Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)

To permanently restore a LUN from a SnapMirror Synchronous destination and make it independent, the protection relationship must be completely removed. This process requires two distinct steps. First, the snapmirror delete command is executed on the destination cluster. This action severs the relationship and converts the destination volume to a read/write state, making the LUN accessible for I/O. Second, the snapmirror release command is run to remove the corresponding relationship metadata from the source cluster. Both steps are necessary to fully decommission the relationship and allow the destination LUN to operate as a standalone entity. While the standard temporary failover command is snapmirror break, it is not an option here.

A. Resync the relationship: Resyncing is used to re-establish protection after a relationship has been broken; it does not restore service from the destination.

D. Initialize the relationship: Initialization is the process of creating a new relationship and performing the baseline data transfer, not restoring from an existing one.

1. NetApp ONTAP 9.10.1 Documentation

"ONTAP commands":

snapmirror delete: "The snapmirror delete command deletes a SnapMirror relationship. The destination volume is not deleted and becomes a regular read/write volume." This confirms that deleting the relationship makes the destination LUN usable.

snapmirror release: "The snapmirror release command releases a SnapMirror relationship. This command is typically used after the snapmirror delete command has been used on the destination cluster to delete a SnapMirror relationship." This confirms release is the subsequent cleanup step.

2. NetApp ONTAP 9.10.1 Documentation

"Data protection guide":

Section: Deleting a SnapMirror relationship: "You must delete the SnapMirror relationship from the destination SVM

and then release the relationship from the source SVM." This section explicitly outlines the two required commands (delete and release) to permanently remove a relationship.
