You can change the synchronization settings and warning thresholds that the mirror consistency group on the local storage system uses when data is initially synchronized or when data is re-synchronized during asynchronous mirroring operations.

About this task

Changing the synchronization settings affects the synchronization operations of all mirrored pairs within the mirror consistency group.

Steps

Select Storage > Asynchronous Mirroring.
Select the Mirror Consistency Groups tab.

The Mirrored Consistency Group table appears and displays all the mirror consistency groups associated with the storage system.
Select the mirror consistency group that you want to edit, and then select More > Edit Settings.

The system displays the Edit Settings dialog box.

Edit the synchronization and alert settings as appropriate, and then click Save.

Field details

Field	Description
Synchronize the mirrored pairs…	Specify whether you want to synchronize the mirrored pairs on the remote storage system either manually or automatically. Manually – Select this option to manually synchronize the mirrored pairs on the remote storage system. Automatically, every – Select this option to automatically synchronize the mirrored pairs on the remote storage system by specifying the time interval from the beginning of the previous update to the beginning of the next update. The default interval is 10 minutes.
Alert me…	If you set the synchronization method to occur automatically, set the following alerts: Synchronization – Set the length of time after which SANtricity System Manager sends an alert that synchronization has not completed. Remote recovery point – Set a time limit after which SANtricity System Manager sends an alert indicating that the recovery point data on the remote storage system is older than your defined time limit. Define the time limit from the end of the previous update. Reserved capacity threshold – Define a reserved capacity amount at which SANtricity System Manager sends an alert that you are nearing the reserved capacity threshold. Define the threshold by percentage of the capacity remaining.

Description

Synchronize the mirrored pairs…

Specify whether you want to synchronize the mirrored pairs on the remote storage system either manually or automatically.

Manually – Select this option to manually synchronize the mirrored pairs on the remote storage system.
Automatically, every – Select this option to automatically synchronize the mirrored pairs on the remote storage system by specifying the time interval from the beginning of the previous update to the beginning of the next update. The default interval is 10 minutes.

Alert me…

If you set the synchronization method to occur automatically, set the following alerts:

Synchronization – Set the length of time after which SANtricity System Manager sends an alert that synchronization has not completed.
Remote recovery point – Set a time limit after which SANtricity System Manager sends an alert indicating that the recovery point data on the remote storage system is older than your defined time limit. Define the time limit from the end of the previous update.
Reserved capacity threshold – Define a reserved capacity amount at which SANtricity System Manager sends an alert that you are nearing the reserved capacity threshold. Define the threshold by percentage of the capacity remaining.

Results

SANtricity System Manager changes the synchronization settings for every mirrored pair in the mirror consistency group.
