Below is another example of the command description for Case 2. 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.
Figure 81 Example(2) of FCWITHDR Command Description (for Case 2)
By executing the command described above, 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Dataset 3, is not withdrawn because the specified extent within the device numbered 4203 is only a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.

• Case 3: FCWITHDR command (SDEVN and TDEVN: specified, DDSW = NO)
Below is an example of the command description for Case 3. This example requests the withdrawal of
all the relationships established between the device numbered 4202, which in this case is the source,
and the device numbered 4203, which in this case is the target.
Figure 83 Example of FCWITHDR Command Description (for Case 3)
In this case, only the relationships established with Dataset 3 in the device numbered 4203 are
relevant. Therefore, by executing the command described above, the relationship established with
Dataset 3 is withdrawn. Dataset 6 is specified as the copy target extent, but since the dataset specified
as the source, Dataset 5, is not in the device numbered 4202, Dataset 6 is not withdrawn. In short,
FCWITHDR TDEVN(X'4203') XTNTLST(X'00000000' X' 0000000E' X'20000000' X' 2000000E')
FCWITHDR SDEVN(X'4202') TDEVN(X'4203')
