3. Use ipssend format to restart the format of the physical drive. The syntax is: ipssend format controller channel sid where: • controller is the ServeRAID controller number (1-12) • channel is the channel number for the device (1, 2, or 3) • sid is the SCSI ID for the device (0-15) After the format is complete, the ServeRAID controller will be able to recognize the drive again. Recovering from a failure in a failover-environment In a failover environment, when the ServeRAID device driver is unable to send a command to the primary controller and the primary controller does not respond to a reset command, the device driver attempts to failover to the secondary controller. Note: Loose cables or defective physical drives will not cause a failover to occur. Replacing a non-hot-plug controller in a failover pair If a failed controller is not in a hot-plug PCI slot, do the following to replace it: 1. Shutdown the server. 2. Replace the failed controller. 3. Reconfigure the new controller. Notes: 1.Be sure the firmware level of the new controller is the same as the controller you are replacing. Be sure to use the same controller name, partner name, and SCSI initiator ID for the controller you are replacing. 2.For detailed instructions, refer to the Hardware Maintenance Manual for the ServeRAID controller being serviced. If the failed controller is in a hot-plug slot, refer to the documentation that comes with the server for instructions for replacing the controller. Diagnostic programs and error messages The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server. Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel. Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears. The following sections contain the error codes that might appear in the detailed test log and summary log when running the diagnostic programs. The error code format is as follows: 24 Hardware Maintenance Manual: Netfinity 7600 - Type 8665 Models 1RY, 2RY
