Appendix B. IXFP Command Examples
In this appendix we present the syntax and use of the various IXFP commands.
B.1 SNAP Command
In this section we present examples of the IXFP SNAP command. The command
syntax is followed by examples of using the command.
Remember: Before you can use the SNAP option, you must bring the target
offline by using the VSE/ESA DVCDN command.
B.1.1 Syntax
Figure 24 shows the syntax of the SNAP command.

Figure 24. Syntax of IXFP SNAP Command: Details
SNAP identifies this command as a SNAP command.
source The device ID=(cuu) or the VOL1 label of the source device
that the user wants to be used as the source when copying
data to a target device. If the source device is identified by its
VOLID, it must be either the only volume with that VOLID or the
only volume with that VOLID that is up (DVCUP). Otherwise an
error message will be issued. The whole volume will be
copied unless the operator has provided additional information
that either identifies a cylinder range or a DSN on the source
device that he or she wants to be copied.
scyl-scyl Specifies the decimal start cylinder and end cylinder
range where copying is to start and to end on the
source device. Cylinder is the smallest entity that can
be specified for any SNAP command function. The
highest (end) cylinder number must not exceed 32767
or the device′s primary number of cylinders and the
start cylinder number must not be higher than the end
cylinder number.
scyl.ncyl Specifies the decimal start cylinder where copying is
to start on the source device and provides the number
of cylinders (ncyl) that should be copied. Cylinder is
the smallest entity that can be specified for any SNAP
command function. The highest resulting cylinder
number must not exceed 32767 or the device′s number
of primary cylinders.
DSN= The data set name identifying the file on the source
device that the operator wants to be copied onto the
target device. The file must be a non-VSAM file. The
file will be copied into the exact extent boundaries
where it was located on the source device. Sequential
