There are three relationships before executing the command above, and after executing the command,
there is only one relationship.
Figure 77 Example of FCWITHDR Command (SDEVN and TDEVN: specified, DDSW = YES, XTNTLST
parameter specified)
NOTE: When the FCWITHDR command is executed with DDSW parameter set to YES and XTNTLST
parameter specified, only the XTNTLST parameter values specified for the copy source extent are put into
effect. When there are no relationships existing within the copy source extent specified by the XTNTLST
parameter values, the FCWITHDR command will do nothing and end normally.
The FCWITHDR command can be used to withdraw relationships established for copy operations set either
in COPY or NOCOPY mode. When the FCWITHDR command is executed with DDSW parameter set to
NO or without setting the DDSW parameter, the relationships specified in the command are withdrawn
when the command is executed. When the FCWITHDR command to withdraw relationships established for
copy operations set in COPY mode is executed while the background copy operation is in progress, and
the relationships specified in the command are withdrawn after the ongoing background copy operation is
stopped and cancelled.
When the FCWITHDR command for withdrawing relationships established for copy operations set in
COPY mode is executed with DDSW parameter set to YES, the relationships established with the specified
copy source extent(s) on the volume specified by SDEVN are withdrawn after the background copy is
completed. When the FCWITHDR command for withdrawing relationships established for copy operations
set in NOCOPY mode is executed with DDSW parameter set to YES, the relationships established with the
specified copy source extent(s) on the volume specified by SDEVN are withdrawn only after the copy
operation mode is switched to COPY mode, followed by the execution and completion of the background
copy operation. When the FCWITHDR command is executed with DDSW parameter set to YES, the
relationships established with the specified copy target extent(s) on the volume specified by SDEVN are
withdrawn.
When the FCWITHDR command is executed without any relevant relationships to withdraw, the command
will do nothing and end normally. Moreover, the FCWITHDR command will do nothing and end normally
when the existing relationships do not fall in with any of the range specified by the XTNTLST parameter.
