Dump device Problem

[suvy12]

I configured /dev/vg00/lvdump as a dump device in HP-UX 11iv3 server by editing /etc/fstab file.

After some time i remove the line from /etc/fstab and run command crashconf -ar but crashconf commnd output still showing size assigned to the dump device(/dev/vg00/lvdump).

How can it be removed from crashconf output.

Hope server reboot not required for that.

Below is the output

Dump compressed:    ON

Dump Parallel:    ON

Try adding the entry for that LV back into /etc/fstab.  Check the crashconf output and see if the LV name shows again.

If it does then run 'crashconf -d' and specify the name of that LV to delete it.  If it is deleted successfully then remove it from /etc/fstab again.

Hi patric,

Actually i removed that LV after removing the entry from /etc/fstab file.

Now accoding to you i recreate that LV with the same name and size and made entry in /etc/fstab also but now i get the below error

# crashconf -a
/dev/vg00/lvdump: warning: duplicate device
#
#
# crashconf -d lvdump /dev/vg00
lvdump: error: can't find device
/dev/vg00: error: can't find device

Opps my mistake it is working

#crashconf -d /dev/vg00/lvdump

it deletes the device entry from crashconf.

Thnx
