3. Enable only one of the Ethernet controllers on the blade server. Note the

If you have installed an I/O expansion card in the blade server, communications
from the expansion card are routed to I/O-module bays 3 and 4, if these bays are
supported by your BladeCenter unit type. You can verify which controller on the
card is routed to which I/O-module bay by performing the same test and using a
controller on the expansion card and a compatible switch module or pass-thru
module in I/O-module bay 3 or 4.
Configuring a SCSI RAID array
Configuring a SCSI RAID array applies to a blade server in which two SCSI hard
disk drives are installed. You can also configure a SCSI RAID array when you have
a SCSI expansion unit in which SCSI hard disk drives are installed.
Two SCSI hard disk drives in the blade server can be used to implement and
manage RAID level-1 (mirror) arrays in operating systems that are listed on the
ServerProven list at http://www.ibm.com/pc/compat/. For the blade server, you must
configure the SCSI RAID using the following programs:
v LSI Configuration Utility program
v ServeRAID Manager program
Using the LSI Logic Configuration Utility program
You can use the LSI Logic Configuration Utility program to:
v Set the SCSI device scan order
v Set the SCSI ID for the controller
Notes:
1. You can use the ServeRAID configuration programs to configure the expansion
2. The expansion unit supports RAID-1 (embedded mirroring) and RAID level-1E.
Important: Depending on your RAID configuration, you must create the array
Starting the LSI Logic Configuration Utility program
To start the LSI configuration utility program, complete the following steps:
1. Turn on the blade server (make sure that the blade server is the owner of the
