As i understand it - load the tape in Location 1, inventory. Once this is done, the master should now be aware that the tape is in L1 and do the restore from there and everything should be fine. Please correct me if i am wrong.

Is Location 1 and 2 associated in same or different NBU domain? (Same or different master server?)

If we assume all is under the same master server, does the media server in Location 2 that performed the backup have access to robot in Location 1?
The reason for my question is that the media and backup images are 'owned' by the media server that wrote the backup.
Restore request will be sent to media server that wrote the backup. So, if media server does not have access to robot in Location 1, a 'pending request' will probably be generated for the tape to be moved to Location 2 robot.

If you want another media server in Location 1 to perform the restore, you have 2 choices:

1. Either force all restores for Media server 2 to Media server 1:
   Use Host Properties on Master, General Server -> Media Host Override
2. or transfer ownership of tape(s) to Media server 1.
   bpmedia  -movedb -m <media_id> -newserver <hostname>  -oldserver <hostname>

Logically move media(change media owner) using "bpmedia -m media_id -newserver new_media_server".
