Your server is equipped with an Oracle Storage 12 Gb/s SAS PCIe RAID HBA, internal (7110116, 7110117). This HBA requires a RAID volume to install and boot an operating system (OS). To learn more about the HBA, see the Oracle Storage 12 Gb/s SAS PCIE RAID HBA, Internal Installation Guide at http://docs.oracle.com/cd/E52363_01/html/E52364/index.html .
To install an OS, you must ensure that the drive where you will install the OS is visible to the system. This requires that a RAID volume be created on the drive.
If you do not wish to use a RAID array, configure a drive as a RAID 0 volume.
To check the RAID configuration and to configure the drive, see Configuring RAID Using the BIOS RAID Configuration Utilities
The following table lists the requirements for each supported RAID level:
Once you have created a bootable RAID volume, install the OS. For details, refer to the corresponding operating system installation guide in https://www.oracle.com/goto/X6-2l/docs.
