Hi,

The environment is TSM/StorageAgent/Win2000 5.2.2, IBM 3584 LTO library.


Activity log indicate that session 237 failed to mount a tape volume
293AGHL2 in drive mt3.0.0.3, showing repeated
ANR8779E (Session: 237, Origin: SP02B_STA)
 Unable to open drive mt3.0.0.3, error number=2. (SESSION: 237)

so after 5 minutes got
ANR1401W (Session: 237, Origin: SP02B_STA)
 Mount request denied for volume 293AGHL2 - mount failed. (SESSION: 237)

It then mounted the volume successfully in drive mt6.0.0.3.

3 minutes after that, session 255 started to mount 298AGHL2 in mt6.0.0.3,
resulting in repeated
ANR8779E (Session: 255, Origin: SP18A_STA)
 Unable to open drive mt6.0.0.3, error number=170. (SESSION: 255)

It then mounted the volume successfully in drive mt5.0.0.3.

Is this behavior normal for tape libraries?  It is an indication of some
problem with the drives?  Where can I find the meaning of the error number 2
and 170?

Both tape mounts were requests by scheduled backup and it seems to me as a
result of the tape mount failures, the scheduled got a return code 12 and
showed up as failed.  Is this assessment correct?

Thanks in advance to anyone who can shed some light on this.
