After transferring the Database Management for Db2 for z/OS product pax.Z DVD image to USS directory
and running the pax -rvf command, the unpax process failed with the error:
pax: checksum error on tape (got f18e, expected 0)
The cause of this condition was due to not specifying 'bin' prior to running the ftp 'get' for the pax.Z file.
Issue the 'bin' command to keep the file transfer in binary (image) prior to the 'get' command.
