Figure 33 FCWITHDR command processing (SDEVN and TDEVN: specified, DDSW = NO, XTNTLST
specified)
The following example shows 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1 is not withdrawn.
Example 26 FCWITHDR command description (SDEVN and TDEVN specified, DDSW=NO, XTNTLST
specified)
FCWITHDR SDEVN(X'4202') TDEVN(X'4203') XTNTLST(X'01000000' X'0100000E' X'21000000' X'2100000E'
Case 5: SDEVN and TDEVN Specified, DDSW = YES
All the relationships established with the extents in the source or target device specified by SDEVN
are withdrawn.
If the device specified by SDEVN is the source and if the relationships are set to the COPY mode,
the relationships are withdrawn after the background copy process is completed.
If the device specified by SDEVN is the source and if the relationships are set to the NOCOPY
mode, the relationships are withdrawn after the copy operation mode is changed to COPY mode
and then the background copy process is completed. If the device specified by SDEVN is the target,
the relationships are withdrawn immediately. If the device specified by SDEVN is the source and
the relationship is established with INCREMENTAL = YES, the relationship will be maintained after
the background copy operation is completed. The information on the device specified by TDEVN
is ignored.
The following example shows 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 same content represented by a different description, both requesting the withdrawal of
all the relationships established with the device numbered 4202.
