Are you talking about /var/adm/crash? Or are you talking about application core files?

For crash dumps see savecrash(1M):

hi,

Normally, the crashed process core file goes to the HOME directory of the process executing.

Am not sure that this can be controlled.

good luck

kind regards

Jit is referring to the system crash dump location, not a core file from a single process. The default location is /var/adm/crash and is set in the file:

/etc/rc.config.d/savecrash

The line reads:

SAVECRASH_DIR=/var/adm/crash

Since the vast majority of HP-UX servers use this directory, I would keep this path. Then remove the contents of /var/adm/crash leaving an empty directory. Now pick a new logical volume and add it to /etc/fstab:

/dev/vg00/lvolNEW /var/adm/crash vxfs largefiles,delaylog 0 2

Then after creating a filesystem on the new lvol, use the mount command:

mount /var/adm/crash

Now a system crash will be copied from the dump area to the new lvol at reboot time.

You mean current directory.

>Am not sure that this can be controlled.

On 11.31, see coreadm(1M).
