In this case, only the relationships established with Dataset 3 in the device numbered 4203 are
relevant. See

“FCWITHDR Command Processing (SDEVN and TDEVN Specified, DDSW = NO)

(for Case 3)” (page 116)

. Therefore, by executing the FCWITHDR command described in

“FCWITHDR

Command Description (SDEVN and TDEVN Specified, DDSW = NO) (for Case 3)” (page 115)

,

the relationship established with Dataset 3 is withdrawn. Dataset 6 is specified as the copy target
extent, but because the dataset specified as the source, Dataset 5, is not in the device numbered
4202, Dataset 6 is not withdrawn. In short, there are three relationships before executing the
FCWITHDR

command shown in

“FCWITHDR Command Description (SDEVN and TDEVN Specified,

DDSW = NO) (for Case 3)” (page 115)

, and after executing the command, there are only two

relationships.

Figure 70 FCWITHDR Command Processing (SDEVN and TDEVN Specified, DDSW = NO) (for Case
3)

Case 4 (a, b): SDEVN and TDEVN Specified, DDSW = NO, XTNTLST Parameter Specified

Among the relationships established between the source device specified by SDEVN and the target
device specified by TDEVN, 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parameter are withdrawn.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are not withdrawn.

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 will end normally.
Either the copy source or target extent specified by the XTNTLST parameter does not cover an
extent to which any relationship is established.
