Chapter 5 Troubleshooting

• First make sure that the system is configured properly. Most system problems are the result of
incorrect system and SCSI subsystem configurations.
• If it is a network related error, determine if the user has enough memory and hard disk drive
capacity. Run the diagnostics for the network interface cards. Consult with the network
operating system manual.
• If it is a hardware error, follow the instructions to log users off the LAN and down the server.
Boot the Power-on Self Tests (POSTs). If you get an error, look up Error Messages for further
instructions. If the POSTs pass, you can run the HP DiagTools. Besides the POST and HP
NetServer DiagTools diskettes, the standard set of tools recommended for troubleshooting are:
à
àà
à HP NetServer Assistant. HP NetServer Assistant (NSA) is a customizable software toolset
that helps monitor and manage servers over the network from an HP OpenView console.
The NSA software has a server part and a management console, or client, part.
à
àà
à TopTools. HP TopTools provides a set of web-based management tools you can use to
maintain and control your HP NetServers running Microsoft Windows NT, Novell
NetWare/IntranetWare, or SCO UNIX.
• Always change one component—and only one component—at a time.
• Verify the error.
Check for any general problems:
1. Verify all cables and power cords are firmly plugged into the correct receptacles.
2. Verify all components of the system are turned on and properly adjusted.
3. If the server is plugged into a switched multiple-outlet box (power strip), ensure the switch on
the outlet box is turned on.
4. Verify power is available at the outlet by plugging another different device (such as a printer)
into the power outlet and turning it on.
5. Verify the HP NetServer is configured correctly.
6. If the NetServer still does not work, turn it off and remove all external peripherals, except the
monitor and keyboard. Test to see if the NetServer now works.
7. If the server still doesn't work, turn off the monitor, the NetServer, and all external devices. Note
the position of all power cords and power cables before unplugging them. Then:
a. Remove the cover.
b. Verify all accessory boards are firmly seated in their slots.
c. Ensure all disk drive cables are securely connected.
d. Verify switches and jumpers on mass storage devices and boards are properly set (see the
setup instructions in the component document or the manual that comes with the mass
storage device).
8. Replace all power cords and power cables.
9. Turn on the monitor.
10. Turn on the NetServer.
11. Verify the error.
If a problem still exists, check for any distinct problems that may be caused by the hardware or the
software:
1. Simplify the HP NetServer configuration to the minimum required: the monitor, one flexible and
one hard disk drive, and the keyboard.
