Hola,

I have an R710 that is perpetually complaining of command time out errors on several disks. OMSA storage commands show all disks in OK status, but the alertlog shows multiple:

Severity      : Non-Critical
ID            : 2405
Date and Time : Fri May 22 11:56:58 2015
Category      : Storage Service
Description   : Command timeout on physical disk:  Physical Disk 0:3:6 Controller 1, Connector 0

... on several disks. There have been complains of service degradation, and nothing else in OMSA seems to correlate.
Exported the lsi log, and found multiple instances of:

Anybody have an idea what the cause may be, and how to fix it?
