Create a problem resolution notebook. When problems do occur, keep a log of

the actions you took to resolve them. This could help you solve the same problem

more quickly in the future. System configuration, Survey Utility, and Array

Diagnostic Utility (ADU) printouts, as well as utility diskettes, can also be stored

with the resolution notebook. This information can save a great deal of time in

the future and ensure accuracy, especially when dealing with future part

replacement.

•

Keep an up-to-date network topology map in an accessible location. This will

help in troubleshooting networking problems.

•

If you have a tape drive, maintain a scheduled cleaning program.

•

If you have a tape drive, remember the importance of tape cartridge label

placement. Place the label on the exposed surface of the cartridge so that it

cannot fall off or get lodged inside the tape drive.

•

Consider keeping certain spare parts available onsite. Spare parts to maintain (if

applicable to the server) include SCSI controllers, hot-pluggable redundant

power supplies, hot-pluggable fans, hot-pluggable drives, SCSI cables, network

adapters, Processor Power Modules (PPMs), and perhaps even complete I/O,

media, processor, and memory modules, if the server is modular.

•

Restock spare parts as they are used.

•

Do not clean card edge connectors with erasers; it removes the gold, causes static

discharge, and leaves residue. If connectors have to be cleaned, use isopropyl

alcohol or a special cleaning solution applied with a cotton-tipped swab.

Visually Checking the Server

Periodically, you should look at the following items on the server. A visual check can

prevent many problems.

•

Be sure that systems and racks are not positioned tightly up against walls and that

adequate space exists around them for proper airflow.

•

Move magnetized office items such as magnetized screwdrivers and telephones

with electromagnetic ringers away from the system.
