Reactivating the source volume

When the source volume becomes available, you must resynchronize the data from the destination volume to the source volume, update any modifications after the resynchronization operation, and activate the source volume.

  1. Resynchronize the source volume.
  2. Update the source volume.
  3. Reactivate the source volume.
  1. Resynchronizing the source volume
    When the source volume is online, you must resynchronize the data between the destination volume and the source volume to replicate the latest data from the destination volume.
  2. Updating the source volume
    After resynchronizing the source volume, you might want to ensure that all the latest changes are updated on the source volume before activating the source volume.
  3. Reactivating the source volume
    After resynchronizing the data from the destination volume to the source volume, you must activate the source volume by breaking the SnapMirror relationship. You should then resynchronize the destination volume to protect the reactivated source volume.
