Break Mirror on VG00

[Bob Ferro]

I need to either break the mirror on vg00 so I can make 2nd drive bootable. I had a senior moment and forgot to do a pvcreate -B and a mkboot.

Just reverse your mirroring steps.

lvreduce the mirrors off of the "bad" disk.
vgreduce the disk out of the VG.

Now start over.

do
lvreduce -m 1 /dev/vg00/lvol1 and for all the LV that you mirrored of VG00.
once done with the vgdisplay -v you can see that the bad disk should not have any PV allocated and then finally do
vgreduce /dev/vg00 /dev/dsk/<2nd disk you want to remove>
You can then carry with your pvcreate -B etc..
