Darren,
 
So looks like it's not a tape drive but something between the drive and
the system.
 
That takes it beyond my domain.  I'll turn the problem over to those
who deal with the SAN/library hardware.
 
Thanks for the help,

So in this case, there's a device between the host and the drives
(possibly a scsi<->fiber bridge).  The device itself has ...2ae9 as a
WWN address.  But it's displaying mulitple LUNs to the host as
separate
drives.  As an example, drive 0 is on lun 6, and drive 1 is on lun 5.

The warning is that the device as a whole disappeared from the fabric,
not that just one particular drive did.  But you can certainly see
which
drives are associated with that device by examining the WWN in the
link
target.
