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-scylSpecifies 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.
	D S N =	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
