Failover testing
HP EVA Virtualization Adapter provides information and performs 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 2). After testing verifies the vdisks snapshots can be
recovered after failure of the local array (via a recovery plan), SRM uses HP StorageWorks EVA
Virtualization Adapter to unpresent and delete the snapshots. HP Business Copy EVA is used to create
snapshots during recovery plan testing.
NOTE:
For Failover, the ESX LVM settings must be set to default for Snapshot (default is disallow) and
resignature (default is allow).

Failover recovery
During recovery, SRM executes a recovery plan. When SRM reaches the Prepare Storage step in the
recovery plan, it provides the LUN information needed for failover to HP EVA Virtualization Adapter.
The information includes:
• Recovery site storage array ID
• Vdisk name
• Recovery ESX server HBA ports (WWNs) for post-failover LUN presentation
