Chapter 7 Troubleshooting Common Installation Problems The following sections contain general procedures to help you locate installation problems. If you need assistance, it is recommended that you contact your reseller first. If you need to get assistance from Hewlett-Packard, refer to Chapter 8 for information on service and support. WARNING Before removing the cover, always disconnect the power cord and unplug telephone cables. Disconnect telephone cables to reduce shock hazard from telephone ringing voltages. Disconnect the power cord to reduce exposure to high energy levels that may cause burns if parts are short-circuited by metal objects such as tools or jewelry. Troubleshooting Sequence To troubleshoot an installation problem, follow these guidelines: • Make sure that the system is configured properly. Most system problems are the result of incorrect system and SCSI subsystem configurations. Run the EISA Configuration Utility and check all settings in the program. If your NetServer is configured with a disk array, run your DAC configuration utility and check all settings in the program. • If it is a network-related error, determine if the server has enough memory and hard disk drive capacity. Consult your network operating system manual. • Verify that all cables and boards are securely plugged into their appropriate connectors or slots. • Remove all added options and, when troubleshooting, always change one component, and only one component, at a time. If it is a hardware error, perform these steps: 1. Log users off the LAN and power down the server. Remove the NetServer cover. 2. Simplify the HP NetServer configuration to the minimum required: a monitor, one flexible and one hard disk drive, and a keyboard. Remove all third-party options, and reinstall them one at a time, checking the system for the error after each installation. 34

Common Installation Problems
The following sections contain general procedures to help you locate installation
problems.
If you need assistance, it is recommended that you contact your

If you need to get assistance from Hewlett-Packard, refer to
Chapter 8 for information on service and support.
WARNING
Before removing the cover, always disconnect the power cord
and unplug telephone cables.
Disconnect telephone cables to
reduce shock hazard from telephone ringing voltages.
Disconnect the power cord to reduce exposure to high energy
levels that may cause burns if parts are short-circuited by
metal objects such as tools or jewelry.
Troubleshooting Sequence
To troubleshoot an installation problem, follow these guidelines:
•
Make sure that the system is configured properly.
Most system problems
are the result of incorrect system and SCSI subsystem configurations.
Run the EISA Configuration Utility and check all settings in the program.
If your NetServer is configured with a disk array, run your DAC
configuration utility and check all settings in the program.
•
If it is a network-related error, determine if the server has enough memory
and hard disk drive capacity.
Consult your network operating
system manual.
•
Verify that all cables and boards are securely plugged into their
appropriate connectors or slots.
•
Remove all added options and, when troubleshooting, always change one
component, and only one component, at a time.
If it is a hardware error, perform these steps:
1.
Log users off the LAN and power down the server.
Remove the
NetServer cover.
2.
Simplify the HP NetServer configuration to the minimum required: a
monitor, one flexible and one hard disk drive, and a keyboard.
Remove
all third-party options, and reinstall them one at a time, checking
the system for the error after each installation.
