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 Medium Striping and parity but uses the most physical disk characteristics over a wider range of space. IMPORTANT: RAID1 application workloads than RAID5. uses about 100% more physical disk space than RAID0 and 70% more than RAID5. RAID5 RAID5 protects against failure of one drive (and failure of particular multiple drives). RAID 50 is a nested RAID method that uses RAID 0 striping across RAID 5 arrays.
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. It is important to note that the process of rebuilding the spare or the replacement drive must not be interrupted or the process will be aborted.
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 D3000 website. 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.
4. To engage the front, pull the rail towards the front of the rack to engage the spring hook with the RETMA column in the same manner as the rear spring hook. NOTE: Make sure that the respective guide pins for the square or round hole rack align properly into RETMA column hole spacing. 5. Secure rear of rack rail to the RETMA column with either the square- or round-hole shoulder screws, provided in the plastic accessory bag. 6.
8. The rear ends of the rails have a CTO bracket that must engage with the enclosure in order to secure it to the rails. Align the CTO bracket to the corresponding rear slot into the chassis. The movable bracket can be slid forward or back to correct position. The provided screw will secure the bracket and chassis to the rail. NOTE: 9. 28 Installation The provided screw must be secured tightly. HP recommends using a T25 driver.
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 D3000 website. Disk drive guidelines CAUTION: • Follow industry-standard practices when handling disk drives.
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. IMPORTANT: drive bays.
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. Reading the “Cabling best practices” Page 32. 2. “Connecting SAS cables to the server or controller enclosure” Page 33. 3. “Connecting SAS cables to cascaded disk enclosures” Page 34. 4. “Connecting power cords” Page 35. 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, apply power to the enclosure by connecting it to a live power source. 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 sections. 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 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” Page 39.
6 Operation and management Included topics: • “Powering on disk enclosures” Page 39 • “Powering off disk enclosures” Page 39 • “Updating disk enclosure firmware” Page 39 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. Power on procedures 1. 2. Apply power to each power supply module.
To determine currently-installed firmware and software versions on system components, use management software utilities such as the HP System Management Home page, HP Systems Insight Manager (HP SIM), Storage Management Utility (SMU), or Command Line Interface (CLI). To obtain the latest-available firmware and software, see the HP website: http://www.hp.com/ support.
7 Cabling examples The following basic cabling examples are included: • “ Single-domain example” (page 42) • “Dual domain example” (page 43) IMPORTANT: The following illustrations demonstrate connecting disk enclosures to a generic host. Cabling restrictions may exist for server connect and controller enclosure connect environments. For more information, see the user documents for your controller or controller enclosure.
Single-domain example This example illustrates cabling for a single-domain configuration. In this configuration, note the following: 42 • DP1 on the disk enclosure I/O module is treated as the SAS “in” port. • DP2 on the disk enclosure I/O module is treated as the SAS “out” port. • In single-domain configurations, one cable path is created between the host, the primary disk enclosure, and additional cascaded disk enclosures.
Dual domain example This example illustrates cabling for a dual-domain configuration in a pattern that offers best possible fault tolerance. 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.
8 Troubleshooting If the enclosure does not initialize IMPORTANT: After a power failure, the system automatically returns to the On state when A/C power is restored, except in the following cases: • If both power supplies are damaged. • If there is a single power supply in the system, and it is damaged. 1. 2. 3. Ensure that power has been applied to the enclosure. Verify that the power LED is green. Verify that the power source is working: a.

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.
To minimize the likelihood of fatal system errors, take these precautions when removing failed drives: • Do not remove a degraded drive if any other drive in the array is offline (the online LED is off). In this situation, no other drive in the array can be removed without data loss. • Exceptions: • ◦ When RAID1+0 is used, drives are mirrored in pairs.
When automatic data recovery has finished, the online LED of the replacement drive stops blinking and begins to glow steadily. Failure of another drive during rebuild If a non-correctable read error occurs on another physical drive in the array during the rebuild process, the Online LED of the replacement drive stops blinking and the rebuild abnormally terminates. If this situation occurs, restart the server. The system might temporarily become operational long enough to allow recovery of unsaved data.
