same time, distributed CGs-non-distributed CGs transition will not complete, and transfer will pause. Workaround 1: Change CGs to be distributed or non-distributed one at a time. Workaround 2: Kill all replication processes, one at a time. Workaround 3: Reboot RPAs one at a time.

30580 System When the Intel Integrated Baseboard Management Controller (BMC) or the Integrated Dell Re-mote Access Controller (iDRAC) is disabled using the Installation Manager (boxmgmt), only the Intelligent Platform Management interface over the local area network (IPMI over LAN) access is actually disabled. It will still be possible to access BMC or iDRAC via its IP address, even when it is disabled in the Installation Manager.Workaround: To completely disable access, set all IP addresses that provide access to these services to 0.0.0.0. For iDRAC, it means setting the LAN IP address to 0.0.0.0. For BMC, it means setting the LAN, WAN, and BMC port IP addresses to 0.0.0.0. This procedure is not recommended, as it disables all network access.


Working with CLARiiON Splitter and “domino” configuration, a host application performs I/O to RP protected LUNs and the Active CLARiiON SP reboots. After the Active CLARiiON SP restarts, the host application may experience I/O errors.




3.4 SP1 and laterUsing a Symmetrix splitter, when replicating synchronously and there is a failover during writes at the new active site, failover will be followed by a short initialization.Workaround: Stop writes before performing failover. Start writes after failover completes.

29313, 29770

Array splitter specific

In a RecoverPoint/SE environment, changing the site management IP (floating IP) will cause the RecoverPoint plugin in the Unisphere/Navisphere UI to stop working.Workaround: Manually change the IP address of the RP initiator on the VNX/CLARiiON array. The initiator ends with 0_0 and contains the previous site management IP.

27796 System Changing a site name does not change the site name seen in volumes list of Configure repository volume of Installation Manager (in boxmgmt Setup menu). You will always see the site name that was configured at the moment of installation or upgrade.

26393 System Defining “info” level filtering for syslog notification only shows “info” event logs and does not display higher level event logs (“errors” and “warnings”). Workaround: Define filters for “warn-ing” and “error” levels.

33472 System When running a CLI script on a large scale environment (8000 volumes, 128 consistency groups), the GUI does not open, waiting for the script to complete.Workaround: Wait for the CLI script to complete, or stop it in the middle to open the GUI.

30367 System When creating an LDAP type user, the new user cannot be limited to a specified consistency group.

28255 System When the SMTP server is not defined, sending a SyR report fails, returning the error "Failed to send email".Workaround: Define the SMTP server.

34834 System When opening multiple GUI sessions on the same computer and browser application, the follow-ing problems may arise:1. The RecoverPoint API may reach a different GUI session than the one that called the API. 2. An open session may disconnect for several seconds if another session fails to log on.3. A non-existing user may succeed logging on to RecoverPoint.4. A false disconnection error message may appear.Workaround: When opening several sessions on RecoverPoint from the same computer, use dif-ferent browser applications.

34181 System When trying to download logs using Microsoft Internet Explorer 8, the following error appears: “unable to open this internet site..”Workaround: To download the logs, upgrade Internet Explorer to version 9, or use Firefox or Google Chrome.


When using a VNX/CLARiiON splitter and running the get_splitter_settings CLI command, the output shows SAN information for splitter B as “N/A”, even when splitter B is working fine.Workaround: See the output of splitter A, since it is identical to splitter B.


When using a VPLEX splitter, if the splitter volume state is in target-side processing (TSP) mode and replication reaches TSP full, a full sweep will be triggered. A full sweep will also occur in the following scenario: If an RPA fails to respond to I/Os from the VPLEX splitter for more than 5 min-utes (for example, due to a journal error issue).




Technical notes

Technical notes

This section contains important information for the current release.

Upgrading to the latest RecoverPoint 4.0 release

Upgrade to the latest RecoverPoint 4.0 release in order to resolve the issues listed in “Fixed problems” on page 14. Upgrades are performed using Deployment Manager 2.0.

It is recommended to upgrade all relevant splitting technologies only after all RPAs have been upgraded to the latest 4.0 release.

Instructions for upgrading are detailed in the EMC RecoverPoint Installation and Deployment Guide. Information about Deployment Manager 2.0 can be found in the EMC RecoverPoint Deployment Manager 2.0 Release Notes.

Licensed features

When upgrading to RecoverPoint 4.0, previous licenses will automatically be converted to the new license format. However, the new licenses are temporary and valid for 90 days from the date of upgrade. After that, you must have installed one or more permanent license files to replicate with RecoverPoint. Instructions for licensing are detailed in the EMC RecoverPoint 4.0 Administrator’s Guide.

Licensed features in RecoverPoint 4.0 and later: None.


When configuring VPLEX credentials, if you enter a valid username, password, and IP of a VPLEX platform, but the VPLEX platform with the IP you entered is NOT part of the RecoverPoint environ-ment:• the credentials validation will incorrectly pass successfully.• RecoverPoint will not function in the VPLEX UI (disabled in the manager menu).• RecoverPoint log collection won't collect logs from the correct VPLEX splitter.• RecoverPoint will filter VPLEX volumes only for the VPLEX platform of that with the incorrectly

entered IP; if there is an additional VPLEX platform on the same site with valid and correct cre-dentials (that is, the IP address matches the VPLEX splitter), its volumes won't be filtered out.

Workaround: Enter the correct IP of the VPLEX platform in the RecoverPoint environment.


VNX/CLARiiON splitter does not support Punch commands, on both virtual and physical image access.


When I/O between the Symmetix splitter and the RPA fails, the RPA begins tracking and receiving the backlog from the splitter. Performing a failover before backlog retrieval has completed causes data data inconsistency between the RPA and splitter.Workaround: Clear journal markers to initiate a full sweep replication.

35016 System When a user changes a tweak and later the tweak is changed again in a new release, then, after upgrading to the new release, the user change is ignored and there is no notification that the change is not applied. Workaround: Reboot site control in production, change the tweak again.

28413 System When an LDAP user has a boxmgmt role, the LDAP user is not fully functional.
