Signing up to automatically receive advisories, notices, and other messages The Subscriber's Choice website includes options to register for and automatically receive, by e-mail, personalized product tips, update information, driver- and support-related advisories, and other notices for this and other HP devices. Although optional, HP recommends registering all of your HP products with Subscriber's Choice. For more information, see the Subscriber's Choice website: http:// www.hp.com/go/e-updates.
Storage planning considerations include: • • • • • • System and performance expectations Striping methods RAID levels Disk drive sizes and types Spare drives Array sizing (capacity) NOTE: For the minimum supported configuration, and other configuration information, see the QuickSpecs for the disk enclosure.
Summary Best practices Data redundancy RAID method RAID0 RAID0 is optimized for I/O speed and efficient use of physical disk capacity, but provides no data redundancy. IMPORTANT: Do not use RAID0 for LUNs if fault tolerance is required. Consider RAID0 only for noncritical storage. RAID0 LUNs provide the best performance for applications that use random I/O. None Striping RAID1 is optimized for data redundancy and I/O speed, but uses the most physical disk space.
fails at this time, the array becomes inaccessible and information stored there must be restored from backup. After the rebuild of the data onto the spare is completed, when a replacement drive is inserted to replace the failed drive, the system will automatically transfer the data from the spare onto the replacement drive and return the spare to an available-spare state.
Preparing the site Preparing your site includes: • Providing adequate structural support Calculate the total weight of your equipment and verify that your site can support the weight. For HP ProLiant server environments, consider using Rack Builder, a software tool that provides a simplified method to planning and configuring racks and rack-mountable products. Rack Builder is available on the Options tab of the ProLiant Home page of the HP servers website: http:// www.hp.com/country/us/eng/prodserv/servers.
Racking the disk enclosure The disk enclosure can be installed into most standard server racks. To verify that your rack is supported for use with the disk enclosure, see the QuickSpecs for the disk enclosure, available on the D2000 website: http://www.hp.com/go/D2000. CAUTION: Install disk drives in the enclosures only after mounting the enclosures in the rack. • A disk enclosure populated with disk drives is too heavy to lift safely.
Racking procedures 1. 2. Position left and right rack rails at the desired 'U' position in the rack, adjusting the rails to fit the rack, as needed (1). Secure rack rails to the front and back rack columns using screws. Make sure that the shoulders of the screws fit inside the square or round holes of the rack (2). NOTE: If installing rails in a square hole rack, use larger-sized shoulder screws and pins for mounting.
Installing disk drives in the enclosure Disk drive options Depending on the enclosure model, 12 or 25 disk drives can be installed in the enclosure. A variety of disk drive models are supported for use, including dual-ported and single-ported models. For more information about supported disk drives, see the QuickSpecs for the disk enclosure, available on the D2000 website: http://www.hp.com/go/D2000. Disk drive guidelines CAUTION: • Follow industry-standard practices when handling disk drives.
2. Unlatch and swing out the latch handle on the drive. Then, slide the drive into the bay (1), pressing firmly on the drive to seat it. Close the latch handle (2), pressing firmly until it locks in place. IMPORTANT: When a drive is inserted in an operational enclosure, the drive LEDs flash to indicate that the drive is seated properly and receiving power. 3. Determine the status of the hard drive (see Drive status reporting).
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: • For server connect deployments, install one or more Smart Array controllers in the server that will access the disk enclosure.
Connecting SAS cables and power cords Overview Connecting cables includes the following steps: 1. 2. 3. 4. Reading the Cabling best practices, page 35. Connecting SAS cables to the server or controller enclosure, page 36. Connecting SAS cables to cascaded disk enclosures, page 37. Connecting power cords, page 38. IMPORTANT: The following illustrations demonstrate connecting a disk enclosure to a server with an installed controller.
Connecting SAS cables to the server or controller enclosure To connect the first disk enclosure to the server or controller enclosure, use a standard mini-SAS cable. IMPORTANT: When connecting this disk enclosure in a single-domain environment, only the top I/O module (I/O module A) in the disk enclosure is supported for use. Observe the following guidelines: • Only use supported SAS cables with mini-SAS connectors.
Connecting SAS cables to cascaded disk enclosures To cascade additional disk enclosures from the disk enclosure that is connected to the server or controller enclosure, use standard mini-SAS cables. As additional disk enclosures are connected to the first disk enclosure, they are assigned a box number. The assigned box number is displayed on the 7-segment display on the rear of the disk enclosure.
Connecting power cords When connecting power cords, use the cords shipped with the disk enclosure. The power cord should be approved for use in your country. The power cord must be rated for the product and for the voltage and current marked on the electrical ratings label of the product. The 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.
Powering on the disk enclosure After disk enclosures are physically installed and cabled, power on all devices and verify that they are operating properly. Power on best practices Observe the following best practices before powering on the enclosure for the first time: • Complete the server, controller, or controller enclosure installation. For more information, see the server, controller, or controller enclosure user documents. • Install 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 the following table. 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. For more information about disk enclosure LEDs, see Chapter 1 on page 7.
5 Configuration Configuration overview Regardless of the installation environment, operating system, or software tool used to configure the disk enclosure, the following tasks must be completed: • Updating controller or controller enclosure firmware or drivers. Instructions are included with the controller or controller enclosure. • Updating disk enclosure firmware. Instructions are included with the firmware. For more information, see “Updating disk enclosure firmware” on page 44.

In this configuration, note the following: • A multi-port, dual-domain controller in the host and dual-port disk drives in the disk enclosure are required for dual-domain deployments. • Cables from each I/O module in the disk enclosure to the server or controller enclosure and to additional cascaded disk enclosures provide dual-domain connectivity.
Dual domain—alternative cabling This example illustrates cabling for a dual-domain configuration in a pattern that offers a balance of fault tolerance and performance. In this configuration, note the following: • A multi-port, dual-domain controller in the host and dual-port disk drives in the disk enclosure are required for dual-domain deployments.
8 Troubleshooting If the enclosure does not initialize IMPORTANT: After a power failure, the system automatically returns to the last-powered state (On or Off) when A/C power is restored. 1. Ensure that the power on/standby button was pressed firmly and held for approximately three seconds. 2. Verify that the power on/standby button LED is green. 3. Verify that the power source is working: a. Verify that the power supplies are working by viewing the power supply LEDs.
Is the enclosure rear fault LED amber? Answers Possible Reasons Actions No Functioning properly. No action required Yes Rear power and UID module might not be inserted properly, might have a damaged connector, or might have failed. • Be sure that the rear power and UID module is undamaged and is fully seated. • Contact an authorized service provider for assistance. Is the power on/standby button LED amber? Answer Possible Reasons Possible Solutions No System functioning properly.
Is the I/O module fault LED amber? Answer Possible Reasons Possible Solutions No Functioning properly. No action required. Yes • The I/O module is locked. • Make sure that the I/O module is seated properly by pressing the I/O module firmly into its bay after the handle has clicked in place. • The I/O module has failed. • Other fault condition exists. CAUTION: Never remove an I/O module from the chassis while the status LED is green. Removing an active I/O module can result in data loss.
Recognizing disk drive failure In an HP enclosure, a steadily glowing fault LED indicates that a disk drive has failed. Other indications of failed disk drives are as follows: • ACU represents failed drives with a distinctive icon. • HP SIM can detect failed drives remotely across a network. (For more information about HP SIM, see the documentation on the Management CD.) • ADU lists all failed drives.
• When RAID6 with ADG is used, two drives can fail simultaneously (and be replaced simultaneously) without data loss. • If the offline drive is a spare, the degraded drive can be replaced. • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the Online LED on the front of the drive stops blinking.
situation occurs, restart the server. The system might 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 disk drive failures If the controller was configured with hardware fault tolerance, complete the following steps after a disk drive failure: 1. Determine which physical drive failed. On hot-plug drives, an amber drive failure LED illuminates. 2.
