By executing the command described in the example, the relationship established with the specified
target, Dataset 3, in the device numbered 4203, is withdrawn (see the following figure). But the
relationship established with Dataset 4 is not withdrawn because it is specified as the dataset
source. In short, there are two relationships before executing the command above, and after
executing the command, there is only one relationship.

Figure 34 Diagram of the FCWITHDR command processing (TDEVN: specified, DDSW = NO) (for
Case 1)

Case 2: TDEVN Specified, DDSW = NO, XTNTLST Parameter Specified

The relationships included in the extents specified by the XTNTLST parameter are withdrawn. The
relationships that are only partly included in the specified extents are not withdrawn.

The following 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 the device numbered 4203.

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. See
the following figure: Therefore, by executing the FCWITHDR command described in the example,
the relationship established with Dataset 3 is withdrawn. In short, there are two relationships before
executing the FCWITHDR command, and after executing the FCWITHDR command, there is only
one relationship.
