Almost true..
I would suggest this procedure:

---------------------------
open afa0
controller show automatic_failover     ' to check if automatic rebuild is
activated on the controller
controller set automatic_failover /failover_enabled=TRUE     ' use this
command if the autmatic failover is disabled
enclosure show slot     ' to locate the disk to remove
enclosure prepare slot <enc> <slot>     ' use the information from the
previous command... enc=enclosure number, slot=slot number.

<replace the disk at this point!>

container list     ' you should here see that the raid is rebuilding
---------------------------

Please reply if you need more information.

Just use the Dell tool for managing your raid array, afacli, and
from in the afacli CLI program, just do a:

use afa0
enclosure prepare slot 0 #

Where # is the disk slot that needs to be removed, from 0 to 5.
Your server will power down the disk, you pop the new one
in, and it should start rebuilding on it's own.  Make sure you get
the slot number correct of course, you can check it with a
'container list' command from within afacli to make sure you have
the correct bad disk.
