6. SCSI Troubleshooting Troubleshooting The A5838A host bus adapter is a single field replaceable unit FRU and does not contain any field serviceable parts Troubleshooting procedures described in this section are limited to verifying that the controller is operational and a valid connection is established General Procedure 1 Check the connection Make sure that the correct cable is used connected and operating properly and that there are no bent pins in any of the connectors 2 Check SCSI bus compatibility Ensure transfer rate compatibility with the attached devices using the SCSI boot menu command 3 Check the controller Inspect the controller to make sure it is seated properly in the PCI bus slot If necessary power down the system reseat the controller and restart the system 4 Run diagnostics If a visual inspection of the controller and cable does not reveal any problems or if an action taken as a result of the inspection does not produce a working controller you may want to run diagnostics to determine whether the controller can communicate and respond to PCI bus instructions Diagnostics are described in the next section 28 Chapter 4 Troubleshooting SCSI Troubleshooting If diagnostics determine that the controller is defective you must replace it Contact your local Hewlett Packard customer representative or call the HP Response Center SCSI Bus Compatibility Use the SCSI command
