I have a disk-based pool of 92GB with the MAXSIZEthreshold set to 700M and
the next storage pool set to my tapepool which has this parameter set to
NO LIMIT.  I have a few NetWare clients that have files that >700M.
Everytime the backup hits these files on the node, the backup stops with
an ANS1312E error in the error log file.

Here's what the Messages manual says about this error:

ANS1312E Server media mount not possible.
Explanation: Server media mount not possible. The server timed out
waiting for a mount of an offline volume.
System Action: File skipped.
User Response: Retry later when server volumes can be mounted.

Given this error, I ran a selective backup of one of these files.  During
this backup, the node sends about 1.3MB and then fails with the error.
And, during this time, I check to make sure the tapepool is not being
utilized and no tapes are mounted.  The server attempts no media mount and
there are no actlog entries that indicate a problem.

Has someone seen this?  How can this be fixed?

Here're the system details:

TSM v3.7.4.0
AIX 4.3.2
Atape.6.0.4.0
Library: 3575 with 6 3570C drives

Here's the node opt file:
