Unit identification (UID) button
The unit identification (UID) button helps locate an enclosure and its components. When the UID
button is activated, the UID indicators on the front and rear of the enclosure are illuminated. There
is a UID button in the front panel, and another in the rear panel of the enclosure.
NOTE: A remote session from the management utility can also illuminate the UID.
• To turn on the UID light, press the UID button. The UID light on the front and the rear of the
enclosure will illuminate solid blue.
• To turn off an illuminated UID light, press the UID button. The UID light on the front and the
rear of the enclosure will turn off.
Power supply module
Two power supplies provide the necessary operating voltages to all controller enclosure components.
If one power supply fails, the remaining power supply is capable of operating the enclosure.
(Replace any failed component as soon as possible.)

Powering on
Power is applied to the enclosure chassis upon plugging the unit into a live power source. There
is no power on/standby button.
Cables
These disk enclosures use cables with mini-SAS connectors for connections to the host and to
additional cascaded disk enclosures.
Use supported SAS cables with mini-SAS connectors. A variety of SAS cables and cable lengths
are supported for use with this disk enclosure. For more information, see the QuickSpecs for the
disk enclosure, available on the D3000 website.

3 Deployment types
The following types of deployments are supported:
• Single domain
In a single domain deployment, one path exists from the disk enclosure to the host. In a single
domain deployment, only one I/O module in the disk enclosure is used
• Dual domain
In a dual domain deployment, two paths exist from the disk enclosure to the host. In a dual
domain deployment, both I/O modules in the disk enclosure are used. Because dual domain
deployments provide two paths to the storage, access is ensured, even in the event of device,
cable, or power failure. In dual domain environments, dual-port disk drives are required.
• Server attached (single or dual domain)
In a server attached deployment, the disk enclosure is connected to a controller card installed
in a server. Several models of controller cards are supported for use with this disk enclosure.
For more information, see the QuickSpecs for the disk enclosure.
• Controller enclosure attached (single or dual domain)
In a controller enclosure attached deployment, the disk enclosure is connected to a rack-mounted
array controller enclosure. The controller enclosure is then connected to the server or network.
Several models of array controller enclosures are supported for use with this disk enclosure.
For more information, see the QuickSpecs for the disk enclosure.
NOTE: Cabling illustrations are provided elsewhere in this guide, showing a variety of example
deployments. See (page 41).

for you. For more information, see the Business & IT Services website: http://www.hp.com/go/
services.
Different levels of assistance are available. For example, the following services might be included:
• Site inspection
• Verification of operating system patch levels
• Customized virtual disk design
• Array hardware installation and activation of optional software
• Array initialization
• Verification that the implemented solution meets your specifications
• Availability of an HP Services Storage Specialist to answer questions during the deployment
process
• Verification testing to confirm product functionality and adherence to HP installation quality
standards
• On-site orientation, including highlights of basic operation and a review of documentation
Confirming support for your hardware and software components
Specific versions of hardware, firmware, software, drivers, and other components are designed
to work together.
The QuickSpecs for your disk enclosure model provide an up-to-date list of supported servers,
operating systems, controllers, switches, and software tools. Download and review the QuickSpecs
for your disk enclosure model to confirm that the components you plan to use are supported for
use with the disk enclosure.
Check the QuickSpecs before initially installing the disk enclosure and before making any changes
to an existing installation. QuickSpecs are available on the D3000 disk enclosures website.

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.
To register for and automatically receive product tips, update information, driver- and support-related
advisories, see the Subscriber's Choice website: http://www.hp.com/go/e-updates. Click Subscribe
and follow the onscreen instructions to select all of the HP products for which you want to receive
notices. While subscribing, indicate your delivery preference (HTML, text, or RSS) and frequency
of delivery (as they become available, weekly, or monthly).
Confirming warranty support and finding out about related services
The standard warranty protects against product defects and some causes of downtime. You can
extend your warranty with HP Care Pack Services. This portfolio of predefined packages is flexible,
allowing you to extend coverage to the exact level of support required. You choose the support
level that meets your business requirement, from basic to mission-critical.
Recommended service levels and appropriate related services for your particular disk enclosure
model are listed on the QuickSpecs. For more information, see the Storage Services website:
http://www8.hp.com/us/en/business-services/it-services.html?compURI=1078604.
Gathering and recording information
A brief worksheet is included on the getting started instructions that is shipped with the disk
enclosure. As you gather and identify the hardware and software components for your environment,
use the worksheet to record information about your components and your configuration. Some
information is easily obtained before installing the disk enclosure, while some of the information
is created during the configuration process.
A basic worksheet is included on the poster, but HP recommends creating and keeping more
detailed records.
Information recorded on the worksheet is used during the initial system setup and configuration,
and is helpful for future configuration changes and troubleshooting purposes.
NOTE: If a supplier is installing or configuring your disk enclosure, provide them with the poster,
and verify that they complete the worksheet and record other important configuration and set up
information.
Planning the storage configuration
Proper planning of the system storage and its subsequent performance is critical to a successful
deployment of the disk enclosure. Improper planning or implementation can result in wasted storage
space, degraded performance, or inability to expand the system to meet growing storage needs.
