The problem one is having without a 3270 console is that SAPLdoesn't support SYSC, it needs a 3270. Without a 3270 it is impossible to enter IPL overrides (such as IPLing with the previous version of SYSTEM CONFIG).
A partial solution would be to have several IPL devices, each with their own IPL defaults, to use in case the normal resident has a bad CP nucleus or SYSTEM CONFIG.

You can IPL VM2.4 to the SYSTEM_CONSOLE instead of a 3270 console.
Your SYSTEM_CONSOLE is the HMC's System Messages window ( a sort of
line-mode/tty interface, not full-screen 3270).
At anytime you can force the VM IPL to the SYSTEM_CONSOLE by typing SYSC
in the LOADPARM field of the HMC LOAD window when you trigger the VM
IPL. That overrides your Operator_consoles list.
In SYSTEM CONFIG, Operator_Consoles put SYSTEM_CONSOLE first and you'll
default to IPL-ing to the HMC System Messages window; won't need a 3174
or 3274, but have that limited interface initially.
You could also leave your Operator_consoles statement as-is with
SYSTEM_CONSOLE last; then if VM doesn't find any working 3270's in the
console list it'll use the HMC window.

Subject: IPL Help for old 9672 with VM/ESA 2.4
This is a request to you archaeologist. We have a 9672-A14, running
VM/ESA 2.4, that was originally supposed to die in 2001. It is still
alive, but not feeling too well. The big problem is our 3274 (you read
right) controllers. The 3174s are gone, but we need something when/if
we
have to IPL. We have two 3274s, neither in good shape. IBM has
announced that they will no longer give us a service contract on them,
but the machine will probably have to work after that date.
We are looking for an alternate way to IPL the system. We have been
unable to do so using the hardware management console. Either we don't
know how, or we are too far out of date for it to work. We were told by
an IBM expert, that it does can not work on our system.
It looks like we have to buy an old controller of some kind -- 2074,
3174, 3274, or engage in prayer that the electricity to the 3274s does
not go down. Even without having to power them up, we have had one
instance of a controller stopping working.
I would appreciate any ideas of how to proceed.
I also have a related question. Our SYSTEM CONFIG file contains:
Operator_Consoles 0320 321 9A0 9B0 SYSTEM_CONSole
Emergency_Message_Consoles 0320 321 9A0 9B0 SYSTEM_CONSole
Because of the problems with controllers the operator logged on to 321,
not at IPL time. When we SHUTDOWN the system we had working terminals
on
321 and 9A0, but got no message. When we tried to IPL, the system tried
to use 320, and did not switch to 321 nor to 9A0. Was that because the
controller for 320 and 321 was active?No real problem, because I changed
to console address in the load parameter screen in the HMC, and was able
to proceed, but I am interested in why it didn't work.
As I said, a problem for archaeologists. (My real archaeologist
daughter-in-law was unable to help.)
