Starting or Stopping a Subsystem, Subsystem Group, or Subserver

Use the startsrc command to start a System Resource Controller (SRC) resource such as a subsystem, a group of subsystems, or a subserver.

• From the /etc/inittab file so the resource is started during system initialization
• From the command line
• With SMIT.

When you start a subsystem group, all of its subsystems are also started. When you start a subsystem, all of its subservers are also started. When you start a subserver, its parent subsystem is also started if it is not already running.

Use the stopsrc command to stop a SRC resource such as a subsystem, a group of subsystems, or a subserver.

Prerequisites

• To start or stop an SRC resource, the SRC must be running. The SRC is normally started during system initialization. The default /etc/inittab file, which determines what processes are started during initialization, contains a record for the srcmstr daemon (the SRC). To see if the SRC is running, enter ps -A and look for a process named srcmstr.
• The user or process starting an SRC resource must have root user authority. The process that initializes the system (init command) has root user authority.
• The user or process stopping an SRC resource must have root user authority.
