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.
