These servers, unlike some past SPARC servers, do not provide built-in hardware RAID support. You cannot use the hardware RAID functions that were provided through FCode-based RAID utilities and commands such as create-raid1-volume.
In place of hardware RAID, consider using the ZFS capabilities provided in Oracle Solaris. For information about creating Oracle Solaris ZFS storage pools and root pools, refer to Managing ZFS File Systems in Oracle Solaris 11.3.
