Running TSM 5.1.5.4 on IBM H70 AIX 5.1.3 with Scalar100 (4 LTO1 drives).
Client is W2K 5.1.5.  TSM Server has fiber GIG connection to a Cisco 4506
and the client has a copper Intel GIG NIC into the same switch. Networking
in not a bottleneck. Everything on the server looks good. The robot pulls
the tape, mounts it in the drive but the client doesn't think it's there.
Manually tried to start backup from client and it fails 3 out of 4 times.
Some times the backup starts and 1/2 way thru fails with the same errors.

02/04/2004 21:07:17 ANS1512E Scheduled event 'NIGHTLY_NOTES_2' failed.
Return code = 12.
