Well, there's still a bit of work to do. I have to deal with the
failing load source disk. I have two good spare drives, so this is
what I attempted:

1. Install spare drive and IPL to DST
2. Format the spare drive
3. Copy the load source disk data to the spare
4. Power down
5. Remove the failing load source drive, and install the spare in it's place
6. Attempt to IPL

#6 fails. The machine is stuck in an endless loop of dumping main
storage and re-IPLing. Crap. Time to wipe the disks and restore again.

You know that with what you have just learned, you could make some big
bucks as a consultant when some old 620/720 et al kicks the bucket
right? i have done at least 3 or 4 reloads on machines that the owners
foolishly let 2 drives die on the raid...

Best regards and keep tinkering!

Well, that worked. Sort of. Here's what happened today:

I restored all seven disks from the original image files I created
when I first got the system, before it was powered up. B M IPL failed
with a 27419022. Tried a D M IPL - stays at C6004508 for almost an
hour. Get into DST, there are only 6 drives showing. Where did the
missing drive go?
Shut down, pulled the drive that wasn't showing up. Over to the PC it
goes. There isn't anything wrong with it. Back into the 720 it goes,
for another attempt.
D M IPL goes OK, not stuck at C6004508. Get into DST, all drives are
present. Time for the real test - can I do a B M IPL, like I did when
I first go the thing?
The B M IPL completed OK, I can sign in to DST with '22222222'.
Time to hack the DST profile again so I can get my QSECOFR back....

Such is the life of the one who is low-level hacking. Be glad you are
doing it for sport. System restores on those old machines take a long
time. Nothing like starting RAID5 on a 14x141Gb set... 12Hs watching
percentiles go by.
If you make it work, i would back up the system keys (dsplickey
*print) just in case it breaks again.

Best of Luck!

I_BASE_01 V5R3M0 seems to work - it IPLs from the CD-ROM drive just
fine. But the severe weather is going to prevent me from doing
anything interesting with it right now.

BTW, this is V5R3

   So presumably depends on whether "v5r3 +" intends to imply "v5r3
and
beyond" as I suspect probably is the case.

I recall seeing an IBM FTP site that has some I_BASE_01 CD's.... I
do not remember what version of OS you have, but maybe worth a look
