Manage asynchronous mirrored pairs

You can manage a mirrored pair to remove a mirror relationship from a mirror consistency group, increase reserved capacity, and change the alert thresholds for reserved capacity settings.

  • Remove asynchronous mirror relationship
    You remove a mirrored pair to remove the mirror relationship from the primary volume on the local storage array and the secondary volume on the remote storage array.
  • Increase reserved capacity
    You can increase reserved capacity, which is the physically allocated capacity used for any copy service operation on a storage object. For snapshot operations, it is typically 40 percent of the base volume; for asynchronous mirroring operations, it is typically 20 percent of the base volume. Typically, you increase reserved capacity when you receive a warning that the storage object's reserved capacity is becoming full.
  • Change the reserved capacity settings for a mirrored pair volume
    You can change the settings for a mirrored pair volume to adjust the percentage point at which System Manager sends an alert notification when the reserved capacity for a mirrored pair volume is nearing full.
