Creating a CE login
If the blade server is running an AIX operating system, you can create a customer
engineer (CE) login to perform operating system commands that are required to
service the system without being logged in as a root user.
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 according to
the blade server type, the BladeCenter unit, and the operating system that is
installed. For example, each Ethernet controller on the JS12 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 45 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 JS12 Type 7998 blade server might have
different Ethernet controller routing. See the documentation for a blade server for
information.
You do not have to configure controllers for the blade server operating system.
However, 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.
