2.9. Managing LUN Snapshots
2.9.2 Listing LUN Snapshots
To list snapshots for the specified LUN, use the vstorage-iscsi snapshot-list command. For example, for LUN 1 on
target iqn.2014-04.com.vstorage:test1:
# vstorage-iscsi snapshot-list -t iqn.2014-04.com.vstorage:stor4 -l 1

In the output above, the asterisk in the column C indicates the current snapshot, while the column PARENT_UUID
shows snapshot dependency or history.
2.9.3 Switching Between LUN Snapshots
To switch to the specified LUN snapshot, use the vstorage-iscsi snapshot-switch command. For example:
# vstorage-iscsi snapshot-switch -u a1f54314-bc06-40c6-a587-965feb9d85bb
After you switch to a snapshot, the current LUN image will be removed.
Note: You can only switch between snapshots, if the LUN is offline.
2.9.4 Viewing LUN Snapshot Information
To view information about the specified snapshot, use the vstorage-iscsi snapshot-info command. For example:
# vstorage-iscsi snapshot-info -u 9c98b442-7482-4fd0-9c45-9259374ca84e
Target: iqn.2014-04.com.vstorage:stor4
