Use the Increase Snapshot Buffer Size dialog to temporarily increase the snapshot buffer size. To do so, specify the amount of additional space and the volume group for the temporary logical volume. Larger snapshot buffers allow snapshots to be used for longer periods of time. When the snapshot buffer is increased, a temporary logical volume is added. The logical volume is removed when the snapshot is deleted.

To access the Increase Snapshot Buffer Size dialog, navigate to the Snapshot Details portlet, and select Increase Size from the dropdown to the right of Snapshot.

Note: The snapshot buffers can be increased before or after a snapshot is created. If the snapshot buffer has reached 100% the Increase Size option will not be available.

The Increase Snapshot Buffer Size dialog displays.

 

Note: The Increase Size option can be executed a maximum of 64 times to add additional space on different volume groups.

The Increase Snapshot Buffer Size dialog contains the following fields:
