Cache module To enable faster data access from disk storage, the cache module performs two types of caching: • Posted-write caching—the controller writes user data in the cache memory on the module rather than directly to the drives. Later, when the storage system is idle, the controller writes the data to the drive array. • Read-ahead caching—the controller detects sequential array access, reads ahead into the next sequence of data, and stores the data in the read-ahead cache.
3 Basic operation Basic operating information includes: • Powering on / powering off • Updating system firmware Powering on/powering off IMPORTANT: System devices must be powered on and powered off in a specific sequence. If devices are powered on or powered off out of sequence, the server may not properly discover the storage or hard drives might be marked as failed. IMPORTANT: Because this device is part of the ExDS 9100 solution, see the ExDS 9100 administration guide for detailed instructions.

Hard drive LEDs Item Description 1 Fault/UID LED (amber/blue) 2 Online/activity LED (green) 20 LED descriptions
Table 2 LED Hard drive LED combinations Fault/UID LED (amber/blue) Interpretation On, off, or flashing Alternating amber and blue The drive has failed, or a predictive failure alert has been received for this drive; it also has been selected by a management application. On, off, or flashing Steadily blue The drive is operating normally, and it has been selected by a management application. On Amber, flashing regularly (1 Hz) A predictive failure alert has been received for this drive.
Power supply LEDs This enclosure supports hot-plug redundant power supply in a 1+1 configuration. This means that the enclosure requires one power supply to operate and the second power supply performs a redundant function.
The second character indicates the controller signalling the error: • 1—Controller 1 • 2—Controller 2 The third and fourth characters indicate the specific error on the controller: (Displayed by pressing the up or down arrow on the seven-segment display.) Example 1. Error code example C101 = Controller 1, unsupported configuration POST codes At power on, the enclosure goes through a series of tests called Power On Self Tests (POST).
Error codes Table 4 Error codes Error code Description Required action Cn01 Configuration error—Hardware not supported Log error, check hardware and cable connections. Fn00 – Fn67 Firmware error Log error, restart enclosure. If error persists, contact HP support. Hn00 – Hn29 Hardware error—Controller error Log error, contact HP support, replace controller. Hn30 Hardware error—Fatal ECC error Log error, contact HP support, replace cache module.
SAS controller LEDs Item Description Status 1 Battery LED Green solid—Healthy condition; battery fully charged Green rapid flash—Being recognized by controller; flashes flash rapidly when battery first installed and until recognized by controller Green slow flash—Discharging, cache module being powered by battery; action required Amber flashing—Fault condition 2 Controller LED Green — System activity Blinking amber — Fault condition Off — No system activity CAUTION: Do not remove a controller from the c
Power/UID module LEDs Item Description Status 1 UID button and LED Blue—Identified Off—Not identified 2 Heartbeat LED Green—Normal Off—There may be a fault or the power is off 3 System fault LED Amber—Fault condition Green—No fault condition 4 Power/Standby button and LED Green—Powered on; healthy with no fault conditions Amber—On Standby Off—No power 26 LED descriptions
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. • 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. • The system midplane and/or power button/LED assembly may need to be replaced.
Is the fan LED amber? Answers Possible reasons Possible solutions No (green) Functioning properly. No action required Yes Fan may not be inserted properly, it may have a damaged connector, or it may have failed. • Be sure that the fan is undamaged and is fully seated. • Contact an authorized service provider for assistance. Is the UID module System Status LED amber? Answers Possible reasons Possible solutions No (green) Functioning properly.
• • • • • • The The The The The The amount of I/O activity during the rebuild operation rotational speed of the hard drives availability of drive cache brand, model, and age of the drives amount of unused capacity on the drives number of drives in the array Allow approximately 5 minutes per gigabyte without any I/O activity during the rebuild process. This figure is conservative, and newer drive models usually require less time to rebuild.

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.
HP enclosures draw in cool air through the front door and expel warm air through the rear door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet. CAUTION: To prevent improper cooling and damage to the equipment, do not block the ventilation openings.
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, see the product rating label or the user documentation supplied with that option. WARNING! To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack.
as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices.
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.
