Defining rules for RAID configurations

Deployment Solution for Dell Servers

This task lets you use a graphical tool to define different RAID configuration rules. The rules are based on the number of controllers and virtual disks on the RAID.

See About configuration files

Your RAID controllers are configured according to the order that you add them in the RAID tool. This order might be different from the order that they display in the graphical representation on the Configure RAID Controllers page.

The RAID tool is supported officially only on Internet Explorer 8.

The task window graphically represents the server configuration rules that you created. The first rule that matches the RAID is applied. You can change the order of the rules with the arrow icons.

You can also perform different actions on existing rules by clicking the following icons:

  • Pencil - Edits the selected rule.

  • X - Deletes the selected rule.

  • Clipboard - Copies the selected rule.

You can access this task from the Create New Job or Task page.

See Creating a deployment task for a Dell server

To define rules for RAID configurations

  1. From the Configure RAID Controllers page, click the Add icon.

    A new icon for your rule appears in the list.

  2. Ensure that your rule is selected, and then click the pencil icon.

  3. In the RAID tool, drag one of the RAID container types into the right panel.

    You define the virtual disks that you want to create on your target server with the following RAID types:

    RAID 0

    1-32 drives.

    RAID 1

    2 mirrored drives. Can have up to two dedicated hot spares.

    RAID 5

    3-32 drives. Can have up to four dedicated hot spares.

    RAID 10

    4-16 drives. Must be an even number. Can have up to four dedicated hot spares.

    RAID 50

    6-98 drives. Must be an even number. Can have up to 16 dedicated hot spares.

    Spare (Global Hotspare)

    0-16 drives. Cannot be the first disk group. It also cannot follow a disk group that is assigned no RAID.

  4. To change the number of drives in each RAID, click the arrow icons in the right panel.

  5. (Optional) Drag another RAID type to the right panel and configure that RAID in a similar manner.

  6. To add controllers, select the Multi-controller matching option at the bottom of the left panel.

    This option displays a graphical representation of the controllers on your server and enables the Add and Remove options. It also enables the arrow icons at either side of the add and remove options. These icons let you move the pointer in the graphical representation to the controller that you want to configure.

    The text preceding these options displays how many controllers that you have currently defined.

  7. Ensure that the pointer in the graphical representation at the top of the left panel points to the controller that you want to configure.

  8. To configure additional matching controllers with this same rule, click Advanced, and select the option. Enter the text for the controller name, and then click the close icon in the top right corner.

    For example, you have one controller defined. If this option is not selected, any extra controllers are ignored and are not configured. If you enable this option, the extra controllers are configured if they match your rule.

    When this option is enabled, a blue + icon displays at the top of a controller's rule on the main Configure RAID Controllers page. You can click OK at the bottom of the RAID tool to save your progress and view the corresponding icon.

  9. To restrict this rule to servers that have the same number of controllers that you define, click Advanced at the bottom of the left panel.

    For example, you have two controllers defined. If this option is not selected, any new servers must have exactly two controllers for this rule to match. If you enable this option, the new servers must have at least two controllers for this rule to match.

    The default is to enable this option. When this option is enabled, a blue + icon displays to the left of the last controller definition on the main Configure RAID Controllers page. You can click OK at the bottom of the RAID tool to save your progress and view the corresponding icon.

  10. Click OK.
