Controller Policies and press Enter.
3 On the Policy Settings page,
Tab to the Auto-Rebuild field, press Enter

Using Auto-Carving for Multi LUN Support
When the Auto-Carving policy is on, any unit larger than a specified size
(known as the carve size) is created as multiple volumes that can be addressed
by the operating system as separate volumes. These chunks are sometimes
known as multiple LUNs (logical units). However, throughout the 3ware
documentation, they are referred to as volumes.
For example, using the default carve size of 2 TB, if the unit is 2.5 TB then it
will contain two volumes, with the first volume containing 2TB and the
second volume containing 0.5 TB. If the unit is 5.0 TB then it will contain 3
volumes, with the first two volumes containing 2 TB each and the last volume
containing 1 TB. (
Note: If a specific Boot Volume was also specified in 3BM,
the first volume will be the size specified for the Boot Volume, and then the
carve size will be applied to the remainder of the unit. For more information,
see “Boot volume size” on page 94.)
Each volume can be treated as an individual disk with its own file system. The
default carve size is 2 TB; you can change this to a setting in the range of
1TB to 2 TB (1024 GB to 2048 GB). 3ware firmware supports a maximum of
8 volumes per controller, up to a total of 16 TB.
If you are migrating a unit to a size that is larger than the carve size and auto-
carving is on, multiple volumes will be created.
