3 Troubleshooting Introduction This chapter presents troubleshooting information. Basic tips for start-up problems are presented, unit status indicators are described, and general information is provided. In addition, problems that are associated with I/O functions and paths are included here. The server was tested prior to shipping and should be in perfect working order. Failures encountered during installation may be due to damage that occurred in transit. Reseating connectors may clear problems that result from rough handling. If you are installing components or assemblies, compatibility problems or incorrect installations may be the cause of problems. If you are installing components or assemblies, check that items are correctly installed and that all connectors are fully engaged. If the unit will not power on, check the power source before proceeding. Troubleshooting is based on observation of status indicators and error messages, and by checking system event logs. Status indicators can be observed on the front and rear of the server, and by removing the front bezel, top cover, and right-side panel. Error messages are displayed on local and remote consoles. System history (console, event, and history logs) are available through the management processor, and can be accessed through the console. Additional information about troubleshooting can be found in the hp Integrity rx5670 Operation and Maintenance Guide. Error Messages Most server failures will result in error messages that are displayed on the active console(s). These error messages are complete in themselves; they identify the failure and the most likely cause of the failure. If replacement of the identified part or assembly does not fix the problem, you can assume that a related part or assembly is at fault. (If replacing an I/O card does not fix a problem, replacing the corresponding driver, receiver, or interconnecting cable will usually fix the problem.) Instructions for connecting a console are provided in Chapter 4 Cable Connections under Management Processor. Management Processor The management processor (MP) records all system events. If the server malfunctions, and the cause is not obvious after inspecting status indicators and error messages, check the console, system, and event logs through the management processor. The information presented in MP logs, such as event patterns and failure-related I/O paths, will help you determine the appropriate course of action. Using the management processor is described in Chapter 4 Cable Connections under Management Processor. Additional information about the management processor can be found in the hp Integrity rx5670 Operation and Maintenance Guide. Beep Codes While beep codes have been utilized on many HP servers, beep/buzzer codes are not used by hp Integrity rx5670. Chapter 3 37
