Using /var for logs is one of the most common mistakes when configuring an HACMP cluster. This is a very long story that dates back to at least HACMP V4 and it is very sad that IBM did not manage to get around that problem for years now. So it is the cluster admin's responsibility to not do that. Search this group for questions related to /var getting full and how to avoid that.

You move the cluster logs positions with cluster commands only. Read the cllog manpage. There is also a CSPOC panel if you prefer SMIT.

To take the pressure from the /var filesystem you could remove (i.e. mv and/or rm) unused logs (the rolling logs have a trailing number with 1 being the youngest and 7 the oldest log). Some logs are being held open by cluster processes. You must not move them but you could blank them with

Code:

# > big.log

or if you prefer the non-AIX long version

Code:

# cat /dev/null > big.log

This way you can prevent your server from dying a painfull and slow death. If you think you still need the log's content just copy it to any place you like before blanking it.

NAME

       ds.log - Availability Suite data services log file

DESCRIPTION

       The  /var/adm/ds.log file contains the Availability Suite data services command log. The administration commands log activities to the file
       in the format:

	 date time product: message

       Note that when the size of the log file exceeds 10 Mbytes, ds.log is renamed  /var/adm/ds.log.bak  and a new /var/adm/ds.log file  is  cre-
       ated.

       The ds.log fields are:

       date

	   The	date format is mmm nn, where mmm  is  the local three-character abbreviation for the month and nn is the day of the month on which
	   the event occurred.

       time

	   The time of the event, in hh:mm:ss format.

       product

	   A product code that identifies which component of the data services produced the event. The code is separated  from	the  message  that
	   follows by a colon (:) and a space.

       message

	   A  message  that  can extend over  more  than  one  line describing the event that occurred. The second or following lines are not pre-
	   fixed by  the  date, time, and product code strings.

EXAMPLES

       The example below shows sample ds.log file content:

	 Jan 25 05:26:17 ii: iiboot suspend cluster tag <none>
	 Jan 25 05:32:02 ii: iiboot resume cluster tag <none>
	 Jan 25 05:32:04 sv: svboot: resume /dev/vx/rdsk/bigmaster
	 Jan 25 05:32:04 sv: svboot: resume /dev/vx/rdsk/bigshadow
