Nah, because you can still install the LIC from your tape if you define the
alt install device and then install the LIC and OS from there.

John,
When you do that, don't you lose all the DST/SST user-ids?

That's definitely nice about the HMC - being able to change the alt IPL
device quickly and easily - but don't count on it 100%. If you're using
a tape drive that happens to be part of a library then it's ability to
be an alt IPL device becomes a "maybe". It may work. Or not. On our
SCSI 3582 the answer turns out to be not.
For me I've given up on that and will use the LIC CD to get started &
then restore the OS from tape.

Perhaps another reason for an HMC :) You specify the alternative IPL
device on the HMC, and you can tell it an IOP or an IOA, and it has
always found it.
I haven't had a problem on a stand-along system doing a D-mode IPL from
the I_BASE cd, and then bringing up DST and setting my Alternative
Installation Device (close names don't get it mixed up), and using
3580s, 3570s, or 3590s to continue the load from my SAVSYS Tape.

I will give up then. ;)
I think I do remember reading something about the 3580s either not being
supported as Alt IPL or needing some specific setup in order to be used
as Alt IPL. No big deal to use the disc first (have had to do many
times), was just wondering I was missing something!

Resistance is futile. The general rule is pretty much that if your tape
drive qualifies as an external tape drive (according to IBM maintenance)
then it can be an alternate installation device, but, not an alternate
IPL device.
Done carefully, (as you seem to do), then it's not really that big of an
issue, unless of course you do not have copies of your installation CD
offsite with your offsite tapes. I normally have multiple copies of
i5/os laying around. Also, make sure that your offsite base CD is a
somewhat current respin. Some of the latest and greatest models may
have issues with original I Base CD's.

Alt IPL Device (tape)
I've struggled with this one on just about every migration i've done,
and usually just give up and 'D' IPL to the I_BASE_01 CD and then
install from
the Alt Install device from that point forward. On this new 525, even
though i've selected the IOP that the 3580 tape drive is on, it just
keeps cycling through a number of 20031FFF SRC codes and then finally
fails. It seems to be a question of which slot is used for the tape
controller, right?
Does anyone usually hassle through this, or just take the route of
IPLing to the CD and then defining an Alt Install device for the tape
and continuing the install from there? Is there any reason to not IPL
from the CD if you're doing the LIC and OS install from tape? (haven't
seen any ill
effects)
