Troubleshooting and Diagnostics
131000ux/1900ux/2300ux and 3800ux/7100ux Optical Jukebox Service Manual
Host computer system does not
recognize the jukebox or the drives
■ Ensure the jukebox is not in an error
or failed state. If so, troubleshoot the
error before continuing.
■ Ensure the jukebox is connected and
powered on. The jukebox must be
on when booting the host computer
for the jukebox to be recognized.
■ If the jukebox is the last device on
the SCSI bus, check that it has been
terminated and that the maximum
cable length has not been
exceeded.
■ Check SCSI ID assignments and
resolve any conflicts.
■ Ensure you are connected to the
correct SCSI bus type. UDO
jukeboxes are LVDS devices.
■ If using a narrow (8-bit) HBA, make
sure that all addresses are in the
range 0 through 7.
■ For Windows operating systems, use
the device manager to rediscover
the jukebox.
■ For HP-UX, use ioscan to verify
that the HBA and attached devices
are claimed.
■ For other operating systems, refer to
the system administrators guide for
diagnosing missing peripherals.
■ Check that the application software
is compatible with the jukebox.
■ Check that the device is present on
the system using HP StorageWorks
Library & Tape Tools, available from
http://www.hp.com / support/tape
tools .
■ Power cycle the jukebox and power
down the host. Wait until the
jukebox completes its power cycle
before powering up the host.
■
Connection
Other SCSI devices no longer work
when the jukebox is installed
■ Check SCSI ID assignments and
resolve any conflicts.
■ Ensure that the SCSI ID for the HBA
is different from that of the jukebox.
■ Check for proper SCSI cabling and
termination.
■ Ensure the maximum cable length
for the bus has not been exceeded
(12 meters for LVDS and 3 meters
for SE).
