Troubleshooting and Diagnostics
6.1 Introduction
This chapter describes the troubleshooting strategy for Compaq ES40CSLP rackmount systems
along with the power-up and SRM console diagnostics and event log analysis.
6.2 Questions to Consider
Before troubleshooting any system problem, first check the site maintenance log for the
system's service history. Be sure to ask the system manager the following questions:
•
Has the system been used and did it work correctly?
•
Have changes to hardware or updates to firmware or software been made to the system
recently? If so, are the revision numbers compatible for the system? (Refer to the hardware
and operating system release notes).
•
What is the state of the system?
–
If the operating system is down, but you are able to access the SRM console,
use the console environment diagnostic tools, including the power-up display,
SRM diagnostics, and RMC diagnostics.
–
If the operating system has crashed and rebooted, use the CANASTA-NG
(Crash Analysis Troubleshooting Assistant New Generation) with the Compaq
Analyze utility (to translate and interpret error logs), the SRM crash
command, and operating system exercisers.
–
If you are unable to access the SRM console, log into the RMC and issue an
env command and a status command to determine if a hardware failure has
occurred.
6.3 Categories of Problems
System problems can be classified into the following five categories. Using these categories,
you can quickly determine a starting point for diagnosis and eliminate the unlikely sources of
the problem.
1. Power problems Table 6-1
2. No access to console mode Table 6-2
3. Console-reported failures Table 6-3
4. Boot problems Table 6-4
5. Errors reported by the operating system Table 6-5
