HP StorageWorks MSL2024 Tape Library getting started guide (AH559-96001, March 2007)

Planning the parallel SCSI
configuration: parallel SCSI
7a
Slide the Library onto the rails. Secure the front bezel to
the rack using a #2 Phillips screwdriver placed through
the small holes in the mounting bracket to tighten the
captive screws on each side of the Library.
If the Library has only one parallel SCSI drive and is
the only parallel SCSI device connected to the host
computer, or you will put each drive on its own parallel
SCSI bus, skip this step.
If you are unfamiliar with configuring parallel SCSI
devices, read the parallel SCSI configuration
information in the User and Service Guide on the
documentation CD.
Follow these general guidelines when planning the
parallel SCSI configuration:
• The Ultrium 960 and 920 are Ultra320 parallel SCSI
devices. Only put one Ultrium 960 or 920 tape drive
on an Ultra320 bus. Putting an Ultrium 960 or 920
tape drive on a lower performance bus will degrade
its performance. Do not connect an Ultrium 960 or
920 drive to an SE SCSI bus because it will seriously
degrade performance.
• The Ultrium 448 is an Ultra160 SCSI device. Up to
two Ultrium 448 tape drives can be placed on an
Ultra160 or Ultra 2 bus. The Ultrium 448 drives are
compatible with a single-ended SCSI bus, but their
performance will be degraded.
• Avoid putting the Library on the same SCSI bus as
a disk drive or SE device.
• The default SCSI ID of the bottom drive is 4. The
default SCSI ID of the top half-height drive is 5.

Using the screws for your rack type, and a #3 Phillips
screwdriver, secure one rail to each side of the rack. Secure
the front and the back of each rail to the rack. The front of
the rails is straight and the back is angled, as shown.
