Subsystems in G-Series RVUs
Subsystems in G-Series RVUs
A system running a G-series RVU has multiple subsystems that handle the
configuration and management of subsystem-specific generic processes, I/O
processes, and system hardware. This illustration is an overview of the configuration
components in these systems.

Component Function
CONFIG system
configuration database file
Contains information about the location and characteristics of
all system components. This file is on the
$SYSTEM.ZSYSCONF subvolume.
$ZCNF configuration utility
process
Is the database server for the subsystem managers and
monitor processes. Controls access to the system
configuration database. Manages requests for information
about the CONFIG file. Starts and maintains the $ZPM
persistence manager process.
$ZPM persistence
manager process
Starts and maintains persistence of subsystem managers and
monitor processes.
Starts, stops, and (optionally) restarts generic processes.
Coordinates system load and processor reload activities.
Subsystem managers and
monitor processes
Configure and control subsystem devices.
