Hi Pawel,

In no particular order, please check with your sysadmins/storage admins about the following :

Queue depth of the LUNs / associated optimal settings for your storage.
Any unsuccessful microcode/firmware upgrade on the FC fabric.
Double check for any combination of any FC/non-FC drives OR any failure of drives/associated raid group rebuild errors.
LUN level i/o statistics and any out of ordinary observations.

-Rajeev
