Online/activity LED (green) Fault/UID LED (amber/blue) Interpretation Off Amber, flashing regularly (1 Hz) A predictive failure alert has been received for this drive. Replace the drive as soon as possible. Off Off The drive is offline, a spare, or not configured as part of an array. NOTE: Predictive failure alerts are generated by system management software and occur only when the enclosure is connected to a Smart Array controller. The Network Storage System controller is a Smart Array controller.

5 Troubleshooting If the enclosure does not initialize If the enclosure does not initialize, check the seven-segment display for error codes. At power on, the enclosure goes through a series of Power On Self Tests (POST). As each test runs, a code is displayed on the seven-segment display, indicating the current test being run. See Seven-segment display LEDs. IMPORTANT: After a power failure or shutdown, the system automatically returns to last powered state (On or Off) when A/C power is restored. 1.
Is the system power LED amber? Answer Possible reasons Possible solutions No (green) System functioning properly. No action required Yes • The Power On/Standby button has not been pressed firmly or held long enough. • Firmly press the Power On/Standby button and hold for approximately three seconds. • The power supply may not be inserted properly, it may have a damaged connector, or it may have failed. • The system may have experienced a short. Controller firmware may be corrupted.
Is the SAS controller LED amber? Answer Possible reasons Possible solutions No (green) Functioning properly. No action required Yes • The controller has locked. • Check seven-segment display for error codes. See Chapter 4. • The controller has failed. • Other fault condition exists. • Make sure that the controller is seated properly by pressing the controller firmly into its bay after the handle has clicked in place. • Contact an authorized service provider for assistance.
• Open HP SIM or similar management software utility and inspect each physical drive in the array to confirm that no other drives have errors. • Be sure that the array has a current, valid backup. • Use replacement drives that have a capacity at least as great as that of the smallest drive in the array. The controller immediately fails drives that have insufficient capacity.
situation occurs, restart the server. The system may temporarily become operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive, replace it, and restore data from backup. Handling hard drive failures IMPORTANT: See the network storage system administration guide for detailed instructions. If the controller was configured with hardware fault tolerance, complete the following steps after a hard drive failure: 1. Determine which physical drive failed.
Troubleshooting
6 Support and other resources Rack stability Rack stability protects personnel and equipment. WARNING! To reduce the risk of personal injury or damage to equipment: • Extend leveling jacks to the floor. • Ensure that the full weight of the rack rests on the leveling jacks. • Install stabilizing feet on the rack. • In multiple-rack installations, fasten racks together securely. • Extend only one rack component at a time. Racks can become unstable if more than one component is extended.

B Rack and environmental requirements Rack planning resources The rack resource kit ships with all HP-branded or Compaq-branded 9000, 10000, and H9 Series racks. For more information on the content of each resource, see the rack resource kit documentation. If you intend to deploy and configure multiple servers in a single rack, see the white paper on high-density deployment at the HP website: http://www.hp.com/products/servers/platforms.
Space and airflow requirements To allow for servicing and adequate airflow, observe the following space and airflow requirements when deciding where to install a rack: • Leave minimum clearance of 63.5 cm (25 in) in front of the rack. • Leave minimum clearance of 76.2 cm (30 in) behind the rack. • Leave minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or row of racks. HP enclosures draw in cool air through the front door and expel warm air through the rear door.
Temperature requirements To ensure continued safe and reliable equipment operation, install or position the enclosure in a well-ventilated, climate-controlled environment. The maximum recommended ambient operating temperature (TMRA) for most enclosure products is 35°C (95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).
voltage and current rating for the cord should be greater than the voltage and current rating marked on the product. In addition, the diameter of the wire must be a minimum of 1.00 mm2 or 18 AWG, your maximum length may be up to 3.66 m (12 ft). WARNING! To reduce the risk of electric shock or damage to the equipment: • Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
C Electrostatic discharge Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers.
