the default of 2 TB, up to 8 individual 2 TB volumes will be created from
the unit.
For example, a 5 TB unit would become 3 volumes; two 2 TB volumes
and one 1 TB volume. (After creating as many volumes as possible of the
specified carvesize, any remainder will create a final volume.)
3
Verify the creation of the volumes through 3DM 2 or the CLI.
In 3DM 2, the number of volumes is shown on the Unit Details page.
4
Verify that the volumes appear in the operating system. They will appear
as additional drives.
Notes:
If you are configuring a unit for primary storage and it will be
greater than 2 TB, be sure to enable the auto-carve policy before
creating the unit.
When volumes have been created through auto-carving, they
cannot be deleted except by deleting the unit.
If you create a bootable unit that has multiple volumes, the first
volume is always used as the boot device.
Changing the auto-carve policy does not affect existing units.
To set the size of volumes created with auto-carving
Using the 3ware CLI, use the command
/cx
set carvesize
to specify
the size for volumes
The size can be between 1024Gb and 2048Gb

Setting the Auto-Rebuild Policy
For 9550SX controllers, the Auto-Rebuild policy determines how the
controller firmware will attempt to rebuild degraded units.
When Auto-Rebuild is disabled, only spares will be automatically used to
rebuild degraded units. When Auto-Rebuild is enabled, the firmware will
select drives to use for automatically rebuilding a degraded unit using the
following priority order.
Smallest usable spare.
Smallest usable unconfigured (available) drive.
Smallest usable failed drive.
