Figure 31 FCWITHDR command processing (TDEVN: specified, DDSW = NO, XTNTLST specified)
(for Example 2B)
Case 3: SDEVN and TDEVN Specified, DDSW = NO
All the relationships established between the source device specified by SDEVN and the target
device specified by TDEVN are withdrawn.
The following is an example of the command description for Case 3: SDEVN and TDEVN: specified,
DDSW = NO. 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.
FCWITHDR SDEVN(X'4202') TDEVN(X'4203')
In this case, only the relationships established with Dataset 3 in the device numbered 4203 are
relevant. See the following figure: Therefore, by executing the FCWITHDR command described in
the example, the relationship established with Dataset 3 is withdrawn.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numbered 4202, Dataset 6 is not withdrawn.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, there are three relationships before executing
the FCWITHDR command shown in the example, and after executing the command, there are only
two relationships.
