Introducing the AT-2973SX, AT-2973T,
and AT-2973T/4 Adapters
This chapter provides an introduction to the Allied Telesis AT-2973SX,
AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters and discusses
the following topics:
“Functional Descriptions” on page 16
“Features” on page 22

Functional Descriptions
The AT-2973SX, AT-2973T, and AT-2973T/4 Broadcom NetXtreme II
adapters are a new class of Gigabit Ethernet (GbE) converged network
interface controller (C-NIC) that can simultaneously perform accelerated
data networking and storage networking on a standard Ethernet network.
The C-NIC offers acceleration for all popular protocols used in the data
center, such as:
TCP Offload Engine (TOE) for accelerating TCP
Internet Small Computer Systems Interface (iSCSI) offload for
accelerating network storage access featuring centralized boot
functionality (iSCSI boot)
Enterprise networks that use multiple protocols and multiple network
fabrics benefit from the C-NICs ability to combine data communications,
storage, and clustering over a single Ethernet fabric by boosting server
CPU processing performance and memory utilization while alleviating I/O
bottlenecks.
The AT-2973SX adapter is set to a speed of 1000 Mbps in full duplex
mode automatically. You cannot change the speed or duplex mode of this
adapter.
The AT-2973T and AT-2973T/4 adapters include a 10/100/1000-Mbps
Ethernet MAC with both half-duplex and full-duplex capability and a 10/
100/1000-Mbps PHY. The transceiver is fully compatible with the IEEE
802.3 standard for auto-negotiation of speed.
As part of the company’s green range, all of three adapters are
engineered to reduce power consumption. They incorporate centralized
power management features that automatically place idle circuitry into a
lower power mode to save energy.
The following sections provide functional descriptions of the AT-2973SX,
AT-2973T, and AT-2973T/4 adapters:

TCP Offload
Engine (TOE)
The TCP/IP protocol suite is used to provide transport services for a wide
range of applications for the Internet, LAN, and for file transfer. The TCP
protocol is specifically designed to insure that data packets are delivered
error free and in the correct sequence from an application running a one
computer to the receiving application. The TCP protocol suite historically
has run on the host CPU, but with higher data rates, this consumes a very
high percentage of its resources while leaving little resources for the
applications. With the use of the Broadcom NetXtreme II adapter and the
TCP Offload Engine feature, the TCP/IP processing can be moved to
hardware, freeing the CPU for application processing and other higher
priority tasks .
The TCP/IP protocol suite is used to provide transport services for a wide
range of applications for the Internet, LAN, and for file transfer. Without the
TCP Offload Engine, the TCP/IP protocol suite runs on the host CPU,
consuming a very high percentage of its resources and leaving little
resources for the applications. With the use of the Broadcom NetXtreme II
Chapter 1: Introducing the AT-2973SX, AT-2973T, and AT-2973T/4 Adapters
24
adapter, the TCP/IP processing can be moved to hardware, freeing the
CPU for more important tasks such as application processing.
The Broadcom NetXtreme II adapter's TOE functionality allows
simultaneous operation of up to 1024 fully offloaded TCP connections for
1-Gbps network adapters. The TOE support on the adapter significantly
reduces the host CPU utilization while preserving the implementation of
the operating system stack.
Internet Small
Computer
Systems Interface
(iSCSI)
The IETF has standardized the Internet Small Computer Systems
Interface (iSCSI). SCSI is a popular protocol that enables systems to
communicate with storage devices, using block-level transfer (that is,
address data stored on a storage device that is not a whole file). In
addition, iSCSI maps the SCSI request and response application
protocols and its standardized command set over TCP/IP networks.
As iSCSI utilizes TCP as its sole transport protocol, it greatly benefits from
hardware acceleration of the TCP processing (that is, use of a TOE).
However, iSCSI as a Layer 5 protocol has additional mechanisms beyond
the TCP layer. iSCSI processing can also be offloaded, thereby reducing
CPU utilization even further.
The Broadcom NetXtreme II adapter targets best-system performance,
maintains system flexibility to changes, and supports current and future
OS convergence and integration. Therefore, the adapter's iSCSI offload
architecture is unique as evident by the split between hardware and host
processing.
Power
Management
When the system is down and waiting for a wake-up signal, the adapter
speed connection may be at 10 Mbps or 100 Mbps. However, it can return
to 1000 Mbps when the system is up and running if it is connected to a
1000 Mbps capable switch. For this reason, connect systems that use the
Wake on LAN (WOL) feature to a switch capable of both 1000 and 10/100
Mbps speeds.
Wake on LAN
(WOL) Feature
The WOL feature sets the speed at which the network adapter connects to
the network while the adapter is in Wake on LAN (WOL) mode which is
enabled automatically. The default speed for WOL mode is 100 Mb. An
adapter can negotiate speeds between 10 Mb and 100 Mb. You cannot
configure this feature because it is enabled automatically.
Note
The WOL feature is supported on the AT-2973T and AT-2973T/4
adapters. It is not supported on the AT-2973SX adapter. For more
information, see “Limitations” on page 66.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
25
Note
For specific systems, see your system documentation for
information about support of the WOL feature.
Adaptive
Interrupt
Frequency
The adapter driver intelligently adjusts host interrupt frequency based on
traffic conditions to increase overall application throughput. When traffic is
light, the adapter driver interrupts the host for each received packet,
minimizing latency. When traffic is heavy, the adapter issues one host
interrupt for multiple, back-to-back incoming packets, preserving host CPU
cycles.
ASIC with
Embedded RISC
Processor
The core control for Broadcom NetXtreme II adapters resides in a tightly
integrated, high-performance ASIC. The ASIC includes a RISC processor.
This functionality provides the flexibility to add new features to the card
and adapts it to future network requirements through software downloads.
This functionality also enables the adapter drivers to exploit the built-in

Overview
The AT-2973SX, AT-2973T, and AT-2973T/4 NetXtreme II Family
adapters support Preboot Execution Environment (PXE). Multi-Boot Agent
(MBA) is a software module that allows your network computer to boot
with the images provided by remote servers across the network. The
Broadcom MBA driver complies with PXE 2.1 code.
The MBA module operates in a client/server environment. A network
consists of one or more boot servers that provide boot images to multiple
computers through the network. The Broadcom implementation of the
MBA module has been tested successfully in the following environments:
Linux Red Hat PXE Server. Broadcom PXE clients are able to
remotely boot and use network resources (NFS mount, and so forth)
as well as perform Linux installations. In the case of a remote boot, the
Linux universal driver binds seamlessly with the Broadcom Universal
Network Driver Interface (UNDI) and provides a network interface in
the Linux remotely-booted client environment.
Intel APITEST. The Broadcom PXE driver passes all API compliance
test suites.
MS-DOS UNDI. The MS-DOS Universal Network Driver Interface
(UNDI) seamlessly binds with the Broadcom UNDI to provide a
network adapter driver interface specification (NDIS2) interface to the
upper layer protocol stack. This allows computers to connect to
network resources in an MS-DOS environment.
Remote Installation Service (RIS). The Broadcom PXE clients are
able to remotely boot to a Windows Server 2003 (SP1 and older)
system running RIS to initialize and install Windows Server 2003 and
prior operating systems. To extend functionalities beyond basic
network connectivity when loading an operating system through RIS,
see “Using the NetXtreme II Monolithic Driver” on page 48.
Windows Deployment Service (WDS). For Windows Server 2003
SP2, RIS was replaced by WDS, which offers a Broadcom PXE client
to install Windows operating systems, including Windows Vista,
Windows Server 2008 and Windows Server 2008 R2. To extend
functionalities beyond basic network connectivity when loading an
operating system through WDS, see “Using the NetXtreme II
Monolithic Driver” on page 48.
Automated Deployment Service (ADS). The Broadcom PXE client
can connect to a Windows Server 2003 system and run a deployment
agent that allows one to perform some administrative functions,
including, but not limited to, deploying a Windows Server 2003 image.
To extend functionalities beyond basic network connectivity when
loading an operating system through ADS, see “Using the NetXtreme
II Monolithic Driver” on page 48.

Chapter 4
Installing the Monolithic Software
Driver
A monolithic driver allows you to download an image of a PC onto an
image server and then to another PC with an adapter installed. Often,
multiple images are downloaded. The NetXtreme II Monolithic software
driver allows remote installation of an image of a PC with an AT-2973SX,
AT-2973T, or AT-2973T/4 adapter installed. This chapter describes how to
install the monolithic driver software for remote installation and discusses
the following topics:
“Using the NetXtreme II Monolithic Driver” on page 48
“Inserting the NetXtreme II Monolithic Driver in a WinPE 2.0 Image” on
page 50
“Configuring the Speed and Duplex Settings” on page 52
Chapter 4: Installing the Monolithic Software Driver
48
Using the NetXtreme II Monolithic Driver
The NetXtreme II Monolithic driver is used with a remote imaging software
such as WinPE, although it is not associated with any operating system.
Before you install a monolithic driver, you must install an AT-2973SX, AT-
2973T, or AT-2973T/4 adapter in a PC (or multiple PCs) that you want to
act as a remote node. Once you install the adapter and the monolithic
driver software, your can download the image from an image server to the
PCs with an installed adapter.
The NetXtreme II Family Adapters, based on its advanced functionalities,
uses a software architecture that includes a Virtual Bus Device (VBD) to
extend functionalities beyond basic network connectivity. However,
Microsoft, does not currently support this architecture when loading an
operating system through its Windows Deployment Services (WDS),
which was previously known as Remote Installation Services (RIS), or for
the deployment agent used in the Automated Deployment Services (ADS).
Therefore, a separate driver was created to accommodate these Microsoft
deficiencies. This driver is known as the NetXtreme II monolithic driver,
but it is sometimes referred to as the RIS driver.
The NetXtreme II monolithic driver was developed to work only for the text
mode portion of a WDS legacy installation and to establish connectivity
with a deployment agent for ADS. It is not intended to be used as a driver
loaded in the running state of an operating system. The exception to this is
the Windows Preinstallation Environment (WinPE).
For WDS, this driver is used similarly to any other network adapter driver
for supporting network connectivity after the PXE boot to the WDS server.
When placed in the I386 or AMD64 directory (depending on the version of
the operating system being deployed), the monolithic driver is called to
establish that there is driver support for the NetXtreme II Family Adapter
included in the WDS legacy image.
For ADS, the driver is placed in the PreSystem directory on the server
running ADS to establish connectivity with the deployment agent on
remote systems with NetXtreme II adapters when booting from PXE.
While Windows PE 2005 natively supports the VBD architecture, it was
found that using the minint switch in the startnet.cmd file does not. The
minint switch performs a limited scan of the system bus to identify network
devices only and, therefore, does not support the VBD architecture. Since
only network connectivity is required in Windows PE, the only supported
driver is the monolithic driver for the NetXtreme II Family adapter in this
environment as well. Place the b06nd.inf file in the INF directory within the
Windows PE image, and place the appropriate driver file (b06nd51a.sys
for x64-based builds or b06nd51.sys for x86-based builds) in the driver's
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
49
directory. If Windows PE is deployed as a flat image from a RIS or WDS
server, you must also place both the b06nd.inf and the appropriate driver
file in the I386 or AMD64 directory containing the image.
Chapter 4: Installing the Monolithic Software Driver
50
Inserting the NetXtreme II Monolithic Driver in a WinPE 2.0 Image
By default, the monolithic driver is not included in the boot.wim and
install.wim files that come with the Windows Vista, Windows Server 2008,
and Windows Server 2008 R2 Operating Systems. Microsoft's Windows
Automated Installation Kit (AIK) allows you to modify the default boot.wim
and install.wim files and create WinPE 2.0 images to include the
NetXtreme II monolithic driver in the Windows Vista, Windows Server
2008, and Windows Server 2008 R2 installation.
To insert Broadcom's NetXtreme II monolithic driver in a WinPE 2.0 image
(for Windows Vista, Windows Server 2008, and Windows Server 2008
R2), download AIK from www.microsoft.com/downloads/
Search.aspx?displaylang=en, type in “automated install kit” in the Search
field. Then install AIK.
After installing AIK, copy the latest monolithic driver to a directory on the
local hard drive of the system you installed the AIK. Follow the procedure
below to insert the monolithic driver into a WinPE 2.0 boot image.
Note
The directory structure c:\VistaPEx86 is used throughout this
procedure.
To insert the monolithic driver into a WinPE 2.0 boot image, do the
following:
1. Download the monolithic driver files, b06nd.inf and b06nd.sys.
Go to the Allied Telesis website at www.alliedtelesis.com/support/
software. After you have accessed this website, enter the model
number in the Search by Product Name box and then click Find to
view the current list of files.
2. From All Programs, open Windows AIK and select Windows PE
Tools Command prompt.
3. At the command prompt, run the copype.cmd script. The script
requires two arguments: hardware architecture and destination
location. The command syntax is:
copype.cmd <arch> <destination>
For example: copype x86 c:\VistaPEx86
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
51
4. Mount the base image to a local directory so that you can add or
remove packages by entering:
imagex /mountrw c:\VistaPEx86\winpe.wim 1
c:\VistaPEx86\mount
5. Place the monolithic driver and inf file in c:\drivers\x32\ by entering:
peimg /inf=c:\Drivers\x32\b06nd.inf
c:\VistaPEx86\mount\windows
AIK inserts the driver into the WinPE 2.0 image.
6. To complete the customization of the image, prepare the image for
deployment, enter:
peimg /prep c:\VistaPEx86\mount\windows
7. When asked to continue and have the program prepare the image for
deployment, enter:
yes
8. To commit the changes to the original image file (Winpe.wim), enter:
imagex /unmount c:\VistaPEx86\mount /commit
9. To replace the default Boot.wim file in the \ISO directory with your new
custom image, enter:
copy c:\VistaPex86\winpe.wim
c:\VistaPEx86\ISO\sources\boot.wim
Chapter 4: Installing the Monolithic Software Driver
52
Configuring the Speed and Duplex Settings
Since the typical environment where the NetXtreme II monolithic driver is
used does not provide the means to configure advanced network adapter
properties, the driver file (b06nd.inf) was modified to include a section that
allows it to be configured for a specific speed and duplex mode. This
provides a more robust connection to the network as it allows the adapter
to match the settings of its link partner (for example, a switch or a router).
To manually configure the speed and duplex, do the following:
1. Open the b06nd.inf file with a text editor like Microsoft Notepad or
WordPad.
2. Search the file for Registry parameters to locate the section that allows
you to configure the adapter speed and duplex mode.
Once located, notice the following information:
[params_utp]
hkr, , req_medium, 2, "0"
[params_fiber]
hkr, , req_medium, 2, "65283"
These are two separate sections that can be configured: one for
standard RJ-45 copper interfaces (params_utp) and one for fiber
devices (params_fiber).
3. As described in the file, replace the value above in quotation marks
under the correct section, depending upon the network adapter in your
system. The available values are shown below.
Options for copper interfaces:
– Auto (1 Gbps is enabled when that speed is
supported) = "0"
– 10 Mbps Half Duplex = "65794"
– 10 Mbps Full Duplex = "258"
– 100 Mbps Half Duplex = "66050"
– 100 Mbps Full Duplex = "514"
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide

Options for fiber interfaces:
– Auto (1 Gbps is enabled when that speed is
supported) = "0"
– 1 Gbps Full Duplex = "771"
– Auto with 1 Gbps Fallback = "33539"
– Hardware default = "65283"
The following example shows how to configure a copper interface for a
10 Mbps Full Duplex connection:

DriverName = netbeui$
BINDINGS = BXND20X
[BXND20X]
DriverName = "BXND20X$"
7. Restart the computer to complete the installation.
Note
The driver loads during system configuration and displays the
Broadcom banner, controller name, MAC address, IRQ number,
detected line speed, and the controller BusNum and DevNum. If the
driver fails to load, an initialization fail message is displayed. For
more information about the BusNum and DevNum keywords, see
“Using Keywords for the Drivers” on page 63.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
63
Using Keywords for the Drivers
The Protocol.ini file contains certain keywords that are used by the
BXND20X.dos driver. These keywords are listed below:
BusNum. Specifies the number of the PCI bus on which the network
adapter is located. This keyword requires a value ranging from 0 to
255.
DevNum. Specifies the device number assigned to the network
adapter when it is configured by the PCI BIOS. This keyword requires
a value ranging from 0 to 255.
FuncNum or PortNum. Specifies the PCI function or port number
assigned to the network controller. This keyword requires a value
ranging from 0 to 7.
Note
The BusNum, DevNum, and FuncNum (or PortNum) keywords are
needed when multiple adapters are installed in the server and when
a specific controller must be loaded in a certain order. These
keywords are used concurrently and are included for manufacturing
purposes. Do not use them unless you are familiar with how to
configure PCI devices. A PCI device scan utility is needed to find this
information.
LineSpeed. Specifies the speed of the network connection in Mbit/s.
The values are 10, 100, or 1000 Mbit/s. Technically, a line speed of
1000 Mbit/s cannot be forced and is achievable only through
auto-negotiation. For the sake of simplicity, the driver performs auto-
negotiation when the line speed is set to a value of 1000.
Duplex. Specifies the duplex mode of the network adapter. Requires a
setting of either Half or Full. When this keyword is used, the
LineSpeed keyword must also be used. If neither keyword is used, the
network adapter defaults to auto-negotiation mode.
NodeAddress. Specifies the network address used by the network
adapter. If a multicast address or a broadcast address is specified, the
adapter uses the default MAC address.
FixCheckSumOff. Turns off the driver's workaround for the TCP/IP
stack to recognize the 1s complemented version of the checksum.
AcceptAllMC. Informs the driver to deliver all multicast packets to the
upper protocol.
Chapter 5: Installing the NDIS2 Driver Software
64
See below for an example of the keywords:
[BXND20X]
DriverName = "BXND20X$"
BusNum = 3
DevNum = 14
PortNum = 2
LineSpeed = 1000
Duplex = Full
NodeAddress = 001020304050

Installing the Linux Drivers
This chapter provides procedures to install the Linux drivers for the
AT-2973SX, AT-2973T, and AT-2973T/4 adapters.
This chapter discusses the following topics:
“Overview” on page 66
“Installing Linux Driver Software” on page 68
Chapter 6: Installing the Linux Drivers
66
Overview
This chapter discusses the Linux drivers for the Broadcom NetXtreme II
network adapters and describes how to install them. For a description of
the drivers, see Table 4.
Limitations This section describes the testing limitations of the following Linux drivers:
“bnx2 Driver” on page 66
“bnx2i Driver” on page 67
bnx2 Driver
The current version of the driver has been tested on 2.4.x kernels (starting
from 2.4.24) and all 2.6.x kernels. The driver may not compile on kernels
older than 2.4.24.
Testing is concentrated on i386 and x86_64 architectures. Only limited
testing has been done on other architectures. You may need to make
minor changes to some source files and the Makefile on some kernels. In
addition, the Makefile does not compile the cnic driver on kernels older
than 2.6.16. iSCSI offload is only supported on 2.6.16 and newer kernels.
Support for the 2.4.21 kernels is provided in Red Hat Enterprise Linux 3.

Chapter 6: Installing the Linux Drivers
68
Installing Linux Driver Software
There are two ways to install the Linux driver software— from the Source
RPM Package or build the driver from the source TAR file. See the
following sections:
“Installing the Source RPM Package” on page 68
“Building the Driver from the Source TAR File” on page 70
Note
If a bnx2 or bnx2i driver is loaded and you update the Linux kernel,
you must recompile the driver module if it was installed using the
source RPM or the TAR package.
Installing the
Source RPM
Package
The procedure in this section describes how to install the Source RPM
Package. The examples in the following procedure refer to the bnx2
driver, but also apply to the bnx2i driver.
To install the Source RPM Package, do the following:
1. Enter the following command:
rpm -ivh netxtreme2-version.src.rpm
2. Change the directory to the RPM path and build the binary driver for
your kernel (the RPM path is different for each Linux distribution):
cd /usr/src/
redhat,OpenLinux,turbo,packages,rpm
...
rpm -bb SPECS/bnx2.spec
or
rpmbuild -bb SPECS/bnx2.spec (for RPM version 4.x.x)
Note
During your attempt to install a source RPM package, the following
message may be displayed: error: cannot create
%sourcedir /usr/src/redhat/SOURCES
The most likely cause of the error is that the rpm-build package has
not been installed. Locate the rpm-build package on the Linux
installation media and install it using the following command: rpm -
ivh rpm-build-version.arch.rpm
Then complete the installation of the source RPM.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
69
3. Install the newly built package which includes the driver and man
page:
rpm -ivh RPMS/i386/bnx2-
version
.arch.rpm
If you are installing over an existing distribution that may already
contain an older version of the driver, the —force option is needed.
Depending on the kernel, the driver is installed to one of the following
paths:
2.4.x kernels
/lib/modules/kernel_version/kernel/drivers/net/
bnx2.o
2.6.x kernels
/lib/modules/kernel_version/kernel/drivers/net/
bnx2.ko
For the bnx2i driver, the driver is installed on one of the following paths:
– 2.6.16 kernels and newer (bnx2 driver)
/lib/modules/kernel_version/kernel/drivers/
net/bnx2.ko
/lib/modules/kernel_version/kernel/drivers/
net/cnic.ko
– 2.6.16 kernels and newer (bnx2i driver)
/lib/modules/kernel_version/kernel/drivers/
iscsi/bnx2i.ko
4. To load the driver, enter one of the following commands:
insmod bnx2
or
modprobe bnx2
5. To load the cnic driver (if applicable), enter one of the following
commands:
insmod cnic.ko
or
modprobe cnic
Chapter 6: Installing the Linux Drivers
70
To configure the network protocol and address, refer to the documentation
provided with your operating system.
Building the
Driver from the
Source TAR File
This procedure describes how to build the bnx2 and bnx2i Linux drivers
from the Source TAR file. See the following sections:
“Building the bnx2 Driver” on page 70
“Building the bnx2i Driver” on page 71
Building the bnx2 Driver
To build the bnx2 Linux driver from the Source TAR file, do the following:
1. Create a directory and extract the TAR files to the following directory:
tar xvzf netxtreme2-
version
.tar.gz
2. Build the driver bnx2.ko (or bnx2.o) as a loadable module for the
running kernel. Enter the following commands:
cd bnx2-
version
/src
make
3. Test the driver by loading it (if necessary, first unload the existing
driver). Enter the following commands:
rmmod bnx2
insmod bnx2.o
modprobe crc32 && insmod bnx2.o
or, for Linux 2.6 kernels:
rmmod bnx2
insmod bnx2.ko
4. Load the cnic driver, if applicable. Enter the following command:
insmod cnic.ko
5. Install the driver and man page by entering the following command:
make install
Note
See the “Installing the Source RPM Package” on page 68 for the
location of the installed driver.
To configure the network protocol and address after building the driver,
refer to the manuals supplied with your operating system.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
71
Building the bnx2i Driver
To build the bnx2i Linux driver from the Source TAR file, do the following:
1. Create a directory and extract the TAR files to the directory by entering
the following command:
tar xvzf bnx2-version.tar.gz
2. Build the driver bnx2.ko as a loadable module for the running kernel by
entering the following command:
cd bnx2i-version/drivermake
3. Test the driver by loading it (if necessary, first unload the existing
driver). Enter the following commands:
rmmod bnx2i
insmod bnx2i.ko
4. Install the driver and man page, by entering:
make install
Note
See the “Installing the Source RPM Package” on page 68 for the
location of the installed driver.
5. Install the user daemon (bnx2id), by entering:
cd ${DRV_BASE}/driver
make install_usr
The make install_usr command installs the bnx2id binary under
/sbin.
To use Broadcom iSCSI, see “Load and Run Necessary iSCSI
Software Components” on page 72 to load the necessary software
components.
Chapter 6: Installing the Linux Drivers
72
Load and Run
Necessary iSCSI
Software
Components
The Broadcom iSCSI Offload software suite consists of three kernel
modules and a user daemon. To load the required software components
either manually or through system services, do the following:
1. Unload existing driver and kill the user daemon, if necessary. Do the
following:
Manual:
rmmod bnx2i
pkill -9 bnx2id
Using system service:
service bnx2id stop
2. Load the iSCSI driver and the user daemon. Do the following:
Manual:
bnx2id
insmod bnx2i.ko
or
modprobe bnx2i
Using system service:
service bnx2id start
Unloading the
Linux Driver
You can unload, or remove, the Linux Driver from an RPM or TAR
installation. See the following:
“Unloading the Driver from an RPM Installation” on page 72
“Unloading the Driver from a TAR Installation” on page 73
Unloading the Driver from an RPM Installation
This section describes how to unload, or remove, a Linux driver from an
RPM installation.
Note
The examples used in this procedure refer to the bnx2 driver, but
also apply to the bnx2i driver.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
73
Note
On 2.6 kernels, it is not necessary to bring down the eth# interfaces
before unloading the driver module.
Note
If the cnic driver is loaded, unload the cnic driver before unloading
the bnx2 driver.
Note
Before unloading the bnx2i driver, disconnect all active iSCSI
sessions to targets.
To unload the driver, use ifconfig to bring down all eth# interfaces
opened by the driver, and then enter:
rmmod bnx2
If the driver was installed using the rpm command, enter the following
command to remove it:
rpm -e netxtreme2
Unloading the Driver from a TAR Installation
If the driver was installed using make install from the tar file, manually
delete the bnx2.o or bnx2.ko driver file from the operating system. See
“Installing the Source RPM Package” on page 68 for the location of the
installed driver.
Patching PCI
Files (Optional)
This is an optional procedure that describes how to patch PCI files for
identification by other vendors.
For hardware detection utilities, such as Red Hat kudzu, to properly
identify bnx2 supported devices, you may need to update a number of files
containing PCI vendor and device information.
Note
The examples used in this procedure refer to the bnx2 driver, but
also apply to the bnx2i driver.
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
75
Setting Optional Properties for the bnx2 Driver
The disable_msi optional property can be supplied as a command line
argument to the insmod or modprobe command. The property can also be
set in the command. See the man page for more modprobe.conf
information.
All other driver settings can be queried and changed using the ethtool
utility. See the ethtool man page for more information. The ethtool
settings do not persist across a reboot or module reload. In addition, you
can put the ethtool commands in a startup script, such as
/etc/rc.local, to preserve the settings across a reboot.
Note
Some combinations of property values may conflict and result in
failures. The driver cannot detect all conflicting combinations.
This property is used to disable Message Signal Interrupts (MSI). The
property is valid only on 2.6 kernels that support MSI. This property cannot
be used on 2.4 kernels. By default, the driver enables MSI if it is supported
by the kernel. It runs an interrupt test during initialization to determine if
MSI is working. If the test passes, the driver enables MSI. Otherwise, it
uses legacy INTx mode. To set the bnx2 driver, enter one of the following:
insmod bnx2.ko disable_msi=1
or
modprobe bnx2 disable_msi=1
Setting Optional Properties for the bnx2i Driver
You can supply the optional parameters en_tcp_dack, error_mask1 and
error_mask2 as command line arguments to the insmod modprobe or
command for the bnx2i driver.
error_mask1 and error_mask2
Use “Config FW iSCSI Error Mask #" to configure certain iSCSI protocol
violations to be treated either as a warning or a fatal error. All fatal iSCSI
protocol violations result in session recovery (ERL 0). These are bit
masks. By default, all violations are treated as errors.
Caution
Do not use the error_mask parameter if you are not sure about the
consequences. Discuss these values with the Broadcom
development team on a case-by-case basis. This is a mechanism to
work around iSCSI implementation issues on the target side and
Chapter 6: Installing the Linux Drivers
76
without proper knowledge of iSCSI protocol details, users are
advised not to experiment with these parameters.
en_tcp_dack
The "Enable TCP Delayed ACK" parameter enables or disables the TCP
delayed ACK feature on offloaded iSCSI connections. The TCP delayed
ACK feature is ENABLED by default. To set the en_tcp_dack parameter in
the bnx2i driver, enter one of the following commands:
insmod bnx2i.ko en_tcp_dack=0
or
modprobe bnx2i en_tcp_dack=0
Default: ENABLED
sq_size
Use the "Configure SQ size" parameter to select the send-queue size for
offloaded connections. The SQ size determines the maximum SCSI
commands that can be queued. Also, SQ size has a bearing on the
number of connections that can be offloaded; as QP size increases, the
number of connections supported decreases. With the default values, the
AT-2973SX and AT-2973T, and AT—2973T/4 adapters can offload 28
connections.
Defaults: 128
Range: 32 to 128
Note
Broadcom validation is limited to a power of 2; for example, 32, 64,
or 128.
rq_size
Use the "Configure RQ size" parameter to choose the size of
asynchronous buffer queue size per offloaded connections. The RQ size
is not required to be greater than 16 because it is used to place iSCSI
ASYNC/NOP/REJECT messages and SCSI sense data.
Defaults: 16
Range: 16 to 32
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
77
Note
Broadcom validation is limited to a power of 2; for example, 16, 32,
or 128.
event_coal_div
The Event Coalescing Divide Factor parameter is a performance tuning
parameter used to moderate the rate of interrupt generation by the iscsi
firmware.
Defaults: 1
Valid values: 1, 2, 4, 8
bnx2i_nopout_when_commands_active
The "iSCSI NOOP even when connection is not idle" parameter enables
the offload initiator to send iSCSI NOP-OUT on wire even when the link is
not truly idle. This parameter was introduced to avoid unnecessary
session recoveries induced by some older targets when iSCSI NOP-OUT
and iSCSI CMD pdus are intermixed. Newer iSCSI target systems are
immune to this condition and this parameter is turned ON for quite some
time.
Defaults: 1
Values: Binary parameter, 0/1
The parameters can also be set in the command. See modprobe.conf
the man page for more information.
Checking the
bnx2 Driver

Teaming with
Channel Bonding
With the Linux drivers, you can team adapters together using the bonding
kernel module and a channel bonding interface. For more information, see
the Channel Bonding information in your operating system documentation.
Statistics You can view detailed statistics and configuration information using the
ethtool utility. See the ethtool man page for more information.
Linux iSCSI
Offload
This section describes how to install and run Linux iSCSI applications. The
following recommendations apply to offloading Linux iSCSI programs:
Not all Broadcom NetXtreme II adapters support iSCSI offload.
The iSCSI session will not recover after a hot remove and hot plug.
The iSCSI driver/firmware will not offload iSCSI connections onto a
jumbo frame-enabled CNIC device.
For MPIO to work properly, iSCSI nopout should be enabled on each
iSCSI session. Refer to open-iscsi documentation for procedures on
setting up noop_out_interval and noop_out_timeout values.
In the scenario where multiple CNIC devices are in the system and the
system is booted via Broadcom's iSCSI boot solution, ensure that the
iscsi node under /etc/iscsi/nodes for the boot target is bound to the NIC
that is used for booting.
See the following sections:
“Installing User Application - bnx2id” on page 83
“Installing Open iSCSI User Applications” on page 83
“Binding iSCSI Target to Broadcom NX2 iSCSI Transport Name” on
page 84

“Maximizing Offload iSCSI Connections” on page 85
AT-2973SX, AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters Installation and User’s Guide
83
Installing User Application - bnx2id
When the bnx2i RPM package is installed, install the application bnx2id
under /sbin. See “Installing the Source RPM Package” on page 68 for
information. Run the bnx2id daemon before attempting to create iSCSI
connections. The driver does not establish connections to the iSCSI target
without the daemon's assistance.
bnx2id
The bnx2id daemon requires mknod and sh shell, which are standard on
any regular server. For iSCSI boot using NetXtreme II offload support,
binaries for mknod and sh need to be bundled into an initrd image.
Installing Open iSCSI User Applications
Install and run the open-iscsi programs, iscsid and iscsiadm, from the
Broadcom distributed open-iscsi packages. See “Packaging” on page 67
for details. Before you can install the Broadcom iSCSI-supported
packages, remove all pre-installed open-iscsi packages.
To install and run the iscsid iscsiadm and programs, do the following:
1. Remove all existing open-iscsi packages.
RHEL5
rpm -e iscsi-initiator-utils
SLES10 SP1
rpm -e open-iscsi
2. Install the source RPM package by entering:
rpm -ivh <open-iscsi-package-name>.src.rpm
3. CD to the RPM path and build the binary driver for your kernel. Enter:
cd /usr/src/{redhat,OpenLinux,turbo,packages,rpm
..}
rpm -bb SPECS/<open-iscsi-package-name>.spec
or
rpmbuild -bb SPECS/<open-iscsi-package-name>.spec
(for RPM version 4.x.x)
Note
The RPM path is different for each Linux distribution.

4. Install the newly built package by entering:
rpm -ivh RPMS/<arch>/<open-iscsi-package-
name>.<arch>.rpm
where <arch> is the machine architecture such as i386.
rpm -ivh RPMS/i386/<open-iscsi-package-
name>.i386.rpm
5. Start the daemon by entering:
iscsid
Binding iSCSI Target to Broadcom NX2 iSCSI Transport Name
By default, the open-iscsi daemon connects to discovered targets using
software initiator (transport name = 'tcp'). If you want to offload an iSCSI
connection onto CNIC device should explicitly change the transport
binding of the iSCSI node. This can be done using iscsiadm cli utility as
follows:
iscsiadm --mode node --targetname iqn.2004-
06.com.broadcom:tg1 \
--portal 192.168.1.100 --op=update \
--name=node.transport_name --
value=${XPORT_NAME}
where XPORT_NAME=bcm570x-xxyyzz
xx - pci bus number of the NX2 device
yy - pci device number of the NX2 device
zz - pci function number of the NX2 device
Network interface to iscsi transport name binding can be obtained by
executing:
dmesg | grep "bnx2i: netif"
Sample output in a system with two NetXtreme II devices:
bnx2i: netif=eth1, iscsi=bcm570x-050000
bnx2i: netif=eth0, iscsi=bcm570x-030000

If you want to switch back to using the software initiator, enter the
following:
iscsiadm --mode node --targetname iqn.2004-
06.com.broadcom:tg1 \
--portal 192.168.1.100 --op=update \
--name=node.transport_name --value=tcp
Making Connections to iSCSI Targets
Refer to open-iscsi documentation for a comprehensive list of iscsiadm
commands. The following is a sample list of commands to discovery
targets and to create iscsi connections to a target:
Adding static entry
iscsiadm -m node -p <ipaddr[:port]> -T iqn.2007-
05.com.broadcom:target1 -o new
iSCSI target discovery using 'SendTargets'
iscsiadm -m discovery --type sendtargets -p
<ipaddr[:port]>
Login to target using 'iscsiadm' command
iscsiadm --mode node --targetname <iqn.targetname> --
portal <ipaddr[:port]> --login
List all drives active in the system
'fdisk -l'
Maximizing Offload iSCSI Connections
With default driver parameters set, which includes 128 outstanding
commands, bnx2i can offload a maximum of 28 iSCSI connections. This is
not a hard limit, but simple on-chip resource allocation math. The bnx2i
driver can offload > 28 connections by reducing the shared queue size
which, in turn, limits the maximum outstanding tasks on a connection. See
“Setting Values for Optional Properties” on page 74 for information on
sq_size and rq_size. The driver logs the following message to syslog when
the maximum allowed connection offload limit is reached - "bnx2i: unable
to allocate iSCSI context resources."
