The following paragraphs describe the tools and conditions required for configuring storage drives:
Preinstalled Operating System: If you plan to use a preinstalled operating system or virtual machine software, you cannot configure the server storage drives into RAID volumes because the preinstalled operating system does not support RAID configurations. In this case proceed to one of the following sections:
Type of Host Bus Adapter (HBA): Your server supports two types of SAS-2 HBAs:
Sun Storage 6 Gb SAS PCIe Internal HBA (SGX-SAS6-INT-Z): RAID is optional with this HBA.
Sun Storage 6 Gb SAS PCIe RAID Internal HBA (SGX-SAS6-R-INT-Z): This HBA requires a RAID configuration. If you do not wish to use a RAID array, you must configure a single storage drive with a RAID 0 volume (also called a "virtual disk") and make that volume bootable.
RAID Configuration Tools: You can use Oracle System Assistant (recommended) or BIOS RAID configuration utilities to configure RAID on either type of HBA.
Once you have installed your operating system, you can use supported OS-based RAID management utilities included with your server to manage RAID storage drives.
Installing a new OS: The following table lists the conditions for configuring RAID volumes when you are installing a new operating system:
