Troubleshooting
The first step in problem-solving is establishing whether the problem lies with the cartridge, the
drive, the host server and its connections, or with the way the system is being operated.
Most modern SCSI host bus adapters locate and display attached devices when the system is
booting up. On Windows systems, if you swap or connect a product when your system is
running, you will need to reboot the system. IA32 systems also usually need to be rebooted.
UNIX systems may have pluggable drivers, which allow drives to be attached to a running
system and detected without rebooting.
If the device is not detected on boot up, there is probably a problem with the physical
hardware: cables, termination, connections, power or the host bus adapter itself. If the device
is displayed during boot up but cannot be found in the operating system, this is more likely to
be a software problem.
• If you encounter a problem during installation and need further clarification, refer to
“Problems encountered during installation” below.
• If a problem arises during testing after you have installed the drive, refer to the symptom-
based section “Testing after installation” on page 41.
Many users can use HP Library & Tape Tools to help them diagnose problems.
Problems encountered during installation
Unpacking
The SCSI cable shipped with the drive is not correct
It is unclear which SCSI ID to use
Description Further information
Some parts appear to be missing or
damaged.
Contact your vendor if any parts need replacing.
Description Further information
The SCSI cable shipped with the drive does
not plug into the SCSI host adapter of the
server.
The cable provided will connect to the majority of
systems. If a different cable is required, refer to the
www.hp.com/go/connect web site.
Description Further information
It is uncertain which ID numbers are
available.
Use HP Library & Tape Tools (see page 37) to provide
information on your current SCSI settings.
The HP StorageWorks DAT autoloader has its SCSI ID
set to 5 by default. This should be left unchanged
unless this number is already in use. Full instructions
on how to change the SCSI ID are given on page 11.
