HP EVA Virtualization Adapter then communicates with HP Command View EVA and correlates the

requested vdisks with data replication groups. The adapter fails over each data replication group

associated with the LUN information provided by SRM. HP EVA Virtualization Adapter then obtains

LUN presentation information for each vdisk that has failed over and returns the information to SRM.

The information includes:

• vdisk name

• LUN number assignment to recovery HBA ports

NOTE:

During initial setup, replicated vdisks need to be presented to both the protected and recovery ESX

hosts.

NOTE:

For failover testing, LUN number assignment is the LUN number used by the

snapshot

and not the

parent vdisk.

Communication path

HP EVA Virtualization Adapter provides communications between HP StorageWorks Command View

EVA and SRM. A detailed view of the architecture is shown in Figure 3.

HP EVA Virtualization Adapter processes SRM requests through HP Command View EVA. Once the

information is received by HP EVA Virtualization Adapter, it is passed on to SRM.
