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 your operating-system
settings.
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 1.
2. Make sure that 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 that 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 that you enabled is associated with the switch module
in I/O-module bay 1. The other Ethernet controller in the blade server is associated with the
switch module in I/O-module bay 2.
If you have installed an expansion card on a blade server, communications from the option are
routed to I/O-module bays 3 and 4. You can verify which controller on the card is routed to which
I/O-module bay by performing this test, 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 an 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 drives are installed. If you installed an expansion unit with SCSI drives installed into it, those
drives can become a part of the blade server RAID array. The expansion unit supports RAID level 1
(embedded mirroring) and RAID level 1E.
Two SCSI hard disk drives in the blade server can be used to implement and manage RAID level-1
(mirror) arrays. For your blade server, you must configure the SCSI RAID using the LSI
Configuration Utility program.

Important
Depending on your RAID configuration, you must create the RAID array
before
you install the
operating system on your blade server.
