In addition, an LSI command-line configuration program is available from
http://www.ibm.com/servers/eserver/support/xseries/index.html/.
Consider the following information when using the LSI Configuration Utility program
to configure and manage arrays:
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 plus an optional hot
spare. 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 an optional hot spare.
– 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 disk 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 SAS
settings for attached devices.
To
start the LSI Configuration Utility program, complete the following steps:
1. Turn on the server.
2. When the message <<< Press <CTRL-C> to start LSI Configuration Utility
>>> is displayed, press Ctrl-C. If an administrator password has been set, you
are prompted to type the password.
3. Use the arrow keys to select a controller (channel) from the list of adapters;
then, press Enter.
4. To change the settings of the selected items, follow the instructions on the
screen. If you select Raid Properties, SAS Topology, or Advanced Adapter
Properties, additional screens are displayed.
See
the User’s Guide on the IBM System x Documentation CD for more information
about the LSI Configuration Utility program.
