AIX

We use HMC to manage two logical partitions. LPARs don't have any problem but HMC's, itself, attention led is on. I am not sure if that's going to affect LPARs, but just wanted to be sure....

Has anyone come across such problem on HMC?
Where can you suggest to look for logs and clear that attention LED on HMC?

I googled that but all comed up as how to clear the log on AIX using HMC.

So, thanks in advance...

Most HMCs are xSeries PCs and have light path diagnostics. You need to look at the associated xSeries maintenance manual or on some outside the cover, some inside, there should be an LED fault panel and a description chart telling you what the lights on the panel mean.

It may have lost a PSU, fan, memory dimm, Etc.

Or you should be able to check the serviceable events logged by the HMC, or maybe there is an entry in the messages file.
