Running ADSM on NT 4.0 with Qualstar TLS-4440 tape changer system.
The Changer and the two Exabyte Mammoth 8900 drives are all installed on
the same scsi bus (running off Adaptec AHA-7800).

The client can back up to a pool on disk but not can't backup directly to
tape, nor will ADSM migrate to tape. When the diskpool fills up and it
should start migrating to tape, the client gets a message that says
"Waiting for Off-line media" then a few seconds later the client gets a
"Mount Error".

I did Label some tapes in ADSM and the tape changer/drives worked fine (or
at least gave no error messages).

I have a 3GB hard drive with one diskpool and one tapepool of the devtype
8mmtape that I created from the example in the ADSM Getting Started
pamphlet. The DISKPOOL is set to migrate to the tapepool (I tried the
lower/upper limits at 70/90 and 0/0, neither worked).

Has anyone had a situation similar or have advice?

Thank you,
