Establishing Version 2 Relationships by Extents Using the TSO Command
When you establish Version 2 relationships by extents with the FCESTABL command, the following
parameters are available in addition to the parameters defined in
(page 83) .
Table 54 Parameters for the FCESTABL Command (Version 2/Dataset Copying)
Description Value Parameter
Specifies the extent (copy range) by
setting the same starting and ending Extents (copy range) EXTENTS
addresses of the source and target with
CCHH (cylinder and head numbers).
From the copy source, the specified
data is copied to the same offset
position on the copy target. Up to 32
extents can be specified. When
EXTENTS is not specified, the data on
all the tracks is copied.
Specifies the extent (copy range) by
setting the starting and ending Extents (copy range) XTNTLST
addresses of the source, and the
starting and ending addresses of the
target with CCHH (cylinder and head
numbers). From the copy source, the
specified data is copied to a different
offset position on the copy target. Up
to 32 extents can be specified. When
XTNTLST is not specified, the data on
all the tracks is copied.
To execute the XTNTLST parameter, the
size of the copy source extent and the
copy target extent must be the same.
When the FCESTABL command with the EXTENTS parameter specified is executed, only the data
on the copy source extents specified by the EXTENTS parameter is copied from the volume specified
as the source by SDEVN to the volume specified as the target by TDEVN. For example, when you
copy only dataset 2, the copy operation processes as shown in
(page 100) . When you do not
specify the EXTENTS parameter, the entire source volume is copied to the target volume.
