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:
1 Start 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.

your system. Note that disks with no usable space are shown in gray and cannot be used.
