21 Jun 12 Taking apart a blown up vxvm boot system
Scenario:
vxvm boot system shut down decommissioned. It was left off for over a year. Hardware is needed. System is brought up.
Now you have rootdisk2 part of the boot disk group and to do anything useful you need to clean it up.
Get data:
vxprint -ht -g rootdg
I thought to write this only after I was done. So I don’t have a before state picture.
vxdg -g rootdg rmdisk rootdisk02
Getting rid of the sub disks (BE CAREFUL)
