Depending on the HBA installed in the server, you can configure hardware RAID volumes using a variety of RAID levels.
Use these resources for creating and managing the RAID resources in your server:
OSA – You can use OSA to create RAID 0 or 1 level volumes and prepare drives for OS installation. Refer to Server OS Installation, configuring RAID.
Oracle HMP – You can use the raidconfig commands contained in this software's Oracle Server CLI Tools component to create and manage RAID volumes on your server. Refer to the Oracle HMP documentation at http://www.oracle.com/goto/OHMP/docs.
LSI MegaRAID Storage Manager – You can use the MegaRAID Storage Manager graphical interface to configure and manage RAID volumes.
