Hello,

We have AIX 5.3 running on brand new p5 520. I find that both
machines after a few days of usage are entering diagnostic mode with
no console attached. [But to hack the diag problem, I do have to
attach the console].
As per the diagnostic tool, I diagonized all resources -and
everything is reported as fine. I did a problem analysis and it
reported the following information:-
-----------------------------
AC Power/coolant failure: 110000AC
....
Scan chrp failure: follow maintenance procedure FSPS04
follow maintenance procedure FSPS06
-----------------------------

I noticed that during a bootup, many a times the system gets stuck
with 110000AC on the LCD panel and one has to preset the reset button
to get past it. I have searched the suer and service manual and the
entire IBM website -and there is no document containing the term
FSPS04/6.
Can someone tell me what the problem could be and how to fix it?
If I have to live with this problem, how does one ensure that on
bootup it does not drop into diagnostic mode?

On the diagnostic menu, I found that option (5) allows me to drop
into single-user mode and from there I changed the run level (init 5).
The kernel loaded but I got quite a few messages:-
execve: cannot load a 64-bit program ..
when starting some of the daemons.

This problem did not show up before getting into diagnostic mode -and
we do have bos.mp64 and bos.64bit installed at the same time.


Any hints on how to get the machines fully functional (between
reboots)?

thanks
