I have had the same error with our TSM environment.
 The PLM is AIX. And we have 5 * W2K library clients connected to a LTO.
The problem was that when RSM was enabled they were all picking up the
Library changer, which therefore stopped any tapes being mounted.  The
solution was to disable the RSM services and installed the TSM device
driver.  We have had no problems since.

Greetings to all, has anyone encountered this problem before?

Whenever the TSM device driver is loaded the OS gives the following error
and i lose access to the CdRom:

"RSM cannot manage library CdRom0.  It encountered an unspecified error."

If i unload the TSM device driver i regain access to the CdRom. i'm running
TSM Server 5.1.7.0 on a Win2k sp3 OS.

i couldn't find an APAR on this and i have opened a PMR with Tivoli, but i
was wondering if anyone else has seen this problem.

Any help would be greatly appreciated.

Thanks,

john
