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.
