[chars]. Explanation The add-on image download to the module failed. This module is not operational until an add-on image has been successfully installed. Recommended Action Verify the location and version of your module image. Enter install module CLI command or similar Fabric Manager/Device Manager command to download a new module image. If the image download fails, the supervisor power cycles the module. Choose Logs > Switch Resident > Syslog > Since Reboot in Device Manager or use the show logging CLI command to view the failure messages. Runtime Diagnostics After the module successfully registers with the supervisor, the module checks the hardware. If this fails, the module reports the error to the supervisor and generates the following system message: Error Message MODULE-2-MOD_DIAG_FAIL: Module [dec] reported failure on ports [dec]/[dec]-[dec]/[dec] ([chars]) due to [chars] in device [dec] (device error [hex]). Explanation The module reported a failure in the runtime diagnostic. Module manager is going to power cycle the module. Recommended Action Collect information about the module by entering the show module internal all module CLI command. In addition, this information is stored in the exception log (which is persistent across reboots). The supervisor then power cycles the module. Choose Logs > Switch Resident > Syslog > Since Reboot in Device Manager or use the show logging and show module internal exception-log module CLI commands to retrieve failure information. Runtime Configuration After the runtime diagnostics complete successfully, the module informs the supervisor that it is ready for configuration. Individual supervisor components configure the module. If any component reports a problem during this stage, the supervisor reboots the module. Use the show module internal event-history module CLI command to determine which component reported the problem. Online and Operational After all the supervisor components have configured the module, the module goes to the ok state. In this state, the module is online and operational. The supervisor continues to monitor the module periodically to verify correct operation. The following events are monitored: • Heartbeat message-Sent between the supervisor and the module to verify that the module is running. 4-24 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05
