The DASD device driver has a new attribute copy_pair to make storage
server copy pairs known to the driver.
Add this attribute to zdev.
Usage example:
Add two copy pairs 1000,2000 and 1000,3000 to a DASD device 1000
$ chzdev dasd 1000 copy_pairs=1000,2000 copy_pairs=1000,3000
or
$ chzdev dasd 1000 copy_pairs="1000,2000 1000,3000"
To add a third copy pair later on:
$ chzdev dasd 1000 copy_pairs=1000,4000
To remove all copy pairs from the device 1000:
$ chzdev dasd 1000 -r copy_pairs
