Copying physical partitions
BMC AMI Copy
DSNUM integer, DSNUM PART, and DSNUM DATASET table space copies and index space copies use physical partition numbers and each partition copy is registered with its logical partition number in the LOGICAL_PART column of SYSCOPY or BMCXCOPY.
The number written into the LOGICAL_PART column is the logical partition number corresponding to the physical partition number at the time associated with the copy registration START_RBA.
A DSNUM ALL copy is registered with zero in both the DSNUM and LOGICAL_PART columns.
