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 2 (Figure 34) and on the
Policy Control screen in 3BM (Figure 35).
•
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
automatically 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, when a new unit is created, 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.”
