I would give HP a call and send over the logs.  Take a look at your fibre channel paths on the servers to see if all paths are showing, most likely the controller has failed over but you should look at getting a controller replaced if it's a hardware issue

When you look at your MSA, do you have one or two controllers ?
Don't you see any orange light / LED message on it ?

paulsolov, the warranty expired. I searched for similar cases in the HP forums with various attempted solutions, with varying results.

Stampel, the MSA has 2 controllers.
No colors orange light / display in the Led's

StampelCommented:
The real important message i can see is from your logs is :
"CRITICAL: RAID controller B failed, reason PCIE link recovery failed" + Failover ...
MSA2012fc and MSA2000 have had many problems, i would upgrade firmware first just in case.

Do you still have File I/O error on Oracle RAC ?

Stampel, I/O Errors no longer appear.
But the controller is working like simple configuration.
I will be doing a firmware upgrade, and evenual replacement controller.
Thanks for your comments.
