Stef, 
We also perform backups to a local 20GB 4mm tape.  Our TSM server is a
B80.  That mksysb tape will not restore to a p650.  From what I have
been told and what I have read, I need to have a set of "install CDs" at
the same OS-ML as the mksysb.  Since I only have "install CDs" for
5200-01 and my mksysb is at 5200-03, I was unable to restore my TSM
server from that mksysb until I found a spare B80 lying around (thank
goodness our DR site vendor had one at that time, but there is no
guarantee they will have one next time, or when we really need it) --
it's a long story as to how this happened.
To be better prepared for every eventuality, I need to find a way to
create "install CDs" at any OS-ML currently in use at our shop.

Aaron (from a different reply),
I have messed around with NIM mksysbs and the mkcd command quite a bit.
Our TSM server is also our NIM server.  Currently, it is only setup with
an NFS exported mountpoint to which other AIX servers perform their
mksysbs.  Using the TSM server alone, I have not yet been able to create
a mksysb CD or DVD image of another system that will boot and restore
that system's rootvg.  Realize, I still need to be able to restore those
client mksysb images to potentially different hardware, as well, so I
still need to have a way to create a bootable "install CD" image of the
existing OS-ML.

I hope that better explains what I am looking for.
Thanks,
Todd

We always backup the TSM server (AIX) on the local tape streamer.  So we
have a bootable mksysb tape that also contains the TSM db backup.
For the other AIX servers we use nim to make backups.  Nim allows you to
make a mksysb to a nim master and stores the mksysb as a file on the nim
master (this is also the TSM server).  The AIX servers can boot from the
nim master over the network and restore the mksysb.
