I needed help to remove secondary dump device because I need to migrate everything off my hdisk1 to hdisk0, but I have no more space to do so. Then I need help on how to create it again after my work is done.

root@servername:/root -> lsvg -p rootvg
rootvg:
PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
hdisk0            active            546         8           00..00..00..00..08
hdisk1            active            546         536         110..99..109..109..109

root@servername:/root -> lspv -l hdisk1
hdisk1:
LV NAME               LPs     PPs     DISTRIBUTION          MOUNT POINT
lg_dumplv2            10      10      00..10..00..00..00    N/A

1) Close the device by setting the secondary dump target to a special null device:

sysdumpdev -P -s /dev/sysdumpnull

2) Remove it:

rmlv lg_dumplv2

...

3) Recreate it:

mklv -t dump -y lg_dumplv2 rootvg 10 hdisk1

The dump devices don't have (and need) a standard type, so instead of  "-t dump" you can also use "-t sysdump" or whatever you like.

4) Open the new device  by reassigning the secondary dump target to it:

sysdumpdev -P -s /dev/lg_dumplv2
