Adding Objects in SYSGEN
When you use SYSGEN to add objects to the system configuration, there are four I/O
Configurator commands available: ACLASS, ADEV, APATH and AVOL. They are defined in
Table 5-3.. For more detailed information read Performing System Manager Tasks.
Table 5-3. I/O Configurator Add Commands
Command Definition Examples
ACLASS Creates a new class name and associates devices to
the new class. You use the ACLASS command to add
a class name designation to a device that is already
configured with the ADEV command. You also
specify the mode with this command, which can be
one of JOB (accepts jobs and sessions), IN (input
only), OUT (output only), CIO (concurrent I/O), NCIO
(nonconcurrent I/O), RANDOM (direct-access device
such as a disk), and DEFAULT (a mode assigned
when the system is initialized).
