AMCC 720-0138-00 manual Initializing Formatting and Partitioning Units

Chapter 5. Configuring Units

4In the Type field, select the RAID configuration you want.

5If stripe size applies to the RAID type you select, select a Stripe Size. (Stripe size does not apply to RAID 1.)

6Optional: In the Name box, enter a name for the unit (up to 21 characters, including dashes and underscores).

7Make changes to the unit policies, as desired. You can enable or disable the Write Cache, Auto Verify, and Continue on Source Error During Rebuild. You can also set the StorSave policy.

For details about these settings, see “Setting Unit Policies” on page 44.

8Click OK.

The new unit appears in the Unit Maintenance list at the top of the page and the operating system is notified of the new unit.

If you have auto-carving enabled and the size of your unit exceeds the carve size, you may see multiple unit volumes in your operating system. For details, see “Using Auto-Carving for Multi LUN Support” on page 32.

9When the Mac OS displays a “Disk Insertion” message, go on to “Initializing (Formatting) and Partitioning Units”, below.

Initializing (Formatting) and Partitioning Units

After you create a unit, it needs to be formatted, partitioned, and mounted by the operating system before it can be used.

Note: “Initialization” of the unit by the Mac OS is different from “initialization” of a unit by 3ware. Initialization under your operating system will format your disk, erasing any existing data in the process. Initialization under 3ware does not erase data; it puts redundant data on the drives of redundant units into a known state so that data can be recovered in the event of a disk failure. For more information, see “About Initialization” in the 3ware Serial ATA RAID Controller User Guide for the Macintosh.

When you create a unit through 3DM 2, the Mac OS X recognizes that a new disk is available, and displays a message asking what you want to do. (If this message does not appear, you can start the Disk Utility manually from the Finder and skip to step 2.)
