Configuring A Raid Array; Using The Lsi Logic Configuration Utility Program - IBM 7870B4U Service Manual

Configuring a RAID array

Use this information to configure a RAID array.
Configuring a RAID array applies only to a blade server in which two or more
storage drives are installed.
Note: When configuring a RAID array, the storage drives must use the same type
of interface. For example, a RAID array can be configured with two SAS storage
drives, two SATA storage drives, or two SSD storage drives.
You can use two storage drives in the blade server to implement and manage
RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that
are listed on the ServerProven
serverproven/compat/us/. For the blade server, you must configure the RAID by
using the LSI Configuration Utility program.
If an optional RAID expansion card is installed, you can use it to control all of the
storage drives that are installed in the blade server. See the documentation that
comes with the expansion card for information on how to configure the RAID
array.
Important: You must create the RAID array before you install the operating system
on the blade server.
You can use the LSI Logic Configuration Utility program to configure the storage
drives and the SAS controller. To start the LSI Logic Configuration Utility, see

"Using the LSI Logic Configuration Utility program."

Using the LSI Logic Configuration Utility program
Use these instructions to start the LSI Logic Configuration Utility program.
You can use the LSI Logic Configuration Utility program to perform the following
tasks:
v Set the SAS device scan order
v Set the SAS ID for the controller
v Manage the SAS RAID configuration
To start the LSI Logic Configuration Utility program, complete the following steps:
Note: The LSI controller on your blade server is a UEFI compatible device and can
also be configured through the Setup utility for your blade server (see
"Configuring UEFI compatible devices" on page 35).
