Disable snapshot volume

You can disable a snapshot volume or a snapshot volume in a snapshot consistency group when you no longer need it or want to temporarily stop using it.

About this task

Use the Disable option if one of these conditions applies:

You are finished with the snapshot volume or snapshot consistency group snapshot volume for the time being.
You intend to re-create the snapshot volume or snapshot consistency group snapshot volume (that is designated as read-write) at a later time and want to retain the associated reserved capacity so you do not need to create it again.
You want to increase the storage array performance by stopping write activity to a read-write snapshot volume.

If the snapshot volume or snapshot consistency group snapshot volume is designated as read-write, this option also lets you stop any further write activity to its associated reserved capacity volume. If you decide to re-create the snapshot volume or snapshot consistency group snapshot volume, you must choose a snapshot image from the same base volume.

Note: If the snapshot volume or snapshot consistency group snapshot volume is part of an online copy relationship, you cannot perform the Disable option on the volume.

Procedure

Select Storage > Snapshots.
Select the Snapshot Volumes tab.
System Manager displays all the snapshot volumes associated with the storage array.
Select the snapshot volume that you want to disable, and then select Uncommon Tasks > Disable.
Confirm that you want to perform the operation, and then click Disable.

Result

The snapshot volume remains associated with its base volume.
The snapshot volume retains its World Wide Name (WWN).
If read-write, the snapshot volume retains its associated reserved capacity.
The snapshot volume retains any host assignments and access. However, read-write requests fail.
The snapshot volume loses its association with its snapshot image.
