
After encrypted media is recycled using this process, the data is unrecoverable.
Important
Before beginning the recycle process, use your software to take the library off-line
or stop all backup or restore operations to the partition. Attempting to recycle
media while the host is issuing commands to the library through the exporting
drive may cause the backup or restore operation to fail. In addition, the library may
hang and require a restart in order to continue operations.
