Using ULTRIX Error Logs
The system records events and errors in ULTRIX error logs.
The memory error logs and the error and status register error
logs may be used to troubleshoot intermittent problems.
The ULTRIX error logs are not the same as the test error logs
that appear when you use the erl command. The test error log
is a record of errors reported by tests run in console mode.
The following sections describe ULTRIX error log formats and
error log items that are useful for troubleshooting.
Examining Error Logs
You must be running ULTRIX to examine error logs. At the
ULTRIX prompt, type /etc/uerf -R | more and press Return. A
full display of error log, with the newest error logs first, appears
on the monitor.
Further information about the uerf command is available in the
ULTRIX man facility. Type man uerf and press Return.
Error Log Format
The first part of each error log describes the type of error and
system conditions in effect when the error occurred. The first
part is the same for all error logs, regardless of the event type.
The second part of each log provides specific information about
the error and its location. In the second part, the information
available for troubleshooting varies according to the event type.
