About Controller Policies
The following policies affect all units and drives on a controller and can be
adjusted as appropriate for your equipment. Controller policies are shown at
the bottom of the Controller Settings page in 3DM (Figure 42) and on the
Policy Control screen in 3BM (Figure 43).
•
Auto Rebuild. Determines whether the Auto Rebuild policy is enabled or
disabled. When disabled, degraded units can only be rebuilt with
designated spares. When enabled, the controller firmware will attempt to
rebuild a degraded unit if there is no spare, using either an available drive
or a failed drive.
•
Auto-Carving. Determines whether the auto-carving policy is enabled or
disabled. When it is enabled, any unit larger than a specified size (known
as the carve size) is broken into multiple volumes that can be addressed
by the operating system as separate volumes. The default carve size is 2
TB.
This auto-carving feature is sometimes referred to as multi-LUN, where
each volume that is created is referred to as a “LUN.”
Note: Throughout this documentation, the term current controller is used to refer to
the controller currently selected in this drop-down list.
Note: If you accidentally bypass display of the controller you want to
