Chapter 18. Solving ServeRAID problems
This section describes the ServeRAID text and numeric messages that might be
displayed during startup. This section also includes some basic information about
rebuilding a defunct drive.
IBM ServeRAID Support CD warning message while starting
If you start a server with the IBM ServeRAID Support CD in the CD-ROM drive, the
following warning message might be displayed:
You passed an undefined mode number.
Press <RETURN> to see video modes available,
<SPACE> to continue or wait 30 secs
Press the Spacebar to continue starting the IBM ServeRAID Support CD. The

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 86.
All physical drives contain unique identifiers, such as the drive serial number and
manufacturer. During configuration, the ServeRAID controller stores this information.
The following are the messages associated with the ServeRAID subsystem listed in
alphabetical order.
