If you have TopTools remote management software installed and configured for use with DiagTools, you can
accomplish any of the above list of tasks remotely.
About Error Messages
A hexadecimal number designates each error message reported by DiagTools; a short note on the type of
error; and a list of one or more steps the user can take in response. When you run a test, it exercises many
aspects of the hardware, so the number of possible error messages exceeds 300. Most of these are
encountered rarely, if ever.
Error codes can be viewed on line from the DiagTools User menu within the advanced series of tests, or you
can refer to Chapter 3 of the
HP NetServer DiagTools Error Reference and User Guide .
Advantages and Limitations of Hardware Diagnostics
Off-line diagnostic software is useful in making sure that hardware has been eliminated as the cause for
possible system problems. Such diagnostic tools can easily be shipped with a server, and they are relatively
easy to use.
However, off-line diagnostic software should be used only by experienced personnel who can take a wider
view of its limitations, which include:
•
Booting the server from the diagnostics diskette
•
No access to operating system error logs, since the OS is not operating at the same time as the
diagnostic tools
•
Limited ability to test only a single component at a time
•
Inability to indicate problems with wrongly configured systems or the network
Event Log Menu
The Event Log menu has information about current and resolved events. The menu provides a list of all
events currently in the log. These may be errors, or normal system events like a system boot.
NOTE You can view system events in the status screen and in the Event Log Report Utility
in NetServer Utilities on Navigator. The details may differ slightly.
1. Select Event Log from the Main Menu.
The first two lines of the log appear on the HP NetServer's front panel display:
****Event Log****
>008^ POWER Unit
2. Use the arrow buttons to see the complete list.
This is a sample event log:
****EventLog****
>008^ POWER Unit
>007^ TempError
>006
CPU Failure
>005 POWER Unit
>004 Volt Error
>003 CPU Failure
