Configuring a RAID array

Use this information to configure a RAID array.

Configuring a RAID array applies only to a compute node in which two or more hard disk drives are installed.

Note

  • When you configure a RAID array, the hard disk drives must use the same type of interface and must have identical capacity and speed.

  • If your need to replace RAID adapter, backup or record its configuration information before replacing the adapter if possible. See the documentation for your adapter for information and instructions.

You can use two hard disk drives in the compute node to implement and manage RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that are listed on the ServerProven list at the Lenovo ServerProven website. For the compute node, you must configure the RAID by using the LSI Configuration Utility program.

If an optional RAID expansion adapter is installed, you can use it to control all of the hard disk drives that are installed in the compute node. See the documentation that comes with the expansion adapter for information about how to configure the RAID array.

Important: You must create the RAID array before you install the operating system on the compute node.

You can use the LSI Logic Configuration Utility program to configure the hard disk drives and the SAS controller. To start the LSI Logic Configuration Utility, see Using the LSI Logic Configuration Utility.
