Reserved file:
The second file on the export list volume is reserved for future use. Even though it is presently not used, you
must create this file. It must contain at least one record, although the TS7700 does not check its contents.
For example, you could create a record as:
RESERVED FILE
Export status file:
The third file on the export list volume is used by the TS7700 for storing status information from the copy
export operation. You must create the file with one record as illustrated below, starting in the first column:
EXPORT STATUS 01 <user field>
The optional user field is a maximum of 16 characters long, separated with a blank from the version
number.
After the copy export operation is completed, this file contains additional records reporting on the export
results including the logical volumes exported and the status of all physical volumes in the copy-exported
state.
Note: The TS7700 may update the version number on the status file record that was written as additional
information is added to the status file.
A basic utility like IEBGENER is the simplest way to create the export list file volume. The following is
sample JCL which writes the required files on the export list volume using a scratch volume (assumes the
secondary physical volume pool used for copy export is pool 09 and the physical volumes are to be directly
ejected):
//EXPORT JOB 1,'EXPORT',MSGLEVEL=(1,1)

//* DO NOT USE COMPACTION WHEN WRITING THE REQUEST FILE
