hardware related causes. However, if the system is booted from CD–ROM, diskette, or
tape, it will be lost if another check occurs. At 4.2 support to analyze the status
information in NV–RAM is included on the Standalone Diagnostics (boot from removable
media).
Error Log Analysis
•
Error Log Analysis is analysis of the AIX Error Log.
•
Error Log Analysis is part of the diagnostic applications and is invoked by selecting a
device from the DIAGNOSTIC SELECTION menu, by using the diag command, or
selecting the Run Error Log Analysis task.
•
Error Log Analysis is only performed when running online diagnostics.
•
Error Log Analysis is NOT performed when running from removable media except for
mounted CD–ROM.
•
Error Log Analysis will only report problems if the errors have reached defined
thresholds. Thresholds can be from 1 to 100 depending upon the error.
•
Permanent errors do not necessarily mean a part should be replaced.
•
Automatic Error Log Analysis (diagela) provides the capability to do error log analysis
whenever a permanent hardware error is logged.
•
The Product Topology Service Aid will log an entry into the error log each time it detects a
new part. This shows ELA that previous errors should not be analyzed. If Product
Topology is not run, then the error log should be cleared manually.
Diagnostic Modes
The Diagnostic Modes consist of Problem Determination Mode and System Verification
Mode. The only difference between the two modes is one performs ELA and the other does
not.
•
Problem Determination Mode will run all tests unless the resource is being used. If a
problem is not found, then Error Log Analysis is performed.
•
In Problem Determination Mode, Error Log Analysis is performed even if a resource is
being used.
•
A screen will always appear informing the user that the resource needs to be freed if a
resource is being used.
•
System Verification Mode does not do ELA. This mode should be run when doing a repair
verification.
•
IPL Control Block Analysis is done in either mode.
It is generally better to run Online Diagnostics versions 2.0 and later from disk than it is to
run Standalone Diagnostics.
