Configuring The Gigabit Ethernet Controllers - IBM power PS700 Problem Determination And Service Manual

The CE login must have a role of Run Diagnostics and be a primary group of System. This enables the
CE login to perform the following tasks:
v Run the diagnostics, including the service aids, certify, and format.
v Run all the operating-system commands that are run by system group users.
v Configure and unconfigure devices that are not in use.
In addition, this login can have Shutdown Group enabled to allow use of the Update System Microcode
service aid and the shutdown and reboot operations.
The recommended CE login user name is qserv.

Configuring the Gigabit Ethernet controllers

Two Ethernet controllers are integrated on the blade server system board. You must install a device driver
to enable the blade server operating system to address the Ethernet controllers.
Each controller provides a 1000 Mbps full-duplex interface for connecting to one of the
Ethernet-compatible I/O modules in I/O-module bays 1 and 2, which enables simultaneous transmission
and reception of data on the Ethernet local area network (LAN).
The routing from an Ethernet controller to an I/O-module bay varies, depending on the type of
BladeCenter that the blade is installed in. For example, each Ethernet controller on the system board is
routed to a different I/O module in I/O module bay 1 or module bay 2 of the BladeCenter H or HT.
See "Blade server Ethernet controller enumeration" on page 267 for information about how to determine
the routing from an Ethernet controller to an I/O-module bay for the blade server.
Note: Other types of blade servers, such as the BladeCenter HS20 Type 8678 blade server, in the same
BladeCenter unit as the PS700 blade server might have different Ethernet controller routing. See the
documentation for a blade server for information.
You must install a device driver for the blade server operating system to address the Ethernet controllers.
For device drivers and information about configuring Ethernet controllers, see the Broadcom NetXtreme
Gigabit Ethernet Software CD that comes with the blade server. For updated information about configuring
the controllers, see http://www.ibm.com/systems/support/.
The Ethernet controllers in your blade server support failover, which provides automatic redundancy for
the Ethernet controllers. Failover capabilities vary per BladeCenter unit.
Without failover, only one Ethernet controller can be connected from each server to each virtual LAN or
subnet. With failover, you can configure more than one Ethernet controller from each server to attach to
the same virtual LAN or subnet. Either one of the integrated Ethernet controllers can be configured as the
primary Ethernet controller. If you have configured the controllers for failover and the primary link fails,
the secondary controller takes over. When the primary link is restored, the Ethernet traffic switches back
to the primary Ethernet controller. See the operating-system device-driver documentation for information
about configuring for failover.
Important: To support failover on the blade server Ethernet controllers, the Ethernet switch modules in
the BladeCenter unit must have identical configurations.
