Prevent Possible Data Corruption
If during the failover procedure you are unable to stop all applications and dismount
all units that are part of a remote copy set, you must reboot hosts prior to failback.
This prevents possible data corruption caused by writing stale data from host cache to
the units after failback.
NOTE: Extreme care must be used when creating and managing remote copy sets on an ATM
link. If these links are overstressed (for example, an excessive number of remote copy sets
created for a given environment), unexpected behavior may result, such as loss of remote copy
sets and link failures.
Command Scripter Communication Failure Error
If the original path to the command console LUN (CCL) is lost, then Command
Scripter will give a communication failure error. You will need to reboot the host to
establish the second path to the CCL.

Failure to Mount File System after Failover or Failback

failback, run fsck on the logical volume and retry the mount.
