MSA1000 - \Device\Scsi\symmpi1, did not respond within the timeout period.

[Jim Staszko]

We've got a MSA1000 setup through a single controller to a Brocade 16 port switch to a HP BL20p blade station with 5 blades. Two blades are running Windows 2003 Server, Enterprise Edition, SP1 clustered with Exchange. The other three are running VM ESX v.2.5.2. We are using Selective Storage, the VM's are setup as Linux and the Windows as Windows. This setup was running fine for a month but ....

At different times during the last three days the VM's and the exchange cluster have had issues with reported time outs trying to get to the disks.
