Appendix C: Using the Adaptec RAID Configuration Utility ● 82Introduction to the ARC UtilityThe ARC utility comprises these tools:● The Array Configuration Utility (ACU)—For creating and managing arrays, andinitializing and rescanning disk drives (see page 82).Note: Also available—ACU for DOS. See page 91.● SerialSelect—For modifying your controller and disk drive settings (see page 86).● Disk Utilities—For formatting or verifying disk drives (see page 88).Running the ARC UtilityIf your Adaptec controller is connected to a RAID enclosure, power on your enclosure (orenclosures) before you power on your computer.Start or restart your computer. When prompted, press Ctrl+A.During boot up, if your system has insufficient memory this message displays:“Adaptec RAID Configuration Utility will load after, system initialization. Please wait... Orpress Key to attempt loading the utility forcibly [Generally, not recommended]”Note: The first time you power on your computer after you install a new controller, the BIOSmay display a configuration that doesn’t match your system’s configuration. This is normal.Navigating the ARC UtilityAll the tools within the ARC utility are menu-based and instructions for completing tasksappear on-screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on yourkeyboard.Using the ACU to Create and Manage ArraysTo open the ACU, start the ARC utility (see page 82). If you have more than one controller, selectyour controller, then press Enter. Select Array Configuration Utility, then press Enter.Follow the on-screen instructions to create and manage arrays, and initialize, rescan, and erasedisk drives.Creating a New ArrayTo begin creating an array, select Create Arrays from the main ACU menu.Only disk drives that can be used in a new array are available for selection. (Disk drives must beinitialized before they can be used in an array. See Initializing Disk Drives on page 84 for moreinformation.)Use the Array Properties menu to modify the array’s RAID level, size, name, stripe size, andcaching settings.Note: For more information about RAID levels and using disk drives to create arrays, seeChoosing a RAID Level on page 31.
