I have two 2450's that are exhibiting the same random voltage fluctuation on the backplane +12v sensor. Both set at 11.562v nominally, both dip at times to 11.500 and set off the low voltage warning threshold. They never stay there for long, so within seconds usually they're back up to 11.562 again.

 

We have OMSA installed on both of these, both reporting into ITA. I'm attempting to get these servers to quiet down a bit, as sometimes they flux back and forth enough in a short amount of time to spam a hundred emails or so.

 

On both of the machines, I have gone into OMSA and change the low voltage warning threshold for backplane +12v to 11.480. I do this and the alerts stop and the emails stop. The problem is that any time the server is rebooted, OMSA goes back to its original default value of 11.500, which necessitates my going back in and setting the 11.480 again.

 

Shouldn't OMSA keep threshold setting changes I make? Is there a way I can force it to keep them?

 

Any help is appreciated.
