Enhancements

Several enhancements have been made since the introduction of DUPOPT command:

• DUPOPT no longer requires the source and target volume to be in the same optical library.
• For target media with the *HPOFS media format, the target media capacity no longer has to be identical to the source media capacity. It can now be equal to or larger than the source media.
• For *WORM media the target media type no longer has to be *WORM. You can use either *WORM or *ERASE media.
• Improved device error recovery.
• Improved performance.
• The addition of the cross device support (library to library, stand-alone to stand-alone).
• The addition of the unload support for stand-alone devices.
• When duplicating a volume in a stand-alone or virtual device, you can create an exact copy with the same volume identifier as the source.

In the following example, the system duplicates the volume in optical device OPT01 to the volume in optical device OPT02. Upon completion, the target volume identifier will be MYBACKUP, and the system unloads the media from the device.
