CHAPTER 5: Troubleshooting your Autoloader
Overview
Only use the Diagnostics Commands
when the autoloader is known to be idle
and unavailable to host backup/restore
applications. Use of the Diagnostic
Commands from On-board Remote
Management should not be issued while
the autoloader is being used by host
applications. The autoloader recognizes
when the drive or autoloader are
executing host commands and responds
appropriately to prevent application
failures. A Diagnostic command being
issued between host application
commands may not be recognized
appropriately, resulting in a failed
application, such as a failed
backup/restore job.
Safety guidelines
To avoid bodily injury, do not attempt to
troubleshoot your autoloader problem if:
- Power cords or plugs are damaged
- Liquid has been spilled into your server
- Your autoloader was dropped
- The case was damaged
Instead, unplug your autoloader and
contact a qualified computer technician.
If your autoloader was damaged during
shipment from Gateway, contact
Gateway Customer Care.
Understanding POST
66
This chapter describes various troubleshooting and diagnostic tools available
for use with the autoloader.
Caution
The Power On Self Test (POST) and diagnostic tests are helpful tools for testing
the autoloader's functionality and for troubleshooting errors. With the results
from the POST and diagnostic tests, you can determine how well the autoloader
is working and locate any problems.
The diagnostics section describes the POST and its various tests. This section
also explains how to perform diagnostic tests from the front panel and
On-board Remote Management.
Warning
While troubleshooting your autoloader, follow these safety guidelines:
Never remove a magazine while your autoloader is accessing data or
■
backing up files.
Make sure that you are grounded correctly before working on the
■
autoloader.
Every time you turn on the autoloader, the POST checks all of the autoloader's
basic components. If you experience problems with the autoloader, the POST
is a good method to determine if any major parts are malfunctioning.
