Abstract

This guide provides information to help you avoid future system problems. While

many of the pointers provided are common-sense suggestions, these prevention tasks

are too important to overlook.

This guide is for the person who installs, administers, and troubleshoots servers. HP

assumes you are qualified in the servicing of computer equipment and trained in

recognizing hazards in products with hazardous energy levels.

Most problems occur when something in the server system has been changed. Follow

these tips when making any changes to the server:

•

Back up the system often. Be sure that the backups are not corrupted before

making changes. If the system contains valuable data, have at least two complete

known functional backups of the operating system and data, a copy of the backup

software, and a functional tape drive that can read the backup. Two backups

ensure complete data recovery in the event that something happens to the first

tape or during the first restore attempt.

•

Document the system settings. If the system configuration will be changed, first

obtain a record of the current system configuration settings using the Survey

Utility.

•

Check the HP resources, the software documentation, and third-party product

documentation for information about potential problems. Websites are excellent

places to find this information.

•

If possible, make changes one at a time. This minimizes variables and maintains

a controlled environment.

•

Record the results of each change after it is executed, being sure to include any

error messages or additional information collected.
