Figure 59 Diagram of the FCWITHDR Command Processing (SDEVN and TDEVN
Specified, D DSW = YES) (Case 5)
Case 6: SDEVN and TDEVN Specified, D DSW = YES, XTNTLST Parameter
Specifi
ed
Among the relationships established with the device specified by SD EVN, all the relationships that
partly or entirely include the copy target extents specified by the XTNTLST parameter are withdrawn.
The information about the specified TD EVN a nd the c opy target extents specified by the XTNTLST
param
eter are ignored.
Note:
When the FCWITHDR comm and is executed with the DDSW parameter set to YES and the
XTNTLST parameter specified, only the XTNTLST parameter values specified for the copy source extent
are p
ut into effect. When there are no relationships existing within the copy source extent specified by the
XTNTLST parameter values, the FCWITHDR command will d o nothing and end n ormally.
Below are t wo examples of the command descriptions for Case 6. Both examples request the withdrawal
of all
those relationships among the relationships established with the device num bered 4202 that are
included in the extent specified by the XTNTLST parameter. When the DDSW parameter is set to YES,
the
TDEVN parameter values and the XTNLST parameter values for the copy target extent are ignored.
The
refore, the t wo command descriptions below both bear the same result.
