X3T10 committee of ANSI (American National Standards Institute). For information on Fibre
Channel standards, refer to publications from the X3T11 committee of ANSI. For those who are
interested in purchasing approved American National Standards and Technical Reports, contact
ANSI at [phone].

25Network Storage Router e1200-160

Configuration Overview

Router Default Ethernet Settings

Some of the basic factory default values are:

■ IP address: http://1.1.1.1/

■ Subnet mask: 255.255.255.0

■ Gateway address: 0.0.0.0

■ User name: root

■ Password: password

HP recommends that you change these values from the defaults.
All settings within the router configuration are preset with default values. These

values are set to allow the router to be installed into most HP environments with
little or no configuration changes.

After changing the basic default values listed above, carefully consider any
additional configuration changes.

After the initial configuration of the router is established, HP recommends
backing up the configuration to an external file. If needed, during a recovery
process, this file can then be restored back onto the router.

26 Network Storage Router e1200-160

UI Overview

The router supports the following user interfaces:

■ Visual Manager

■ Serial

■ Telnet

■ FTP

Visual Manager

Visual Manager lets you view and change router configuration from any standard
Web browser. Information is dynamically generated in an HTML format so that
any Web browser can access it.

Unless the default values are used, the 10/100BaseT Ethernet port must be
configured using the serial port with an appropriate IP address, subnet mask, and
gateway prior to use.

For complete information on accessing and using Visual Manager, see Chapter 3,
"Visual Manager User Interface."

Configuration Overview

Serial

The serial port allows for configuration of device characteristics from a terminal
or terminal emulator. Multiple serial connections cannot be run at the same time.

For complete information on accessing and using the Serial UI, see Chapter 4,
"Serial/Telnet User Interface."

27Network Storage Router e1200-160

put and the get commands.

28 Network Storage Router e1200-160

Common Configuration Settings

To provide connectivity between hosts and devices, the router must establish an
address on each connected Fibre Channel network and SCSI bus. The following
paragraphs discuss configuration settings that are commonly modified and are
available in the Visual Manager UI and the Serial/Telnet UI.

For procedural information on accessing and changing these settings, see Chapter
3, "Visual Manager User Interface," and Chapter 4, "Serial/Telnet User Interface."

Controller LUN Commands

The router supports a set of SCSI-3 commands that can be received as FCP
commands over the Fibre Channel port. These commands provide support for
value added features such as Extended Copy (a future value added option). When
using these commands, they must be sent to the Controller LUN.

For more information, see Appendix B, "Controller LUN Commands."

SCSI Bus Configuration

The router can appear on a SCSI bus as a pair of initiators. The primary Initiator
ID can be set to any valid SCSI address (0-15) and is used for most traffic. The
alternate Initiator ID can also be set to any valid SCSI address (0-15) and is for
use with high priority traffic. The Initiator IDs (primary and alternate) should not
be set to the same SCSI address and no other devices on the SCSI bus may use
either of these SCSI addresses.

The router can also appear as one or more Target ID on a SCSI bus. By default, no
Target IDs are set up.

The router provides the capability to reset SCSI buses during the router boot
cycle. This allows devices on a SCSI bus to be in a known state. The reset option
can be enabled/disabled during configuration of the router. The SCSI bus reset
feature is enabled in the default configuration, but should be disabled for
configurations using multiple initiators, tape changers or other devices that have
long reset cycles, or for environments that are adversely affected by bus resets.

Configuration Overview

The router negotiates the maximum values for transfer rates and bandwidth on a
SCSI bus. If an attached SCSI device does not allow the full rates, the router will
use the best rates it can negotiate for that device. Because negotiation is on a
device-specific basis, the router can support a mix of SCSI device types on the
same SCSI bus.

29Network Storage Router e1200-160

Configuration Overview

Fibre Channel Port Configuration

By default, the configuration of the Fibre Channel ports is set to N_Port, forcing
the router to negotiate a fabric only mode.

Note: By default, the Fibre Channel port speed is set to 2 Gb/s. Changes to the Fibre

Channel port speed must be manually set, such as for 1 Gb/s. If set incorrectly and the
router is plugged into a Loop or Fabric, the unit may receive framing errors, which can be
found in the trace logs, and the fiber link light will be off because of the incorrect Fibre
Channel link speed. For more information on manually setting the Fibre Channel port
speed, see Chapter 3, "Fibre Channel Port Configuration."

Fibre Channel Switched Fabric Configuration

When connected to a Fibre Channel switch, the router is identified to the switch as
a unique device by the factory programmed World Wide Name (WWN).

Discovery Mode

This feature makes it easy to discover attached Fibre Channel and SCSI target
devices and automatically map them on the host side for the bus/port in question.

There are two discovery methods available:

■ Manual discovery

■ Auto discovery

Auto Discovery can be set to occur after reboot events (when the router reboots)
or link-up events (for instance, when cables are attached or a hub is rebooted).
Auto Discovery can be disabled by setting the router to Manual Discovery.

For more information on setting the Discovery Mode, see Chapter 3, "Fibre

Channel Port Configuration," when using the Visual Manager User Interface or

Chapter 4, "Fibre Channel Configuration," when using Serial/Telnet.

Host Device Configuration

A host system using a Fibre Channel Host Bus Adapter (HBA) will typically map
devices into the existing device-mapping scheme used by that operating system.
Refer to the HBA manual for the mapping table.

30 Network Storage Router e1200-160

Configuration Overview

Mapping involves pairing FC_AL_PA to SCSI target address. The HBA will
claim enough SCSI bus entries to allow up to 125 Fibre Channel targets to be
mapped to SCSI Bus: Target entries. This is usually done by a fixed mapping of
AL_PA to Bus: Target. In such a configuration, the router corresponds to a
Bus: Target identifier, with the attached SCSI devices appearing as logical units
(LUNs). Operating systems can extend the available SCSI limit of 15 targets per
bus. Although this is not an issue for the operating system or most applications,
there are cases where older applications can have expectations about what
constitutes a valid SCSI ID, and thus may not correctly handle certain mappings.
In particular, some applications may exhibit difficulties addressing target IDs
greater than 15 (for example, 16 and up). This situation can be resolved by
configuring the router to use hard addressing and setting the AL_PA to a value
less then 16 that the HBA will be able to map.

For example, depending on the Fibre Channel HBA, if the hard AL_PA selection
is 1, then the address is 1. If the selection is 125, the AL_PA address is 0xEF.
Some Fibre Channel HBAs will map devices differently, so verify the AL_PA by
reviewing the documentation for the HBA.

For more information on AL_PA configuration, see Chapter 3, "Fibre Channel

Port Configuration," when using the Visual Manager User Interface or Chapter 4,

"Fibre Channel Configuration," when using Serial/Telnet.

Logical Unit Management

Because SAN resources can be shared, it is possible for multiple hosts to have
access to the same devices on the SAN. To prevent conflicts, the router provides
LUN management as a means to restrict device access to certain hosts. LUN
management goes beyond simple LUN masking, to prevent gaps in the list of
LUNs presented to a host.

LUN management maps can be created for different views of the devices attached
to the router. Each Fibre Channel host is assigned a specific map configuration.
Not only can the administrator control which devices a host may access, but also
which LUNs are used to access these devices.

For a Fibre Channel host, a map is a table of LUNs, where each entry is either
empty or contains device address information needed for host/device
communication.

For a SCSI host, a map contains a list of target IDs, each of which has its own
table of LUNs with address information needed for host/device communication.

31Network Storage Router e1200-160

Configuration Overview

Note: The router can respond to multiple Target IDs on a SCSI bus.

Both Fibre Channel ports and SCSI buses have predefined maps.
There are four predefined maps:

■ Indexed Map

■ Port 0 Device Map

■ Auto Assigned Maps

■ SCC Map

When a host sends a command, the router will select which map to use, based on
the port receiving the command and the ID of the host sending the command. For
Fibre Channel ports, the host ID is the World Wide Name; for SCSI buses, the
host ID is the Initiator ID (0 - 15). When a host is unknown or is not assigned a
specific map, the router will use the default map.

Indexed Map

An indexed map is initially empty.

Port 0 Device Map

The Port 0 Device Map should be used when editing and assigning oncoming
hosts.

Auto Assigned Map

An auto assigned map is built dynamically and contains all of the devices found
during discovery. This map will change automatically any time the discovery
process finds a change in the devices attached. This map cannot be modified by
the user.

SCC Map

An SCC map is only available on Fibre Channel ports and contains only a single
entry for LUN
is managed using SCC logical unit addressing.

32 Network Storage Router e1200-160

0. This LUN is a router controller LUN. Access to attached devices

Buffered Tape Writes

This option is designed to enhance system performance by returning status on
consecutive write commands prior to the tape device receiving data. If data does
not transfer correctly, the router returns a check condition on a subsequent
command.

Commands other than Write are not issued until status is received for any pending
Write, and status is not returned until the device completes the command. This
sequence is appropriate for tasks such as file backup or restore.

Some applications require confirmation of individual blocks being written to the
medium, such as for audit trail tapes or log tapes. In these instances, the Buffer
Tape Writes option must be disabled.

Visual Manager User Interface

Visual Manager Access

Visual Manager (VM) can be accessed from any standard Web browser:

1. Connect a 10/100BaseT Ethernet cable to the back of the router.

2. Apply power to the connected SCSI and/or Fibre Channel devices.

3. Apply power to the host computer.

4. Enter the router IP address in the address field of the Web browser of the host
computer.

Note: To access VM, the router must be assigned a valid IP address. The factory default

setting for the IP address allows access on a local area network only. If the factory default
for the IP address is already used by another device on the local network, the IP address
must be changed.

The factory default for the IP address is http://1.1.1.1/

Note: If the IP address of the router is not known or needs to be changed, connect to the

router using a serial connection. The current router IP address is displayed and can be
changed in the serial Ethernet Configuration Menu.

The Visual Manager home page is displayed, showing router status
information. The home page is accessible to anyone who knows the router IP
address.

5. Select the desired menu option to access menus and screens.
The Password dialog box is displayed. See Figure 7 for an example of the

Password Dialog box.

38 Network Storage Router e1200-160

Visual Manager User Interface

6. Enter the authorized user name and password. The username and password
are case-sensitive.

The default user name is root and the default password is password.

Figure 7: Password Dialog Box

Note: HP recommends changing the user name and password from the defaults.

Note: To end the current session of VM, the browser window must be closed.

Navigating the browser to another URL does not end the current session.

39Network Storage Router e1200-160

Visual Manager User Interface

Visual Manager Best Practices

The following recommendations should be observed:

■ A standard keyboard and mouse must be used to navigate in the VM.

■ The router is shipped with a configuration of default settings that is acceptable

for most system environments. Few changes to the configuration should be
necessary.

■ After any configuration changes are made, depending on the menu option,

select Submit or Configure to send changes from the Web browser to the
router.

Changes will take effect during the next router reboot cycle.

■ If the configuration has been modified to meet specific needs, back up the

configuration to an external file. If necessary, these settings can later be
restored to the router.

■ Except for the user name, password, and override access, fields are not

case sensitive.

■ HP recommends that you not bookmark VM pages with the Web browser.

Because configuration information is transmitted via URLs, it is possible that
the router could be configured with information present at the time a page was
bookmarked.

■ HP recommends navigating using only the Web page links contained in VM

itself.
Depending on the Web browser used, these links will often appear as

highlighted text. By selecting these links, VM can be safely navigated.

40 Network Storage Router e1200-160

Main Menu

Port Configuration - Ethernet Settings (Service Mode - Restricted Access)

To change the Ethernet configuration settings, select the Ethernet port icon. The
Ethernet Configuration dialog box is displayed.

See Figure 14 for an example of the Ethernet Configuration dialog box.

Figure 14: Ethernet Configuration dialog box

Ethernet configuration settings:

■ Ethernet Mode can be set to one of the following options:

—10Mps Only
— 100Mps (half duplex) Only
— 100Mps (full duplex) Only
— 10/100Mps (Auto-Neg.)

■ MAC address is the Ethernet physical address of the router.

Caution: If this configuration is incorrectly set, processing difficulties may occur.

Before changing this setting, evaluate the need for the change and verify the
desired setting. HP recommends backing up the router configuration to an
external file before making changes to this setting.

48 Network Storage Router e1200-160

Visual Manager User Interface

The Ethernet physical address is always assigned by the manufacturer.

■ IP address (default: 1.1.1.1) is the IP address of the router.

■ Subnet Mask (default: 255.255.255.0) is the IP subnet mask for the router.

■ IP Gateway (default: 0.0.0.0) is the IP address of the gateway for the Ethernet

network connected to the router.

■ DHCP enables or disables support for Dynamic Host Configuration Protocol

(DHCP).
When DHCP is enabled, the router requests a dynamic IP address from a

DHCP server on the Ethernet network. The router must be rebooted before an
IP address will be requested from the DHCP server. After the router is
rebooted, the HTTP session must be restarted. The IP address will be different
from the former non-DHCP IP address.

Note: To use the DHCP feature, a DHCP server must be operational on the Ethernet

network. If the DHCP feature is used when there is not DHCP server, the standard for
DHCP requires the router wait thee minutes for a response from a DHCP server before
timing out.

Some DHCP servers allow a lease reservation to be set up for an IP address by
providing the server with the Ethernet MAC address. The DHCP server
always provides the same IP address to the router. This setup can be useful for
remote management of the router via Telnet or VM. Because the method of
setting up a lease reservation varies, depending on the DHCP server being
used contact the Network Administrator for assistance.

SNMP Configuration

SNMP configuration is not supported.

49Network Storage Router e1200-160

56 Network Storage Router e1200-160

Visual Manager User Interface

Caution: If the following configuration settings are incorrectly set, processing

difficulties may occur. Before changing these settings, evaluate the need for
the change and verify the desired setting. HP recommends backing up the
router configuration to an external file before making changes to these
settings.

■ Port Name Low sets a new value for the World Wide Port Name High.

(Service Mode - Restricted Access)

■ Port Mode (default: N_Port) sets the port mode.

Port Mode settings:
— Auto Sense: In this mode, the Fibre Channel port tries to negotiate as a

loop. If it is not successful, then the Fibre Channel port negotiates as a
fabric. If the port comes up as a loop, it then determines whether it is on a
private or public loop.

— N_Port: (default) This mode allows the router to bypass the loop

negotiation and come up as a fabric only. If the router is on a loop, and
N_Port mode is selected, an error in communication may occur.

■ Use Hard AL_PA enables or disables Hard AL_PA usage.

■ Hard AL_PA Settings displays the AL_PA Lookup Table.

Use the table to find the node number. This unique one-byte valid value
(derived from an Arbitrated Loop Topology defined in ANSI specification
FC_AL version 4.5) is used for the Fibre Channel configuration.

■ Discovery Mode (default: Manual Discovery Only) determines how the

router will discover new Fibre Channel devices.
Discovery mode settings:
— Auto Discovery on Reboot Events allows the router to automatically

discover all Fibre Channel devices when rebooted or when link-up events
occur, such as connecting cables or rebooting network hubs.

— Both the ports and the devices behind the ports are discovered on all

subsequent link-up events.

— Auto Discovery on Link Up Events allows the router to automatically

discover all Fibre Channel devices when rebooted or when link-up events
occur, such as connecting cables or rebooting network hubs.

— Both the ports and the devices behind the ports are discovered for the first

link-up event. Subsequent link-up events will only discover the ports and
not the devices behind the ports.

57Network Storage Router e1200-160

Visual Manager User Interface

— Manual Discovery Only (default) sets discovery of new devices to occur

Note: SCSI devices attached to a Fibre Channel must be mapped as sequential Fibre

Channel LUNs starting at LUN number 00. Skipping LUN numbers is not
recommended when mapping Fibre Channel LUNs because Fibre Channel Discovery
stops the discovery process whenever an empty LUN position is found.

■ Buffered Tape Writes (default: enabled) enables or disables the Buffered

Tape Write option.

When enabled, to enhance performance, Buffered Tape Writes return status
on consecutive write commands prior to the tape device receiving data.

only after the user selects the Discovery option from the Main Menu or
when a Registered State Change Notification (RSCN) is received from a
fabric.

Caution: If this configuration setting is incorrectly set, processing difficulties

may occur. Before changing this setting, evaluate the need for the change
and verify the desired setting. HP recommends backing up the router
configuration to an external file before making changes to this setting.

■ Buffered Tape Queue Depth sets the Buffered Tape Queue Depth.

Select a setting of 0 through 10 from the drop-down list.

■ Default Map (default: indexed) sets the current mapping mode for the

selected port.
The current map can be set to:
— Port 0 Device Map (HP recommends that this map be used to edit and

assign oncoming hosts.)

— Indexed (default) (HP recommends that this map NOT be edited, even

though the user is able to edit the Indexed map.)

— Auto-assigned contains all the SCSI devices that are attached to the

router.
—SCC
For more information about mapping modes, see Appendix C, "Addressing

Methods and Table Structures."

For information on changing map settings, see “Mapping Menu, page 65,”

■ Performance Mode (default: 2 Gb/s) toggles between 1 Gb/s and 2 Gb/s.

Note: If Performance Mode is set incorrectly and the router is plugged into a Loop or

Fabric, the unit may receive Framing errors due to the incorrect Fibre Channel link
speed.

■ Override Settings (service mode-restricted access) enhances interoperability

with some storage devices that require special consideration during setup of
the router configuration menus.

— Hi-Sup Bit toggles between Set and Clear.
— Force FCP Response Code toggles between Off and On for support of

HP-specific HBA #223180-B21 and #120186-001.

may occur. Before changing this setting, evaluate the need for the change

and verify the desired setting. HP recommends backing up the router

configuration to an external file before making changes to this setting.

Note: Target IDs must be setup before mapping devices on the SCSI bus.

Note: Do not enable Target IDs unless there is a SCSI initiator on the bus that wants to

use Fibre Channel devices. This type of configuration is known as a Target Mode
configuration.

■ Discovery toggles between Enabled and Disabled.

■ Discovery Delay is the wait time after a power-up or reboot before

discovering SCSI devices.

Note: HP recommends setting the value to at least 30 seconds to ensure all SCSI

devices complete their individual power-ups.

■ Bus Reset on Boot toggles between Enabled and Disabled.

When enabled, the router will automatically reset SCSI buses during a power
up or reboot of the router.

■ Internal Termination toggles between Enabled and Disabled.

Caution: If this configuration setting is incorrectly set, processing difficulties

may occur. Before changing this setting, evaluate the need for the change

and verify the desired setting. HP recommends backing up the router

configuration to an external file before making changes to this setting.

When enabled, internal termination of the selected SCSI bus is allowed.
When disabled, the SCSI Bus, not the router handles SCSI termination.

■ Buffered Tape Writes (default: Enabled) toggles between Enabled and

The Serial/Telnet User Interface (UI) is used to configure and manage the HP
StorageWorks Network Storage Router. This chapter describes the configuration
menus and option tasks available in the Serial/Telnet UI.

Note: Unless otherwise indicated, configuration changes take effect when the router

reboots.

During the router start up process, the Serial/Telnet UI displays initial power-up
messages. After the power-up process is completed, the Main Menu of the UI is
displayed. Within the router Main Menu, several configuration menus and tasks
are listed. All configuration and management tasks are performed from these
menus.

Telnet UI Access

To open a Telnet session, the IP address of the router and a Telnet client utility are
required.

Note: After each reboot, a new Telnet session must be started. If the router is reset to

factory settings, the Ethernet port will have to be re-configured using the serial
interface.

From most Windows 9x, Windows NT, and Windows 2000 systems, a Telnet
session can be started from the Command (DOS) shell using the following steps:

1. From the Windows Start Menu, open the Command Prompt (DOS) window.

2. At the ‘>’ prompt, enter:

where <IP ADDRESS> is the IP address of the router

3. Enter the user name and password.
The default user name is root and the default password is password.
HP recommends that the user name and password be changed from the default

values. The Configuration Menu is displayed.

> TELNET <IP ADDRESS>

Serial UI Access

To open a serial session, a terminal emulator utility is required.
From most Windows 9x, Windows NT, and Windows 2000 systems, a

HyperTerminal session can be started using the following steps:

1. From the Windows Start Menu, open HyperTerminal.

2. Name the new terminal session.

3. Indicate the appropriate COM port.

■ 1) Baud Rate Configuration changes the baud rate on the serial port.

■ 2) Ethernet and SNMP (SNMP not supported) Configuration enters

Ethernet network settings.

■ 3) Fibre Channel Configuration configures the settings for the Fibre

Channel port.

■ 4) Parallel SCSI Configuration configures the settings for the SCSI buses.

To view or change configuration settings:

1. Select a menu option

2. Make the configuration changes

3. Select X) Return to previous menu

4. Select A) Save Configuration to record the changes.

Ethernet Configuration Menu options:

■ 1) Change IP address (default: 1.1.1.1) changes the router IP address.

■ 2) Change IP Subnet Mask (default: 255.255.255.0) changes the router

Subnet mask.

■ 3) Change IP Gateway (default: 0.0.0.0) changes the IP gateway for the

Ethernet network.

■ 4) Change Ethernet Physical Address changes the Ethernet physical

address (MAC address).

Caution: If this configuration setting is incorrectly set, processing difficulties

may occur. Before changing this setting, evaluate the need for the change
and verify the desired setting. HP recommends backing up the router
configuration to an external file before making changes to this setting.

The manufacturer always assigns Ethernet physical addresses to the Ethernet
adapters.

■ 5) Toggle Ethernet Mode changes the Ethernet mode.

Options include:
— 10 Mb/s only
— 100 Mb/s (half duplex) only
— 100 Mb/s (full duplex) only
— 10/100 MPS (Auto-Neg.)

■ 6) Change Hostname changes the name of the host server.

The name can be any combination of alphanumeric characters, up to eight
characters.

99Network Storage Router e1200-160

Serial/Telnet User Interface

■ 7) Toggle DHCP Configuration enables or disables support for Dynamic

Configuration Protocol.
When DHCP is enabled, the router will request a dynamic IP address from the

DHCP server on the Ethernet network.
Some DHCP servers allow a lease reservation to be set up for an IP address by

providing the server with the Ethernet MAC address. The DHCP server will
then always provide the same IP address to the router. This setup can be
useful for remote management of the router such as Telnet or Visual Manager
Because the method of setting up a lease reservation varies depending on the
DHCP server being used, contact your Network Administrator for assistance.

Note: To use the DHCP feature, a DHCP server must be operational on the Ethernet

network. If the DHCP feature is used when there is no DHCP server, DHCP standards
require the router wait three minutes for a response from a DHCP server before timing
out.

■ 8) Change SNMP Settings is not supported.

■ 9) Change Security Settings changes security settings, including the user

name and password.
The default user name is root and the default password is password.

Caution: To ensure security, change the user name and password from the

default settings.

Note: The security settings entered here affect all user interfaces.

User names and passwords should be unique and kept confidential. HP
recommends using a combination of letters and numbers when creating user
names and passwords.
