Connecting to a LUN in a mirrored destination volume

Connect to a LUN on a SnapMirror destination volume when you want to continue to serve data if a LUN on the source volume is inaccessible.

The following requirements must be met before you can connect to a destination volume:

SnapDrive supports the use of FlexClone volumes, which enable you to clone an independent volume from a parent FlexVol volume so that the mirror can remain unbroken.
The LUN on an asynchronous SnapMirror destination must be restored from the most recent SnapDrive-created Snapshot copy containing a valid image of that LUN. The restoration is performed by SnapDrive as part of the LUN connect operation on an active file system or on a SnapMirror destination volume.
Note: The most recent Snapshot copy must be one created by SnapDrive to ensure data consistency. Data ONTAP creates a Snapshot copy that is more recent than the Snapshot copy created by SnapDrive; however, the Data ONTAP Snapshot copy cannot be used by SnapDrive because it is not consistent.

Connect to the mirrored LUN on the SnapMirror destination storage system.
If you want to break the mirror and connect to a SnapMirror destination volume that is online and, in the case of an asynchronous SnapMirror volume, perform a single file SnapRestore operation or rapid LUN restore, click Yes in the Connect Disk dialog box.
Note: Perform this step only if the destination volume is not “broken”. The mirror does not need to be broken if you connect to a LUN inside a Snapshot copy.
