Blade server Ethernet controller enumeration The enumeration of the Ethernet controllers in a blade server is operating-system dependent. You can verify the Ethernet controller designations a blade server uses through the operating system settings. The routing of an Ethernet controller to a particular switch-module bay depends on the type of blade server. You can verify which Ethernet controller is routed to which switch-module bay by using the following test: 1. Install only one Ethernet switch module or pass-thru module, in switch-module bay 1. 2. Make sure the ports on the switch module or pass-thru module are enabled (Switch Tasks → Management → Advanced Switch Management in the management module Web-based user interface). 3. Enable only one of the Ethernet controllers on the blade server. Note the designation the blade server operating system has for the controller. 4. Ping an external computer on the network connected to the switch module. If you can ping the external computer, the Ethernet controller you enabled is associated with the switch module in switch-module bay 1. The other Ethernet controller in the blade server is associated with the switch module in switch-module bay 2. If you have installed an I/O expansion card on a blade server, communications from the option are routed to switch-module bays 3 and 4. You can verify which controller on the card is routed to which switch-module bay by performing the above test, using a controller on the I/O expansion card and a compatible switch module or pass-thru module in switch bay 3 or 4. Configuring an IDE RAID Note: Configuring an IDE RAID only applies to a blade server that has two IDE hard disk drives installed. You can configure an IDE redundant array of independent disks (RAID) array for the blade server. Two IDE hard disk drives in the blade server can be used to implement and manage RAID level-0 (stripe) and RAID level-1 (mirror) arrays under operating systems that are listed on the ServerProven® list at http://www.ibm.com/ pc/compat/. For information about this function, see the HS20 Type 8832 Installation and User's Guide on the BladeCenter Documentation CD or the BladeCenter T Documentation CD. Important: You must create the RAID array before you install the operating system on the blade server. 18 BladeCenter HS20 Type 8832: Hardware Maintenance Manual and Troubleshooting Guide

Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers in a blade server is operating-system
dependent. You can verify the Ethernet controller designations a blade server uses
through the operating system settings.
The routing of an Ethernet controller to a particular switch-module bay depends on
the type of blade server. You can verify which Ethernet controller is routed to which
switch-module bay by using the following test:
1.
Install only one Ethernet switch module or pass-thru module, in switch-module
bay 1.
2.
Make sure the ports on the switch module or pass-thru module are enabled
(
Switch Tasks
→
Management
→
Advanced Switch Management
in the
management module Web-based user interface).
3.
Enable only one of the Ethernet controllers on the blade server. Note the
designation the blade server operating system has for the controller.
4.
Ping an external computer on the network connected to the switch module. If
you can ping the external computer, the Ethernet controller you enabled is
associated with the switch module in switch-module bay 1. The other Ethernet
controller in the blade server is associated with the switch module in
switch-module bay 2.
If you have installed an I/O expansion card on a blade server, communications from
the option are routed to switch-module bays 3 and 4. You can verify which controller
on the card is routed to which switch-module bay by performing the above test,
using a controller on the I/O expansion card and a compatible switch module or
pass-thru module in switch bay 3 or 4.
Configuring an IDE RAID
Note:
Configuring an IDE RAID only applies to a blade server that has two IDE
hard disk drives installed.
You can configure an IDE redundant array of independent disks (RAID) array for the
blade server. Two IDE hard disk drives in the blade server can be used to
implement and manage RAID level-0 (stripe) and RAID level-1 (mirror) arrays under
operating systems that are listed on the ServerProven
®
pc/compat/. For information about this function, see the HS20 Type 8832 Installation
and User’s Guide on the
BladeCenter Documentation
CD or the
BladeCenter T
Documentation
CD.
Important:
You must create the RAID array
before
you install the operating system
on the blade server.
