HP EVA Storage Replication Adapter Software for VMware vCenter SRM Administrator Guide

Remote vdisks are members of HP P6000 EVA storage systems and HP P6000/EVA data replication
groups, and are replicated between protected and recovery HP P6000 EVA storage systems and HP
P6000/EVAs using HP P6000 Continuous Access Software.
Disk array discovery sequence
Once the array manager has been added and configured from within VMware SRM, SRM calls the
adapter to discover the arrays configured for with the SRA. SRM periodically calls the SRA to refresh
array information.
The array discovery sequence is:
1. SRM sends a request to HP P6000 for available arrays to HP P6000 EVA SRA Software version
5.0.
2. HP P6000 EVA SRA Software version 5.0 connects to HP P6000 Command View Software
servers and requests array controller port information (WWN).
3. HP P6000 EVA SRA Software version 5.0 returns the results to SRM.
SRA discovers arrays configured in the Storage administrator portal, and replica peer arrays if
a Data Replication Group (DR Group) is configured between them (see Figure 1).

LUN discovery sequence
Once SRM has discovered the available arrays and an array pair has been enabled, SRM calls the
SRA to discover all replicated devices and consistency groups between the pair and uses the information
to calculate datastore groups that are to be used in protection groups.
The LUN discovery sequence is:
1. SRM sends a request for replicated LUNs on a local (protected) array to the HP P6000 EVA SRA
Software version 5.0.
2. HP P6000 EVA SRA Software version 5.0 connects to HP P6000 Command View Software
servers and requests replicated vdisks on the protected array.
