the ID label of the volume set as the source is copied to the volume set
as the target. When COPYVOLID command is executed, the volume

copied to the backup tape or disk. In this case, it is not necessary to
specify COPYVOLID to copy the volume label.

DUMPCONDITIONINO is used when you want to specify that the
purpose of the copy operation is to create a backup copy and not for
using the copied volume for application.
