Chapter 28. Orientation to OS/390 Console Operation
28.1 Introduction
There are enough differences between VSE and OS/390 operations to warrant
each operator and systems programmer attending a class on the subject.

This chapter is intended only to provide the reader with an overview of OS/390
console operations on a single system. (Multi-system or sysplex operation are
not covered here.) It is not intended to replace more formal training which
should be given to all OS/390 operators and system programmers. It is also not
intended to replace the standard OS/390 Operations publications listed herein.

The OS/390 system can be operated without a lot of manual intervention if set up
correctly, and various automation products are used.

28.1.1 Operating Hardware Consoles
Before you can operate the system, you must be able to configure the hardware
elements, and initialize the processor using the hardware console which is
usually integrated into the service processor of the CPU. These consoles vary
from processor to processor, and most should be familiar to the VSE operator
using the same hardware:

from processor to processor, and most should be familiar to the VSE operator
using the same hardware:
•
Hardware Management Console (HMC)
The IBM S/390 CMOS (9672) and Multiprise processors have hardware
consoles which are used to power on, IPL, reset, configure, and power off
the processor. (The HMC is not required for an S/390 Multiprise.)

S/390 Multiprise Stand-Alone Support Element (SASE)
This an external console running OS/2 Warp which can be used for hardware
management and has a look and feel similar to the HMC.

Other S/390 System Consoles
The IBM ES/9000 9021, 9121, and 9221 processors have integrated system
consoles using the Service Processor or Processor Control Element (PCE) to
power on, IPL, reset, configure, and power off the processor.

All of these hardware system consoles have interfaces for operating the OS/390
software, but are not usually used except for emergency or test.

28.2 Understanding the Operator Interfaces
Operator commands come in many flavors (MVS, JES2, SDSF, other subsystem),
and can be entered through many different interfaces, such as:
