for Internal RAID Installation
Smart Array 6402 RAID or 6404 RAID Cards
This section provides information and instructions for installing the HP A9890A PCI-X 2-Channel RAID SA
SCSI Controller (Smart Array 6402) or the HP A9891A PCI-X 4-Channel RAID SA SCSI Controller (Smart
Array 6404).
Before installing either Smart Array card, ensure the following hardware and software prerequisites are met:
•Check the RAID-01 HP Smart Array Controller Driver Release Notes available at http://www.docs.hp.com
in the Networking & Communications section for known problems or other information needed for
installation.
• Confirm that the Smart Array 6402 or 6404 controller and software are supported on the HP Integrity
server and I/O slot chosen. Refer to the Smart Array Controller Support Matrix located at
http://www.docs.hp.com in the Networking & Communications section for more information.
• Check the HP Integrity server’s documentation to determine if additional tools are required for
component installation at http://www.docs.hp.com.
• Smart Array 6402 or 6404 controller software media is available. It is included on CD or on the Web
through http://www.software.hp.com.
• Confirm that HP-UX super-user privileges are available; they are necessary to complete the installation.
• Confirm that the /usr/bin, /usr/sbin, and /sbin directories are in your PATH by logging in as root and
using the echo $PATH command.
CAUTION Smart Array cards contain electronic components that can easily be damaged by small
amounts of electricity. To avoid damage, follow these guidelines:
• Store controllers in their anti-static plastic bags until installation.
• Work in a static-free area.
• Handle controllers by the edges only. Do not touch electronic components or electrical
traces.
• Use a grounding wrist strap.
• Use a suitable ground—any exposed metal surface on the computer chassis.
Internal and External RAID
You can use RAID cards for internal and external connections:
• Internal RAID refers to connecting embedded or internal disks to the RAID card
• External RAID refers to connecting external devices to the RAID card
SCSI Cabling Kit and Cabling Guide
In addition to the Smart Array 6402 and 6404 RAID cards, you must also have the Internal Smart Array
