Monitoring the System Using Sun Advanced
Lights Out Manager
Sun Advanced Lights Out Manager (ALOM) enables you to monitor and control
your server over a serial port or a network interface. The ALOM system controller
provides a command-line interface that enables you to administer the server from
remote locations. This may be especially useful when servers are geographically
distributed or physically inaccessible.
ALOM also lets you remotely access the system console and run diagnostics (like
POST) that would otherwise require physical proximity to the server's serial port.
ALOM can send email notification of hardware failures or other server events.
The ALOM system controller runs independently, and uses standby power from the
server. Therefore, ALOM firmware and software continue to be effective when the
server operating system goes offline, or when power to the server itself is turned off.
ALOM lets you monitor the following on the Sun Fire V440 server.
