Configuring a SAS RAID
Note: Configuring a SAS redundant array of independent disks (RAID) array
applies only to a blade server in which two SAS hard disk drives are installed.
You can configure a SAS RAID array for your blade server. You can use two SAS
hard disk drives in the blade server to implement and manage a RAID level-0
(striping) or RAID level-1 (mirroring) array under an operating system that is listed
at http://www.ibm.com/servers/eserver/serverproven/compat/us/. For more
information, see the Installation and User’s Guide .
If an optional BladeCenter Storage Expansion Unit 3 is installed, you can use it to
control all of the SAS hard disk drives installed in the blade server. You enable this
feature using the Configuration/Setup Utility program (see the Installation and
User’s Guide for information and instructions).
Important: You must create the RAID array before you install the operating system
on the blade server.
You can use the LSI Logic Configuration Utility program to configure the SAS hard
disk drives and SAS controller. To start the LSI Logic Configuration Utility, complete
the following steps:
1. Turn on the blade server (make sure that the blade server is the owner of the
keyboard, video, and mouse) and watch the monitor screen.
2. When the message
Press Ctrl-C to start LSI Logic Configuration Utility
appears, press F1. If an administrator password has been set, you must type
the administrator password to access the full LSI Logic Configuration Utility
menu.
3. Follow the instructions on the screen to modify the SAS hard disk drive and
SAS controller settings.
