c3000, fan speed 100%!

hi! i have a problem. today all 6 fans in enclosure increase their speed to 100% and continue keep it.
I read on the internet that the reason may be the absence of OA. Can our OA out of order, or lost link with enclosure?
If i reset OA affect it on the servers?
Can it help me?

Hi, yes, the OA can be reseated safely. (most of the time..).

Check out firmwares as well.

Any problems reported in the OA?

OA reports no problem. If reset OA will help it reduce fan speed?

I would check the firmwares.. are you running a supported set?

This can besides firmware be caused by a blade server having some kind of issues, a blank not installed, obvious room temperature/airflow issues.

problem was in one of servers. As soon as I turn it off, fan speed decrease to 28 percents. just in case I have updated the ilo firmvare on all servers. now it works perfectly.

This is a known issue with ILO firmware 1.81 and is solved from 1.82 on...
So yes please update firmware to 1.82 for all ILO's and at least 2.60 or higher for the OA...
Good luck
