Below is another example of the command description for Case 4. Similar to the previous example, this
example requests the withdrawal of the relationships established within the copy source extent in the
device numbered 4202 and the copy target extent in the device numbered 4203.
Figure 71 Example(2) of FCWITHDR Command Description (for Case 4)
By executing the command described above, the relationship established with Dataset 1 is not
withdrawn because the specified extent in the device numbered 4202 is included as a part of
Dataset 1.
Figure 72 Example(2) of FCWITHDR Command (TDEVN: specified, DDSW = NO, XTNTLST parameter
specified)
Moreover, below is an example of the command description that indicates that the extent specified by
the XTNTLST parameter is located in the center of Dataset 1, and the specified extent in the device
numbered 4202 is included as a part of Dataset 1. Therefore, the relation established with Dataset 1 is
not withdrawn.
Figure 73 Example(3) of FCWITHDR Command Description (for Case 4)
NOTE: Even when the FCWITHDR command set as: SDEVN and TDEVN specified, DDSW = NO, and
XTNTLST parameter specified, is executed, this command will do nothing and end normally if either the
copy source or target extent specified by the XTNTLST parameter does not cover the extent to which any
relationship is established.
• Case 5: FCWITHDR command (SDEVN and TDEVN: specified, DDSW = YES)
Below is an example of the command description for Case 5. When YES is selected for the DDSW
parameter, the parameter value for TDEVN is ignored. Therefore, the following two examples show the
FCWITHDR SDEVN(X'4202') TDEVN(X'4203') XTNTLST(X'00000000' X'0300000E' X'20000000' X'
2000000E')
FCWITHDR SDEVN(X'4202') TDEVN(X'4203') XTNTLST(X'01000000' X'0100000E' X'21000000'
X'2100000E'
