Increase the size of one or both dump devices.

By making lg_dumplv bigger

use extendlv command

HTH,

[khalidaaa]

for example, to increase it by 1G:

chfs -a size=+1G /dev/lg_dumplv

Oh i'm sorry its a dump lv

so it should be by using extendlv

Check out:

http://publib.boulder.ibm.com/infoc.../com.ibm.aix.cmds/doc/aixcmds5/sysdumpdev.htm

Try running
#sysdumpdev -e
while the system is busy for an estimate of how big the dump device should be.

If you ever want to be able to analyse a dump to determine the cause of the problem you should turn on "always allow dump" and "force copy"

Moreover,

The /usr/lib/ras/dumpcheck utility will tell you all you need about your dump devices!

It will:

- Estimate the dump size using sysdumpdev -e
- Find the dump logical volumes and copy directory using sysdumpdev -l
- Estimate the primary and secondary dump devices sizes.
- Estimate the copy directory free space
- Report any errors in the error log file
