SATA drive problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 7996," on page 11 to determine which components are CRUs and which components are FRUs. v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action The SATA drive is not recognized by the Configuration/Setup utility. 1. Reseat the SATA drive. 2. Replace the SATA drive. The operating system does not recognize the SATA drive. 1. Make sure the SATA drive is listed in the Configuration/Setup utility. 2. Run the Fixed Disk diagnostic test. 3. For information on preparing the SATA drive to install and operating system, see the documentation that comes with your operating system. 4. Reseat the SATA drive. 5. Replace the SATA drive. The blade workstation stops responding during the Fixed Disk diagnostic test. Reseat the hard disk drive that was being tested when the blade workstation stopped responding, and run the diagnostic test again. If the Fixed Disk diagnostic test fails, replace the drive that you removed with a new one. The SATA drive fails the Fixed Disk diagnostics test. 1. Reseat the SATA drive and run the Fixed Disk diagnostic test again. 2. If the Fixed Disk diagnostic test fails, replace the SATA drive. A hard disk drive passes the Run the Fixed Disk diagnostic test again. If the diagnostics continue to pass but Fixed Disk diagnostics test, but the drive continues to have a problem, replace the drive with a new one. the problem remains. Intermittent problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 7996," on page 11 to determine which components are CRUs and which components are FRUs. v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action A problem occurs only occasionally and is difficult to diagnose. 1. Make sure that: v When the blade workstation is turned on, air is flowing from the rear of the BladeCenter unit at the blower grille. If there is no airflow, the blower is not working. This causes the blade workstation to overheat and shut down. v The SATA drive is configured correctly. 2. Check the BMC log (see "POST" on page 39). Chapter 5. Diagnostics 57
