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 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.
v 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.
Starting the LSI Configuration Utility program
To start the LSI Configuration Utility program, complete the following steps:
1. Turn on the server.
Note: Approximately 3 minutes after the server is connected to ac power, the
power-control button becomes active.
2. When the prompt <F1> Setup is displayed, press F1. If you have set an
administrator password, you must type the administrator password to access the
full Setup utility menu. If you do not type the administrator password, a limited
Setup utility menu is available.
Attention: If you set an administrator password and then forget it, there is no
way to change, override, or remove it. You must replace the system board.
3. Select System Settings → Adapters and UEFI drivers.
4. Select Please refresh this page first and press Enter.
5. To perform storage-management tasks, see the SAS controller documentation,
which you can download from the disk controller and RAID software matrix:
a. Go to http://www.ibm.com/systems/support/.
b. Under Product support, click System x.
c. Under Popular links, click Storage Support Matrix.
When you have finished changing settings, press Esc to exit from the program;
select Save to save the settings that you have changed.
