Chapter 6: Creating a Bootable Array ● 43Setting the Boot ControllerNote: If your system won’t contain more than one bootable controller, skip to the next section,Creating an Array.Your ICP RAID controller supports bootable disk drives and bootable arrays. To enable yoursystem to boot from either a disk drive or an array connected to your controller:1 Enter the system setup.2 Navigate to the drive boot sequence.3 Move the boot controller to the top of the list.For more information, refer to your computer documentation.Creating an ArrayThis section explains how to create an array.A RAID 5 array is created in the examples shown in this section because RAID 5 provides themost security and best performance with a minimum of three disk drives. However, you canchoose to create an array with a different RAID level; you can also change array level later, afterthe operating system is installed.You can create an array using any of these tools:● Array Configuration Utility (ACU)—BIOS-based menus and keyboard navigation (seethe following section).● ICP Storage Manager—Graphical software application (running from a bootable RAIDinstallation CD) that you can navigate with your mouse (see page 61).● ARCCONF—Command line utility, refer to the Command Line Interface (CLI) User’sGuide.You can use either tool, but the ACU utility is the quicker and easier tool for this task.Note: ICP recommends that you not combine SAS and SATA disk drives within the same array.ICP Storage Manager generates a warning if you try to create a logical drive using acombination of SAS and SATA disk drives. See page 68 for more information.Creating an Array with the ACUThe ACU is menu-based and instructions for completing tasks appear on-screen. Menus canbe navigated using the arrows, Enter, Esc, and other keys on your keyboard.To create a RAID 5 array:1 Power on your computer. When prompted, press Ctrl+A to enter the ICP RAIDConfiguration utility.Note: During boot up, if your system has insufficient memory the following message willdisplay. “ICP RAID Configuration Utility will load after, system initialization. Please wait... Orpress Key to attempt loading the utility forcibly [Generally, not recommended]”2 If you have more than one controller of the same model or family in your computer, selectyour controller, then press Enter.3 Select Array Configuration Utility, then press Enter.
