The 3 common issues which casue problemw with SCSI tapes:

Incorrect major/minor device numbers (see section on HPDD in the
Maintenance Procedures section of the Operating System Guide).

Incorrect LUN (logical unit number). This seems to work best if
LUN > 3.

Incorrect DMA channel. Verify that the hardware DMA (should be
5 or 6) matches the value in software. This value is stored in

/etc/conf/cf.d/mdevice

on the line that begins with "TAPE" in the far left column. The
value is in the far right column. This value sometimes is delivered
as "-1". If it is incorrect, set it to match hardware  and rebuild
the kernel.
