Minimizing Updates
Stay aware of the latest software updates for your operating system and applications.
Weigh the risks of updating versus the need for the changes. If you update the
software, it may be harder to restore your system after a failure. On the other hand,
you should update software for fixes that you require.
Using a Methodology
Following a set of procedures when using your server can help prevent problems, or
make your troubleshooting easier if problems do occur.
•
Use uniform naming conventions for your servers, such as names that denote
server location. Uniform naming conventions help when you try to remember
often overlooked details that can hold the key to resolving a crisis.
•
Use unique IDs or names for your devices. You can reduce the risk of
components competing for the same resource if you have a list. Use the server
setup utility to check for conflicts.
•
Make a habit of using the HP tools and resources, your software, and third-party
product resources to keep abreast of potential problems. You may be able to
avoid problems by noting the problems of others.
•
Have a reliable back-up plan. Schedule backups based on the needs of your
server. If data is changed frequently, frequent backups are required. Maintain a
library of backups based on your information-restoring needs. Test your backups
periodically to be sure that your data is correctly stored.
•
Have a plan of action before the server fails. For example, decide what action to
take if any of the following fails:
— Mirror
— SCSI
board
— Network interface controller (NIC) board
•
Check hard disk space periodically. It is recommended that hard drives have a
minimum of 15 percent free space.
