Sandra,

The delete dbvol should work on a mirrored volume without failing.  The
contingency if it doesn't would be a database restore.  On a non-mirrored
volume, TSM will check for sufficient space on other volumes and fail the
command if there is not enough space, but that's not what you're doing.

If you plan on running un-mirrored until you add more raw disk to the
system, you can do your del dbvol, then define dbvol of the volume you just
deleted - no need to delete it from the filesystem or reformat it.
