Dod I ask someting very difficult?
This is a discussion on Please correct/provide help- Mirrored PPs - Aix ; On a mirrored VG workvg ( mirrored on 6 disk 3 of each on a separate ESS) 1 | 2 3 | 4 5 | 6 vpath1, 3, and 5 on one ESS and vpath2, 4 and 6 on differnt ...
On a mirrored VG workvg ( mirrored on 6 disk 3 of each on a separate
ESS)
1 | 2
3 | 4
5 | 6
vpath1, 3, and 5 on one ESS and vpath2, 4 and 6 on differnt ESS
In this miiroed around 11 PPs are mirrored on vpath2 and vpath6 of
the only one LV expanding/ using all 6 disks.
ALL othe PPs are mirrored correctly between ESSs.
I am thinking of following
Check stale PPs
unmirrorvg -c 1 workvg vpath1 vpath3 vpath5
Will this unmirror PPs from vpath2 or vpath6 leaving clean one copy
only on 2 4 and 6?
mirrorvg -c 2 workvg
Will this take care of all PPs copy from 2 4 6 to 1 3 5?
syncvg -v workvg
Set quorum to 1 later
Please let me know if any step is missing or correct or let me know
the alternative.
Thank you very much

Just a shot in dark. No garantees expressed or implied.
Do: unmirrorvg -c 1 but don specify the vpath and see what results.
After this find, the ESS with the smallest number of PP and migratepv all
PP's to disks on the other ESS (ie.1,3,5 to 2,4,6 or vice versa) and then
mirror the vg back to the empty disks
