SnapSAN S3000/S5000 Snapshot User Guide
The snapshot cyclic creation operation cannot be executed for the same base-volume
consecutively. To repeat snapshot cyclic creation, close the Snapshot Cyclic Creation screen
and then re-open it to execute the operation.
If the snapshot creation target volume is in the released state, executing the snapshot cyclic
creation operation places it in the active state.
A snapshot is created for the next oldest generation except for the linked SVs when
snapshots have been created in all the SVs and the oldest SV has been linked with LV.
Clicking the [Cancel] button from the Processing dialog suspends cyclic snapshot creation
and redisplays the Snapshot Management screen. If snapshot deletion is performed but
snapshot creation is not performed, the target snapshot state becomes invalid.
Changing Base-Volume Access Mode
Change access mode of a base-volume to R/W Permit. Execute only when access mode of a
base-volume cannot be returned to R/W Permit from the host.
Display the Base-volume Access Mode Change screen using one of the following procedures.
• Select a base-volume from the base-volume unit list in the information list display
area. Then, from the menu bar of the snapshot management screen, select [Operation]
[Snapshot Operation] [Base-volume Access Mode Change].
• Select a base-volume from the base-volume unit list in the information list display
area. Then, right-click on the mouse and select [Base-volume Access Mode Change].
Selected Volume List
This part of the screen displays a list of information about the base-volume selected from the
base-volume unit list in the information list display area.
If "Unexecutable" is shown in the [Execution Result] field, the volume does not meet the
execution conditions and therefore cannot be selected.
If there is any unexecutable volume, refer to the [Unexecutable Information] and take one of
the following actions.
