Storage Drive Configuration

Language:

Your server is equipped with an Oracle Storage 12 Gb/s SAS PCIe RAID HBA, internal. This HBA requires a RAID volume to install and boot an operating system (OS).

To prepare a drive for operating system installation:

Preinstalled Operating System: On systems with a preinstalled OS, the drives are configured at the factory. Proceed to one of the following sections:

New Operating System: 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.

Note - Drives shipped from Oracle might have a RAID 0 volume preinstalled, however it might not be bootable. Before installing on OS on it, ensure that a drive has a volume, and if you've using legacy boot mode, ensure that it is bootable.

To check the RAID configuration and to configure the drive:

To use Oracle System Assistant, see Configuring RAID Using Oracle System Assistant
To use the BIOS configuration utility, see Configuring RAID Using the BIOS RAID Configuration Utilities

The following table lists the requirements for each supported RAID level:

RAID Level	Number of Disks Required	Installation Tool
0	1	Oracle System Assistant or BIOS
1	2	Oracle System Assistant or BIOS
5	3	Oracle System Assistant or BIOS
6	3	BIOS
10	4	Oracle System Assistant or BIOS
50	6	BIOS
60	6	BIOS

Once you have created a bootable RAID volume, install the OS. For details, refer to the corresponding operating system installation guide in http://www.oracle.com/goto/X5-8/docs-videos.
