If the IP address does NOT move there are two things to watch out for:
1) All clients must still reverse resolve the "new" IP address to the same
hostname as before, or the incoming connections from the cluster after the
fail-over will not be recognized as coming from the same NetBackup server.
Although it would be OK to list the hostnames of all the other IP addresses
assigned to the cluster as SERVER entries in the clients' bp.conf files.
2) The routing mentioned before can bite you if any of your clients use a
REQUIRED_INTERFACE directive and as a result cannot route to the new IP
address.

Have fun,
