Creating an Array with the ARC Utility

The ARC utility is menu-based. Instructions for completing tasks appear on-screen. Menus can be 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 ARC utility.
    Note: On computers that support the Unified Extensible Firmware Interface, or uEFI, ARC utility options are presented with a uEFI/HII interface rather than the Adaptec Ctrl-A interface described below. To begin using the ARC utility with the uEFI/HII interface, see Ctrl-A or uEFI/HII?.
  2. If you have more than one controller of the same model or family in your computer, select your controller, then press Enter .
  3. Select Logical Device Configuration, then press Enter .
  4. Select Initialize Drives, then press Enter .
  5. Select at least three disk drives for the array, press Insert for each selected disk drive, then press Enter.
    During initialization, all data is deleted from the disk. Before continuing, back up any data you want to keep.
  6. Press Y , then press Enter . The selected disk drives are initialized, then the Logical Device Configuration screen appears.
  7. Select Create Array, then press Enter .
  8. Select the disk drives that were just initialized, press Insert for each selected disk drive, then press Enter .
  9. When the Array Properties screen opens, follow the instructions in the following table.
