Important Note
In case of object copies or device mirroring, RMAN will always store the media ID that belongs to the
original tape. RMAN is not aware of object copies. If the original media expired or was exported, it
does not exist in the IDB anymore, but only the COPY. In this case, the Media ID shown by RMAN
may refer to an empty tape or to a tape that contains other backup.
2. Export media
a. A media export, removes the information about the media and its content from the Internal
Data Protector Database. However, its content remains intact.
b. Before been able to export a media, the media protection has to be removed by recycling
the media.
c. The media export has to be done for all media used in the Backup.
Note:
It is not strictly necessary to export the media on the Source cell Manager.
While this step can be done in a data center Consolidation scenario, it
obviously cannot be performed in a Disaster Recovery, when the Source
cell Manager is not available.
3. Make the media available to target cell manager.
In our testing, we used a tape-based library and a disk-based library:
a. Tape Library: The tape or tapes used for the backup need to be inserted in the target
library slots
b. File Library: If a File Library was used for the backups:
i. Create a directory on the target system (our case hpu015) to allocate the file
library files (for example, /dp_jukebox)
ii. Copy/Transfer the file depots from the source system to the target one, under the
new created directory
Note
Exported file library media can only be imported into a Jukebox. This is a
DP limitation
