Here is something that might help do mksysbs to the same drive without
moving the media drawer each time. This has worked fine for us. It can be
adapted for multiple LPAR's
For the local machine:
DEVICE=/dev/rmt0
mksysb -i $DEVICE
for the machines that DO NOT have the media drawer:
mkfifo /tmp/pipefile
mksysb -i /tmp/pipefile &
sleep 120
dd if=/tmp/pipefile | rsh <remote lpar w/ media drawer> dd of=/dev/rmt0
obs=1024
rm /tmp/pipefile
HTH,
Darryl

I don't know much about LPAR yet, (got a course next week), so forgive me if
I'm being stupid...
For a very crude answer, you could always physically move the tape drive.
Or even buy an extra one, if it's something basic like a DLT drive. You
might look into hiring one for a short time. (I assume the problem is not
the tape drive as such; rather the adapter card it's connected to.)
You could set up NIM. Of course, that's quite a bit of trouble so if you're
planning to do the SP Attach soon it might not be worth it.
There have been some posts about building mksysb images on remote tape
drives and/or from a mksysb to disk. You could do something like that,
accepting that you may have to do some messing around when you come to
restore if the tape drive is in the wrong LPAR. You may need to invest a
little time in searching the archives.
