A client is testing TSM on NW6.5 SP2 in a cluster. It works well, but if
the cluster fails over in the middle of a backup, and the volume being
backed up is dismounted, and then mounted by the other cluster node, then
DSMC.NLM locks up on the failed server, and you cannot exit it.

If you try to force DSMC.NLM to unload during a backup it hard abends the
server. Is there anyway I can failover during a backup and be able to
unload DSMC through the cluster fail script? Or manually unload DSMC after
the event?
