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 in an error.
• The size of the specified copy source and target extents must be the same.
• The relationship must be established with INCREMENTAL = NO or must be established without
INCREMENTAL = NO or must be established without INCREMENTAL.
CAUTION: When the relationships are withdrawn by the FCWITHDR command executed with
the DDSW parameter set to NO or without setting the DDSW parameter, the data integrity of the
T-VOL cannot be guaranteed.
Case 1: TDEVN Specified, DDSW = NO
All the relationships established with the copy target extents existing in the device specified by
TDEVN are withdrawn. The relationships established with the copy source extents existing in the
specified volume are not withdrawn.
