v
If you use an integrated SAS controller with RAID capabilities to configure a

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.
Using the LSI Logic Configuration Utility program
Use the LSI Logic Configuration Utility program to perform the following tasks:
v
Perform a low-level format of a SAS hard disk drive
v
Create an array of SAS hard disk drives with or without a hot-spare drive
v
Set SAS protocol parameters on SAS hard disk drives
The integrated SAS controller with RAID capabilities supports RAID arrays. You can
use the LSI Logic 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 SAS settings for attached devices.
The following sections provide instructions for starting the LSI Logic Configuration
Utility program and performing selected functions.
Starting the LSI Logic Configuration Utility program:
To start the LSI Logic
Configuration Utility program, complete the following steps:
1.
Turn on the computer.
2.
When the prompt
<<< Press <CTRL><C> to start LSI Logic Configuration
Utility >>>
appears, press Ctrl+C. If you have set an administrator password,
you are prompted to type the password.
3.
To select a controller (channel) from the list of adapters, use the arrow keys and
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.
When you have finished changing settings, press Esc to exit from the program;
select
Save
to save the settings that you have changed.
Formatting a SAS hard disk drive:
Low-level formatting removes all data from
the hard disk. If there is data on the disk that you want to save, back up the hard
disk before performing this procedure.
Note:
Before you format a SAS hard disk, make sure that the disk is not part of a
mirrored pair.
