AIX: Mirroring rootvg

Although the steps to mirror volume groups between HP and AIX are incredibly similar, there are enough differences to send me through hoops if/when I ever have to do that. Therefore, the following checklist:

1. Mirror the logical volumes:
   1. If you don't care what disks the lvs get mirrored to, execute
      
      mirrorvg rootvg
      
      
   2. Otherwise:

      
      for lv in $(lsvg -l rootvg | grep -i open/syncd | \
      	grep -v dumplv | awk '{print $1}')
      do
      	mklvcopy ${lv} 1 ${disk}
      done
      

2. Change the quorum checking if you did not use mirrorvg:
   
   chvg -Q n rootvg
   
   
3. Run bosboot on the new drive to copy boot files to it:
   
   bosboot ${disk}
   
   
4. Update the bootlist with the new drive:
   
   bootlist -m normal hdisk0 hdisk1
   
   
5. Reboot the system to enable the new quorum checking parameter
