some of which can only be changed in the BIOS (3BM).

firmware will attempt to rebuild degraded units.
When Auto Rebuild is disabled, only spares will be used to automatically
rebuild degraded units. When Auto Rebuild is enabled, the firmware will
automatically select drives to use for rebuilding a degraded unit using the
following priority order.
• Smallest usable spare.
• Smallest usable unconfigured (available) drive.
• Smallest usable failed drive.
For additional information, see "Setting the Auto Rebuild Policy" on page 90.
Auto-Carving. Auto-carving can be enabled or disabled by selecting the
appropriate radio button.
When this feature is enabled, any unit that is over a specified size (known as
the carve size) will be broken down into multiple volumes of that size, plus a
remainder volume. The default carve size is 2048 GB (2 TB). For example,
using the default carve size, if the unit is 2.5 TB then it will contain two
volumes, with the first volume containing 2 TB 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. 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.
Carve Size. Sets a size for dividing up units into volumes when Auto-Carving
is enabled. This setting can be between 1024 and 2048 GB.
