Deconfiguring a tape library deletes the library as a storage target and also disables the software communication between the MediaAgent and the device.
The de-configure operation will fail in the following situations:
If there are jobs currently running in the library. If necessary, wait for the jobs to complete or kill the jobs in the library.
If media is mounted in the drives. If media is mounted, Unload the Media, before de-configuring the library.
From the navigation pane, go to Storage >Tape.
The Tape page appears.
For the tape_storage for which you want to deconfigure the library, click the Actions button and click Deconfigure.
The Confirm delete prompt appears.
Click Yes to confirm the deletion.
