    Default Problems setting up SCSI tape library

    Hello,

    I'm not quite new to TSM, but far away from being an old hand at it. So I hope to find someone here, who can help me.
    Currently I'm setting up a new TSM server 6.3.3 on SLES 11 SP2. Everything works fine so far, but now I'm stuck with the tape library. It is a SCSI attached Quantum Scalar 50 with 38 slots and 2 HP LTO3 drives.

    I am able to address the library and drives from the OS, the library is /dev/sg2 and the drives are /dev/sg[0|1] or /dev/st[0|1]. Commands like "mtx -f /dev/sg2 status" and "mt -f /dev/st0 status" return reasonable outputs.

    I called the autoconf (-a) and tsmscsi commands in /opt/tivoli/tsm/devices/bin, and I already know about the permissions on the device files for the non-root user the TSM server runs.

    autoconf returns no error, with the following output
    Code:
    tsm01:/opt/tivoli/tsm/devices/bin # ./autoconf

    Anyway I could successfully define the paths in TSM server, with either /dev/sg[0|1|2] or /dev/tsmscsi/lb0 and /dev/tsmscsi/mt[0|1].
    An AUDIT LIBRARY ends after a few seconds with success, but a LABEL LIBVOLUME runs forever (more than a day) without success or error.

    The library worked without problems with the old installation of TSM 5.5 on SLES 9 on the same machine, and there have been no hardware changes, so I can eliminate the possibility that there is an error with the library or the tape drives.

    Does anyone know about the setup of a Scalar 50 SCSI library, or can someone tell me about a HowTo for SCSI libraries? At the moment I don't know what to try anymore.

    Thank you very much
    Bastian

    Hi,
    Try to check library firmware. Autoconf shows: Rev 0033. Check changes from version 0033 to V51.
