We have a IBM P730 machine running AIX 7.1 in a properly air cooled server room. Just recently the fans on the unit kicked into overdrive, they are very loud and spinning at max.
Typically this happens when the server first boots then they normalize.
However for some odd reason, they sound like they are spinning at max RPM.
There is no LED amber light on the control panel or anything in the errpt (though I think it was cleared very recently so if there was something in there - it is now gone).
Is there a way from the OS to control the fan speed? There is no LPARs on AIX, we run the OS on bare metal - no virtualization of any kind.
Since this is a D/R site - I have tried to shutdown and startup the machine (I know seems excessive for a UNIX machine); but it did not resolve the issue.
I also tried the "diag" command in AIX and didn't find any issues.
