1 iPBridge 2500 provide storage options
Two protocols available on the iPBridge 2500 allow storage devices such as hard drives, tape drives
and libraries and CD jukeboxes to attach easily to Internet Protocol networks such as Gigabit Ethernet.
The ATTO iPBridge supports the high throughput needs of streaming data transfers, optimizing
performance and management using ATTO Technology intelligent Bridging ArchitectureTM.
The ATTO iPBridge 2500 has two models
depending on the protocol you have chosen: either
the iSCSI protocol or the NDMP protocol.
The iSCSI protocol increases the capabilities and
performance of storage data transmission by
transmitting data over local area networks
(LANs), wide area networks (WANs), or the
Internet, providing location-independent data
storage and retrieval to enhance current and future
Storage Area Networks (SANs).
NDMP version 4.0 provides backup for networkattached storage (NAS) tape and CD devices.
NAS devices are dedicated file servers and cannot
host applications such as backup software. NDMP
defines a common agent to interface between any
NAS device and any backup software program,
minimizing demand on network resources, and
enabling local backups and disaster recovery. The
protocol is being developed by the Storage
Networking Industry Association (SNIA) NDMP
Working Group.
Gigabit Ethernet (GbE) is a transmission
technology based on the Ethernet format and
protocol used in local area networks (LANs). It
provides a data rate of 1 billion bits per second
(one gigabit) as defined in the IEEE 802.3
standard.
intelligent Bridging Architecture, the engine
within ATTO FibreBridgeTM and iPBridge
products, uses ATTO Data Routing Fabric
topology and ATTO Virtual Device Manager to
optimize performance.
The iPBridge 2500C/R/D provides a compact
embeddable, rack or desktop solution which may
be installed in a wide range of system
configurations. Uniquely designed to support the
high throughput needs for applications that
require streaming data transfers (data backup), the
iPBridge optimizes performance by using ATTO
Technology intelligent Bridging Architecture.
You may choose an iPBridge 2500C/R/D which
supports the iSCSI protocol or one which supports
the NDMP protocol, maximizing application,
system and network configuration flexibility and
support.

2 Configuring the iPBridge
Set up your iPBridge by first getting an IP address, then use ATTO ExpressNAV to map devices. Default
values are appropriate for most configurations, but may be modified for your needs using ATTO
ExpressNAV.
Configuration of the ATTO iPBridge, also known
as iPBridge Services, is available through the
ATTO ExpressNAV, a browser-based interface, or
the Command Line Interface (CLI).
ATTO iPBridge Services configures and tunes the
iPBridge for many different environments and
applications, updates the firmware, configures the
addresses of the connected devices, monitors
status and reports on hardware.
To use the iPBridge, you must
1
Know the IP address for the iPBridge. (Refer to
Getting an IP address on page 10).
2
Map devices so that the iPBridge can access
the devices in your network. (Refer to Mapping
devices: NDMP on page 13 and Mapping
devices: iSCSI on page 15).
Additionally, it is best practice to change the
default user name and password and to set the
Real Time Clock. Refer to Additional
configurations on page 19

Configuration: Ethernet
2.2 NDMP configuration provides backup
NDMP (Network Data Management Protocol) provides backup for network-attached storage (NAS)
devices. NAS devices are dedicated file servers and cannot host applications such as backup software.
NDMP defines a common agent to interface between any NAS device and any backup software program,
minimizing demand on network resources, and enabling local backups and disaster recovery.
Note
For NDMP-configured iPBridge 2500 models
only
The ATTO iPBridge 2500, using the NDMP
Version 4 Protocol Specification, 10/2001, (skardal-ndmp4.03.doc), allows you to back up
critical data locally using any combination of
network-attached servers, backup devices and
management applications from a central control,
without taxing network traffic, by separating the
data path and the control path.
How NDMP works
The NDMP protocol allows data backup and
restoration over telnet networks using file-level
commands, rather than block-level IO
instructions.
The typical NDMP setup includes
•
•
•
a Data Service (usually disks)
a Tape Service
a client in control of the backup process called a
Data Management Application (DMA).
The DMA controls the NDMP session. There is a
master-slave relationship between the DMA and
the data/tape servers. The iPBridge 2500
implements the Tape Service, along with a SCSI
Service, to provide access to media changer
devices.
The iPBridge 2500 platform provides several
different types of management capability,
including telnet/FTP through the two GigE data
ports and an Ethernet 10/100/1000 management
port which may be used as a data port in the
iPBridge 2500 iSCSI-configured model, serial
CLI management, and standard bridge hardware
health checking.
A typical NDMP application involves a drive
array, a host computer and a tape library. the host
11
ATTO Technology Inc. iPBridge Installation and Operation Manual
computer may be attached to the disk and tape
drives by any of several methods/technologies.
The iPBridge uses Ethernet and Internet
protocols.
The following example describes a host, Ethernet,
tape library configuration.
1
The DMA sends messages to the tape library’s
SCSI Server to pick the appropriate cartridge
and load it in the tape drive.
2
The DMA sends commands to the tape drive to
position the tape and configure the tape for
writing (block size, etc.).
3
The DMA opens a connection to the Data
Server to exchange backup information.
4
The DMA commands the Tape Server to
prepare to receive data.
5
The Tape Server responds with addressing
information.
6
The DMA passes the address to the Data
server.
7
The Data Server and Tape Server send data
directly to each other.
8
Metadata generated by the DMA is written to
tape to indicate the end of files, directories, path
names, etc., passed through to the tape server
between backup data transfers.
•
NDMP uses a windowing mechanism in
which the Tape Server writes a portion of the
data, then pauses and waits for the DMA to
take charge. The DMA may start a new
window or write some Metadata.
•
The DMA may also move the tape while the
transfer is paused. Once the DMA has
finished with the Metadata, a new window is
established and the transfer from the Data
Server to the Tape Server continues.
•
The Data Server has no notification of the
Tape Server being paused, so it must rely on
the TCP stack to queue up data transferred
during the pause time, and to implement flow
control when queues are full.
Setting up NDMP
The ATTO iPBridge should first be configured for
the network using the RS-232 port to establish the
correct IP address, subnet mask, gateway and
iPBridge names. Authentication can require the
use of a client name-password pair, along with
configuration of the security level (MD5, Text, or
None) used for authentication. The iPBridge 2500
does not validate the client-name, and a single
password is used for all password fields within the
iPBridge 2500.
The NDMP port number is user-configurable,
with the industry standard (10000) as the default.
NDMP device mapping links a SCSI btl (bus,
target, LUN) to an ASCII device name. If you do
not use the default mapping, you must map
devices before using NDMP.

2.4 Mapping devices: iSCSI
SCSI devices are mapped using the designations for the SCSI bus, target and LUN. CLI commands are
used to modify the mapping. The easiest way to map devices is to use the Automap command, either
through the CLI or the browser-based interface, ATTO ExpressNAV.
Note
For iSCSI-configured iPBridge models only.
To map devices, you must have a host
computer connected to the iPBridge serial port
or an Ethernet port. Refer to Getting an IP
address on page 10.
The recommended management tool for the
iPBridge is ATTO ExpressNAV.
By default, a host or initiator views the iPBridge
as a single iSCSI node with all available SCSI
devices shown as LUNs on a single iSCSI target.
Refer to Exhibit 2.4-1
You may use Multiple Target mode to break the
single iSCSI node into multiple nodes. Multiple
Target mode allows you to grant or deny access
between initiators and devices as needed. Refer to
Exhibit 2.4-1
Node names
iSCSI nodes are accessed through the Ethernet
ports on an iPBridge, each identified by its own IP
address.
The iPBridge uses the iqn name format,
referencing the device serial number, to guarantee
that the target name is world-wide unique:
iqn.1995-12.com.attotech:ipbridge:
serialnumber
CAUTION
Changing the device map can affect the
host’s view of devices and your application
configuration.
Single Target mode
Single Target mode is the default. Use ATTO
ExpressNAV interface to map devices
automatically or manually. Refer to ATTO
ExpressNAV interface on page 21.
Map devices automatically
1
From the ExpressNAV main
menu, click on the Mapping
menu item on the left side of the
screen.
2
Click AutoMap
3
Click Submit
Map devices manually
1
From the ExpressNAV main
menu, click on the Mapping
menu item on the left side of the
screen.
2
Select the devices from the box
on the right hand side of the
15
ATTO Technology Inc. iPBridge Installation and Operation Manual
screen and drag to the appropriate LUN on the
left.
3
Click Submit.
Multiple Target mode
Multiple Target mode breaks the single iSCSI
node of the iPBridge and replaces it with a much
more configurable mapping scheme. This new
mapping scheme allows you to segregate storage
into different iSCSI nodes within the iPBridge,
with each iSCSI target having its own set of
access criteria.
For example, if you have two servers and a library
with four tapes and a media changer, the default
mapping would provide both servers access to all
tapes and the media changer (single target mode).
If you configured Multiple Target mode, you
would be able to map some devices to one server
and other devices to the other server, requiring
separate usernames and passwords for access.
CAUTION
If actual storage is mapped to more than
one iSCSI target and a server has
authorization for both targets, the server
could show duplicate storage without any
warning to the user.
If Multiple Target mode is enabled, the
Automap, Route, RouteDisplay and CHAP
CLI commands behave differently. (Refer to
iSCSI commands on page 55)
To control access, different CHAP account names
and CHAP secrets can be assigned to each target.
(Refer to iSCSI commands on page 55)
Single Target mode is the default. Use ATTO
ExpressNAV interface to map devices
automatically or manually. Refer to ATTO
ExpressNAV interface on page 21.

6 Troubleshooting
If it is clear that a particular component system is at fault in a problem situation, go directly to that
component. If it is not clear, the best approach is to troubleshoot using the inside-out method.
You may check on the status of your iPBridge using
the ExpressNAV interface. Refer to ExpressNAV
pages on page 23 to see which pages may contain the
information you need. You may also look for
information by using the diagnostic CLI commands,
enumerated in Diagnostic commands on page 43, in
the Advanced page of the ExpressNAV interface, or by
using the CLI directly (refer to CLI provides ASCIIbased interface on page 35.)
To start and use the ExpressNAV interface, including
how to access the version information, refer to ATTO
ExpressNAV interface on page 21.
Inside out method
To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first, then work
your way out.
•
SCSI devices
• iPBridge SCSI ports
• iPBridge internal configuration
• iPBridge Ethernet/IP ports
• LAN/WAN
• Ethernet host adapter or NIC in host
• iSCSI OS driver
• OS
• Application
Check the host event log
Check the event log on the host. Look for the most
recent entries and determine what could be causing a
problem, then go to that event and continue
troubleshooting.
Check the iPBridge event and trace logs
Check the iPBridge event log through the CLI. Refer
to Diagnostic commands on page 43. Look for the
most recent entries and determine what could be
causing a problem. Then go to that event and continue
troubleshooting.
Visually inspect LEDs
Light Emitting Diodes (LEDs) are located on both
sides of the iPBridge
If there is a non-fatal power supply problem, or if a
problem is detected before shut down occurs, the
Fault LED flashes. The Fault LED also flashes briefly

ATTO Technology Inc. iPBridge Installation and Operation Manual
Each SCSI bus has its own LED to show activity on
that bus. The LED blinks when I/O is occurring and is
solid when there is heavy activity.
The Fault LED lights yellow when the iPBridge is
turned on, then immediately goes dark. Software
activates the LED if there is a system error.

Component check
Use this procedure to check system components. For
more information on the commands used in this
procedure, refer to CLI provides ASCII-based
interface on page 35.
Checking SCSI devices
1
Check SCSI devices to make sure they are all
set to different SCSI IDs.
By default, the iPBridge SCSI ports use SCSI
ID 7 so drives should use IDs 0 through 6 and 8
through 15.
2
Check the SCSI device power. Make sure the
devices are powering up.
3
Watch the drive lights before, during, and after
startup. Many drives have term power lights
that should be on before startup and turn off
when system boots.
4
Verify the external terminator is the correct type
and does not have damaged pins.
5
Check cable integrity. Check the cables for
solid connections. Make sure they are screwed
down. Inspect cable ends for bent pins.
6
If termination is correct, and the problem
persists, try drives one at a time with different
cables, adding drives and cables until the
problem occurs. This helps pinpoint the drive or
cable causing the problem.
7
Check with the manufacturer of SCSI device(s)
for further troubleshooting methods.
If SCSI devices appear to be working, move on to
the iPBridge SCSI port section.
Checking the iPBridge SCSI ports
1
Verify the iPBridge has its termination set
properly. By default, termination is enabled.
2
Either through the ATTO ExpressNAV or CLI,
perform a SCSI bus scan on each SCSI port.
Refer to SCSI configuration commands on
page 47.
If no devices appear, re-check SCSI cables and
termination. If garbage information appears,
the problem is most likely a bad SCSI cable or
termination.
3
Check the internal cabling of the SCSI device.
LVD SCSI cable lengths are limited to 12.5
meters. Longer cable lengths can cause
problems. Internal cabling is also considered
when calculating total cable length. For details,
refer to Cabling on page iii.
4
Some older SCSI devices improperly negotiate
with the iPBridge SCSI port. If older devices are
28
not showing up, contact your service
representative.
5
If all devices appear, invoke the ScsiTargets
command several times on each SCSI port to
verify that the devices can be seen. If devices
disappear then appear again, the problem is
most likely a SCSI cable. For information on the
ScsiTargets command, refer to SCSI
configuration commands on page 47.
If all devices appear and remain, move to the
iPBridge internal configuration section.
When changing any setting on the iPBridge the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.
3
Verify that the Ethernet speed is set to auto:
invoke the get EthernetSpeed all command,
check the Ethernet page of the ATTO
ExpressNAV interface, or check the LED link
lights to determine if the Ethernet speed is
correct.
4
Determine if the iPBridge is set to get its IP
information from a DHCP server. If so, verify
that the DHCP server has available IP
addresses. Refer to Getting an IP address on
page 10.
5
Verify that each used Ethernet port on the
iPBridge can be pinged from the desired host.
Refer to Ping on page 52.
If the host cannot ping the iPBridge ports and
the iPBridge ports are properly configured,
continue to the Local Area Network/Wide Area
Network section, Checking the LAN/WAN on
page 29.
Checking the serial port
1
•
•
•
•
•
2
Verify you have the correct settings and that
your terminal is configured to:
Baud rate: 115200
Data bits: 8
Stop bits: 1
Parity: off
Flow control: None
6
Verify that your serial cable is less then two
meters in length.
If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
7
Some older switches/hosts cannot auto
negotiate between the iPBridge and the
switch/host at the desired speed. You may
have to force the host/switch or the iPBridge to
the desired speed.
8
Verify that the host is logging into the iPBridge
correctly by viewing the Connections page
and determining if there a “session open”
status.
9
Verify that you are using the correct log in
procedure for your initiator. For example: When
connecting using the Adaptec initiator, the log
on screen requests the iPBridge iqn (iSCSI
qualified name). If left blank, Adaptec cannot
log in. Enter “iSCSI” into this field for auto iqn
discovery.
Verify that each port on the iPBridge can ping
each desired host. Refer to Ping on page 52. If
the iPBridge cannot ping the host, continue to
Checking the LAN/WAN on page 29.
Checking the iPBridge internal
configuration
Verify that the SCSI devices are mapped properly.
Check in the ATTO ExpressNAV interface or use the
routedisplay iSCSI command to show mappings. If
devices do not appear, power down the iPBridge and
power back on. Refer to Mapping devices: NDMP on
page 13, Mapping devices: iSCSI on page 15 and
Mapping commands on page 57.
When changing any setting on the iPBridge, the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.
Checking iPBridge Ethernet ports
1
Check Ethernet cable integrity. Check the
cables for solid connections. Cat5 cable can
cause connection issues with Gigabit Ethernet.
Cat6 cable is the best cabling for the iPBridge.
2
Verify the IP address, subnet mask, and
gateway are properly set on each data port on
the iPBridge for your network environment.
Refer to Getting an IP address on page 10.
29
ATTO Technology Inc. iPBridge Installation and Operation Manual
When changing any setting on the iPBridge the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.
Checking the LAN/WAN
1
Verify that the switch/switches are segmented
properly so that hosts and the iPBridge have
access to each other.
2
If there are routers involved in the setup, make
sure the IP addresses and/or MAC addresses
of the iPBridge are allowed through the router.
3
Verify that the switch can see the iPBridge on
the port(s) in question. Refer to your switch
vendor’s guide for more information.
1
A PC using an iSCSI storage adapter and an
iSCSI OS driver might not work correctly on the
same machine. Check with the vendors to
make sure they are compatible.
2
Verify that the PC has the latest iSCSI driver as
well as the required service packs and patches.
Check with the iSCSI OS driver vendor for more
information.
3
Verify that the iSCSI OS driver has started.
Look under Device Manager for Windows or
lsmod for Linux.
4
Verify that the iSCSI OS is still looking for the
iPBridge at the right IP address.
5
If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
Refer to Ethernet Port Configuration on page
23.
6
Verify that the NIC is configured with the correct
IP information.
Checking the iSCSI Host Adapter or NIC
iSCSI host adapters appear as a type of Storage
Controller to the host OS, not as a standard NIC. These
adapters usually have hardware acceleration to offload
the TCP processing from the host. Configuration of
these adapters is usually done through the vendor’s
own utility and not through the OS itself.
NICs come in two types: accelerated and unaccelerated. Accelerated NICs use some hardware to
offload some of the TCP processing from the host. Unaccelerated NICs make the OS do all TCP processing.
To check the iSCSI host adapter or NIC
1
Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.
7
Verify that the hosts and the iPBridge are using
the same port number to communicate via
iSCSI. The default port number for the iPBridge
is 3260. Refer to iSCSIPortNumber on page 55.
2
Verify that the iSCSI host adapter or NIC is
configured with the correct IP information.
8
3
If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.
4
Verify that the hosts are running the
recommended driver and firmware level for the
iSCSI host adapter or NIC vendor.
5
6
7
Verify that the hosts and the iPBridge are using
the same port number to communicate via
iSCSI. The default port number for the iPBridge
is 3260. Refer to iSCSIPortNumber on page 55.
Make sure the host adapter/NIC is configured
to log into the iPBridge. Some iSCSI host
adapters do not re-login upon reboot or
unplug/replug event without marking a check
box.
Some older switches cannot autonegotiate
between the host and the switch properly. You
may have to force the host or switch to the
desired speed.
For a NIC using an OS iSCSI driver, continue to the
iSCSI OS driver section.
Checking the iSCSI OS driver
Checking the Operating System
1
Verify that the OS has the required service
packs or patches installed. If not, obtain the
proper service packs and patches and install
them.
2
Some iSCSI host adapters and iSCSI OS
drivers do not always automatically find new
targets when plugged in or when forced to
rescan. Reboot the hosts.
3
Check if the vendor has a new driver. If so,
install it.
Checking the applications
1
Verify that the application is running the latest
device drivers for the devices connected to
iPBridge. If not, get the latest device drivers and
install them.
2
Verify with the application vendor if the iSCSI
technology is supported on the version of the
application being used.
This section is for hosts using a driver that allows the
OS to talk to iSCSI targets via a NIC, not an iSCSI
storage adapter.
30
Performance issues
If the host is not getting the performance it should,
check the following items.
Checking the LAN/WAN
1
Checking SCSI devices
1
Verify that the devices are running at their
highest possible SCSI speed. Refer to SCSI
configuration commands on page 47.
Mixing SE and LVD devices on the same SCSI
bus forces the speed of the bus to SE, thus
slowing faster LVD devices. The iPBridge
cannot accelerate an already slow device.
Refer to Connecting SCSI devices to SCSI
ports on page iii of the Appendix.
2
1
Verify that the SCSI port configuration is set to
the highest speed using the ATTO ExpressNAV
interface or CLI. Refer to SCSI configuration
commands on page 47.
The iPBridge SCSI port speed, wide
negotiation, and sync negotiation settings all
affect the speed of the port. By default, these
settings are set for optimal speed.
2
9k frame size is the current optimized frame
size for the iPBridge. smaller frame sizes cause
a decrease in performance. Many switch and
router vendors do not support the larger frame
size of 9k or 16k.
2
Verify that the SCSI devices are equally
distributed between the SCSI ports. Refer to
Alternative interface options on page 33.
Optimal performance is seen when only two
high-speed SCSI devices are connected to
each SCSI port.
3
Verify that the data ports are set to auto
negotiate or forced to 1000 Mbs. Refer to
Ethernet Port Configuration on page 23.
2
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment.
Refer to Ethernet Port Configuration on page
23. The current optimized frame size for the
iPBridge is 9k. Smaller frame sizes cause a
decrease in performance.
3
Verify that the iPBridge TraceLog feature is
disabled. Tracelog tracks certain events that
occur in the iPBridge. With this log enabled,
performance suffers.
Refer to Diagnostic commands on page 43.
31
ATTO Technology Inc. iPBridge Installation and Operation Manual
Verify that packets are not being dropped along
the LAN/WAN. Many utilities track packet
activity and switch statistics.
Checking Ethernet Host Adapter or NIC
Ethernet Storage Adapters generally outperform
accelerated NICs and un-accelerated NICs by
offloading most of the processing from the host.
An accelerated NIC provides some offloading, but still
requires a host OS iSCSI driver, making the host spend
more CPU cycles.
An un-accelerated NIC does not offload anything so
the CPU must do much of the processing.
To check the Ethernet host adapter or NIC
1
Verify that the adapter or NIC is sent to autonegotiate or forced to 1000 Mbs.
2
Set the MTU size to the largest MTU size
supported in the LAN/WAN. Refer to Ethernet
Port Configuration on page 23.
Checking iPBridge Ethernet ports
1
Verify that each associated port in the IP SAN
is configured for 1000Mbs.
IP SAN traffic should be segmented so that it
does not interfere with the main LAN network
traffic.For better performance, the IP SAN
should be on its own set of hardware.
Verify that the proper terminator is being used.
An SE terminator forces the SCSI bus to SE
speeds.
Checking iPBridge SCSI ports
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment. Refer to
Ethernet Port Configuration on page 23.
9k frame size is the current optimized frame
size for the iPBridge. smaller frame sizes cause
a decrease in performance. Many switch and
router vendors do not support the larger frame
size of 9k or 16k. Set the maximum transfer
size to the most efficient size for the intended
target(s). For many tape drives, 64k is the
optimal setting.
Checking the applications
Some applications can be configured to change
transfer sizes. Configure the application for the
optimal size for the particular SCSI device(s)
connected to the iPBridge.
Checking the host system
The faster the host, the faster your transfer times are.
The work flow goes only as fast as the slowest
connection in the host system, so transferring data
from an IDE drive, 100Mb connection, a DLT 4000, a
high speed RAID volume across the country, or other
applications, slows the system no matter how fast
everything else is in the system.
1
Verify that the iSCSI storage adapter or NIC is
connected to the fastest PCI bus connector
supported by the adapter or NIC.
If the adapter supports PCI-X, place the
adapter in a PCI-X slot. If one is not available,
the host might not achieve the optimal
performance capable from the adapter.
Even placing a PCI-X adapter into a 64 bit 66
MHz slot loses performance. Some adapters
adjust clock speed depending on the speed of
the PCI slot into which they are plugged.
2
The host OS disk and swap disk/partition/file
should be on a high speed drive such as a SCSI
drive to minimize the time needed to access the
host’s virtual memory.
The more memory a system has, the less time
it spends accessing virtual memory (hard drive
space).
Checking the Operating System
If possible, eliminate swap space and virtual drives
which require large amounts of system memory.
However, the OS might not allow the elimination of
swap space. An OS set to run many kinds of different
servers spends much of its CPU cycle on other
operations, thus slowing down performance.
32
7 Alternative interface options
Alternative methods to using the ATTO ExpressNAV interface may be used to manage the iPBridge.
ATTO ExpressNAV is the recommended interface.
Use the serial port or header
1
Connect a cable from iPBridge RS-232 serial
port or header to the serial (COM) port on a
personal computer.
2
Turn on the iPBridge.
3
Start a terminal emulation program on the
personal computer, and use it to connect to the
iPBridge. For example, if you are using
HyperTerminal on a computer running a
Windows operating system,
4
a. Type iPBridge in the New Connection
dialog box.
b. Click OK.
c. In the Connect To dialog box, for the
Connect using field select the COM
port number to which your serial cable
is connected.
d. Click OK.
e. In the COM Properties dialog box
select the following values:
• Bits per second: 115200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None
• Terminal type: ASCII
• Echo: on
f. Click OK.
After you connect to the iPBridge, start-up
messages are displayed. These messages are
only displayed at start-up. The last line in the
start-up message sequence is Ready. See the
example in Exhibit 7.0-1 on page 34.
Note
In serial port sessions, there is no prompt on
the line below the word Ready. Begin typing
commands in the blank line where the cursor
is resting. No user name or password is
required for serial port access.
5
To verify that you have connected successfully,
type help after the Ready prompt and press
Enter.

Alternative interfaces
7.1 CLI provides ASCII-based interface
The command line interface (CLI) provides access to the ATTO iPBridge Services through a set of
ASCII commands. CLI commands may be entered while in CLI mode.
iPBridge Services provide configuration and
monitoring for the iPBridge. CLI commands may
be entered while in CLI mode or on the
ExpressNAV interface Advanced CLI page.
Note
The recommended management tool for the
iPBridge is ATTO ExpressNAV.
CLI commands are context sensitive and
generally follow a standard format
[Get | Set] Command [Parameter 1 |
Parameter 2]
followed by the return or enter key
CLI commands are case insensitive: you may type
all upper or all lower case or a mixture. Upper and
lower case in this manual and the help screen are
for clarification only.
Commands generally have three types of
operation: get, set and immediate.
The get form returns the value of a parameter or
setting and is an informational command.
Responses to get commands are specified in the
Results field for each command, followed by
Ready.
The set form is an action that changes the value of
a parameter or configuration setting. It may
require a SaveConfiguration command and a
restart of the system before it is implemented. The
restart can be accomplished as part of the
SaveConfiguration command or by using a
separate FirmwareRestart command. A number
of set commands may be issued before the
SaveConfiguration command.
Responses to set commands are either an error
message or Ready. *. The asterisk indicates you
must use a SaveConfiguration command to
finalize the set command. SaveConfiguration
asks if you want to restart the system or not.
Set commands which do not require a
SaveConfiguration command, defined as
immediate commands, are immediately executed.
Responses to Immediate commands are either an
error message or data results followed by Ready.
For an example of a typical CLI command and
response, see Exhibit 7.1-3 on page 38.

If a firmware restart is required to make the
requested change permanent, a prompt asks you to
confirm the restart. You can override this request by
indicating the override value on the command line.
You may make several changes through commands
and SaveConfiguration before implementing the
restart, but once you have restarted the iPBridge, all
the command changes created before the restart and

contain spaces if spaces are enclosed in quotation marks.
Entering the set iSCSIAlias command with no alias
parameter causes the alias to be removed.
Default: 0
Set syntax: set iSCSIAlias [Alias]
Requires a SaveConfiguration command
Get syntax: get iSCSIAlias
iSCSIChap
Enables/disables requiring CHAP (ChallengeHandshake Authentication Protocol) to be used for the
iSCSI protocol. If Multiple Target mode has been
enabled, a valid target name must be provided. If CHAP
is enabled, the target requires the initiator to negotiate
CHAP authentication using the CHAP secrets. An
initiator may reject this negotiation.
An in CHAP secret is for authentication of the server to
the iPBridge. The iPBridge can store up to 32 in secrets,
each with a unique Account Name (optionally the
Initiator Name) and secret pair. The Account Name can
be 1 to 223 characters. Account Names are case sensitive.
Account name can not be all.
An out chap secret is for authentication of the iPBridge
to the rest of the network. There can only be one out
secret. The account name is ignored for out secrets and
defaulted to root.
In multiple target mode, you may use discovery to
determine the Target Name.

for iSCSI connections. The port number must be between
1024 and 65535 except for port 860.
iSCSIChapSecret
Specifies the incoming and outgoing passwords for iSCSI
chap sessions. RestoreConfiguration default sets the
CHAP secret passwords pair to default values.
iSCSITarget
Creates/deletes an iSCSI target name. The target name
acts as a suffix to the standard bridge iSCSI-qualified
name. The target name may not exceed 24 characters. A
newly-created target has one LUN, the iPBridge LUN, at
LUN 0. If the target name already exists, this command
does nothing. Multiple Target mode must be enabled
to use this command. In verbose mode, overwriting a map
requires secondary confirmation of the action.
Secrets are case sensitive, 12 (16 for Microsoft iSCSI
initiator) to 32 characters, and cannot contain spaces. In
and out secrets must be different.
When either secret is all 0s, iSCSI CHAP authentication
is disabled. Additionally, an all ‘0’ secret can be
configured by entering the iSCSIChapSecret command
confirmation prompts with no parameters.

Appendix B Cabling
Additional information to physically connect ports to devices and to your SAN.
SCSI cabling
Examples
The SCSI specification limits total bus cable
length for single-ended SCSI in a non-UltraSCSI
environment to 3 meters (combined length of both
internal and external cable lengths).
In an UltraSCSI workgroup environment with a 7drive tower, you are limited to 1.5 meters between
the host and the tower, including the cabling for
the tower. If the 7-drive tower requires 1 meter of
cabling to connect all of its drives, the distance
from the tower to the host must be .5 meters.
Cables and devices must be chosen to maximize
performance and minimize the electrical noise
from the high-speed data transfers available with
the SCSI protocol. Cabling and termination
methods become important considerations for
proper performance. SCSI cables and devices are
subject to specific length and number limitations
to deal with electrical problems that arise at
increased operating speeds.
Cable types
Use high-quality cables rated for the type of SCSI
transfers required: well-insulated SCSI cables
ensure error free communications. Try to keep
cable lengths as short as possible to ensure higher
signal quality and performance.
Note
UltraSCSI is very sensitive to SCSI bus noise,
cable distances and the number of devices
connected on the SCSI bus. Carefully connect
your devices when working with UltraSCSI.

a certain number of devices.

Connecting SCSI devices to SCSI ports
ATTO iPBridge SCSI ports connect SCSI storage
devices to the network. Each SCSI port is
completely independent from the other SCSI port.
iii
ATTO Technology Inc. iPBridge Installation and Operation Manual
Each SCSI port is a bus capable of supporting 15
devices and each bus is capable of 40, 80 or 160
MB/sec. (Ultra, Ultra2 or Ultra3) transfer rates.
You may use externally provided striping
software to create a RAID 0 group that includes
devices from both SCSI busses to increase overall
performance.
Each SCSI bus auto-negotiates the appropriate
sync rates with the connected devices. If slower
devices are mixed with faster devices, the bus
communicates at the rate of the slowest device,
thus wasting the performance capabilities of the
faster devices. Connect slower devices to one
SCSI port and connect faster devices to the other
port.
The iPBridge supports a wide variety of SCSI
storage devices including stand-alone drives,
removable drives, JBODs, RAIDs, tape, CD and
DVD drives, changers and libraries.
1
Connect the cable from the SCSI device to a
VHDCI SCSI port on the iPBridge.
2
Check the type of cable, cable length limit and
number of devices recommended for the port.
See Exhibit 0.0-1.
Keep cable lengths as short as possible to
ensure the highest signal quality and
performance. These cable lengths include the
wiring inside the devices.
3
Set the IDs of the SCSI devices connected to
the bridge to a value other than 7.
Use a sequential ID starting at 0 for each
device. The SCSI port in the ATTO iPBridge
has an internal factory setting ID of 7, typical for
a SCSI initiator device.
Note
The entire SCSI bus operates at the speed of
the slowest device on that bus. If you wish to
mix devices of different SCSI speeds, place
the devices on separate busses. That is, put
the slower devices on iPBridge 2500 SCSI bus
0, and the faster devices on iPBridge 2500
SCSI bus 1. Each bus is independent so each
can operate at different speeds.
4
Terminate the SCSI bus after the last device.
The iPBridge is terminated internally.
Ethernet connections
Use at least Cat 5e cable to connect the Ethernet
ports to your network.
Note
For best performance, all cabling, network
interface cards (NICs), host bus adapters
(HBAs), and network switches must be Gigabit
Ethernet (GbE), and at least Cat 5e certified.
Most standard offices use 2-pair wiring which
is not compatible. GbE requires 4-pair wiring.
•
•
•
For best performance, support for 9014 byte
jumbo frames should be available for all switches
and host iSCSI equipment.
Before you begin installing the iPBridge Ethernet
ports, be sure to check or complete the following:
•
If you are managing your iSCSI system across a
WAN and your system uses a firewall, be sure
that the following ports are open and available:
telnet (port 23)
•
http (port 80)
•
ftp (ports 20 and 21)
•
iSCSI (port 3260)
ntp (port 123)
Be sure your host system(s) is set up and
configured.
•
Your host system can use any of three
different types of cards: a network interface
card (NIC), a telnet offload engine card
(TOE), or a storage network interface card
(SNIC).
•
The ATTO driver file from the CD included
with your iPBridge or from the ATTO
website, www.attotech.com, is installed on
your host.
•
The switch has been configured to forward
UDP broadcast messages.
•
The minimum requirement for Windows-based
browsers is Internet Explorer 5.5 or Netscape
Navigator 6.2. The minimum requirement for
Macintosh browsers is Internet Explorer 5.2 or
Safari 1.2.
•
Ethernet speed defaults to auto; the iPBridge
determines the speed and set other parameters
based on the speed.
If you are using the TCP protocol
•
iSNS (port 3705)
If you are using the UDP protocol
