Using the ARC Utility to Create and Manage ArraysTo use the ARC utility to create and manage arrays, start the ARC utility (see Running the ARC Utility onpage 71), select your controller (if you have more than one), then press Enter. Select Logical DeviceConfiguration from the ARC main menu, then press Enter.Follow the on-screen instructions to create and manage arrays, and initialize, rescan, and erase diskdrives.Creating a New ArrayTo begin creating an array, select Create Arrays from the Logical Device Configuration menu.Only disk drives that can be used in a new array are available for selection. (Disk drives must be initializedbefore they can be used in an array. See Initializing Disk Drives on page 74 for more information.)Note:• To create a hybrid array that leverages the performance benefits of the SSDs inyour system, you must select an equal number SSDs and HDDs. You can create ahybrid RAID1 or hybrid RAID10 only.• When you create an all SSD array, we recommend disabling all caching, includingmaxCache caching. If any caching is enabled when you create the array, you willbe prompted to turn caching off.Use the Array Properties menu to modify the array's RAID level, size, name, stripe size, cache settings,and maxCache settings.Note: For more information about RAID levels and using disk drives to create arrays,see Choosing a RAID Level on page 23. For more information about maxCache, seeModifying Cache Settings on page 73.Managing Existing ArraysTo view or modify existing arrays, select Manage Arrays from the Logical Device Configuration menu.From the Manage Arrays menu, you can:• View the properties of an array.Note: Failed drives are displayed in a different text color.• Make an array bootable (see Creating Bootable Arrays on page 72).• Assign or remove hot spares.• Modify power management settings.• Change the cache settings for an array.• Delete an array.Caution: Before deleting an array, back up the data to avoid permanently losingit.Creating Bootable ArraysNote: You may need to change the system BIOS to modify the boot order. For moreinformation, refer to your computer documentation.The controller always uses the lowest numbered array as its bootable array.To make an array bootable:1. Select Manage Arrays from the Logical Device Configuration menu.2. Select the array that you want to make bootable, then press Ctrl+B.Note: You cannot make an array bootable while it's building, verifying, orrebuilding.The array's number changes to Array 00, which makes this array the controller's boot array.3. Restart your computer.72Proprietary and Confidential to PMC-Sierra, Inc.Document No.: CDP-00277-01-A Rev. A, Issue:Serial Attached SCSI RAID Controllers Installation and User's Guide
