You can change the synchronization priority and resynchronization policy that the mirrored pair uses to complete the resynchronization operation after a communication interruption.
|
|
|
|
.About this task
|
|
|
|
You can edit the synchronization settings for a mirrored pair only on the storage array that contains the primary volume.
|
|
|
|
.Steps
|
|
|
|
. From the left panel, select menu:Mirroring[Synchronous mirroring].
|
|
. Select the mirrored pair that you want to edit, and then select menu:More[Edit settings].
|
|
+
|
|
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
|
|
[%collapsible]
|
|
====
|
|
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.
|
|
|
|
. Select *Save*.
