power fail ?

[xiayd]

the led on the the power is green, but the console display like this:

Broadcast message from root@sadcora2 (tty) at 15:00:26 ...

rc.powerfail: init has received a SIGPWR signal.
The system is now operating with a power problem.



Broadcast message from root@sadcora2 (tty) at 15:01:26 ...

rc.powerfail: init has received a SIGPWR signal.
The system is now operating with cooling problem.

why ?

 

[kHz]

check the errpt. you probably have a power supply problem.

 

[p5wizard]

Or maybe you've HAD a power supply problem (temporary loss of power on one of your power outlets connected to the two power supplies).

If that was the case, it should also be noted in errpt ("Electrical power resumed" I believe). Then you have to manually edit root's crontab to get rid of the 12 hourly wall message.

[KenCunningham]

We've had a similar problem in the past, and p5wizard's advice was 100%.

 

[jaggerd]

I agree with p5wizard and Ken, we lost our entire 690 on Monday because of a power failure and I had 7 LPARS that I had to get the 12 hour wall out of root's crontab when all of the LPARs came back up and online. Should be the last entry in the crontab if it's not edited on a regular basis.

 

[DukeSSD]

Run advanced diags to sysplanar0 in system verification, if they pass, it was a power failure or a brown out (momentary loss of power that the system registered but did not go down for). Diags will probably say an error was logged but no trouble was found, in which case log a repair, either when you get the option, or using diags, task selection, log a repair action: to sysplanar0. Then edit the wall rc.power from roots cron table.
If you don't log the repair, diag ela will just pick up the errpt entry again at 4am the next morning and you'll get the messages back again.
If diags fail you have a psu out and diags should tell you which one and the location / fru number.

and i run diag, but no trouble was found!


so strange!

If you have a box that can have two power supplies and only one is working, I have seen this type of message, especially when the faulty one was removed for repairs.

you say you run diag, but if you run diag in problem determination after logging a repair action:
2F3E09A4 0215150506 I H sysplanar0 REPAIR ACTION
diag will not find the problem.
run diag, advanced diags, system verification, sysplanar0 and you will see if you still have a problem.

 

[p5wizard]

Please post an "errpt -a" output please. Was anything "fixed" before you (or IBM?) logged the repair action?

What type of server is this btw? I seem to remember some types of server can get into all sorts of trouble re power and cooling if the wrong microcode was applied. E.g. 7026-6M1 microcode on a 7026-6H1.

Perhaps you need to get in touch with IBM support.



HTH,

p5wizard

 

[xiayd]

the server is 7026-6H1, and replaced a power two or three months ago(a IBMer did it)

 

[p5wizard]

Well, I'd suggest you open up a new call with IBM support, perhaps there's something wrong with the replacement part you got.


HTH,

p5wizard

 

[DukeSSD]

Once again, for the hard of hearing:
RUN DIAG, ADVANCED DIAGS, SYSTEM VERIFICATION, SYSPLANAR0 AND YOU WILL SEE IF YOU STILL HAVE A PROBLEM.
