Using Auto-Carving for Multi LUN Support

www.3ware.com 87

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 (

32-bit and 64-bit

without SP1), Windows XP (32-bit), 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 (32-bit and 64-bit with SP1 or newer).

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.
