AIX

Hi,

My system has added an entry to the cron:

--> crontab -l
0 00,12 * * * wall%rc.powerfail:2::WARNING!!! The system is now operating with a power problem. This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.

I have had an issue like this in the past but there has always been an errpt associated with it?

can someone help me to identify if there is actually an issue?

another worry I have is my root cron has been over written - anyone know how this can happen?

Thanks in advance

Yup, this happens when the box detect any problem with its 'power supply' and if You do an 'errpt -a -d H' it will display additionnal info on when the problem occured ... well unless it has been cleared by errclear which is also on root cron!
If everything is back to normal, just comment that line ...

well the thing is there is no error report created .....

We did have a power supply in the CEC fail last week which also did not create any error report and we only found out when we moved the redundant PDU to another source.

Do you know of any issues with AIX where these alerts can be left out of the errpt. I have to go to the DR site now to identify the problem at the server level.

system level:

--> instfix -i |grep ML
All filesets for 5.2.0.0_AIX_ML were found.
All filesets for 5200-01_AIX_ML were found.
All filesets for 5200-02_AIX_ML were found.

don't know why you didn't get any error reports, but as you say you had problems with power supply last week, then the system generates this crontab entry, when the problems are solved you have to manually remove the line from crontab

are you 100% sure that no one cleared the errorlog? if thats really the case , and I am sure it's not, run diagnostics over the whole system and open an IBM call if you have an support contract, if not just delete the line and live with it

lol, 100% sure I didnt run the errclear, this has also been removed from the cron entries.

Have run diag's on all system resources with no avail.

Thanks all the same

so you have removed the line from cron and it comes again after a period of time or a reboot?

Yes the entry has been removed, I am going to read some of the system manuals to see if there is a setting I missing.

This is the first time the power alert has come apparent.

I am going to monitor the system closely and investigate at the server tomorrow and identify any power issues
