Hope someone can help me with this:
I was doing a selective full backup of one user filesystem with ADSM.
 It's a large
filesystem so the backup runs a long time, stopping periodically to
migrate data from
the disk backuppool to the tape backuppool.  The tapes are in a DLT
library, with only
1 drive.

I failed with the following errors/messages but I can't figure out how
I had 2 mount requests at the same time.

The mount limit for my 2 DLT libraries is 1 each.
messages:

And while I am at it.... does anyone know where they document all the
weird extra
error codes that sometimes come with the very generic ANR9999 messages
??

I also have HSM running and the HSM tape pool is in the other
library.... but this looks
like it might be involved in the issue.

Thanks for any help
