ATCA-S201 Overview 1
ATCA-S201 Overview
The Emerson ATCA-S201 is an ATCA carrier blade that supplies multi-protocol IP storage
services to the chassis Zone-2 backplane using Ethernet connections. The ATCA-S201
virtualizes capacity of AMC SAS/SATA disks and creates multiple logical volumes which are
mapped as iSCSI, NFS or SMB targets. Using access control lists, ATCA server blades are
given authorization to connect with virtualized volumes via 10 GbE fabric or 1GbE base
connections.
The ATCA-S201 carrier can accommodate up to four AMC disk modules. Additional disks
may be added using an Advanced ARTM which adheres to the Advanced RTM zone-3
connector pin out.
Users may also deploy the ATCA-S201 to realize gateway functions with external equipment
including SAS and/or Fiber channel (FC) storage area networks (SANs). For example,
populate with an AMC 4 Gb FC controller modules, and establish gateway services between
LUN volumes in the FC data center and the ATCA GbE network.

ATCA-S201 Installation
This chapter contains the procedures for installing and removing the ATCA-S201 10GbE RAID
storage services blade.
2.1
Installation and removal of the ATCA carrier blade
The ATCA-S201 10GbE RAID storage services blade can be installed into an ATCA
shelf (chassis) with a midplane made for front and rear board installations.
2.2
Important information about your chassis
The Chassis backplane often designates certain slots as hub slots and the others as
general purpose node slots. Be certain to select a general purpose node slot for
installation. If this installation includes a companion advanced rear transition
module (ARTM), install the ARTM first. These back-to-back slots have cut-outs that
permit the front carrier board to pass signals to the ARTM via the Zone-3 connector
complex.
Before installing the blade module, verify the module’s part number to ensure that
the correct module is being installed into the system. For information on identifying
the blade module, see Section 1.6 Part Number, Serial Number, and Address Labels.
2.3
Safety Statement
The ATCA-S201 is designed to comply with UL60950-1, and is intended to be used
with similarly tested ATCA and AMC products that have a user’s guide detailing user
installation.
2.3.1
Observe maximum module current requirements
Be sure to validate the host chassis, and the host chassis meets the maximum
current requirements.

ATCA‐S201 Installation Before you install or Remove the ATCA carrier blade
Boards may be damaged if improperly installed or handled. Please read and follow
the guidelines in this section to protect your equipment.
2.4.1
Observe ESD Precautions
Emerson strongly recommends that you use an antistatic wrist strap and a
conductive foam pad when installing or upgrading a system. Electronic
components, such as disk drives, computer boards, and memory modules, can be
extremely sensitive to electrostatic discharge (ESD). After removing the component
from its protective wrapper or from the system, place the component flat on a
grounded, static-free surface (and, in the case of a board, component side up). Do
not slide the component over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by
wearing an antistatic wrist strap (available at electronics stores) that is attached to
an active electrical ground. Note that a system chassis may not be grounded if it is
unplugged.
2.4.2
Watch for Bent Pins or Other Damage
Bent pins or loose components can cause damage to the board, the backplane, or
other system components. Carefully inspect your board and the backplane for both
pin and component integrity before installation. Our suppliers take significant steps
to ensure there are no bent pins on the backplane or connector damage to the
boards prior to leaving our factory. Bent pins caused by improper installation or by
boards with damaged connectors could void the warranty for the backplane or
boards.
If a system contains one or more crushed pins, power off the system and contact
your local sales representative to schedule delivery of a replacement chassis
assembly.
2.5
Use Caution When installing or removing the ATCA carrier
When installing boards in an empty chassis, we recommend that you start
at the left of the card cage and work to the right. This helps to avoid mistakes in
matching slots with the intended carrier boards.
When inserting or removing a board in a slot adjacent to other boards, use extra
caution to avoid damage to the pins and components located on the primary or
secondary sides of the boards.
2.5.1
Preserve EMI Compliance
To preserve compliance with applicable standards and regulations for
electromagnetic interference (EMI), during operation all front and rear openings on
6806800H62B ATCA‐S201 Installation and Use Guide 15 ATCA‐S201 Installation the chassis or board faceplates must be filled with an appropriate card or covered
with a filler panel. If the EMI barrier is open, devices may cause or be susceptible to
excessive interference.
2.5.2
Understand Hot Swap
The ATCA module is electrically designed for hot swap within a fully powered
chassis. To facilitate hot swap, there is a blue LED on the front faceplate. This LED is
under software control of the IPMC managers.
The manager will illuminate the blue hot swap LED on the front faceplate when
software has stopped and it is safe to remove the advanced rear transition module.
If the blue-LED is not illuminated or blinking, it is not ready for removal. Powering
down or removing a board before the operating system or other software running
on the board has been properly shut down may cause corruption of data or file
systems.
2.6
Connector Mechanical keying
The ATCA supports mechanical connector keying to help prevent installation with
incompatible components and RTM. The ATCA carrier board utilizes an A1/K1 key
that is set at for universal)
2.7
Verify Slot Usage
Prevent possible damage to module components by verifying the proper slot usage
for your configuration.
In most cases, electronic keying (E-keying) will prevent power on of a board into an
incompatible slot. However, as an extra precaution, you should be familiar with the
slot purpose.
2.8
Installing the ATCA carrier blade
This section describes a recommended procedure for installing the ATCA carrier
module in a chassis.
Before you install your module, please read all cautions, warnings, and instructions
presented in this section.
Handling modules and peripherals can result in static damage. Use a grounded wrist
strap, static-dissipating work surface, and antistatic containers when handling and
storing components.
Insert the board by holding the Module Handles–do not exert unnecessary pressure
on the faceplate.
Hot swap compliant modules may be installed while the system is powered on. If a
module is not hot swap compliant, you should remove power to the slot or system
before installing the module.

ATCA‐S201 Installation Power on the system, if necessary. Refer to your system manual for instructions
on correctly powering on the system. Once power is applied to the chassis, the
internal MMC controller runs a self-test that runs for approximately 10 seconds.
Upon a successful power up self-test, the blue hot swap LED will blink and then
turn off, indicating that the module has been placed in operation.
Removing the ATCA carrier blade
The ATCA-S201 ATCA carrier blade is hot-swappable and can be removed from a
powered chassis. This section describes a recommended procedure for removing a
board module from a chassis.
Before you remove your module, please read all cautions, warnings, and instructions
presented in this section. Hot swap compliant modules may be removed while the
system is powered on. When the lower ejector handle is partially disengaged, a
mechanical switch will assert a signal to notify the IPMC to begin removal
preparations. The IPMC will blink the blue hot-swap LED as it transitions the module
to the appropriate power-down state. Upon completion and with permission from
the ShMC, The blue LED will illuminate steady ON. This is the only indication that
safe removal may commence. If the Blue LED is blinking or off, it is not ready for hot
plug.
To remove the ATCA module, follow these steps:
1.
Loosen the locking screws on the rear transition module.
2.
Rotate the lower ejector handle to the half way (HW) position. Do not remove
the module immediately.
3.
If your host module running hot swap-aware software, the action of rotating
the ejector lever will start the shutdown process on the board. The software will
slowly blink the blue hot swap LED indicating the module is in the process of
being de-activated.
4.
Once the module has been de-activated, the Blue LED will illuminate steady.
Once this is done you can extract the module by pulling on the module handle.
Note: Powering down or removing a board before the operating system or
other software running on the board has been properly shut down may cause
corruption of data or file systems.
5.
When the blue LED is illuminated ON, removal of the ATCA carrier board may
proceed.
6.
Carefully pull the module from the chassis.
7.
If the card slot is to remain empty, install a filler panel in the slot.
2.10 Verifying the Hardware Installation
This section provides information to verify the installation of the ATCA-S201 10 GbE
RAID storage services module.
6806800H62B ATCA‐S201 Installation and Use Guide 18 ATCA‐S201 Installation 2.10.1 To Verify the Hardware Installation
1.
After power is applied to the system, wait approximately 45 seconds for
firmware to initialize the board.
2.
Inspect the LEDs on the front of the ATCA panel. When properly installed and
powered, the LEDs will illuminate as follows:
 ATCA Hot Swap LED
Off: Normal, default state
 ATCA Health status
Green-blinking: Healthy, OK
 ATCA Out of service (OOS)
Off: Normal, default state
3.
(Optional). There are five Ethernet ports on the ATCA blade:
 1 management (on RTM)
 2 ATCA base ports (zone-2 connector)
 2 ATCA fabric ports (zone-2 connector)
If DHCP is running on the network, it is possible to immediately ping the
Ethernet ports on the ATCA module. Open a command line window on any
node, and attempt to ping the ATCA blade.
ok ping 192.168.1.xxx
Note1: Ping requires that you determine the IP address assigned to the blade. The
carrier blades MAC address assignments are registered with the IANA public section
of the IEEE Standards OUI (Organizational unique identifier) database. The Ethernet
ports for the blade can be identified by finding the IP address corresponding to the
following MAC address assignments:

This chapter describes how to establish management communications with the ATCA-S201
for purposes including initial configuration, administration and monitoring the storage
services. A typical ATCA deployment will consist of an ATCA chassis, ATCA carrier blades,
Advanced RTM and shelf management controllers (ShMC). Administrators may choose from
the following physical access ports to conduct management communications:
 Full configuration capabilities:
- RS232 on Advanced Rear transition module (ARTM)
- Ethernet on Advanced Rear transition module (1 GbE on ARTM)
- Any zone 2 Ethernet connection (base or fabric)
In addition to DHCP, the ARTM Ethernet port offers special protocol services such as TFTP to
recover corrupted flash or accidental erasure. All available management communications
methods are outlined in this chapter.

RS232 Console port
This port is implemented on an RJ45 connector located on the ARTM that supplies
RS232 console port access. As the ATCA-S201 boots, its progress can be monitored
on the console.
By default, this port is set for VT100 terminal emulation as listed in the table below.

A serial interface can be established using a null modem cable and virtually any
terminal communications tool. If using a PC running Microsoft® Windows®, the
user may use HyperTerminal. On Linux-based systems, Minicom can be used.
Note: Use U-boot to adjust the default baud rate below the maximum 115200 if
desired.
3.1.1
System boot overview
The ATCA-S201 is designed to boot and become ready for management logins
without any user intervention. This is possible only if the supporting network offers
DHCP. The ATCA-S201 requires no disk drives for initialization. At manufacturing
time, two duplicate copies of firmware code are pre-loaded on non-volatile flash
components embedded on the carrier board. These firmware images include Uboot, a Linux kernel, and the root file system (rfs) which contains the storage
application services. On power-up or reset, the blade inspects jumper positions to
decide whether firmware is fetched from the customer flash or a read-only factory
flash. This feature allows blade recovery in situations where the customer flash has
been accidently erased or corrupted. The blade boot sequence continues as the
onboard CPU loads firmware and executes the code contents. If no attempts are
made to halt or suspend the boot process, approximately 45 seconds later, the
module is able to accept management communication logins and commands. Once
booted, the blade runs entirely out of DDR2 SRAM embedded on the blade. All
Ethernet ports are configured for DHCP. If DHCP is not used on your network, the
ATCA-S201 Ethernet ports must be initialized manually as described in section 3.6 of
this manual.

Linux serial console shell window
If the boot is not interrupted and has completed, the RS232 port accepts
administrator login for Linux shell access, and access to command line configuration
tools.
After successful login, the user may run any of the command line configuration tools
presented in section 3.4.5.
3.2
Default blade login accounts and passwords
The ATCA-S201 includes two built-in user accounts for maintenance and
management activities. Emerson recommends that administrators change the
default passwords listed below for security purposes.
Table 6 Built-in user accounts included on a new ATCA-S201
3.2.1
User account
Default
password
Description
admin
admin
root
root
The admin account was created for blade management activities.
This account should be used for all management and configuration
activities. Management logins may be performed via (1) Serial
console RS232, (2) ssh or (3) secure html on any Ethernet port.
The root account has master privileges with absolute power to
modify the blades Linux OS in any way desired.
It is unadvisable to use root as the normal user account because
simple typographical errors, accidental file deletions, or generating
unintentionally restrictive file permissions could render the blade
in-operable, requiring the factory reset procedure. For normal
activities, Emerson encourages using the admin user account and
judicious use of the su command only when root privileges are
really needed.
Password change procedure
The login password may be changed using the linux passwd command. For
example, if logged in as root, the password change procedure is shown:
#passwd
Changing password for root
Enter the new password (minimum of 5, maximum of 8 characters)
Please use a combination of upper and lower case letters and numbers.
Enter new password: xxxxxxx
Re-enter new password: xxxxxxx
Password changed.
#
3.2.2
Password recovery procedure
In the event that the administrator login “root” is lost or forgotten, it is possible to
clear it using jumpers provided on the ATCA-S201. The jumper location along with
6806800H62B ATCA‐S201 Installation and Use Guide 23 RTM-ATCA-SXXX Overview the clear password procedure is explained in section 9.4.3 of this manual. When
invoked, the user is prompted to set a new one at first login.
Note: The recovery procedure affects the “root” user only; No other user account
passwords are cleared.
3.3
Factory reset
Users can reset the blade to restore factory default settings. This procedure will
erase all existing blade configurations (network settings, volumes, shares etc). The
procedure is sometimes recommended following a major firmware upgrade.
i. Login into shell window as root
ii. At console prompt, type: fw_setenv setfactorydefaults 1
3.4
Configuring a new ATCA-S201 blade
Initial configuration and setup of your blade may be conducted over Ethernet or
serial (RS232) connections. Select the connection type that supports your preferred
management style, either CLI (command line tool) or HTML as outlined below:
Connection type
Command line tool
Serial/RS232 port on RTM
 Yes
Ethernet port on RTM
 Yes
 Yes
Base or fabric ports on ATCA
Zone-2 connector
3.4.1
Secure html tool
 Yes
 Yes
Serial ports
An RJ45 serial port can be found on RTM panel. The default baud rate and
communication settings are listed in Table 5 Console port, default terminal settings
in section 3.1.2. The serial port attributes such as baud rate may be changed in the
U-boot environment using the bootargs variable (see section 3.6.3 titled U-boot
environment variables).
3.4.2
Ethernet ports
An RJ45 Ethernet port can be found on RTM panel. It auto negotiates Ethernet link
speed s up to 1Gbps. Additional Ethernet ports (base and fabric) are provided on the
ATCA zone-2 connector. By default, all Ethernet ports will attempt to obtain an IP
address assignment form the DHCP (Dynamic Host Configuration Protocol) server
on the network. Administrators must log into your DHCP server to determine the IP
assignment. With the IP address, an administrator may connect to the ATCA-S201
using a secure shell (SSH) or an HTML browser which supports secure http
connections. The Ethernet equipment can be identified by finding the IP address(es)
corresponding to the following MAC address assignments:
MAC address OUI
00-11-0D-xx-xx-xx (hex)
6806800H62B ATCA‐S201 Installation and Use Guide 24 RTM-ATCA-SXXX Overview Note: If no DHCP server is present, the ATCA-S201 will deactivate this port. The
serial console must be then used to manually assign an IP address. This manual
initialization procedure is described in section 3.6 of this manual.
3.4.3
Management Configuration via HTML browser
Once the IP address of the Ethernet port is known, an administrator may use a web
browser to connect to the ATCA-S201 to perform and monitoring or configuration
tasks. For security, the browser must support secure https connections on TCP port
443.
Example: Type this address into the address field of your web browser:
https://192.168.1.xxx
Refer to chapter 4 , which begins the explanation and use of the html configuration
tool.
3.4.4
Management configuration via secure shell (SSH)
Once the IP address of the Ethernet port is known, an administrator may use a SSH
service to connect to the ATCA-S201 and to facilitate command line management.
For example:
ssh 192.168.1.211 –l admin
3.4.5
Management configuration via serial console shell
If the boot is not interrupted and has completed, the RS232 port accepts
administrator login for Linux shell access, and access to command line configuration
tools.

U-boot console tool
The ATCA-S201 employs a staged boot process that begins with U-boot. U-boot is
an open source boot loader program that is the first code executed at system reset.
As the boot execution commences, its progress may be monitored via the RS232
console port of the Advanced RTM. U-boot supplies several initialization
parameters to the Linux kernel that administrators may elect to modify. U-boot
employs a countdown timer with a default setting of bootdelay seconds, see table
below. If a key is pressed before this time, the auto boot procedure halts and the
administrator will see a U-Boot command prompt:
...
Hit any key to stop autoboot:

When is U-boot needed?
Users may never need the U-boot environment. U-boot is included to
accommodate atypical system maintenance situations such as:
 On site field servicing (must be connected via serial console)
 Network boot (rather than flash boot)
 Environments without a DHCP server
 Flash recovery

Ethact identifies which Ethernet resource is associated
with U-boot services. Permissible values:
eTSEC0= Zone2 connector, Base0 Ethernet (1Gbps)
eTSEC1= Zone2 connector, Base1 Ethernet (1Gbps)
eTSEC2= Zone3 connector, Management port (1Gbps)
Note: ethact may be dynamically changed at the U-boot
console, but it is not a persistent variable, and will be
reloaded at next boot.
RESERVED for future use
At boot, ethprime is copied to ethact. Refer to ethact for a
list of permissible values.
Manually assign management IP addresses
Administrators may individually modify any of the listed U-boot environment
variables. Note these changes are not permanently recorded in the non-volatile
flash unless saved using saveenv. Extreme care should be taken to ensure new
values are valid entries.
6806800H62B ATCA‐S201 Installation and Use Guide 32 RTM-ATCA-SXXX Overview To manually establish IP port address, a typical new system configuration might
consist of the following commands:
uboot=>
uboot=>
uboot=>
uboot=>
setenv
setenv
setenv
setenv
ipaddr 192.168.1.211
gatewayip 192.168.10.1
netmask 255.255.255.0
ethprime eTSEC2
Once all of the environment variables have been modified they persist only if
permanently recorded in the flash device. This is accomplished with this command:
uboot=>
saveenv
This example setup establishes initializes the 1Gb Ethernet port located on the RTM
for administrator login and management access.
3.7
Network boot procedure
The ATCA-S201 supports network boot which allows the user to bypass code
contained on the embedded flash devices, and instead load code images contained
on the network. Network boot does not replace stored user configurations.
Network boot requires that the network node supports tftp and must contain the
following source files located in directory named /tftpboot/:
Flash contents
U-boot code
Linux kernel code
File system code
Source file name
U-boot.bin
uImage
Rootfs.ext.gz.uboot
User configuration settings
...
Hit any key to stop autoboot:
uboot=> run ramboot

Note1: Network boot defaults to the Ethernet resource on the RTM. Alternatively,
the user may designate the zone-2 Base ports. Use setenv to change the ethprime
variable to accomplish this.
Note2: Use setenv to change the serverip variable to the tftp server IP address.

Administrators may individually enable and configure these ports. Configuration can be
done using the serial console port, Telnet or via HTML. This chapter assumes the reader is
familiar with internet protocols and TCP/IP networking.
Note: This chapter provides how-to-use details for the secure web configuration
tool. Optionally, the user may perform configuration by establishing a login session
from a secure shell (ssh) window, and running the command line utility (CLI). Refer
to section 3.4.5, titled Command line configuration tool for more information.

The user may perform HTML configuration with any browser that supports https .
Direct your browser to the any active IP port on the ATCA-S201. The ATCA-S201
employs https (encrypted secure sockets layer- SSL) technology to protect
configuration activity that occurs over IP links. The ATCA-S201 issues a self-signed
certificate, identified as “EMERSON”. This certificate is not registered with a
certificate authority, and the browser will pop up a warning as shown below. Users
must accept the certificate to proceed.

The system will automatically terminate (logout) a remote user after 10 minutes of
in-activity. Optionally, the user can create this file to set an alternate inactivity
threshold value (expressed in seconds):
# echo 60 >/etc/max_inactivity
Note: In absence of this file, the value is set to 600 seconds.

Forced user logout
A local user may immediately terminate an active management session by deleting
the following file:
# rm /tmp/curruser
The above command will require the remote user to re-login, or allow the
administrator to launch the atca_blade CLI tool locally.
4.3.2
Single session management override
Blade management is restricted to one admin user at a time, thus preventing blade
configuration conflicts from multiple remote locations. Moreover, a user may not
simultaneously operate the atca_blade CLI tool with the web GUI configuration tool.
Users may optionally override this protection mechanism using either of the
following mechanisms:
 Web GUI command

MTU defines the maximum size of a packet that the blade may transmit over the
network interface without fragmentation. A large MTU permits the system to send
fewer packets of a larger size to achieve the same network throughput, with
generally less OS and software overhead.
If you are not sure, you can often find the MTU size using a trial-and-error ping
command. First set the MTU to the max, then open a console port, and ping the
destination port, incrementing the size until no response is received:

DESCRIPTION
vconfig is a program which enables the user to create and remove vlan devices.
OPTIONS
add [interface-name] [vlan-id]
Creates a vlan-device on [interface-name]. The resulting vlan-device will be
called
according to the naming convention set. Users should avoid
using [vlan-id]= 1. Many hardware products use [vlan-id] 1 as the
management vlan. See linux manpage ‘vconfig’ for more information.
rem [vlan-device]
Removes the named vlan-device.
 Example #1: add a vlan interface to XAUI port 4, ID 66
# vconfig add eth4 66
# ifconfig eth4.66 up

Link aggregation and bonding
The ATCA-S201 supports 802.3ad link aggregation also known as “bonding”.
Bonding allows you to aggregate multiple Ethernet ports into a single group,
effectively combining the bandwidth into a single connection. For example, you can
aggregate the ATCA base channel ports (1 Gb/s each) into a trunk group, providing
2Gb/s cumulative bandwidth, fault tolerance and load balancing.
Base channel bonding example

Switch 1

The Linux bonding driver provides the ability to group ports,
detect link failures and reroute traffic to the surviving ports in
a manner transparent to the storage participants.

6806800H62B ATCA‐S201 Installation and Use Guide 47 RTM-ATCA-SXXX Overview 4.8.1
Bonding, CLI command syntax
The Linux community has created an extensive man page for ifenslave. The subset
of essential elements is summarized below.
Create new bond
Step1:
ifconfig eth0 down; ifconfig eth1 down
Step2:
Deactivate the Ethernet “slave” ports that will become bond members
modprobe bonding mode=0 miimon=100
This loads the bonding module, sets the usage policy mode and sets polling
frequency to 100mS. Several mode exist, but these are the most common
Valid mode=[ ] options:.
mode=0 - Round robin packet, or balanced transmit policy. This mode will
only work with switches that support trunking.
mode=1- Active-backup; one slave port is active, the other is passive. This
mode should work with any Layer-II switch.
Step3:
ifconfig bond0 <ip-address> up
Define a new bond0, and assign a dotted decimal <ip-address >. Note: the
MAC address of the bond0 device will be taken from the first slave device.
Step4:
ifenslave bond0 eth0; ifenslave bond0 eth1
Assign the slave ports that will comprise the new bond.
Preserve new
bond attributes
/etc/rc.d/init.d/userstart
This file contains a template for adding commands that will be executed on
boot (or shutdown) as required by the user. This file is stored in system flash
memory and preserved over reboots. Edit this file and add the entire
sequence of bond commands.
Example:
ifconfig eth0 down; ifconfig eth1 down
modprobe bonding mode=0 miimon=100
ifconfig bond0 <ip-address> up
ifenslave bond0 eth0; ifenslave bond0 eth1 eth1
Remove bond
Step1:
ifenslave -d bond0 eth0; ifenslave -d bond0 eth1
Remove all Ethernet “slave” ports that are bond members
Step2:
ifconfig eth0 down; ifconfig eth1 down
Step3:
Set the former slave ports as down.
/etc/rc.d/init.d/userstart
Remove the relevant bond creation code, and reboot

This chapter explains how to prepare and configure RAID volumes that are ultimately mapped to
the various IP services advertised on the ATCA-S201 ATCA carrier board. These virtual RAID
volumes are created from in-chassis storage pools comprised of AMC modules with SAS or SATA
disks. Hardware RAID services are available for disk striping (RAID0) and extended volume
mirroring (RAID1, RAID1E). Software RAID services are available for parity based disk striping
algorithms including RAID4, RAID5 and RAID6. The Software RAID features of this product can
provide better capacity utilization efficiency, but can consume a greater percentage of CPU and
system memory bandwidth.
NOTE: If RAID is not needed, please proceed to the next chapter.

These menus are used to view and arrange the hardware disk pool. The hardware
disk pool is the raw (unformatted/unassigned) disk capacity or resources available to
a ATCA-S201. In SNIA terminology, these are primordial disks. This storage is block
I/O comprised of the following:
1.
AMC SAS/SATA hard drive(s)
2.
RTM SAS/SATA hard drive(s)
3.
Disks or volumes accessed via an AMC SAS controller
4.
Disks or volumes access via an AMC FC controller
The sum capacity of the hardware disk pool resources equals the total size of
storage available to the particular ATCA-S201.
5.1.1
JBOD mode
Just a bunch of disks (JBOD) is a term to describe disks which are not part of a RAID
or logical device definition. By default, a new ATCA-S201 will scan and display all
discovered disks 1:1 in the physical disk menu. These disks may be used as-is, or
grouped using the configuration tools to create RAID or combined logical volumes.
Note: If the installation will use JBOD, and not use RAID, the user may proceed to the
next chapter.
5.2
Hardware RAID configuration Menu usage
On a new system installation, this configuration menu enables the creation of RAID
disk(s) that will appear in the physical disk menu. Once created, RAID disks are
managed in the same manner as other physical disks, but boast benefits including
improved performance and redundancy.

Description
Two or more disks are
grouped to provide a
capacity aggregation
function. The advantage is
the multiplicative
performance and capacity
effect of up to 10 spindles
working in concert to store
or retrieve data for the host.
Exactly two disks are grouped
to provide a mirror function.
By definition, two drives our
bounded in a fashion such
that every write to one drive
is mirrored to the second. If a
failure occurs with either
drive, data is still accessible
via the surviving drive.
Three or more disks are grouped to
provide a mirror function using an
algorithm extension to permit use
with many drives. If a failure occurs
with any drive, data is still accessible
via the surviving drives.

How new RAID definitions alter device menu display
The number of devices appearing in the Physical Disks menu will change once the
user applies RAID services. The figure below illustrates this concept. In this
example, there are four AMC disk modules available to the ATCA-S201, but only
three disks appear in the physical disk menu.

Software RAID configuration
Administrators may use the ‘MD RAID’ menus to configure the Software AID
features of ATCA-S201. The implementation leverages the mdadm tool available
with the 2.6.23 Linux kernel, which also offers the ability to conduct all volume setup
and configuration via a shell commands. Upon creation, a new software raid-device
will appear as a new device in web or cli configuration menus. Users may utilize the
new raid-device to create logical volumes, and configure iSCSI and NAS file shares.
The ‘MD RAID’ configuration tool appears within the html tool’s main navigation
panel on the left side as shown in the figure below.
NOTE: Software RAID should be applied before defining volume groups using the
logical volume manager (LVM).
5.3.1
Software RAID web-configuration menu usage
On a new system installation, this configuration menu enables the creation of RAID
disk(s) that will appear in the physical disk menu. Once created, RAID disks are
managed in the same manner as other physical disks, but boast benefits including
improved performance and redundancy.

Benefits of a logical Volume Group (/dev/vga)
A volume group is a group of one or more physical disks. A volume group gives the
administrator several powerful tools to manage storage resources.
These features include:
 Define volume groups with multiple disks or partitions
 Dynamically increase a volume group by adding new physical disks
6.1.1
Benefits of a Logical device/disk (/dev/vga/lva0)
A volume group may be divided into multiple pieces. Each piece is known as logical
device but may also be called a logical disk or volume. A Logical Device offers
powerful features that include:
 Essentially unlimited logical devices defined on each volume group
 Dynamically increase the size of logical device

Interpreting physical disk status
Physical disks resources can be mapped to logical volume groups, which are split
into Logical device ‘slices’ which are then shared as iSCSI or NAS. The number of
Physical disks may not necessarily correlate 1:1 with the hardware disk pool (e.g.
number of AMC drive carriers), because physical disks may include volumes created
through RAID services that mask the individual hardware disk members. From the
ATCA-S201 perspective, physical disks are presented as Linux SCSI devices
(/dev/sd[a-z]).

Step 1. Click the ‘add an iSCSI Target’ button.
After confirming the popup, the iSCSI configuration tool page changes, and will
display a list of operating attributes for the new iSCSI target. The menu will also
include a new section to create an iSCSI LUN (see next section).
7.1.2
Add or create an iSCSI LUN
The final step in defining a usable iSCSI resource requires the creation of one or
more iSCSI LUNs. A LUN (Logical Unit Number) is an addressable entity on the iSCSI
target. A target may have several LUNs, and each LUN maps one-to-one with a
logical share device. When an external host subsequently connects to the iSCSI
target, it may write to a LUN, which again is mapped to the logical device. An
external host may partition and format each LUN individually and write independent
data.
 CLI command syntax

Convention:
This command invokes an interactive session to modify the iSCSI setting of the
blade. The command will spawn a series of Yes/No questions which guide the user

offsets (R2T buffer offset for writes, or the smallest SCSI Data-In buffer offset within a read data sequence).
“No” — Not supported.
#ErrorRecoveryLevel
0
Default 0, Establishes the recovery level supported by the target.
#HeaderDigest <CRC32C|None>
"None" — default. CRC not enabled.
"CRC32C" — Indicates Target will support CRC32C checksum to protect iSCSI PDU’s headers, if requested by
initiator.
Notes: (1) header digests are not used during discovery sessions. (2) CRC32C may negatively affect overall target
performance.
#DataDigest <CRC32C|None>
"None" — default. CRC not enabled.
"CRC32C" — Indicates Target will support CRC32C checksum to protect iSCSI PDU’s data segments, if requested

iSCSI Discovery filter configuration (expert mode)
The iSCSI service running on the storage blade includes the ability to limit the
targets each host will see during discovery; this can often significantly reduce the
iSCSI boot time. The filter mechanism uses the host IP address as criteria to expose
or hide iSCSI targets listed in discovery.
Note: This mechanism is not meant to replace the CHAP security features used to
authenticate a host and target.
The iSCSI discovery filter is configured via simple edits to a pair of text based
configuration files:
/etc/initiators.allow
/etc/initiators.deny
The file syntax is explained in the next section. File changes become active
immediately upon save, no reboot is necessary.
Notes: Comment lines must start with a ‘#’ as first character.
- The file consists of one or more iSCSI iqn Target names.
- If a target iSCSI iqn is not listed in these files, no filtering is applied (this is default
case)
- To establish a discovery filter, a target’s iSCSI iqn name must appear in both files.
 /etc/initiators.allow
Enter the iSCSI iqn followed by one or more ip addresses. Use a comma to separate
multiple IP address entries. (Note: Entries must not use tabs)
iqn.1995-07.com.emerson:BladeHost.Target0 192.168.1.109
iqn.1995-07.com.emerson:BladeHost.Target1 192.168.1.108, 192.168.1.110
 /etc/initiators.deny
For each iSCSI iqn listed above, make a corresponding entry as shown. Each entry
should consist of the iSCSI iqn, followed by the word ALL (Note: Entries must not use
tabs).

 Export option syntax:
<export><host1>(<options>) <hostN>(<options>)
Note: Refer to the exports man page for details on other lesser-used options.
Table 36 Common nfs export option definitions
host1-hostN
Host specifies the directory on the storage blade that is the target of the export.
Option <wdelay|no_wdelay>
no_wdelay- (default) option turns off the delayed writes feature; no_wdelay must be accompanied with the
sync option.
wdelay- option causes the NFS server to delay writing to the disk if it suspects another write request is imminent.
This can improve performance by reducing the number of times the disk must be accessed by separate write
commands, reducing write overhead.
Option <root_squash>
This default setting prevents root users connected remotely from having root privileges and assigns them the
user ID for the user nfsnobody. This effectively "squashes" the power of the remote root user to the lowest local
user, preventing unauthorized alteration of files on the ATCA storage blade.
Option <ro|rw>
ro - Mounts of the exported file system are read-only. Remote hosts are not able to make changes to the data
shared on the file system.
rw- (default) Mounts of the exported file system are read/write. Remote hosts are able to make changes to data
shared on the file system
Option <sync>
The sync setting (default) instructs the Linux kernel to minimize the amount of write data kept in volatile system
memory. Though it is sometimes slower to complete all writes to disk, doing so can prevent data loss in the
event of a power failure.

Blade Maintenance and
Firmware upgrades
This chapter provides information about preserving all existing blade configuration settings
and also installing and updating the firmware loaded on the ATCA-S201 storage services
blade. At manufacturing time, the ATCA carrier is pre-loaded with firmware prior to
shipping. Periodically, new firmware releases are offered to improve the functionality or
performance of the ATCA carrier blade.
9.1
Blade Maintenance
The following section describes how to create a backup of an existing blade
configuration and how to restore this configuration on a replacement blade. The
procedure will record the iSCSI, NAS, volume, and share privileges of all disk storage
connected to the ATCA-S201. Moreover, it will record IP attributes of all fabric, base
and RTM Ethernet ports, as well as any VLAN, bonds or RAID definitions.
9.1.1
Backup your blade configuration
The ATCA-S201 blade software keeps all system configuration data in a single
archive file. This file contains all customizations made by the user over the life of
the blade. Administrators can manually copy this file to a safe location and later
reload the configuration if needed.
The following procedure is a detailed description of the web-based export system
configuration procedure.
 Export System configuration file using web-GUI tool
Step 2. Navigate to the Maintenance menu. Click the ‘Export’ button.
Step 3. Acknowledge the popup window to confirm and commence the export.
The action will create a backup file on the host which can be later imported.

ATCA Firmware
All firmware code is stored in a single EEPROM flash device located on the carrier
blade. The ATCA-S201 flash device is partitioned into regions containing the
following code functions:
 U-boot
 Linux Kernel (kernel)
 Root file system and storage applications (rfs)
 Non-Volatile blade configuration Data (NVDATA)
6806800H62B ATCA‐S201 Installation and Use Guide 96 RTM-ATCA-SXXX Overview Each image contains a CRC signature which is validated by the system prior to
loading. The normal methods for updating these code images is to establish a
management connection, ( see chapter 3 ) login as administrator, and utilize either
the command line interface (CLI) or web-based graphical user interface (GUI)
interface outlined later in this chapter . Both of these mechanisms require that the
existing firmware is known-good and intact.
Additionally, an alternate emergency recovery method is provided to repair flash
contents that are blank, erased or corrupted.

flash_update.sh tool usage and options
Emerson offers a shell script (.sh) to update firmware code stored in flash. This
command line script is named sbflash, and is located on the /bin directory of the
ATCA-S201.
SYNOPSIS
sbflash
[-r] [-k] [-u] [-t tftp_serverIP]
DESCRIPTION
sbflash is a shell script which enables the user to selectively update some or all of the
firmware components. A blade reboot is required to activate the new firmware
components.
6806800H62B ATCA‐S201 Installation and Use Guide 99 RTM-ATCA-SXXX Overview OPTIONS
-r: indicates the root file system should be replaced with the image on the tftp
server.
-k: indicates the linux kernel should be replaced with the image on the tftp server.
-u: indicates the uboot components should be replaced with the image on the tftp
server.
-t tftp_serverIP: used to specify the dotted decimal IP address of the remote tftp
server.
(example -t 192.168.1.151). If this option is omitted, the script will search for tftp at
the IP address assigned to U-boot variable assignment for serverip.

The following procedure is a detailed description of the CLI flash update procedure:
 Upgrade firmware procedure
1.
Establish console or ssh access to the ATCA-S201. Must be user root.
2.
Install a second host machine on the same IP network as the ATCA-S201. This
machines IP address must be visible from the ATCA-S201. Use ping to validate it
is accessible. (e.g. ping 192.168.xxx.xxx)
3.
Load the second host machine with TFTP server software. A good quality tftp
program is offered by PumpKIN, an open source and free implementation that
is written to RFC1350.
4.
Copy all new firmware file to the secondary host machine named /tftpboot/
5.
Execute the following command from the ATCA-S201 shell

Emergency firmware recovery, theory of operation
The ATCA-S201 hardware actually contains two copies of flash code. The primary
image used for normal customer carrier operation, while the second image contains
a backup copy preserved for emergency firmware recovery tasks. The contents of
the backup flash remain fixed at time of manufacturing and there is no end-user
mechanism to modify its contents. This ensures the device is not accidentally rewritten or erased. A jumper on the ATCA blade is used to instruct the CPU to boot
either the primary flash (normal) or the secondary flash (emergency recovery).
9.4.1
Jumper Settings
The ATCA-S201 carrier board includes jumpers that are used for special recovery and
reset procedures. Jumper locations are shown in Figure 30. Jumpers create an
electrical connection between two pins which can be sensed by circuitry on ATCAS201 to enter special service modes or behavior. Pin 1 is identified with a square
solder pad on the printed circuit board. Jumper behavior is described below.

Emergency flash recovery (factory reset)
The method described in this section explains a procedure to repair primary flash
contents that are blank, erased or corrupted. We advise against using this
emergency recovery procedure if the ATCA-S201 is functional, and management
communications can be conducted.
 Upgrade firmware procedure
1.
Remove the ATCA carrier the chassis (see 2.9, Removing the ATCA carrier
blade)
2.
Locate header JP1, and move the jumper to the service setting. This causes the
blade to fetch firmware from the read-only factory flash.
3.
Re-install the ATCA blade into the chassis and allow it to reboot.
6806800H62B ATCA‐S201 Installation and Use Guide 102 RTM-ATCA-SXXX Overview 4.
The ATCA blade will break into the U-boot console.
5.
Establish a serial connection, login into the blade as root (see section 3.2)
6.
Use printenv to list the environment variables. Assign a serverip address to
match the tftp server address in the next step , for example: setenv serverip
192.168.xxx.xxx
7.
Install a second host machine on the same IP network as the ATCA-S201. Its IP
address must match the serverip address listed in the previous step.
8.
Load the second host machine with TFTP server software. A good quality tftp
program is offered by PumpKIN, an open source and free implementation that
is written to RFC1350.
9.
If necessary create a directory on the secondary host machine named /tftpboot/
10. Place the new blade firmware image(s) for the primary flash device in
/tftpboot/
11. When all pieces are in place, go to U-boot console and type: run ramboot
12. Watch U-boot console, and wait for output message: “Primary flash successfully
restored”
13. Remove the ATCA carrier the chassis
14. Locate header JP1, and move the jumper to the normal setting.
15. Re-install the ATCA blade into the chassis and allow it to reboot normally.
9.4.3
Clear root password
For security purposes, administrators are encouraged to change factory default
passwords to protect unauthorized access and configuration of the storage blades
resources. The method described in this section explains a procedure to clear the
blades root password to factory default. None of the other user account passwords
are cleared.
 root password reset procedure (method 1)
This procedure is useful when the user has no access to the RTM serial console port.
1.
Remove the ATCA carrier the chassis (see 2.9, Removing the ATCA carrier
blade)
2.
Locate header JP2, and move the jumper to the service setting.
3.
Re-install the ATCA blade into the chassis and allow it to reboot.
4.
Inspect the LED’s on the front panel. When the ATCA Health status begins
blinking green, the password reset has occurred.
5.
Power down the blade and again remove it from the chassis.
6.
Locate header JP2, and move the jumper to the normal setting.
7.
Re-install the ATCA blade into the chassis and allow it to reboot.
6806800H62B ATCA‐S201 Installation and Use Guide 103 RTM-ATCA-SXXX Overview 8.
Administrators may login as root. There is no password, and the ‘root’ user will
be asked to create one.
 root password reset procedure (method 2)
This procedure is useful when the user has access to the serial console port and can
operate the U-boot environment. This secondary method allows you to clear the
root password without removing the blade from the chassis but does require a
power cycle and some familiarity with U-boot.
1.
Establish a connection to the serial port (RS232)
2. Reboot the blade:
# reboot
3.
Stop the normal boot sequence; enter the U-boot menu.
(see section 3.6.1)
4.
Type the following series of U-boot commands:
uboot=> setenv resetroot 1
uboot=> run flashboot
The above commands will continue the boot sequence and trigger the blades Linux
file system to clear the root password. No other passwords are cleared. Do not use
saveenv after setting resetroot, otherwise the root password will be reset on every
re-boot.

PCI-Express transmit differential pair signals
PCI-Express receive differential pair signals
Fabric clock, as defined in AMC.0 specification. Intended to be used for PCI-Express 100MHz
spread spectrum clock. This signal can be either terminated or passed through the CREFCLK
via jumpers on the RTM403. The ATCA blade provides no spread spectrum support.
PCI-Express reset signal (input). The ATCA board may drive a Logic low to reset PCI-Express
switch and PCI-Express interfaces that are behind it.
RTM# signal is grounded by the ATCA-S201 to indicate a MMC controller is present (see AMC.0
specification.) The ATCA implementation shall include a 10Kohm pull-up resistor to
management power on the ATCA. In this way, an ATCA is able to detect non-intelligent vs.
intelligent RTMs.
PCI-Express bus configuration signal. It shall be grounded on RTMs that use a single x8 PCIExpress bus and pulled up on the ATCA with 10Kohm resistor to management power. On RTMs
that expect two x4 PCI-Express busses this pin will float (not be connected). Two x4 PCI Express
busses are intended for RTM implementations that desire to avoid PCI-Express switch in order
to reduce latency. The ATCA-S201 asserts logic ground to this signal.
Active low RTM present signal.PS0# is tied to logic GND on the ATCA blade. PS0# (Connector
J33) and PS1# (Connector J30) shall be connected through a diode on the ATCA-S201, exactly
as defined in AMC.0 specification. PS1# is last mate on Power connector and PS0# is on the
opposite end of the set of connectors. Logic low on PS1# indicates that RTM is present and
fully inserted.
When low indicates to RTM that it is fully inserted and that MMC can start execution. Logic
high shall keep MMC in reset state. This signal shall have a pull-up resistor as indicated in
AMC.0 specification.
These pins provide a functional JTAG port on the P33 connector. The JTAG chain is for mfg
testing only and the chain is not intended for RTM use.
This bus allows an RTM to place peripherals on the ATCA serial management bus.

12.1 Installation and Removal of the Rear Transition Module
The RTM-ATCA-SXXX can be installed into an ATCA shelf (chassis) with a midplane
made for front and rear board installations. The module must be installed in the slot
directly behind the host ATCA node board. These back-to-back slots have common
pins to enable passing of signals via the Zone-3 connector complex.
12.2 Important Information about Your Chassis
Before installing the rear transition module, verify the module’s part number to
ensure that the correct rear transition module is being installed into the system. For
information on identifying the rear transition module, see Section11.6.
12.2.1 Safety Statement
The RTM-ATCA-SXXX is designed to comply with UL60950-1, and is intended to be
used with similarly tested ATCA products that have a user’s guide detailing user
installation of module accessories.
12.2.2 Observe Maximum Module Current Requirements
There are several manufacturing options for the RTM. The diskless version of the
RTM requires no power from the front ATCA node board, but may draw up to
200mA from the 3.3 V management power source. Be sure to validate that the host
chassis can supply the RTM slot with these maximum current requirements.

12.3 Before You Install Or Remove The RTM
Boards may be damaged if improperly installed or handled. Please read and follow
the guidelines in this section to protect your equipment.
12.3.1 Observe ESD Precautions
Emerson strongly recommends that you use an antistatic wrist strap and a
conductive foam pad when installing or upgrading a system. Electronic
components, such as disk drives, computer boards, and memory modules, can be
extremely sensitive to electrostatic discharge (ESD). After removing the component
from its protective wrapper or from the system, place the component flat on a
grounded, static-free surface (and, in the case of a board, component side up). Do
not slide the component over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by
wearing an antistatic wrist strap (available at electronics stores) that is attached to
an active electrical ground. Note that a system chassis may not be grounded if it is
unplugged.
12.3.2 Watch for Bent Pins or Other Damage
Bent pins or loose components can cause damage to the board, the backplane, or
other system components. Carefully inspect your board and the backplane for both
pin and component integrity before installation. Our suppliers take significant steps
to ensure there are no bent pins on the backplane or connector damage to the
boards prior to leaving our factory. Bent pins caused by improper installation or by
boards with damaged connectors could void the warranty for the backplane or
boards.
If a system contains one or more crushed pins, power off the system and contact
your local sales representative to schedule delivery of a replacement chassis
assembly.
6806800H62B ATCA-S201ATCA-S201 Installation and Use Guide
125
RTM‐ATCA‐SXXX Installation 12.4 Use Caution When Installing or Removing RTM
When first installing boards in an empty chassis or onto a carrier card, we
recommend that you start at the left of the card cage and work to the right.
When inserting or removing a board in a slot adjacent to other boards, use extra
caution to avoid damage to the pins and components located on the primary or
secondary sides of the boards.
12.4.1 Preserve EMI Compliance
To preserve compliance with applicable standards and regulations for
electromagnetic interference (EMI), during operation all front and rear openings on
the chassis or board faceplates must be filled with an appropriate card or covered
with a filler panel. If the EMI barrier is open, devices may cause or be susceptible to
excessive interference.
12.4.2 Understand Hot Swap
Your RTM is electrically designed for hot swap within a fully powered chassis. To
facilitate hot swap, there is a blue LED on the rear faceplate. This LED is under
software control.
If your system is using software that provides full hot swap capabilities, the software
will illuminate the blue hot swap LED on the rear faceplate when software has
stopped and it is safe to remove the advanced rear transition module.
If your system does not have hot swap-aware software running, behavior of the blue
LED is indeterminate. In this case, you may need to manually shut down applications
or operating systems running on the board prior to board removal, even if the blue
LED is lit.
Powering down or removing a board before the operating system or other software
running on the board has been properly shut down may cause corruption of data or
file systems.
12.5 Verify Slot Usage
Prevent possible damage to module components by verifying the proper slot usage
for your configuration.
12.6 Installing the Advanced Rear Transition Module
This section describes a recommended procedure for installing the RTM module in a
chassis.
Before you install your module, please read all cautions, warnings, and instructions
presented in this section.
6806800H62B ATCA‐S201 Installation and Use Guide 126 RTM‐ATCA‐SXXX Installation Handling modules and peripherals can result in static damage. Use a grounded wrist
strap, static-dissipating work surface, and antistatic containers when handling and
storing components.
Insert the board by holding the Module Handles–do not exert unnecessary pressure
on the faceplate.
Hot swap compliant modules may be installed while the system is powered on. If a
module is not hot swap compliant, you should remove power to the slot or system
before installing the module.
5.
Verify that you have taken the necessary antistatic precautions.
6.
Go to the back of the system and choose an appropriate slot for the rear
transition module.
Rear transition modules must be installed in-line behind the accompanying
node board. For example, if the accompanying node board is going to be
installed in slot 3, its rear transition module must be installed at the back of the
system in slot 3.
7.
Remove the slot filler panel from the selected node board slot, if necessary.
8.
Prepare the module by loosening the locking screws and opening the
injector/ejector latch at the top of the module as shown in the figure below.
Figure 41 Injector / Ejector Latch and Locking Screw
9.
Carefully align the edges of the module with the guides in the appropriate slot.
It might be helpful to look into the enclosure to verify correct alignment of the
rails in the guides. Align the edges of the module with the card cage rail guides
in the appropriate slot.
10. Taking care to keep the module aligned in the guides, apply equal and steady
pressure and slide the module in until the injector/ejector mechanism engages
the retention bars.
6806800H62B ATCA‐S201 Installation and Use Guide 127 RTM‐ATCA‐SXXX Installation 11. Position your thumbs at the top and bottom of the RTM; simultaneously push in
the module and rotate the injector/ejector mechanisms inward to their closed
position to seat and secure RTM. DO NOT FORCE THE BOARD INTO THE SLOT.
12. Tighten the two module retention screws to secure the module into the shelf.
13. Power on the system, if necessary. Refer to your system manual for instructions
on correctly powering on the system. Once power is applied to the chassis, the
internal MMC controller runs a self-test that runs for approximately 10 seconds.
Upon a successful power up self-test, the blue hot swap LED will blink and then
turn off, indicating that the module has been placed in operation.
12.7 Removing the Advanced Rear Transition Module
The RTM-ATCA-SXXX is hot-swappable and can be removed from the chassis
without powering down its associated node board. This section describes a
recommended procedure for removing a board module from a chassis.
Before you remove your module, please read all cautions, warnings, and instructions
presented in this section. Hot swap compliant modules may be removed while the
system is powered on. If the chassis is not hot swap compliant, you should remove
power to the slot or system before removing the module.
To remove a rear transition module, follow these steps:
14. Loosen the locking screws on the rear transition module.
15. Rotate the top ejector handle to the half way (HW) position. Do not remove the
module immediately.
16. If your host module running hot swap-aware software, the action of rotating
the ejector lever will start the shutdown process on the board. The software will
slowly blink the blue hot swap LED indicating the module is in the process of
being de-activated.
17. Once the module has been de-activated, the Blue LED will illuminate steady.
Once this is done you can extract the module by pulling on the module handle.
Note: Powering down or removing a board before the operating system or
other software running on the board has been properly shut down may cause
corruption of data or file systems.
18. If your board or system is not running hot swap-aware software, the blue LED
may illuminate without regard to software processes still running on the board.
Be sure to manually shut down applications or operating systems running on
the board prior to board removal.
19. Carefully pull the module from the chassis.
20. If the card slot is to remain empty, install a filler panel in the slot.
12.8 Verifying the Hardware Installation
This section provides information to verify the installation of the RTM-ATCA-SXXX.

6806800H62B ATCA‐S201 Installation and Use Guide 14‐4 15 IPMC Firmware Upgrade
Procedure
This chapter provides the instruction for upgrading the IPMC (Intelligent Platform
Management controller) firmware. If the ATCA-S201 requires new firmware, an upgrade can
be performed remotely using a LAN connection to the self manager.
15.1 The ipmitool utility
Firmware upgrades are accomplished with ipmitool, a utility for managing IPMIenabled devices. The utility is an open source derivative which is modified by the
shelf management supplier.
The ATCA-S201 keeps a redundant copy of the firmware in the FLASH. Upgrades are
reliable and reversible. A failure in the download (error or interruption) does not
disturb the IPMC's ability to continue using the "old" firmware or its ability to restart
the download process. The IPMC automatically fails back to the previous firmware if
there is a problem when first running new code.
SYNOPSIS
The minimum information to complete a firmware upgrade is documented here.
$ ipmitool [-I|-H|-T|-B|-t|-b] hpm upgrade <firmware_file>
$ ipmitool [-I|-H|-T|-B|-t|-b] hpm activate
DESCRIPTION
ipmitool lets you manage Intelligent Platform Management Interface (IPMI)
functions of either a local or remote system using IPMI V1.5 and IPMI v2.0.
Capabilities include printing FRU data, LAN configuration, sensor readings, and
remote power control.
OPTIONS
Table 77 ipmitool options relevant to firmware upgrades

Description
-I <interface>
Selects IPMI interface to use. Supported interfaces that are compiled in
are visible in the usage help output. Use lan to designate Ethernet.
Remote server address, can be IP address or hostname. This option is
required for lan interfaces.
If updating AMC, use this to specify optional bus address of the bridge
device (ex: Carrier IPMB-0 address if updating an AMC)
If updating an AMC, these this optional bus ID of the Bridge device (ex: 0
if updating through a IPMC
IPMB-L address of the final target
-H <address>
-T <address>
-B <bus id>
-t <address>
-b <bus id>
bus ID of the final target [0=IPMB-0(IPMC), 7=IPMB-L(AMC)]

IPMC Firmware Upgrade Procedure COMMAND SYNTAX EXAMPLES
EXAMPLE 1. The following example shows the command sequence for firmware
upgrade of an AMC installed on a carrier:
$ ipmitool -I lan -H 192.168.0.2 -T 0x82 -B 0 -t 0x74 -b 7 hpm upgrade
hpm1fw.img
$ ipmitool -I lan -H 192.168.0.2 -T 0x82 -B 0 -t 0x74 -b 7 hpm activate
Line 1 puts the new firmware in the flash device, where hpm1fw.img is the image.
Line 2 is used to dynamically load and activate the new firmware.
EXAMPLE 2. The following example shows the command performing firmware
upgrade on the carrier itself:
$ ipmitool -I lan -H 192.168.0.2 -t 0x82 -b 0 hpm upgrade hpm1fw.img
$ ipmitool -I lan -H 192.168.0.2 -t 0x82 -b 0 hpm activate
Line 1 puts the new firmware in the flash device, where hpm1fw.img is the image.
Line 2 is used to dynamically load and activate the new firmware.
