Hi David,

   With regard to the ANR1401 Error, when a TSM volume fills up on an LTO
Generation II drive, the drive does not reset its EOT (end-of-tape) flag.
Subsequently, when a scratch volume is being mounted in the same drive and
TSM tries to write the BOT (beginning-of-tape) information, the drive
returns to the driver (and then TSM) that it is at the EOT (end-of-tape) and
therefore TSM is unabe to write to the tape. In the TSM actlog, all you get
is ANR1401W indicating that volume failed to mount. This is an LTO II drive
microcode problem which is fixed at microcode 37E1 level and above.  The LTO
Generation II drive firmware must be updated to 37E1 level or above.

    I am sure that others on the list will have an answer to your other
issues

Subject: Tape mount failures result in schedule failure

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.
