Breaking the Persistent Reserve of a Shared Non-concurrent Volume Group

  1. Special care must be taken when using this method of importing changes of a shared volume group. The system can become corrupted and data loss will occure.
  2. On the system with the online active volume group, break the persistent reserve.
    1. # varyonvg -bu <volume group>
  3. On the system you want to import the changes to, import the volume group but DO NOT activate it.
    1. # importvg -L <volume group> -n <physical volume>
  4. After the import is successful on the online active volume group, reset the persistent reserve.
    1. # varyonvg <volume group>
