I've seen this on HP-UX.  We have fibre bridges going to the SCSI drives and 
usually booting the fibre bridge and power cycling the drive takes care of it.  
 In fact just power cycling the drive has taken care of it on a couple of 
occasions.

Hello Paul

I have seen this before, in our case it was usually a problem with the drive 
or SAN-connection. 

I would offline/online the port in the SAN switch and recreate the device 
file for this drive. Then use robtest mount/dismount a tape in the drive.

Regards
Michael
