Chapter 9. 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.
In addition to the information provided in this section, you might want to use the
ServeRAID IPSSEND program to help isolate ServeRAID problems. See
“Chapter 7. Installing and using the IPSSEND command-line program” on page 43
and “Problem-isolation and debug functions” on page 47 for information about using
the IPSSEND program.
IBM ServeRAID Support CD fails to start
If you start a server with the IBM ServeRAID Support CD in the CD-ROM drive and
the ServeRAID Manager does not start, you must reduce the number of FAT
partitions with assigned drive letters on the server.
For the startable (boot) IBM ServeRAID Support CD to work, the server cannot
have more than 22 FAT partitions with assigned drive letters.
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 47.
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.
