2 Installation and configuration procedures

Overview of the installation process

1. Install and configure the controller and hard drives. For details, see “Installing the controller and drives” on

page 5. The maximum supported size of the logical drive on this controller is 2 TB.

NOTE: Select drives of equal capacity and performance. Otherwise, the array tends to be limited in capacity

and performance to that of the smallest and slowest drive.

The rest of the procedure depends on whether the computer has an operating system installed.

• If the computer already has an operating system installed, go to step 4.

• Otherwise, continue with steps 2 and 3.

2. Build a bootable array, as described in “Creating a bootable array” on page 7.

3. Install the controller driver and operating system. The driver is available on the HP website

(http://www.hp.com Installation in the new server is complete.

4. Install the controller driver. The driver is available on the HP website (http://www.hp.com

for installation are given with the driver. Installation in the preconfigured server is complete.

), and instructions for installation are given with the driver.

), and instructions

Installing the controller and drives

Preparing the server

1. Back up all data on the server.

2. Close all applications.

3. Power down the server. CAUTION: In systems that use external data storage, be sure that the server is the first unit to be powered

down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up.

4. Power down all peripheral devices that are connected to the server.

5. Touch the system chassis so that you are grounded.

6. Unplug the AC power cord from the outlet and then from the server.

7. Disconnect all peripheral devices from the server.

Installing the controller board

WARNING! To reduce the risk of personal injury or damage to the equipment, consult the safety information

and user documentation provided with the server before attempting the installation. Many servers are capable of providing energy levels that are considered hazardous and are intended to be

serviced only by qualified personnel who have been trained to deal with these hazards. Do not remove enclosures or attempt to bypass any interlocks that may be provided for the purpose of removing these hazardous conditions.

1. Open the system cabinet.

2. Select an available PCI slot.

3. Remove the cover from the selected PCI slot.

4. Install the controller in the PCI slot.

5. Secure the controller bracket to the chassis.

6. Attach one end of the I2C cable to the connector on the controller board (1).

Installation and configuration procedures 5

7. Attach the other end of the I2C able to the connector on the internal drive cage backplane board (2). Figure 2-1

8. Install drives in the internal SATA drive bay of the server, if necessary. The 6-Port SATA RAID Controller can

support logical drives of up to 2 TB capacity.

NOTE: To determine the number of drives required for a particular RAID level, see page 17.

9. Use SATA cables (provided with the server or available as a separate kit) to connect the ports on the

controller to the corresponding ports on the server backplane. (To determine the location of the backplane SATA connector in a particular server model, see the server documentation.)

In HP ProLiant ML350 Generation 4p servers, use two 4x/1x SATA cables as follows:

a. Attach the 4x connector of one cable to the lower backplane port (lower four SATA drives in the cage). b. Attach the four 1x connectors (labeled P0–P3) at the other end of the cable bundle to ports 0–3 of the

controller.

c. Attach the 4x connector of the other cable to the upper backplane port. d. Attach the two connectors labeled P0 and P1 to ports 4 and 5 of the controller. e. Position cables P2 and P3 in the cable bundle from the upper backplane port so that they are out of the

way. In this server model, these two cables are inactive (they are not connected to any drives in the drive bay).

Figure 2-2

10. Close the computer cabinet.

Installation and configuration procedures 6

Assigning the boot controller

NOTE: If the server will contain two or more bootable controllers, read this section. Otherwise, omit this

section.

The 6-Port SATA RAID controller supports bootable drives and arrays. The default setting of the controller and system setup usually allows you to install and boot from either a hard drive connected to the motherboard, or from a drive or array connected to the controller.

If you already have an operating system installed on a hard drive connected to the motherboard and you want to boot a second operating system from the controller:

1. Power up the server.

The server runs the POST sequence and briefly displays an RSBU prompt.

2. At the prompt, press the F9 key to start RSBU.

3. Follow the on-screen instructions to configure the server and set the boot controller order.

4. Save the configuration, and exit from the utility.

5. Restart the server for the new settings to take effect.

For more information about using RSBU, see the HP ROM-Based Setup Utility User Guide or the server setup and installation guide. These documents are both available on the HP website, http://www.hp.com Documentation CD supplied in the server kit.

, or on the

Creating a bootable array

NOTE: If you intend to install an operating system on a drive or array connected to the controller, read this

section. Otherwise, begin installing the driver, as described on the website where the driver is located.

To create a bootable array:

1. Install the controller and drives, as described on page 5.

2. Power up the computer.

3. Press Ctrl+A to enter the RAID Configuration Utility.

The first screen shows all installed 6-Port SATA RAID controllers. If more than one controller is displayed, highlight the boot controller, and then press the Enter key.

4. Press the Enter key to select the array configuration utility.

5. Use the arrow keys to highlight Initialize Drives, and the press the Enter key.

6. Press the Insert key to highlight the drives you want to initialize, and the press the Enter key.

7. Use the arrow keys to highlight a drive that is to be used for the array, and then press the Insert key.

Repeat this step for each drive in the array. The utility displays the selected drives.

8. Press the Enter key.

A red warning box appears. This is normal.

9. Press the Y key, and then press the Enter key.

The selected drives are initialized, and then the array configuration utility main screen is displayed again.

10. Use the arrow keys to highlight Create Array, and then press the Enter key.

11. Use the arrow keys to highlight one of the previously initialized drives, and press the Insert key. Repeat this

step for each drive in the array. The 6-Port SATA RAID Controller can support logical drives up to 2 TB capacity.

12. Press the Enter key.

Installation and configuration procedures 7

13. On the next screen, respond as follows:

Table 2-1 Entries for array properties

Property line displayed Entry or selection

Array type Select the RAID level, and the press the Enter key. Array label Type a name, and then press the Enter key. Array size Press the Enter key, and then press the Enter key again to use the default granularity of GB. Stripe size Press the Enter key. Read caching Press the Enter key. Write caching Press the Enter key. Create RAID Press the Enter key. [Done] Press the Enter key.

A Creating Array window appears.

14. Press the Enter key to continue with configuration of the array. NOTE: You can start using the array immediately. However, performance is reduced until the build

process is complete.

15. Pres the Esc key until the Exit Utility window appears.

16. Highlight Yes, and then press the Enter key.

The system restarts.

The server is now ready for the driver to be installed. For details of the procedure, see the website where the driver is located.
