Configuring RAID on the Server

Redundant array of independent disks (RAID) implementations provide increased performance and data integrity across the available disk space in the server. By mirroring data across drives, most RAID levels can tolerate disk failures. Additionally, RAID configurations enable you to designate one or more hot spares. A hot spare is an unused drive on which the data on a failed drive can be automatically duplicated.

RAID configuration can be done before installing the operating system, and after the operating system is installed.

  • Before you install the operating system, you can use the BIOS utilities to configure RAID. This step must be completed before installing the operating system. For details, refer to your hardware installation guide.

  • Other tools allow you to configure and modify arrays from an operating system.

    These tools should not be used to modify the disk or array where the operating system is installed.


    Caution  -  Configuring or modifying a RAID array erases all data on the disk, including the operating system. If you change the RAID configuration on a boot drive, you must reinstall the OS.

The following table lists and describes the RAID configuration:

Supported RAID Levels
BIOS Setup Utility
The BIOS Setup Utility provides various RAID configuration options. These vary according to the type of drive or HBA, and the type of RAID being installed.
Depends on the type of drive, the HBA, and the type of RAID being installed.
Refer to your server installation guide for details.
Oracle Hardware Management Pack
See Oracle Hardware Management Pack. Command-line server management tool that can be used to configure drives (except boot drives) after the operating system has been installed.
Review the output of the raidconfig list controller subcommand.
MegaRAID Command Tools
Command-line RAID configuration application that must be installed on the server after the operating system has been installed.
