We are using Exabyte 8mm drives from Perfect Byte on our HP 9000/360 cluster
servers under HP-UX 6.5. The SCSI device driver included in HP-UX will not
work with tape drives (this is documented in one of the HP manuals). We are
on the third revision of a SCSI driver supplied by Perfect Byte, which is now
working without problems. You'll have to contact the vendor for your 8mm drive
and ask for an HP-UX SCSI driver that supports the drive.

HP support for SCSI is not enthusiastic. Their "monitor" program, for example,
cannot display I/O statistics for drives on SCSI interfaces. Since third party
SCSI drives are the best mass storage solution for HP file servers I hope HP
will improve their SCSI support in future releases of HP-UX.
