Figure 1 Discovered Information
.
Disk array discovery sequence
The array discovery sequence is:
1. SRM makes a request to HP EVA Virtualization Adapter for available arrays.
2. HP EVA Virtualization Adapter connects to HP Command View EVA servers and requests array
controller port information (WWN).
3. HP EVA Virtualization Adapter returns the results to SRM.
LUN discovery sequence
The LUN discovery sequence is:
1. SRM makes a request to HP EVA Virtualization Adapter for replicated LUNs on a local (protected)
array.
2. HP EVA Virtualization Adapter connects to HP Command View EVA servers and requests replicated
vdisks on the protected array.
3. HP Command View EVA looks for vdisks that are members of data replication groups.
4. For each replicated vdisk found on the protected array, HP EVA Virtualization Adapter gathers
the following information:
• Remote array ID
• Remote vdisk name
• Local presentation information
• Host the LUN is presented to
• ID assigned to host
5. HP EVA Virtualization Adapter returns this information to SRM.
6. SRM correlates LUNs with datastores.
