EXABYTE EXB8200 on 280R

Hi There,

I'm trying to install an old Exabyte EXB-8200 drive on a 280R to rescue
some archived data from an IBM RS6000 AIX machine. I have tried both a
terminated and unterminated Wide -> Narrow (Centronics) cable to connect
the drive to the machine. Both produce the following output on a SCSI probe
:

ok {0} probe-scsi-all
/pci@8,600000/SUNW,qlc@4
LiD HA LUN --- Port WWN --- ----- Disk description -----
 0 0 0 500000e0104239d1 FUJITSU MAP3735F SUN72G 0601
 1 1 0 500000e010407b11 FUJITSU MAP3735F SUN72G 0601

/pci@8,700000/scsi@6,1
Target 5
  Unit 0 Removable Tape EXABYTE EXB-8200 2618

  Unit 1 Removable Tape EXABYTE EXB-8200 2618

  Unit 2 Removable Tape EXABYTE EXB-8200 2618

  Unit 3 Removable Tape EXABYTE EXB-8200 2618

  Unit 4 Removable Tape EXABYTE EXB-8200 2618

  Unit 5 Removable Tape EXABYTE EXB-8200 2618

  Unit 6 Removable Tape EXABYTE EXB-8200 2618

  Unit 7 Removable Tape EXABYTE EXB-8200 2618

/pci@8,700000/scsi@6
Target 6
  Unit 0 Removable Read Only device TOSHIBA DVD-ROM SD-M14011009

...which seems err, odd.

Has anyone seen similar issues? The drive worked quite happily on a Linux
box (though refused to read the tapes from AIX, though would write and read
its own). Seems like there may be some issue with Linux tape drivers and
these AIX tapes.

Now getting earache from business end who can't understand why data they've
neglected for <n> years on a decommissioned system can't be recovered in
minutes... (Technical) suggestions welcome :)
