RE: B19545092 - errors on system, weird poo

Okay - I definatly waited long enough because the 01 B N was there I
also pulled the power on the network switch which is the only other
thing that 'makes noise' and it was quiet as can be in there There was a
definate "wait" between loosing the login screens and me pulling the
power

This is really freaking me out because I now have two dead systems with
the same errors and Im trying to check everything, even the mundane
(such as pulling the power early) to confirm Im not missing something
simple.

Yes, both of these machines are under IBM warrenty but I was under the
understanding that so long that I have consulted an IBM business
partner, Im aokay to do the install myself and aslong as I use IBM
hardware

Wait for the D100 xxxx (usually D100 0298 if I recall correctly - maybe
it's D600 0298 ?) to disappear from the display, and the 01 B (or 01 A
is that's what you selected) to appear in the display.

You know on a PC with Windows, when you shut the sucker down, if it is
working right, you get a screen saying something about Ok to power your
computer down now & you don't get that screen until after waiting what
seems like unreasonable long time?

Well the 400 similarly has data in cache that is written to hard disk
when you shut the sucker down.  The way I tell with ours is if there is
not another source of noise in the room, you can kind of hear like a
sound of something shutting down, very faint background noise, then I
wait a few minutes more, just in case there is stuff shutting down that
I cannot hear. Perhaps there should be some lights or indicators I
should be looking at, such as indicators on the UPS.

When the screens go blank, that's just system going to restricted state,
there's a lot more time before it has actually shut down.

Do you ever do an IPL power down with immediate restart?
How long does that take?  20 min 30 min?
You have to figure that a one way trip is going to take at least 1/2
that long. That is not actually going all the way down.

Show the IBM hardware guy these e-mails & ask him HOW CAN YOU TELL if
you have waited long enough.
