Hi ALL:

I have a situation here as follows:

One TSM server 3.7.3
Two RS/6000 H70s at 4.3.3,
Two TSM clients 3.7.3
One shared Magstar 3570 20-cartridge library.

This configuration has been running well for many moons.

We only backup our Oracle dbs + AIX server environments with TSM.

I started getting the "ANS1312E Server media mount not possible" errors  a
few days ago.

Actual dsmerror.log:

01/17/02   03:27:56 ANS1312E Server media mount not possible

01/17/02   03:27:56 ANS1512E Scheduled event 'RS6000H70' failed.  Return
code =
4.
# castor :/ ==>

The dsmsched.log shows the same "ANS1312E Server media mount not possible"
error and the failed return code

The activity log reports:

The automated schedules each give the same error.

When I try and do a manual incremental or selective backups, the same error
occurs (ANS1312E Server media mount not possible).

I can manually do TSM db backups in the Magstar 3570 library with no
problems.

Audit library 3570lib runs without a problem.

I have restarted the TSM server and restarted each of the clients
schedulers to no avail.

I have checked the AIX errpt for any rmt1/2 errors. None reported!

This is a real stumper!!

Anyone have any ideas on this??

ps-I am thinking of upgrading to TSM v4.1 in-order to get TSM Tech support
availability.
