Appendix C: Using the ARC Utility ● 69

Introduction to the ARC Utility

The ARC utility comprises these tools:

●The Array Configuration Utility (ACU)—Used to create, configure, and manage arrays, and initialize and rescan disk drives.

●SerialSelect Utility (for SAS HostRAID controllers) or SATASelect Utility (for SATA HostRAID controllers)—Used to change device and HostRAID controller settings.

●Disk Utilities—Used to format or verify disk drives (see page 76).

Running the ARC Utility

All the tools within the ARC utility are menu-based and instructions for completing tasks display on-screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on your keyboard.

To run the Utility:

1Start or restart your computer. When prompted, press Ctrl+A. The ARC utility menu displays presenting these options:

●Array Configuration Utility (ACU)

●SerialSelect or SATASelect Utility (depending on whether you are using a SAS or a SATA HostRAID controller)

●Disk utilities

To select an option from this menu, or from any of the menus within the ARC utility setup, browse with the arrow keys, then press Enter. In some cases, selecting an options displays another menu. To return to the previous menu at any time, press Esc.

Creating and Managing Arrays

Before creating arrays, make sure the disks for the array are properly connected and installed in your system. Note that disks with no usable space are shown in gray and cannot be used.

Creating a New Array

To create an array:

1Select Create Array from the main ACU menu.

Note: For more information about RAID levels and using disk drives to create arrays, see Understanding RAID on page 64.

2Select the disks for the new array, then press Insert. To deselect any disk, highlight the disk, then press Delete.

3Press Enter when all disks for the new array are selected. The Array Properties menu displays.
