Take the following steps to save media information for duplicate
volumes:
Run the BRMS backup on the original volume and specify that you
want to save the media information.
Create the duplicate volumes with the DUPMEDBRM command.
Run media movement by using the Move Media using BRM (MOVMEDBRM)
command so that the two sets of volumes (original and duplicate) go
to different locations.
Perform another save of the media information by using the Save
Media Information using BRM (SAVMEDIBRM) command.
Move the volumes that SAVMEDIBRM command creates in the previous
step to the same location as the duplicate volumes.
Create the recovery report by specifying the location of the duplicate
volumes in the STRRCYBRM LOC (duplicate-volume-location).
