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.
v
Use the LSI Configuration Utility program to perform the following tasks:
– Perform a low-level format on a hard disk drive
– Create an array of hard disk drives with or without a hot-spare drive
– Set protocol parameters on hard disk drives
The integrated SAS/SATA controller 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
When you are using the LSI Configuration Utility program to configure and manage
arrays, consider the following information:
v
The integrated SAS/SATA controller with RAID capabilities supports the following
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.
v
Hard disk drive capacities affect how you create arrays. The drives in an array
can have different capacities, but the RAID controller treats them as if they all
have the capacity of the smallest hard disk drive.
v
If you use an integrated SAS/SATA controller with RAID capabilities to configure
a 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.
