Using the LSI Configuration Utility program
Use the LSI Configuration Utility program to configure and manage redundant array
of independent disks (RAID) arrays. Be sure to use this program as described in
this document. Use the LSI Configuration Utility program to perform the following
tasks:
v Perform a low-level format on a hard disk drive
v Create an array of hard disk drives with or without a hot-spare drive
v Set protocol parameters on hard disk drives
The integrated SAS/SATA adapter with RAID capabilities supports RAID arrays. You
can use the LSI Configuration Utility program to configure RAID 1 (IM), RAID 1E
(IME), and RAID 0 (IS) for a single pair of attached devices. If you install a different
type of RAID adapter, follow the instructions in the documentation that comes with
the adapter to view or change settings for attached devices.
In addition, you can download an LSI command-line configuration program from
http://www.ibm.com/systems/support/.
When you are using the LSI Configuration Utility program to configure and manage
arrays, consider the following information:
v The integrated SAS/SATA adapter with RAID capabilities supports the following
v Hard disk drive capacities affect how you create arrays. The drives in an array
v If you use an integrated SAS/SATA adapter with RAID capabilities to configure a
v If you install a different type of RAID adapter, see the documentation that comes
Starting the LSI Configuration Utility program
To start the LSI Configuration Utility program, complete the following steps:
1. Turn on the server.

features:
– Integrated Mirroring (IM) with hot-spare support (also known as RAID 1)
Use this option to create an integrated array of two disks. All data on the
primary disk can be migrated.
– Integrated Mirroring Enhanced (IME) with hot-spare support (also known as
RAID 1E)
Use this option to create an integrated mirror enhanced array of three to eight
disks. All data on the array disks will be deleted.,
– Integrated Striping (IS) (also known as RAID 0)
Use this option to create an integrated striping array of two to eight disks. All
data on the array disks will be deleted.
can have different capacities, but the RAID adapter treats them as if they all
have the capacity of the smallest hard disk drive.
RAID 1 (mirrored) array after you have installed the operating system, you will
lose access to any data or applications that were previously stored on the
secondary drive of the mirrored pair.
with the adapter for information about viewing and changing settings for attached
devices.
Note: Approximately 20 seconds after the server is connected to AC power, the
power-control button becomes active.
