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

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

Vdisk name

Recovery ESX server HBA ports (WWNs) for post-failover LUN presentation
