  • Page 14: Temperature Requirements

    CAUTION: If a third-party rack is used, observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment: Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation).

  • Page 15: Electrical Grounding Requirements

    • Balance the enclosure power load between available AC supply branch circuits. • Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC current rating. • Do not use common power outlet strips for this equipment. •...

  • Page 16: Msa70 Shipping Contents

    WARNING! To reduce the risk of personal injury or equipment damage when unloading a rack: At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become unstable when being moved on its casters.

    • Follow industry-standard practices when handling disk drives. Internal storage media can be damaged when drives are shaken, dropped, or roughly placed on a work surface. • When installing a disk drive, press firmly to make sure the drive is fully seated in the drive bay and then close the latch handle.

  • Page 21

    Press the latch and slide it to the right to disengage the lever (1), and then open the lever (2). Make sure that the lever is in the fully opened position before inserting the drive into the bay. Slide the disk drive into the bay (1), pressing firmly on the drive to seat it. Close the lever (2), pressing firmly until it locks in place IMPORTANT: When the drive is inserted in an operational enclosure, the drive LEDs flash for 2 seconds...

  • Page 22: Installing Sas Controllers Or Controller Enclosures

    Installing SAS controllers or controller enclosures When installing controllers or controller enclosures, be sure to do the following. • Record information about the controller or controller enclosure that will connect to the disk enclosure. • Depending on your deployment, do one of the following: •...

  • Page 23: Connecting Sas Cables And Power Cords

    Connecting SAS cables and power cords After installing the enclosure in a rack, connect the SAS cables and power cords. Cabling best practices • Use the shortest possible cable between devices. Shorter cables are easier to manage and route along the back of the rack. In addition, shorter cables reduce the possibility of signal degradation that might occur over longer distances.

  • Page 24: Connecting Sas Cables To Additional Disk Enclosures

    Connecting SAS cables to additional disk enclosures To connect an additional disk enclosure to a disk enclosure that is already connected to the server or controller enclosure, use a supported SAS cable. NOTE: The left connector on the I/O module is for input from the server or controller enclosure. The right connector on the I/O module is for output to an additional enclosure.

    To protect the system from power-failure-related downtime, each disk enclosure ships standard with a redundant power supply. Depending how you connect the power supplies to the power source, you can eliminate downtime caused by power-related failures. Connection Method Level of Protection Protects you from downtime when one of the disk enclosure power Disk enclosure power supplies supplies fails.

  • Page 27: Verifying The Operating Status Of The Disk Enclosures

    Verifying the operating status of the disk enclosures To verify that the disk enclosures and disk drives are operating properly, view the enclosure and disk drive LEDs and compare them with the patterns described in Chapter 1. If LED patterns are not as expected, check cable connections between the devices, check the availability of your power source, review the installation procedures, and remove and reinsert the module.

    5 Operation and management Included topics: • Powering on disk enclosures, page 31 • Powering off disk enclosures, page 32 • Updating disk enclosure firmware, page 32 Powering on disk enclosures IMPORTANT: Always power on disk enclosures before controller enclosures and servers. This ensures that servers, during the discovery process, identify the enclosures and installed disk drives as operational devices.

  • Page 32: Powering Off Disk Enclosures

    Powering off disk enclosures IMPORTANT: Always power off disk enclosures after controller enclosures and servers. IMPORTANT: When installing a hot-pluggable component, such as a disk drive, it is not necessary to power down the enclosure. To power off a disk enclosure: Power off any attached servers.

  • Page 33: Troubleshooting

    6 Troubleshooting When the enclosure does not start If the enclosure does not power up: Verify that the server, monitor, and enclosure are plugged in. Verify that the server and monitor are working. Verify that the power source is working: Ensure that the Power On/Standby button was pressed firmly and held for approximately three seconds.

  • Page 34: Diagnostic Steps

    Diagnostic steps Are the power supply/fan module LEDs green? Possible Reasons Possible Solutions swer • Be sure that the power cord is connected to the power supply. • Be sure that the power supply is undamaged and • The power cords are not connected or is fully seated.

    • CPQONLIN identifies failed drives in a NetWare environment. For additional information about diagnosing disk drive problems, see the HP ProLiant Servers Troubleshooting Guide. CAUTION: Sometimes, a drive that has previously failed may seem to be operational after the system is power-cycled or, for a hot-pluggable drive, after the drive has been removed and reinserted.

  • Page 36: Factors To Consider Before Replacing Disk Drives

    Power up the enclosure (see Powering on disk enclosures). NOTE: In some cases, a marginal drive is operational long enough to allow backups of important files. Make copies of important data, if possible. Replace any failed drives. Read Factors to consider before replacing hard drives before replacing the failed disk drives.

    or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is likely to be permanently lost. If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error may occur, and all data on the array is then lost. In exceptional cases, however, failure of another drive need not lead to a fatal system error.

  • Page 38: Failed Drives Or Interim Recovery Mode

    Failed drives or interim recovery mode If a drive fails and hardware fault tolerance is enabled, operation continues. Do the following: Replace the drive as soon as possible. Select a logical drive. Press the F3 key to monitor to the status of drive recovery. Drive status messages include: •...

  • Page 39

    NOTE: NetWare cannot detect a single physical drive failure when using hardware-based fault tolerance. NetWare determines that the data is still valid and accessible during the rebuilding process. However, the driver knows that a physical drive has failed. A message is printed on the console notifying the user that a physical drive is in a degraded state.
