Whats New in the OSIT requirements are changing. Todays multi-tenant, mixed-workload environments are moredemanding than ever. New HP 3PAR OS 3.1.3 delivers Tier 1 performance and quality of service(QoS) in a system that is more scalable than ever before to exceed the requirements of the mostdemanding hybrid and private cloud environments.HP 3PAR OS 3.1.3 features include the following benefits:

Assured QoS and resiliency enhancements

Flash storage optimization

Increased scalability

Remote Copy enhancements

Federated technologies

New drive support

Online Upgrade Considerations 5

Interoperability

Enhanced Thermal Shutdown

Options for HP 3PAR OS Software Upgrades

Assured QoS and resiliency enhancements

HP 3PAR StoreServ StorageHP 3PAR Priority Optimization now provides the ability to set minimum goals and maximum limitfor IOPs (that is performance) and bandwidth. You can define Latency Goals for the mostmission-critical applications. To ensure that the latency goals are achieved, the system automaticallyadjusts the service levels of lower-priority applications and workloads and ensures that the necessaryQoS levels for highest priority applications are maintained. With the combination of PriorityOptimization and Virtual Domains, you can specify these thresholds to protect individual tenantsand to prevent a single tenant from monopolizing resources. These capabilities allow you to deliverassured QoS levels without having to physically partition resources or maintain discreet storagesilos thus eliminating any barrier to consolidation.Virtual Domains eliminate the last barrier to consolidation by integrating with HP 3PAR PriorityOptimization. This enables performance assurance for most mission-critical virtual domains. It ispossible to use Priority Optimization to prioritize not just an application or workload, but also avirtual domain or a tenant using the multi-tenant system such as different departments, businessunits, customers, and so on.System Reporter allows configuring user-defined alerts directly on a HP 3PAR StoreServ by usingthe SR-On-Node data.New enhanced on-node historical statistic allows the user to monitor:

Historical data reports for SSD wear gauge

Historical performance data reports for Remote Copy links

Historical performance data reports for Remote Copy volumes

Persistent Ports support is extended to iSCSI and FCoE array target connectivity. Persistent Portssupport for Fiber Channel connectivity is enhanced to provide controller node connection statusdetection. This provides protection against link loss between the array node port and the SANswitch. This supports high availability in virtualized environments by automatically failing over ahost facing controller node port that experiences link loss due to a cable or a switch failure.

Flash Storage OptimizationsHP continues to invest and lead in Flash technologies. HP 3PAR OS 3.1.3 provides the followingnew optimizations:

Higher IOPS and lower latency for HP 3PAR StoreServ 7000 systems with improved handlingof SAS interrupts

Adaptive Sparing technology implemented with new 480 GB and 920 GB SSDs to enhancetheir endurance (available on HP 3PAR StoreServ 7000 systems)

Increased ScalabilityThe increased scalability only applies to HP 3PAR StoreServ 7000 and 10000 models.

NOTE: New increased scalability numbers do not apply to HP 3PAR F- class and T- class storagesystems.

6 HP 3PAR OS 3.1.3 Release Notes

Maximum Drive SupportWith HP 3PAR OS 3.1.3 release, the number of maximum hard disk drives supported on the HP3PAR StoreServ 7200 Storage is increased. The HP 3PAR StoreServ 7200 supports up to a maximumof 240 drives and 9 add-on drive enclosures.

HP 3PAR Remote CopyHP 3PAR OS 3.1.3 release provides greater scalability and flexibility to HP 3PAR Remote Copytechnologies. This release also provides the following benefits:

Greater scalability enabling 4x4 replication topologies

Increased scalability enabling more Virtual Volumes to be replicated

Support for up to four RCFC links and one RCIP link per node

HP 3PAR Federated TechnologiesHP 3PAR OS 3.1.3 continues to lead in Storage Federation. This release adds the followingenhancements to HP 3PAR Peer Motion technology:

Non-disruptive data migration for Microsoft Windows clustered environmentsPeer Motion supports non-disruptive data migration for Microsoft Windows Server 2008, R2and Microsoft Windows Server 2012, R2 Failover Clusters. The HP 3PAR source arrays canbe at HP 3PAR OS version 2.3.1, 3.1.1, 3.1.2, or 3.1.3. The HP 3PAR destination arraysmust be running a minimum of HP 3PAR OS version 3.1.3. The maximum size of Windowsclusters supported for non-disruptive data migration is four nodes. This feature is supportedon HP 3PAR Management Console platform.

Non-disruptive data migration for Linux clustered environments.Peer Motion supports non-disruptive data migration for Red Hat clustered and SLES HAenvironments on HP 3PAR source arrays running HP 3PAR OS version 2.3.1, 3.1.1, 3.1.2,or 3.1.3 to HP 3PAR destination arrays running HP 3PAR OS version 3.1.3. To obtain moreinformation about supported configuration, see the Single Point of Connectivity Knowledgefor HP Storage Products (SPOCK) website:http://www.hp.com/storage/spock

Single Volume MigrationPeer Motion in HP 3PAR OS 3.1.3 allows online migration of individual volumes exported toa host. This eliminates the need to unzone a host from the source array and provide loadbalancing by migrating only a subset of volumes assigned to the host from a source 3PARarray. Both the source and destination arrays must be running HP 3PAR OS 3.1.3.

SupportHP 3PAR OS 3.1.3 is the last major HP 3PAR OS release to support data migration via PeerMotion with source systems running HP 3PAR OS 2.3.1.

HP 3PAR Online Import EnhancementsWith HP 3PAR OS 3.1.3 release, HP 3PAR Online Import adds following enhancements:

Host Persona 13 and 7 are supported for HP-UX 11iv3.HP 3PAR OS 3.1.3 supports Host Persona 15 for Windows 2008, Windows 2008 R2, andWindows 2012. Host with these operating systems must be converted to Host Persona 15 fromHost Persona 2 after the array is upgraded to HP 3PAR OS 3.1.3. This can be completed withthe host online and active.For a comprehensive list of supported host operating systems, see HP Storage Single Point ofConnectivity Knowledge (SPOCK) website at http://www.hp.com/storage/spock .

Enhanced Thermal ShutdownHP 3PAR OS 3.1.3 release is enhanced to shut down an entire system or a single node whenoperating thermal limits are reached.

System ShutdownThe system is shutdown when TOC quorum loss is pending for having to spin down too manydrives for over-temperature conditions. The system shutdown includes spin down of all the drivesand shutdown of the nodes. The nodes, drives, and drive enclosures are not powered off as a part


of the shutdown. As with previous releases, an individual disk is spun down when it reaches itsthermal operating limit.

Node ShutdownA single node is shut down when one of the thermal sensors within the node reports a criticalcondition. This feature is available on HP StoreServ 7xxx Storage and HP StoreServ 10xxx Storagesystems.

System Turn onOn HP StoreServ 7xxx Storage and HP StoreServ 10xxx Storage systems, after a thermal shutdownthe systems are brought up automatically when the ambient temperature stays below system turnon temperature for 30 minutes. For all other systems, the current procedure for manually turningon a system is applicable.Alternatively, when a single node is shut down for thermal reasons, the node is held downindefinitely and manual intervention is required.

Options for HP 3PAR OS Software UpgradesWith the release of HP 3PAR OS 3.1.3 and SP 4.2, HP 3PAR StoreServ 7000 customers now havetwo options for upgrading HP 3PAR OS software.

The following error might occur in HP 3PAR OS versions earlier than3.1.3:

The startao command ensuresthat the aomover log file is created.

80249

When startao is executed, the file logging process (LOGFILEMGR)checks the status of the log file /var/log/tpd/aomover. However,

This avoids early exit of thestartao command.

since startao never explicitly creates the aomover log file, on the veryfirst execution of startao the aomover log file does not exist. WhenLOGFILEMGR process notices that the log file does not exist, it writesan error message to the aomover log file and to the task detail, creates/var/log/tpd/aomover, and returns an error status to startaowhich causes startao to exit early. The time when startao exitsmight vary depending on the time when LOGFILEMGR notices that theaomover log file does not exist. As LOGFILEMGR process ensures thatthe aomover log file is created, every subsequent startao worksnormally. Only the first execution of startao encounters this issue.

With HP 3PAR OS 3.1.3, this is resolved. It ensures that /var/log/tpd/aomover exists at the beginning of startao.The aomover log file is currently not used to report the status ofstartao and so it will be always empty. The status of the startaocommand is reported via the task manager, or directly to the commandline.

If a StoreServ is subsequently downgraded to an earlier release suchas 3.1.2, the 3.1.3 filesystem is moved to an alternate boot path onthe local node drive while the primary path is installed with the targetversion. This allows the StoreServ to be reverted to the 3.1.3 release,if desired. Because this alternate filesystem is visible to the 3.1.2monitoring software, the checkhealth warnings (Filesystem is over80% full) and service alerts (Free node disk space) are triggered.

The maximum number of task IDs is increased.With the increased number of VVs, VLUNs and LDs; the output of showvv, showvlun, and showldcommands is displayed in chunks. That is, if the total number of objects printed is 8 K or larger(for showvv, showld, and showvlun), the output is in the form of chunks.

This means:

From one chunk to the next, the columns can be wider, if the names or values are wider.

If the output is sorted, it is sorted within each chunk. This means that the VV zzzz, may appearat the end of the first chunk but not at the end of the last chunk.

The total lines will remain the same.This is the same as the command setclienv histstatnum. For more information, see thecommand setclienv -h.An option -sortcol is added to some CLI commands. This option provides better reportingcapabilities. With this option, you can get SR historical data sorted by any data column.

If begin time is not provided then the time at which the report beginsdepends on the sample category option (-hires, -hourly, -daily) specified.

For hires, the default begin time is 12 hours ago (-btsecs -12h).

For hourly, the default begin time is 7 days ago (-btsecs -7d).

For daily, the default begin time is 90 days ago (-btsecs -90d).

If begin time and sample category are not specified then the time at whichthe report begins is 12 hours ago and the default sample category is hires.

SSD Wear Level Indicator

Capacity(GB)HP part #SSD Model 3PAR

1920762770-003DOPE1920S5xnNMRI

SSD drives have a limited write-life. This means that you can only write to SSD drives a set numberof times before they wear out. The writes for SSD drive DOPE1920S5xnNMRI is allotted one DWPD(Drive Writes Per Day) over five years, allowing a total of 1,825 writes. A PE cycle (Program Erase)is when a drive has completed a write on the entire drive. For example, a 1TB SSD drive will haveto have 1TB of data written to it before a single PE cycle is consumed. The factory tests all drivesprior to shipment which consumes some of the write cycles. The counter should drop from 100%to 99% once 1% of the life has been used. The current algorithm drops 1% on the first PE cycle. Thiswill be corrected in the next release of the drive firmware.
