ServeRAID controller messages
This section lists the ServeRAID messages that might appear during system
startup.
The ServeRAID controllers provide a Device Event Log that collects statistics on the
number and types of events that occur on a selected physical drive. After correcting
a problem with the disk array, clear the log so that you can identify any subsequent
errors quickly. For information about clearing the event log, see “eraseevent” on
page 72.
All physical drives contain unique identifiers, such as the drive serial number and
manufacturer. During configuration, the ServeRAID controller stores this information.
Following are messages associated with the ServeRAID subsystem in alphabetical
order.
