    Given the fact that 1/4 SLR tapes are not manufactured any more, would
    it be possible to adapt and substitute a the SLR with a LTO type tape
    unit in a single box 170 AS/400, (No expansion unit) with V5R3M0 ?

    If so, which model would you recommend to substitute a SLR 6382 tape
    unit and where to find it ?

    I guess that we may need a SCSI adapter.

    ¿ Any experience ?

    Technically though it is not officially supported, I know several people who have successfully replaced the internal QIC tape drive with an LT03 tape drive.

    The problem is, you must also remove the CD drive, and saw the sheet metal in between those two bays, to "fit" the LT03 tape drive in there ...

    Then, the trick is, the system will still recognize it as a QIC tape drive, but if you just insert an LT03 tape, and format it with *DEVTYPE, it should "just work" and you can do GO SAVE 21, full saves, and even IPL and restore from it.

    Hope that helps ...

    Thanks, we've got a brand new QIC SLR 30/60GB 6384 in order to replace
    the defective old QIC 4/8 6382 tape unit. No need to saw nor remove the
    CD drive, and given the amount of disk, it is sufficient to contain the
    21 option in one volume instead of 3 cartridges in the old format. One
    problem, was to find the tapes, the other: I am waiting for someone to
    replace the tape unit. I suppose that it is not a very difficult task,
    but I dare to be playing with the guts of that old machine given the
    fact that IBM declined a year ago to continue it's maintenance service
    for such an old hardware.

    Thanks again.
