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.
9 When 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.
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.)
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.
