RAID configuration utilities
RAID option for the Altos R5250 system is provided through either the
onboard SATA controller or through an external daughter board
option (SAS daughter board or SAS RAID daughter board with
iButton).
Caution: Creating a RAID volume erases all data previously saved
in the hard drives. Make sure that you back up important files
before starting a RAID configuration process.
