how can i remove and rebuild the mirroring for rootvg before applying any patches on the system .
Hi,
this assumes you have hdisk0 and hdisk1 as rootvg mirror and two sysdump devices called lg_dumplv + lg_dumplv2:
to unmirror and 'clone' the root disk to the freed up disk where you can boot from back into the original if anything goes wrong during your patching:
unmirrorvg rootvg hdisk1
migratepv hdisk1 hdisk0
reducevg rootvg hdisk1
bosboot -ad /dev/hdisk0
bootlist -m normal hdisk0
alt_disk_copy -P "all" -B -d hdisk1
and to mirror again:
alt_disk_install -X
extendvg -f rootvg hdisk1
mirrorvg rootvg
migratelv -l lg_dumplv2 hdisk0 hdisk1
bosboot -ad /dev/hdisk0
bosboot -ad /dev/hdisk1
bootlist -m normal hdisk0 hdisk1
alternatively you could remove the second dumpdevice before you unmirror - and recreate it after you mirror again.
Hope that helps
kind regards
