Chapter 3. z/OS notes 31
Moving an emulated 3390 volume to (or from) a non-zPDT system is a little more complex,
because it must be handled in a System z format instead of a Linux format. The traditional
method is to dump the volume to tape (using the ADRDSSU program) and then restore the
tape on the target system. This method can also be used with emulated tapes (in awstape
format), provided that both the sending and receiving systems can use this format.
This section describes another method for moving a volume from z/OS on a zPDT system to
a non-zPDT system. This example assumes the target system cannot use awstape format
(otherwise we would use the easier method of creating a dump tape in awstape format). We
assume there is a network connection between the zPDT Linux base system and the target
z/OS system.

Preparation
We need z/OS disk space to hold a 3390 volume dump and to hold a reformatted volume
dump. These can be large data sets. You may have sufficient space on existing z/OS
volumes; we elected to create three new volumes for holding large temporary data sets. We
did this using normal zPDT techniques. First we created three new emulated 3390 volumes
using the alcckd command (done while zPDT is not operational). The placement (/z), model
(3390-3), and names of the files (TEMPnn) are all arbitrary.
$ alcckd /z/TEMP01 -d3390-3
$ alcckd /z/TEMP02 -d3390-3
$ alcckd /z/TEMP03 -d3390-3
We then added these volumes to our devmap. The addresses specified (AA0, AA1, and AA2)
are unused address that are known as 3390 devices for our z/OS. (That is, z/OS has these
addresses specified as 3390 devices in the IODF it uses during IPL. The AAx addresses are
suitable for the default IODF in the z/OS AD systems.)
