Solving ServeRAID problems This section describes the ServeRAID text and numeric messages that might appear 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. 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 array, clear the log so that you can identify any subsequent errors quickly. For information about clearing the event log, see "eraseevent" on page 170. All physical drives contain unique identifiers, such as the drive serial number and manufacturer. During configuration, the ServeRAID controller stores this information. ServeRAID startup messages During power-on self-test (POST), the ServeRAID controller compares the stored configuration information to the configuration that is actually present. If a discrepancy exists, one or more status messages appear after POST completes, but before the operating system loads. Notes: 1.When the ServeRAID controller requires your input, a list of function keys will appear below the message. 2.Where the Action information tells you to start the IBM ServeRAID configuration program, insert the IBM ServeRAID Support CD into the CD-ROM drive; then, restart the server. The Action column also provides general information about the message. 3.Where SID or ch appears in these messages, sid is the SCSI ID for the device, and ch is the channel to which the device is attached. 4.Where m or n appears in these messages, a number will appear in the actual message. Following are messages associated with the ServeRAID subsystem in alphabetical order. A new drive was installed. Explanation: When the ServeRAID controller detects a new drive that is not part of the current configuration, the following message appears: x new ready drives found where x is the number of ready drives found. Action: This is an information message. No action is required. Diagnostics 13
