Setting the Auto Rebuild Policy
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.
Enabling Auto Rebuild allows you to add a drive to the controller and have it
be available for a rebuild, without having to specify it as a spare.
With Auto Rebuild enabled, if you accidentally disconnect a drive (causing
the controller to see it as a failed drive) and then reconnect it, the controller
will automatically try to use it again.
You can enable or disable the Auto-Rebuild policy through 3DM or 3BM.
