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:
•
Run the diagnostics, including the service aids, certify, and format.
•
Run all the operating-system commands that are run by system group users.
•
Configure and de-configure 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 Bull Blade Chassis - Enterprise, and the operating system that is installed.
For example, each Ethernet controller on the Escala BL460 blade server system board is
routed to a different I/O module in I/O module bay 1 or module bay 2 of the Bull Blade
Chassis - Enterprise.
See "
Blade server Ethernet controller enumeration"
on page
236
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 in the same Bull Blade Chassis - Enterprise might
have different Ethernet controller routing. See the documentation 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.
