Duplicating a BRMS Volume Set of More Than 300 Volumes

When using BRMS to duplicate media, DUPMEDBRM, there is a limit of 300 volumes that can be in a serial set. If there are more than 300 volumes in a set, the DUPMEDBRM will fail as the DUPTAP command has a limit of 300 volumes

If you need to duplicate the set, it will have to be broken up into different commands.

Example

You will need to know the list of volumes and the sequences on the volumes. This can be obtained using WRKMEDBRM option 6 and WRKMEDIBRM

Assume there are 365 volumes in the serial set. The first volume in the set is BRM000 , the 250 volume is BRM249 and the 365th volume is BRM364.

The last complete sequence on BRM250 is 387

These are the commands you would need to run

DUPMEDBRM VOL(BRM000) FROMSEQNBR(1 387) - This will duplicate the first set of volumes (251)

DUPMEDBRM VOL(BRM250) FROMSEQNBR(388 *LAST) TOSEQNBR(*END) - This will duplicate From sequence 388 on BRM250 to the last file sequence of the set, in this case volume BRM364
