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.
