How To
Summary
Sometimes, we need to recreate dump device, to change some attributes or relocate dump device to larger disks.
Steps
1. Change the dump pointer,
# sysdumpdev -Pp /dev/sysdumpnull
After that, status of the primary dump device lg_dumplv will be "closed" in output of "lsvg -l rootvg"
# sysdumpdev -Pp /dev/sysdumpnull
After that, status of the primary dump device lg_dumplv will be "closed" in output of "lsvg -l rootvg"
2. Remove the dump logical volume,
# rmlv lg_dumplv
# rmlv lg_dumplv
3. Create a new dump device,
# mklv -y lg_dumplv -t sysdump rootvg #LP hdisk#
# mklv -y lg_dumplv -t sysdump rootvg #LP hdisk#
4. Change the dump pointer to the new dump logical volume,
# sysdumpdev -Pp /dev/lg_dumplv
# sysdumpdev -Pp /dev/lg_dumplv
