About Remote System Control (RSC)

Remote System Control (RSC) is a secure server management tool that lets you
monitor and control your server over modem lines or over a network. RSC provides
remote system administration for geographically distributed or physically
inaccessible systems. The RSC software works with the System Service Processor
(SSP) on the Enterprise 250 main logic board. The SSP provides both serial and
Ethernet ports for connections to a remote console.
Once RSC is configured to manage your server, you can use it to run diagnostic tests,
view diagnostic and error messages, reboot your server, and display environmental
status information from a remote console. If the operating system is down, RSC will
notify a central host of any power failures, hardware failures, or other important
events that may be occurring on your server.
The RSC provides the following features:
Remote system monitoring and error reporting (including output from POST and
OBDiag)
Remote reboot on demand
Ability to monitor system environmental conditions remotely
Ability to run POST and OBDiag tests and use SunVTS from a remote console
Remote event notification for over-temperature conditions, power supply failures,
fatal system errors, or system crashes
Remote access to detailed event and error logs
Remote console functions on serial and Ethernet ports
For More Information
For information about configuring and using RSC, see the Remote System Control
(RSC) User's Guide, provided with the RSC software.
Note – By default, diagnostic status and error messages are displayed on the local
system console or terminal. If your server has been reconfigured to display output
on an RSC console, diagnostic results will not display locally. To redirect diagnostic
messages to the local console, you must use the OpenBoot PROM command
diag-output-to and modify the OpenBoot PROM variables input-device and
output-device. For additional details, see the Remote System Control (RSC) User's
Guide.
