HP StorageWorks DAT Internal Autoloader Getting Started Guide

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 47.
• If you need to replace your drive, refer to “Replacing your autoloader” on page 52.
Many users can use HP Library & Tape Tools to help them diagnose problems.

Contact your vendor if any parts need replacing.
Description Further information
Additional parts may be required for fitting
the autoloader into the server.
The HP StorageWorks DAT internal autoloader will fit
into most servers without the need for additional
hardware other than that originally shipped with your
system. If additional parts are required or the original
parts have been lost, contact your server vendor. See
“Step 5: Attach mounting hardware” on page 19.
Description Further information
It is uncertain which ID numbers are
available.
Use HP Library & Tape Tools (see page 43) 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.
