Some devices, including Oracle Storage 12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16-Port, must include a RAID volume before they can present a valid target for OS installation programs.
The server is shipped with Oracle Storage 12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16-Port configured as RAID 0 volumes, meaning that each volume includes a single disk drive. Other volumes combine multiple disks into arrays, which can increase performance and provide redundancy.
To configure the Oracle Storage 12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16-Port see Configure RAID on Oracle Storage 12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16-Port.
Because altering RAID configuration might destroy any data or OS image on the affected drives, you should back up any data on the drive, and you should create the volume before installing an OS on it.
