Using Error Logs
The system records events and errors in the ULTRIX error logs.
Use the memory error, error and status register, and system
overheat error logs to troubleshoot intermittent problems.
Note:
The ULTRIX error logs are not the same as the test error logs
that appear when you use the erl console command. The test error log
is a record of errors reported by tests run in console mode.
The following paragraphs describe ULTRIX error log formats
and error log parts useful in troubleshooting.
Examining Error Logs
You must be in ULTRIX to examine error logs. At the ULTRIX
prompt, type /etc/uerf -R | more and press Return. A full
display of error log entries appears on the monitor.
The first part of each error log describes the type of error and
system conditions in effect when the error occurred. The last
part of each log provides specific information about the error
and its location.
The first part of all error logs is similar to this:
