Configuring RAID

This chapter provides information about configuring RAID on your server. It contains instructions for the two supported SAS controller cards, the Sun StorageTek and the LSI SAS3081E-S. It also contains instructions for setting up a non-RAID configuration.

This chapter includes the following sections:

Configuring RAID

Creating RAID for the LSI SAS3081E-S Controller Card

Creating RAID for the Sun StorageTek Controller Card

Configuring RAID

Your server supports two RAID controller cards, the Sun StorageTek and LSI SAS3081E-S. The supported RAID configuration is different for each card (see TABLE 1-1).

RAID configuration is performed in the card’s BIOS. See the following sections for instructions on configuring RAID for each card:

LSI SAS3081E-S

If you have an LSI SAS3081E-S RAID controller and you are configuring a RAID array, see Creating RAID for the LSI SAS3081E-S Controller Card.

If you have an LSI SAS3081E-S RAID controller and you are not configuring RAID, skip this chapter.

Sun StorageTek

If you have a Sun StorageTek card, you must configure all disks, whether they are going to be part of a RAID array or not. Disks that are not going to be included in a RAID array must be configured as single-drive volumes.

See Creating RAID for the Sun StorageTek Controller Card.

Creating RAID for the LSI SAS3081E-S Controller Card

Use this section to configure RAID for the LSI SAS3081E-S controller card, by accessing the LSI BIOS utility.

Before You Begin

To create a RAID for your server, using the LSI SAA3081E-S controller card, you must have:

The LSI SAS3081E-S controller card installed in the server. For SAS controller card installation instructions, see your server service manual.

The Sun LSI 106x RAID User’s Guide. In the following procedures you will need to reference the user guide’s RAID BIOS setup instructions.

The Tools and Drivers CD.

Set up your display to access the server output (see Accessing the Server Output During Installation).

To Create a RAID for the LSI Logic SAS3081E-S Controller Card

1. Power on the server.

2. Watch the video output, and when the LSI SAS card is recognized, press Control-C to access the LSI controller card’s BIOS utility.

3. Set up the RAID according to the instructions in the Sun LSI 106x RAID User’s Guide.

4. Exit the RAID utility.

5. Install the OS you want to use.

6. Download the latest LSI utilities for managing RAID at http://www.lsi.com or from the Tools and Drivers CD under the RAIDmgmt directory.

Creating RAID for the Sun StorageTek Controller Card

This procedure provides an outline of the steps used to create a RAID array on systems with a Sun StorageTek controller using the BIOS utility.

If your system has a Sun StorageTek controller card, you must configure all disks in the system. Any drive which is not part of an array must be configured as a single-disk array, otherwise known as a volume.

Caution - In systems with Sun StoragTek controllers, you must complete the following procedure for all disks, whether they are going to be part of RAID arrays or not. The BIOS cannot access disks unless they are configured as arrays or single-disk volumes.

For detailed instructions, see the Sun Intel Adaptec BIOS RAID Utility User’s Manual and the other Sun StorageTek documentation at:

Before You Begin

To create a RAID array for your server using the Sun StorageTek controller card, you must have:

The Sun StorageTek controller card installed in the server. For controller card installation instructions, see your server service manual.

Set up your display to access the server output (see Accessing the Server Output During Installation).

To Create a RAID Array for the Sun StorageTek Controller Card

1. Power on the server.

2. Watch the video output, and when the Sun StorageTek card is recognized, press Control-A to enter the Sun StorageTek controller card’s BIOS utility.

3. Set up the RAID according to the instructions in the Sun Intel Adaptec BIOS RAID Utility User’s Manual.

4. Exit the RAID utility.

5. Install the OS.

6. Linux users must run install.sh from the Tools and Drivers CD to update to the latest RAID driver.

7. Install the latest Sun StorageTek management software located on the Tools and Drivers CD under RAIDmgmt.
