Below is an example of the command description for Case 2. This example requests the withdrawal of
all
the relationships established with the copy target extents included in the specified extents within
thedevicenumbered4203.
FCWITHDR TDEVN(X'4203') XTNTLST(X'00000000' X' 03000000E' X'20000000' X' 2300000E')

In this case, the specified extents in the device numbered 4203 are contained in Dataset 3. Therefore,
by executing the command described above, the relationship established with Dataset 3 is withdrawn.
In shor t, there are two relationships before executing the command above, and after executing the
command, there is only one relationship.
Dataset 1：CCHH＝(00000000 、0200000E)
