PDFs
You can change the synchronization priority and resynchronization policy that the mirrored pair uses to complete the resynchronization operation after a communication interruption.
You can edit the synchronization settings for a mirrored pair only on the storage array that contains the primary volume.
-
Select .
-
Select the mirrored pair that you want to edit, and then select .
The system displays the View/Edit Settings dialog box.
-
Use the slider bar to edit the synchronization priority.
The synchronization priority determines how much of the system resources are used to complete the resynchronization operation after a communication interruption as compared to service I/O requests.
More about synchronization rates
There are five synchronization priority rates:
-
Lowest
-
Low
-
Medium
-
High
-
Highest If the synchronization priority is set to the lowest rate, I/O activity is prioritized, and the resynchronization operation takes longer. If the synchronization priority is set to the highest rate, the resynchronization operation is prioritized, but I/O activity for the storage array might be affected.

Edit the resynchronization policy as appropriate.
You can resynchronize the mirrored pairs on the remote storage array either manually or automatically.
-
Manual (the recommended option) — Select this option to require synchronization to be manually resumed after communication is restored to a mirrored pair. This option provides the best opportunity for recovering data.
-
Automatic — Select this option to start resynchronization automatically after communication is restored to a mirrored pair.
