Cabling A Shared Scsi Bus With A Tz887 - Compaq TruCluster Server AA-RHGWB-TE Manual

The single-ended SCSI bus may be daisy chained from one single-ended
tape drive to another with BC19J cables, as long as the SCSI bus maximum
length is not exceeded and there are sufficient SCSI IDs available. Ensure
that the tape drive on the end of the bus is terminated with an H8574-A or
H8890-AA terminator.
You can add additional shared SCSI buses with TZ887 tape drives by adding
additional DWZZB-AA/TZ887 combinations.
______________________
Ensure that there is no conflict with tape drive, host bus adapter,
and disk SCSI IDs.
