Creating an off-host replica database

Figure 5-2 shows an example where the primary database volumes to be backed

up, dbase_vol and dbase_logs, are configured on disks attached to

controllers c1 and c2, and the snapshots are to be created on disks attached to

controllers c3 and c4. There is no requirement for the OHP host to have access

to the disks that contain the primary database volumes.

Note: If the database is configured on volumes in a cluster-shareable disk group,

it is assumed that the primary host for the database is the master node for the

cluster. If the primary host is not also the master node, all VxVM operations on

shared disk groups must be performed on the master node.
