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 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
( I/O Module Tasks > Management > Advanced 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 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, 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
Note: Configuring a SCSI RAID only applies to a blade server that has two SCSI
hard disk drives installed.
You can configure a SCSI redundant array of independent disks (RAID) array for
your blade server. Two SCSI hard disk drives in the blade server can be used to
implement and manage a RAID level-1 (mirror) array under operating systems that
are listed on the ServerProven list at http://www.ibm.com/pc/compat/. For
information about this function, see the
Installation and User’s Guide .
Important: You must create the RAID array before you install the operating system
on the blade server.
