Through drive coercion, the capacity used for each drive is rounded down so
that drives from differing manufacturers are more likely to be able to be used
as spares for each other. The capacity used for each drive is rounded down to
the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded
down to the nearest 5 GB for drives over 45 GB. For example, a 44.3 GB
drive will be rounded down to 44 GB, and a 123 GB drive will be rounded
down to 120 GB. For more information, see the discussion of drive coercion
under “Creating a Hot Spare” on page 42.

3ware CLI (Command Line Interface)
The 3ware CLI provides the functionality available in 3DM through a
Command Line Interface. You can view unit status and version
information and perform maintenance functions such as adding or
removing drives, and reconfiguring RAID units online. You can also use
