Additional Information for Troubleshooting a SAS/SATA drive Reseating a drive during initial set up is a valid step. If an enclosure is in production and if there are no problems other than non-detection of a drive, replace the drive that is not detected rather than reseating the drive. It is recommended not to reseat a SMART tripped or failed drive. You cannot reset a SMART tripped drive back to normal state. If a drive fails due to the controller, check if a new firmware is available to fix the issue. If a firmware update does not fix the issue, replace the drive. NOTE: If an amber blink sequence represents a SMART trip, the drive must be replaced. It cannot be fixed by a firmware update. For more information about troubleshooting a SAS/SATA drive, see the Dell PowerVault MD1000 Storage Enclosure Hardware Owner's Manual at support.dell.com/manuals. Troubleshooting Enclosure Problems Problem One of the temperature probes displays an abnormal temperature reading. Action The system management software displays four temperature probes (0-3). Probe 0 represents the temperature sensor on enclosure management module (EMM) 0. Probe 1 represents the temperature sensor on EMM1. Probe 2 and 3 are temperature sensors on the midplane. To resolve this issue: • Check for airflow obstruction. • Replace the component with the abnormal temperature sensor. NOTE: The power supplies do not have a temperature sensor that reports to the system management software. Information Update 5
