Folks,

We received the correct command from IBM to recover specific files
from a mksysb tape:

#tctl -f /dev/rmt13 rewind
#restore -s4 -xqvdf /dev/rmt13 /home/oracle

All is fine.

The reason we were having problems with the mksysb tape
was that it was not bootable.
We tried to boot from CD and then access the mksysb but it
appears that the former admin used a different release of
the OS that we do not have here on site.
We were told to forget about the mksysb and just use the level
of the operating system that was already on the system.

Thanks for all your help!

Sorry...

We are using an LTO1 drive and are running AIX5.2

We have already tried the following(found on the web)
which didn't work

To recover specific files from a backup made with mksysb, try 
$ tctl fsf 3 
$ tar xvf /dev/rmt0.1 ./your/file/name 

Complained about the blocksize

and

$ tctl fsf 3 
$ restore -xvf /dev/rmt0.1 ./your/file/name 

Said the tape was not in backup format

Thanks!

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

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!
