HP EVA Storage Replication Adapter Software for VMware vCenter SRM Administrator Guide

3. Data Replication Group information, including vdisk member information is discovered.
4. For each replicated vdisk found on the protected array, HP P6000 EVA SRA Software version
5.0 gathers the following information:
• Remote array ID
• Remote vdisk name
• Local presentation information
• Host the LUN is presented to locally
• ID assigned to host
5. HP P6000 EVA SRA Software version 5.0 returns this information to SRM.
6. SRM correlates LUNs with datastores in order to determine which virtual machines can be con-
figured for DR failover.

Failover testing
HP P6000 EVA SRA Software version 5.0 provides status information, enables replication I/O when
needed, monitors synchronization status, and performs P6000/EVA operations for nondisruptive
testing of SRM failover recovery plans. SRM uses the information gathered during the discovery process
to create snapshots of remote vdisks. See Figure 3. After testing verifies the vdisks snapshots can be
recovered after failure of the local array (via a recovery plan), SRM uses HP P6000 EVA SRA Software
version 5.0 to unpresent and delete the snapshots. Using HP P6000 Business Copy Software, HP
P6000 EVA SRA Software version 5.0 creates snapshots during recovery plan testing.
