Entering a Configurator Subsystem
To access any of the four configurator subsystems, enter the appropriate
command at the SYSGEN> prompt. For example, to access the IO
Configurator, enter:
SYSGEN>IO
The prompt IO> is displayed.
How the SYSGEN Configurators Work
The configurators operate on the information contained in the current
basegroup.
The various configurator files contain information on device classes, I/O
paths, ldev numbers, current volume names, and similar data. Even after
changes are made in one or more configurator files, the current
configuration remains valid until the new information is saved using the
SYSGEN KEEP command, and until the system is rebooted using the new
configuration.
A Detailed Look at the Configurator Commands
Each of the four configurators has its own set of commands and options,
along with an online help facility. Configuration commands can be
classified as either command only, or command with parameter(s).
Configuration commands with parameters can be specified in one of the
following ways:
COMMAND [positional-parameters]
[keyword parameters ]
[options ]
Most of the configurator commands have both required and optional
parameters. For example, let's look at the syntax for ADEV, which is the
command used to add a device to the configuration.

Example 3-2. The ADEV Command
You must supply the following required parameters: the ldev number,
device I/O path, and the device product identification number. In most
cases, SYSGEN supplies the rest of the information from a device default
file, IODFAULT.PUB.SYS.
The command can be specified in any of three ways:
IO>ADEV 21 16.0.0 HP7937 ** Other parameters supplied **
IO>ADEV 21 16.0.0 HP7937 CLASS=(DISK,SPOOL)** Keyword
value supplied **
IO>ADEV 21 16.0.0 HP7937,,,,SPOOL **Value supplied as
positional parameter**
