Initiating replication manually

SnapDrive initiates SnapMirror replication automatically when a Snapshot copy is created, but you can also initiate SnapMirror replication manually.

Before you begin

Because SnapDrive automatically initiates SnapMirror replication once a Snapshot copy for a LUN on a SnapMirror source volume has been created, to initiate replication after a Snapshot copy has been created, you need either to manually create a Snapshot copy or to set up a schedule for automatic Snapshot copy creation.

Note: Manual replication is not monitored by SnapDrive so you will not know if replication succeeded.

Steps

Perform the following actions to select the LUN that you want to replicate:
1. In the left MMC pane, select the instance of SnapDrive you want to manage.
2. Double-click Disks.
In the right MMC panel, select the LUN that you want to replicate.
Click Action (from the menu choices at the top of MMC window).
Select Update Mirror from the drop-down menu.
Note: The Update Mirror option is not available if no live mirror copies are configured.

Result

The Update Mirror operation is initiated and a rolling Snapshot copy of the LUN is created. After the Snapshot copy has been created on the mirrored source volume, SnapDrive automatically updates the mirrored destination volume.
