Figure 33 FCWITHDR command processing (SDEVN and TDEVN: specified, DDSW = NO, XTNTLST
specified) (for Example 4A)
The following is another example of the command description for Case 4: SDEVN and TDEVN:
specified, DDSW = NO, XTNTLST specified. Similar to the previous example, this example requests
the withdrawal of the relationships that are established within the copy source extent in the device
numbered 4202 and the copy target extent in the device numbered 4203.
FCWITHDR SDEVN(X'4202') TDEVN(X'4203')
XTNTLST(X'00000000' X'0300000E' X'20000000'
X' 2000000E')
When you execute the FCWITHDR command described in the example, 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with Dataset 1 is not withdrawn because the specified extent in the device numbered 4202 is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. See the following figure:
