NOTE:
• All combinations other than shown in Table 57 will result in rejection of this command.
• The information specified by the XTNTLST parameter is supported only when the following conditions
are fully met:
• The information specified by the XTNTLST parameter must be for both the source and target. If the
information specified by the XTNTLST parameter is only for one of the two, the copy operation will
result as an error.
• The size of the specified copy source and target extents must be the same.
Each of the example cases listed in Table 57 is further explained below with the command description and
illustration.
4 Specified Specified NO Specified Specified Among the relationships established
between the source device specified by
SDEVN and the target device specified
by TDEVN, 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parameter are withdrawn.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withdrawn. See Figure Figure 69,
Figure 71, and Figure 73.

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specified by SDEVN are withdrawn.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withdrawn after the background copy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are withdrawn after the copy operation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target, the relationships are withdrawn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.
The information on the device specified
by TDEVN is ignored. See Figure 74.
6SpecifiedSpecified
or not
specified
YES Specified Specified Among the relationships established with
the device specified by SDEVN, all the
relationships that partly or entirely
include the copy target extents specified
by the XTNTLST parameter are
withdrawn. The information about the
specified TDEVN and the copy target
extents specified by the XTNTLST
parameter are ignored. See Figure 76.
