hmmm... I had an issue with an Exadata X2 some time ago when a user-defined temperature threshold was not giving alerts (later documented in MOS note 1380758.1/bug 13387575 and fixed in 18.104.22.168.0 by the way). At the time I was told that there's no way to see build-in thresholds in cellcli.
As far as the specific error ID goes I don't know what it means, but I'd suggest checking HP iLO documentation in addition to regular Oracle channels.
Excellent suggestion. Luckily, I just happen to have been put in contact with an engineer regarding the case (naturally, I have to re-upload all the diagnostic logs because he has no access to Oracle's SR!)
Having said that, based on previous experience, HP probably don't know or care to know. I get the impression that they resent supporting the Exadata V1 system, presumably because of the litigation, etc.
