Hardware RAID Support
The servers provide hardware RAID support through on-board SAS3 RAID controllers. Each controller enables you to create up to two logical disk volumes consisting of two or more redundant disk drives. The following table identifies the hardware RAID controllers built into each server.

Note - RAID 1e and RAID 10 are functionally equivalent. RAID 1e requires an odd number of drives (minimum three). RAID 10 requires an even number of drives (minimum four).
You can use the RAID management utilities described here with the on-board SAS3 controllers provided in these servers.
FCode-Based RAID Utility
You can use FCode-based commands provided with the on-board controller to display targets and manage logical volumes on the server. Enter these commands at the OpenBoot ok prompt.
The examples of RAID shown in this document rely on the controller's FCode-based commands, unless otherwise specified.
sas3ircu Utility
You can use the SAS3 RAID Management Utility sas3ircu at the Oracle Solaris command prompt to manage RAID functionality for the on-board SAS3 controllers. The sas3ircu utility can configure RAID 0, RAID 1, RAID 1e, and RAID 10.
Note - When you specify RAID 1e, the sas3ircu utility requires an odd number of target drives with a minimum of three. When you specify RAID 10, the utility requires an even number of target drives with a minimum of four.
The sas3ircu utility for Oracle servers and its user documentation were developed by LSI, which later became Avago Technologies/Broadcom. Download the utility and documentation from the Broadcom website at:

 | Caution - When you update firmware for the on-board SAS controllers, you must acquire the firmware from Oracle's support site (https://support.oracle.com). Firmware for the SAS controllers that is obtained from any other location or vendor is not supported. |
raidconfig Commands
You can use the raidconfig commands contained in the Oracle Hardware Management Pack. Use the Oracle Server CLI Tools component to create and manage RAID volumes on the server. See the Oracle Server CLI Tools for Oracle Solaris 11.3 User's Guide for more information about raidconfig.
If raidconfig is not available on your server, see Oracle Hardware Management Pack for Oracle Solaris 11.3 Installation Guide for installation information.
RAID Capabilities in Oracle Enterprise Manager Ops Center
You can create RAIDs and manage existing RAIDs with Oracle Enterprise Manager Ops Center. If you reconfigure an existing RAID with Oracle Enterprise Manager Ops Center, the contents of the disks in the original RAID will be lost.
