Case 1: TDEVN specified, DDSW = NO

In Case 1, all relationships established with the target extents in the device specified by TDEVN are withdrawn.

An example of the FCWITHDR command for Case 1 follows. This command requests the withdrawal of all relationships established with target extents in device 4203.

FCWITHDR TDEVN(X'4203')

When this FCWITHDR command is executed, the relationship established with the specified target, Dataset 3 in device 4203, is withdrawn, but the relationship established with Dataset 4 is not withdrawn because it is specified as the source. There are two relationships before this FCWITHDR command is executed, and there is only one relationship after this FCWITHDR command is executed.
