CHAPTER 5: Troubleshooting your Autoloader

Overview

Caution

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.

This chapter describes various troubleshooting and diagnostic tools available for use with the autoloader.

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.

Safety guidelines

Warning

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.

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.

Understanding POST

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.
