Ran a backup last night and both the SYS vol and User vol's went
offline. I'm assuming the backup software caused the dismount. Not
sure though. Any tips on troubleshooting what happened? The NWAGENT
software (CA) doesn't give me anything helpful other that sorry can't
find the volume...this occured about 10% into the backup.

Also there were lots of other miscellaneous complaints but I'm certain
they were related to the fact the volumes were dismounted.
