down to 120 GB. For more information, see the discussion of drive coercion
under “Creating a Hot Spare” on page 113.
Support for Over 2 Terabytes
Windows 2000, Windows XP (32-bit), Windows 2003 (32-bit and 64-bit
without SP1) and Linux 2.4 and FreeBSD 4.x, do not currently recognize unit
capacity in excess of 2 TB.
If the combined capacity of the drives to be connected to a unit exceeds 2
Terabytes (TB), you can enable auto-carving when you configure your units.
Auto-carving divides the available unit capacity into multiple chunks of 2 TB
or smaller that can be addressed by the operating systems as separate
volumes. The carve size is adjustable from 1024 GB to 2048 GB (default)
prior to unit creation.
If a unit over 2 TB was created prior to enabling the auto-carve option, its
capacity visible to the operating system will still be 2TB; no additional
capacity will be registered. To change this, the unit has to be recreated.
For more information, see “Using Auto-Carving for Multi LUN Support” on
page 92.
