Figure 28 Diagram of the FCWITHDR Command Processing (TDEVN: specified, DDSW = NO)( for
Case 1)
Case 2: TDEVN specified, DDSW = NO, XTNTLST parameter specified
The relationships included in the extents specified by the XTNTLST parameter are withdrawn.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relationships that are only partly included in the specified extents are not withdrawn.
The following example shows the command description for Case 2. 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.
Example 21 The FCWITHDR command description (TDEVN: specified, DDSW=NO, XTNTLST specified)
FCWITHDR TDEVN(X'4203') XTNTLST(X'00000000' X' 03000000E' X'20000000' X' 2300000E')
In this case, the specified extents in the device numbered 4203 are contained in Dataset 3. See
the following figure. Therefore, by executing the FCWITHDR command described in the example,
the relationship established with Dataset 3 is withdrawn. In short, there are two relationships before
executing the FCWITHDR command, and after executing the FCWITHDR command, there is only
one relationship.
