Other Snapshot Commands
These commands are available by right-clicking in different snapshot configuration columns.

Commands are listed from left to right and from top to bottom as shown in the diagram above.

Delete Snapshot Set/Snapshot Container/Snapshot Image: Allows you to manually remove a snapshot element.

Set Name & Comment: This command brings forth an input window with two text boxes that allow you to put a name tag and description for a specific Snapshot Image or Snapshot Set.

Expand Snapshot Container: This command allows you to expand an existing Snapshot Container by joining in another RAID partition/volume.

You can join another RAID partition with the Snapshot Container volume currently in use. Free space can also be acquired by expanding logical drives.
NOTE that once you join a RAID partition into an existing Snapshot Container, you cannot separate them after the expansion.

To expand a Snapshot Container,
Step 1.         Left-click to select a Snapshot Container.

Step 2.         Right-click to display the configuration commands. Left-click on the Expand Snapshot Container command.
Step 3.         A volume selection window will prompt. Use a single click to select a RAID volume with free space, and then select an unused partition.

Step 4.         Click the OK button to complete the process.

As shown below, the added partition will be listed in the Media Extent List.

Fault Recovery Commands: These commands apply only when system faults occur. For some reasons, the snapshot cannot write to disk drives, or fail to read data from Snapshot Containers or Snapshot Sets. Read/write errors could result from drive media errors or the inconsistencies between cached data and data on drive media. The Fault Recovery commands can be used to recover the inconsistencies after media faults or logical drive errors are corrected.  

Configure Snapshot Policy + Space Utilization Threshold: These commands belong to the automated purge management. See here for details.
