Use the Medium Complete operation to set a tape to read-only.
This is useful when:
- You have encountered errors reading from or writing to the tape
- You have written particular archives to the tape and do not wish to use it anymore
- The tape is almost full
Note: Media Manager automatically completes tapes when the remaining free space drops below 2.5 percent of the native capacity.
A completed tape can no longer be used for new archive tasks, although it is still available for retrieve tasks.
Performing a Medium Complete operation sets the state of the tape to Complete in Removable Storage. Removable Storage Manager uses the same icon for the Complete state as for the Disabled state: 
. You can tell the difference between the two states by looking at the State column in Removable Storage Manager or the Partition State column in the Media Manager Media pane.
