Event Notification
The EMS hardware event monitor polls environmental services on the LCC and
reports any changes in the status of monitored components. Depending on how
the monitor is set up, you can receive messages at the console, in e-mail, in a log
file, or through third-party applications. These messages are likely to be the first
indication of a problem with a disk system.
Events are reported for changes in temperature, voltage, and the status of
replaceable components.
