Changing the failover/failback setting of a virtual disk may impact which controller presents the disk.
Table 6 identifies the presentation behavior that results when the failover/failback setting for a virtual
disk is c

NOTE:
If the new setting causes the presentation of the virtual disk to move to a new controller, any snapshots
or snapclones associated with the virtual disk will also be moved .
