Aix Log Io Error
Management Disk Flash Servers Software Tape AIX > Administrator > Systems Management Reviewing AIX unix error log Error and Boot Logs July 2013 | by David Tansley Print AIX provides comprehensive logging of events—some are errors requiring attention

and others are just notifications. For system administrators, tasked to make sure the system is running without major issues, logging provides alerts or apprises them of events as they happen. AIX offers different logs http://www.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.cmds2/errdemon.htm depending on the action and when it occurred. These logs hold information on the boot-up process, console, hardware and system software events. It’s up to the system admin to take action on these events, because once AIX has published the log, its job is done. Logs, Logs, Logs AIX not only offers the errpt but also other error reporting logs. Using the alog command one can list and http://www.ibmsystemsmag.com/aix/administrator/systemsmanagement/error_logs/ pick a log to view: # alog -L boot bosinst nim console cfg mdmplog lvmt lvmcfg dumpsymp When issues arise during the boot-up process, for example, and you’re not at the console, you can review the start-up process messages, particularly the boot and console messages. To list the available logs: alog -o -t For example, to view the console log: alog -o -t console Logging Your Own Entries The standard errpt list hardware or software events in AIX that have occurred. However, you might want a message generated and inserted into errpt after some user interaction, for instance, if a system admin has made a change. This allows the change notification to be visible via errpt. Like the logger command that writes to the system log (messages file), errlogger will write an operator notification entry to the error log. For example, having completed an AIX upgrade, you could post that to the error log, so other users could view it, like so: errlogger "AIX upgrade completed - no errors- test" Working With errpt The first thing AIX admins should do is get event notifications via email. Those errors/warnings will be emailed as well as posted to the errpt log. First, create an email alia

The label of each new entry is checked against the contents of the Error Record Template Repository, and if a match is found, additional information about the system environment or hardware status is added.
