Chapter 7. Configuring Your Controller
92 3ware Serial ATA RAID Controller User Guide
The main use of auto-carving is to gain use of the full capacity in units greater
than 2 TB. This is because Windows 2000, Windows 2003, Windows XP, and
FreeBSD 4.x, do not currently recognize unit capacity in excess of 2 TB.
You must turn on the Auto-Carving policy before creating the unit. Units
created with this policy turned off will not be affected by a change to the
policy. If the policy is turned off later, units that have been carved into
volumes will retain their individual volumes; existing data is not affected.
To use auto-carving
1 Enable the auto-carving feature. You can do so using 3DM or 3BM.
In 3DM, enable Auto-Carving at the bottom of the
Management >
Controller Settings
page.
In 3BM, you enable Auto-Carving on the
Settings > Controller Policies
page.

2 Create a new unit or migrate an existing unit to include the drives you
want to use.
Note: Using auto-carving can have an impact on performance.
Note: Operating systems without this limitation include Linux 2.6, FreeBSD 5.x,
Windows XP-64bit, and Windows 2003, SP 1.
Even though the Linux 2.6 kernel supports partitions larger than 2 TB, the installers
for SuSE and Redhat do not. Turn auto-carving on to prevent the installation from
failing.
