RE: Alt IPL Device (tape) -- MIDRANGE-L

Hi Pete

On those occasions when I have been unable to get a system to IPL from the D
drive, I have resorted to starting the system from the LIC CD but I make
sure to define the Alt installation device as the tape device BEFORE
installing the LIC. This ensures the LIC is restored from the tape I am
going to recover from. Occasionally I have had search the bus more than once
to find the tape drive.

I have seen systems where the LIC has been installed from CD and then the OS
and other recovery steps have been performed from tape. They didn't always
work so well. From what I could see 5722 999 was missing any PTFs not
contained on the LIC CD causing numerous errors later on. Stands to reason
this will occur unless you are going to re-apply the cume as part of your
recovery.

This also ensures that all the data and settings saved on my tape including
passwords get applied. Where I can I like to include a RTVSYSINF to a
library as part of the backup regime so I have it for recovery purposes if I
need it. If I am stuck with building a system from media then at least I
have the system values and network values somewhere that I can restore them
from.

Regards
Evan Harris

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

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)
