set autorebuild=on|off
This command is only for 9550SX , 9590SE, and 9650SE controllers.
This command turns the Auto-Rebuild policy on or off. By default,
autorebuild is on.
autorebuild is on.
If the policy is on the firmware will select drives to use for rebuilding a
degraded unit using the following priority order.
degraded unit using the following priority order.
1. Smallest usable spare.
2. Smallest usable unconfigured (available) drive.
3. Smallest usable failed drive.
Enabling Auto-Rebuild allows you to add a drive to the controller and have it
be available for a rebuild as soon as you tell the controller to rescan, without
having to specify it as a spare. It also means that 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.

If the policy is off, spares are the only candidates for rebuild operations.

/cx set autodetect=on|off disk=<p:-p>|all
This command is only for 9000 series controllers.
This command is associated with the staggered spin-up feature when hot-
swapping drives. When staggered spin-up is enabled (see command /cx set
spinup and /cx set stagger), during a reset or power on, the controller will spin
up all detected drives with a delay between each spinup, allowing the spread
of power consumption on the power supply. When a drive is hot-swapped, (as
opposed to when it has just been powered on or reset), the default behavior of
the system is immediate spin-up. This command can change the default
behavior and set the controller to do a staggered spinup for hot-swapped
drives.

Note:
Failed drives can be drives that have mechanically failed, or they can be
drives that have been disconnected from the controller long enough for the
controller to classify them as failed.

Note:
The autodetect setting cannot be shown in CLI or displayed in 3DM or 3BM.
This feature may be added in a future release.
