We are having the same exact problem except on an MVS server. We are running
3.1.2.0 release of the server and have also opened up a problem and are awaiting
an answer. Please let us know if you get an answer and I will do the same.
Sounds like this is not server specific.

I have a call in to support, but thought maybe someone in the list might
have experienced this and could provide some insight.  I have ADSM 3.1.2.1
running on AIX 4.3.1.  We use a 3494 with 6 3590 tape drives.  Our atldd is
at 3.2.1.0 and Atape is at 4.2.1.0.  ADSM requests the mount of a tape.
MountWait is set for 30 minutes.  The 3494 never mounts the tape, but ADSM
keeps on waiting and never gives up.  I can't find my notes, but I think we
ended up finding a tape in the drive. This happened a couple of weeks ago
when I was restoring some tape volumes the robotics had damaged, and I
bounced ADSM.  It happened 3 times over 2 days, but not on the same tape(s).

Saturday morning I discovered a client backup had been running for 7 hours
because it was waiting on a tape mount.  I bounced ADSM since I couldn't
cancel anything to free it up and took the drive in question (I found it by
using mtlib to query the drives and found the only one that was busy, yet
had nothing mounted in it per ADSM).  This morning I found out that a backup
stgpool that started Saturday afternoon was still running, waiting on a tape
mount.  I don't know if it's coincidental or not, but it's waiting on the
same tape as the client backup was Saturday morning.

Does anyone know why the 3494 doesn't mount the tape, or ADSM doesn't use
the MountWait parameter?
