We had this problem about two years ago. It was difficult to hunt down the 
cause.

It turned out to be a gbic in a SAN switch that was faulted. The VTL was using 
that gbic. I was able to isolate the faulted gbic by disabling one gbic at a 
time, and run extensive tests until we got the fault. When we did not get the 
fault for 24 hours, we had disabled the faulted gbic.

You should be able to match a SCSI error in daemon.raw against an error in the 
switch log, if your problem is of similar kind as we had. To get the SCSI 
errors in daemon.raw your VTL tape drives need to be configured with "CDI - 
SCSI commands"
