Manual Disabling of Components
The system controller provides component-level status and user-controlled
modification of component status.
Set the component location status by running the
setls
command from the console.
The component location status is updated at the next domain reboot, board power
cycle, or POST execution (for example, POST is run whenever you perform a
setkeyswitch on
or
off
operation).
Note – The
enablecomponent
and
disablecomponent
commands have been
replaced by the
setls
command. These commands were formerly used to manage
component resources. While the
enablecomponent
and
disablecomponent
commands are still available, use the
setls
command to control the configuration
of components into or out of the server.
The
showcomponent
command displays status information about the component,
including whether or not it has been disabled.
Environmental Monitoring
The system controller (SC) monitors the server’s temperature, cooling, and voltage
sensors. The SC provides the latest environmental status information to the Solaris
Operating System. If hardware needs to be powered off, the SC notifies the Solaris
OS to perform a system shutdown.
