    Andrew,

    Have you resolved this problem?

    Some things to try:
    1) ADSM-L@VM.MARIST.EDU - tsm mailing list
    2) With a 3584 you should have rmtX devices (atape) not
            mtX devices (TSM). Did you upgrade your atape software
            when you upgraded AIX?
            2.1) Check atape software.
            2.2) Delete mt devices
            2.3) Delete rmt devices
            2.4) Run cfgmgr.
    3) Check TSM paths. In a SAN environment, the same
            tape drive will not always be the same rmt device
            on the different machines.
    4) The smc device is not needed on the StorageAgent - you
            do not need to worry about that.

    Fred

    Thanks Simon.

    I actually did do that. I did an

    "rmdev -Rdl fsdcsi1"

    Which deleted the four drives attached to the fiber device and the fiber
    device.

    Here is the wierd thing. The first drive in the library (3584)is NOT
    zoned
    to this node but four other drives (out of 8) are. I am under the
    impression that the library communicates over the same fiber line as the
    first tape drive (the first tape drive in the library which again is not
    connected to the node having the issues).

    When this used to work before the AIX upgrade (although I am not 100%
    the
    upgrade broke it but it seems timely), we used a Storage Agent to
    restore
    the data. Now, we can't seem to use the Storage Agent because it can't
    see
    the library. Our current work around has been to disable the Storage
    Agent
    and perform backups over the network rather then directly from tape
    using
    the Storage Manager (much slower).

    What am I missing?

    I would probably start by deleting your tape drives - completely: rmdev
    -d
    -
    and associated devices, and re-defining them.

Well I think I found the problem.
It appears that the TSM client, which uses a Storage Agent for Lan Free
backups does not have the library defined.
Here some output from our dev box:
[root ] /dev >>lsdev -Cc tape
rmt0 Available 4Y-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt1 Available 4Y-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt2 Available 4Y-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt3 Available 4Y-08-01 IBM 3580 Ultrium Tape Drive (FCP)
Here is the outupt from a lab box from which we can successfully restore
the same exact files to:
# lsdev -Cc tape
rmt0 Available 47-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt1 Available 47-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt2 Available 47-08-01 IBM 3580 Ultrium Tape Drive (FCP)
rmt3 Available 47-08-01 IBM 3580 Ultrium Tape Drive (FCP)
smc0 Available 47-08-01 IBM 3584 Library Medium Changer (FCP)
As you can see I do not have smc0 defined or available on the top TSM
client.
when I run cfgmgr, I am getting:
