Chapter 3  Defining Input/Output Devices 

With the introduction of version C.55.00 of MPE/iX, there are two ways to
define input and output devices on a system:  using SYSGEN's I/O
Configurator or using the IOCONFIG utility.  Both methods provide
information about the input and output devices configured on a system and
let you make changes to the configuration as necessary.  The key
difference is that using IOCONFIG changes the configuration while the
system remains online, whereas to activate configuration changes made
with SYSGEN, you must issue a separate command (DOIONOW) after making the
changes, or reboot the system with the START NORECOVERY option, or
generate a new System Load Tape to update this (or another) system.

This chapter explains the following topics:

   *   using the SYSGEN I/O Configurator to get current configuration
       information, change the configuration, and define new I/O devices
       on your system.

   *   using the command file DOIONOW to immediately implement
       configuration changes you make using SYSGEN's I/O Configurator.

   *   using the IOCONFIG utility to view and change the IO configuration
       while the system remains online.
