We have a number of T5120 SPARC servers where the ILOM works fine for months, years - and then suddenly all the ILOM settings just get wiped out and disappear. We are not aware of any power outages that may be affecting the servers. I had one in my cubicle that I was still setting up, and overnight the ILOM settings disappeared while it was running over night. Does any one have any information on this annoying problem?
The T5120 system documentation is here:
I did a quick speed-read of the Service Manual.
There is a coin cell battery inside the system that supposedly is only for time-of-day maintenance
(see page 114 in that documant)
A far stretch, but maybe other settings are also maintained by that battery?
Perhaps others might respond as well.
I would think that if the server is continually powered up, the ILOM settings would remain, regardless of the battery - as I expected the one in my cubicle to do. Perhaps not. I'll check that documentation you listed - thanks.
Update: checking on the most recent system where this happened, on 25 JAN there was a PS0 fault, but on 10 FEB the ILOM was successfully accessed. No power outages in the logs since then and the ILOM was most recently accessed today when the ILOM settings were completely re-inputted because they were missing. The sensor for the battery (I assume) indicates good voltage unless there is some other battery that is not indicated in the sensor settings. So, the ILOM shows no power outages or faults since the last time the ILOM was accessed.

Actually I do know it isn't the cleaning staff because they are only here during the day. This is a secure military facility and they aren't able to get in at night. But anyway, this has happened a number of times and we can't see why ILOM settings are disappearing without power outages occurring. These systems are spread all over the USA so it isn't a local issue either.
