AIX log file and finding

HI,

Where is  AIX system log file located?  We had cluster system and someone executed vgonline on other node. I would like to see how can I verify when it was executed?  Which log file can provide such an information?

Default location is /var/log/

'alog -o -t lvmt' may show what you're looking for, 'alog -L' will give you a list of logs to view.

Use logs to identify issues errlog, alog and syslog

If the VG state was manipulated using standard LVM commands ("varyonvg" etc.) follow benhanson's
suggestion "alog -t lvmt -o".

If you're suspecting some sort of cluster group services activity being responsible for the state change try "alog -t lvmgs -o".

It is possible to issue LVM commands via CSPOC. The log is here: "/var/hacmp/log/cspoc.log".

The names of all cluster logs can be listed using "/usr/es/sbin/cluster/utilities/cllog -s", the
location of a particular log is shown with "/usr/es/sbin/cluster/utilities/cllog -g logfilename"

The main cluster logs are "/var/hacmp/adm/cluster.log" (daemon and script processing) resp. "/var/hacmp/log/clevents" (cluster event processing).

Thank you very much. I can see the history of last few days from the log. How do I check for last few weeks? Thanks in advance

Which log are you talking about?

"alog" always displays the whole log. alogs are of fixed size (lvmt has 200K by default) and use an internal wrap around method.

Some cluster logs are externally rotated, like clstrmgr.debug or clevents.log.

To have a full system log in the future add this to /etc/syslog.conf:

*.debug /var/adm/system.log rotate time 1w size 2m files 6 compress

The name of the file and the rotation parameters are just examples!

Don't forget to "touch /var/adm/system.log" and to recycle syslogd with "refresh -s syslogd".

Attention: The above can/will produce quite a lot of data!
