HP StorageWorks EVA Cluster Extension Software Administrator Guide (T3667-96045, April 2010)

HP Command View EVA uses
HP Command View EVA is used to create vdisks and configure the HP EVA storage system. Using HP
Command View EVA, you can:
• Create Continuous Access EVA DR groups.
• Use Replication Solutions Manager or Command View EVA to view a graphical representation
of a DR group setup.
• Use Replication Solutions Manager or Command View EVA to manually switch source and destin-
ation roles of DR group members.
SSSU considerations
You must use the SSSU to set the access mode of the destination vdisk to read-only. You can also use
SSSU to:
• Create vdisks and DR groups in a convenient automated fashion by using custom scripts.
• Capture your HP EVA storage system configuration setup.
IP network considerations
Because Command View EVA and HP SMI-S are essential resources for EVA Cluster Extension, HP
recommends that you provide reliable network connections for cluster-node-to-management server
communications. HP also recommends that you use the redundant network connections of the
management server for alternative access.
SAN fabric considerations
The management servers use the SAN to communicate with the EVA storage system. Make sure that
the management servers are configured to access both fabrics and EVAs in the Continuous Access
EVA configuration.
