EMC-RP Replication of LUNs

Login to the EMC Unisphere, login to the storage by selecting the storage either from drop down or from the list.

Go to storage and select LUN



Click on Create > and provide the required Name and Size and select “Thin” for allocating the LUNs as with

Thin provisioning. And click Apply



Similarly create all required LUNs in DR site and Create Journal LUNs in both Production and DR site.

At Production site, we can create Journal LUN for of size 10 GB, but in DR site best practice is to create aJournal of size of 10% of the LUN which we need to replicate.

One from Unisphere: Go to Data Protection > Select Recover Point -> We need to login with local admin toUnisphere to work this



1.1 RecoverPoint Management Application

1.2 Creating the Consistency Group

Select the Consistency Group and > Right click and select the Add group



Create consistency GroupsName # Provide server name (for one server we can have one group, but free to create more as pre requirement)

1ry RPA: Select RPA based on the load balance (Select alternating RPA for each group or best way to balanceload)

Bandwidth Reduction: Medium

Enable dedupe - yes

Protection - Asyn

RPO - select -> System optimized lag

Resource allocation :

Priority : Normal

Bandwidth Limitation : select limited -> select 500 Mbps

Stretch Cluster /VMware SRM -> None

Advance - no change

Make sure allow data transfer if RPA is failed





1.3 Production copy: Configuration for Consistency group

Name# hostname_Prod ( Provide server name _Prod )

Journal comp -> none

Protection :

Enable Recovery port snapshot consolidation:

Do not consolidate for at least 24 hours:

Older than 2days : 5 days

1 weeks to one snapshot -> 0

Select Advance and select Host Os as Windows:



Replica Copies Configuration:

Here we have two options : One for Local copy and Another for Remote Copy . Select Remote copy as we needto replicate

Provide Name and other details similar to the Production copy configuration.

Replication Sets : Select LUNs for replicating

Then click Next and Select DE LUN on which we need to replicate the Data

Journals ( Adding / creating Journals )

If we have already created the Journals , select manually select Journal Volumes ( recommended )



Select the Production site Journal ( generally of 10 GB size, always give LUN name correctly while creating toidentify properly )

Select the DR site Journal ( 10% in size of LUN which we need to replicate)

Click next and see the Summary



Note# if you don‟t want to start the replication immediately , removes the tick mark. And then Apply.





Once done with the Initial copy the Pair status will become “Active” . Then you can s tart using the DR LUNs ( Willallow you to do Image access )
