The input disk is the disk or one of the disks which FDDRL is to copy or save. In the case of //COPY-DISK and //DUMP-DISK statements, it is defined by the DISK operand, while with the //COPY-PUBSET and //DUMP-PUBSET statements it is defined by the PUBSET operand.
With the //COPY-DISK, //COPY-PUBSET, //DUMP-DISK and //DUMP-PUBSET statements you cannot specify the device type of the input disk. By default it is set to the general disk type “STDDISK“, unless a clear special device type can already be determined when the statement is entered: with //COPY-PUBSET and //DUMP-PUBSET, FDDRL attempts to ascertain the special device type from the master catalog or on the basis of the attached devices. If this is not successful, the input disk is requested with the general disk type “STDDISK” and the special device type is registered after the assignment.
The input disk must have a valid BS2000 standard volume label (SVL), otherwise it cannot be saved. The disk must be exclusively available to FDDRL: it must be attached, but its catalog may only be imported if disk copies were split in the event of disk mirroring with SHC-OSD.
FDDRL supports the saving of a complete SM pubset as long as it does not comprise more than 255 individual disks. Any attempt to save an individual volume set is rejected, as restoration of only this volume set would produce an inconsistent SM pubset.
