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The relationships included in the extents specified by the XTNTLST parameter are withdrawn.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relationships that are only partly included in the specified extents are not withdrawn.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the relationship established with Dataset 3 is withdrawn.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.

The following is another example of the command description for Case 2: TDEVN: specified,
DDSW = NO, XTNTLST specified. Similar to the previous example, 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'
0000000E' X'20000000' X' 2000000E')
By executing the command described in the example, the relationship established with the specified
target, Dataset 3, is not withdrawn because the specified extent within the device numbered 4203
is only a part of Dataset 3. See the following figure:
