Using LSI Conguration Utility program
Use the LSI Conguration Utility program to congure and manage redundant array of independent disks
(RAID) arrays. Be sure to use this program as described in this document.
Use the LSI Conguration 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
Conguration Utility program to congure 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 controller, follow the instructions in the documentation
that comes with the adapter to view or change settings for attached devices.
When you are using the LSI Conguration Utility program to congure and manage arrays, consider the
following information:
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 plus up to two optional hot spares. 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, including up to two optional hot
spares. 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.
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.
If you use an integrated SAS/SATA controller with RAID capabilities to congure 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.
If you install a different type of RAID controller, see the documentation that comes with the controller for
information about viewing and changing settings for attached devices.
