Guidelines for creating a clone of a qtree SnapMirror destination volume

When using the vol clone create command to create a clone of a qtree SnapMirror destination volume, you need to consider the status of any qtree SnapMirror transfers for that volume.

You can check the status of SnapMirror transfers by using the snapmirror status -l command.
The following table describes the different scenarios possible, when creating a clone of a qtree SnapMirror destination volume:
If the status of qtree SnapMirror transfers for a specific volume is... Then, for the creation of a clone of the qtree SnapMirror destination...
Idle The clone will be writable.
Note: It is recommended that you create a clone of a qtree SnapMirror destination, when the status is idle.
Active You can specify a Snapshot copy that is older than any of the Snapshot copies being used for transfers. In this case, the clone will be writable.
If you do not specify a Snapshot copy for the creation, the clone will be read-only.
For a read-only clone created when a SnapMirror transfer is active for the volume, the SnapMirror relationship is active for the clone. Therefore, for the clone, you need to quiesce the SnapMirror transfer and break the SnapMirror relationship. This would make the clone writable.
Note: The original SnapMirror transfer or relationship need not be modified. You only need to change the status of the clone to make it writable.
Note: If you use the snapmirror quiesce or snapmirror break command on a writable clone, then the system displays an error message and proceeds without effect.
