The data sets and the partitions they hold have the following naming convention.
Dataset Names Partition Names
LINUX.Vvolser.PART0001.type /dev/dasd/yyyy/part1
LINUX.Vvolser.PART0002.type /dev/dasd/yyyy/part2
LINUX.Vvolser.PART0003.type /dev/dasd/yyyy/part3
Where volser is the volume serial number of the volume that the data set is on. yyyy is the device number of the volume in the Linux environment. Type can be NATIVE or SWAP. Only NATIVE partitions need to be backed up. SWAP partitions are the Linux equivalent to page packs.
