scsictl on HDS 9580 disks

Hi there

I've a rp7420 running 3 vpars connected to a HDS 9580. Recently I receive some "bogus" EMS errors regarding device "failed". Upon checking the VG, diskinfo, pvdisplay , the reported device is still working properly.
Further checking on Perf View on the failed device indicates there is a high disk response time during the period the disk "faileD"
HDS engineer recommend I change the SCSI queue depth to 4 using scsictl.

As I'm not sure of what's the problem, i cannot be certain if the scsictl command will help.

Anyone has come across such bogus error and how to check what's wrong with it.



If it doesn't work, We'll make it work. If it works, We'll make it work better.
