Configuring A Scsi Raid Array; Using The Lsi Logic Configuration Utility Program - IBM LS20 - BladeCenter - 8850 Installation And User Manual

The routing of an Ethernet controller to a particular I/O-module bay depends on the
type of blade server. You can verify which Ethernet controller is routed to which
I/O-module bay by using the following test:
1. Install only one Ethernet switch module or pass-thru module in I/O-module bay
2. Make sure that the ports on the switch module or pass-thru module are enabled
3. Enable only one of the Ethernet controllers on the blade server. Note the
4. Ping an external computer on the network connected to the switch module or
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.
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/servers/eserver/serverproven/compat/us/.
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
Note: You can use the ServeRAID
Important: Depending on your RAID configuration, you must create the array
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

that you enabled is associated with the switch module or pass-thru module in
I/O-module bay 1. The other Ethernet controller in the blade server is
