I recently asked this question and someone answered it, but when I logged in the question does not show up...
I left the office for a few days and returned to find the AS/400 shutdown. I thought there may have been a power loss to the building due to storms. I re-IPL-ed the system and it remained running for about 3 days, when I entered the office to find it shutdown again. I restarted it, and it seems that this has happened every few days again. Prior to late June the system has been very reliable and never operated in this manner. It did loose power a few times due to storms over the last 6 months, but prior to late June 2009, it always IPLed (slower of course due to power loss and system recovery) and operated correctly afterwards. At no time has a shutdown command been entered from any terminal/console to shut the machine down when these unscheduled shutdowns have occurred from June 25 2009 or so onward.
I've used the WRKSYSSTS command to display DASD/ASP and only 10.95% of 77300 is used, so the system should not be shutting down due to DASD thresholds/limits being exceeded.
I've looked at QHST logs and I can find when the machine has shutdown (and someone answered my question, have tried to link to the answer when signed on and the question/answer no longer display or are found). I will have to review these logs in more detail. I did write down a bunch of Q files that were in use when the system shutdown abnormally, there are approximately 50-60 files listed. I'll review the QHST log and try to get the MSGID #'s and list them.
I have a notebook computer running also in the office (and connected via TC/IP-Ethernet to the AS/400 and it has communicated without problems), and there was a momentary power surge or drop, or loss of power, the lights in the office did not flicker, and due to new notebook and new battery, the notebook would have been able to run until the battery needed recharging (2.5 hours if power was off that long). So no visible evidence of a power outage, even if only for milliseconds.
When the AS/400 has shutdown I have not been present or if in the building or office I have not observed the display at the time the AS/400 shutdown/went silent. When IPLing each time afterward, no error messages are generated. When looking at the front panel display the 01 BN (automatic IPL selected) displays when the machine is silent (machine plugged into power source, but not running, or machine running) or running, and shows no error codes when silent after shutting down without command entry to instructing machine to do so.
Could it be power supply in AS/400 requiring replacement? Machine is RAID-5 configured, loss of DASD or DASD beginning to fail in mirrored config? The last two shutdowns occurred, and machine is configured to show last user signon data, it shows me (QSECOFR) last signon on 7/1/2009 at time xx:xx:xx. Machine shutdown on July 4, so I would think THAT should be the last signon data, not July 1. Even if each QHST log/system logs are full, system should (OS/400) just generate a new log sequentiallly numbered.
Any similar experiences in the past in any shop out there? Any assistance, ideas much appreciated in advance
