Making an off-host backup of an online database
Figure 3-2 shows an example of two primary database volumes to be backed up,
dbase_vol and dbase_logs, which are configured on disks attached to controllers
c1 and c2, and the snapshots 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.
