When BRMS operations such as Add media or Confirm move required media to or from a media library, BRMS prompts operators as needed. It instructs them to place media into, or remove media from the media library and then uses CL commands to verify that the operation is successful.
For devices such as 3494 Media Library Dataserver, a move policy or manual move of media causes the library manager to eject the tape into the convenience I/O station or the high-capacity I/O area. Additional prompting and verification is done when media, ejected from one media library location, are inserted into another. When a volume is moved into the media library, the library manager shows that the volume is in *INSERT category.
If you move a volume to a media library when media movements are to be confirmed, BRMS attempts to change the category of volumes from *INSERT to *SHARE400 or *NOSHARE, as applicable to the media class. If at the time of the confirm move, the volume has not been placed in your media library, a message is logged in the BRMS log. These volumes must be changed to *SHARE400 before they can be used by BRMS.
If move verification is not enabled, BRMS attempts to change the category of volumes that move into a media library from *INSERT to *SHARE400 or *NOSHARE immediately. This can cause a problem, as common maintenance (STRMNTBRM command) is run at night after backups have completed, and volumes have not been moved off site. In this case, it may be worthwhile to use the PRTMOVBRM command during the day before the move is to take place. Use the PRTMOVBRM command to ensure that you collect the volumes and insert them into the media library before the MOVMEDBRM command is actually processed.
