    Folks,

    Basically the DB guys said it was OK to just use whatever OS configuration
    was present on the system and that they could restore the databases
    themselves

    So, we just changed the name and IP of the system to the system that was
    on the mksysb

    Unfortunately, one of the DB admins needs his home directory restored
    which is on the mksysb

    How does one restore specific files from a mksysb?

    Thanks!

    Dave,

            I've seen this before and for the life of me I don't remember
    what "0>" means. I do know this is a firmware prompt, so naturally the
    next question would be: Why are we getting a firmware prompt?

            Before we explore this matter further, let's get some facts
    straight:

            (1) What is the type/model/series of the machine? Is this a
    server or workstation? I ask this because some models do not support
    booting from tape.

            (2) What is the current version of the AIX operating system
    on the machine?

            (3) What is the version of the AIX operating system on the
    purported mksysb tape?

            (4) What LED code is displayed when you get the "0>" prompt?
    First, does your machine have an LED display?

            (5) Is the system a standalone or rack-mounted system?

            (6) Is the machine an IBM RS/6000 machine or a pSeries
    machine (p630 on up)?

            Please advise.

            Best wishes,

    Folks,

    The system that we are trying to restore has an installed OS.

    We are now attempting to boot into the SMS menu and change
    the bootlist to disk

    BTW...The error we got on the mksysb boot was

    0>

    on the screen

    Good morning, Dave,

            It's unclear as to whether you are trying to boot from a mksysb
    TAPE or not as already appropriately addressed by Martin in an earlier
    response to your issue(s).

            If, in fact, you are trying to boot from a mksysb TAPE, AND you
    know this is the correct image for the machine you're trying to recover,
    then we can nip this little problem in the bud by simply changing your
    boot list on the machine. By default, the tape device is not part of the
    boot list. So, the plan is to boot from one of your CD-ROMs and change
    the boot list. Afterwards, we can mount the tape and reboot the system
    from the mksysb TAPE. The procedure that would guide me would look
    something like this:

            (1) Boot from CD-ROM.
            (2) Change boot list.
                    Command: bootlist -m normal rmt0 hdisk0
            (3) Power off machine.
            (4) Insert mksysb tape in tape drive.

            I hope this information helps, and good luck.

            Best wishes,

    Subject: mksysb recovery problems

    Folks,

    We are trying to recover a box from a mksysb.

    We first tried to boot off the mksysb but it failed

    Then we tried to boot off CDROMs then access the
    mksysb but we got an error indicating that the operating
    system was different between the CDROMs and the mksysb
    (we suspect that the former admin used personal CDs to
    create the operating system that do not match the level
    we are using presently)

    Is there anything we can try?

    My boss is pretty hot about this...
    :0(

    Thanks!
