Note: Before attempting to configure the router, a basic understanding of Fibre Channel and

SCSI devices is recommended. For information on SCSI standards, refer to publications from the
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].

27Network Storage Router N1200 User Guide

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.

28 Network Storage Router N1200 User Guide

UI Overview

The router supports the following user interfaces:

■ Visual Manager, page 29

■ Serial, page 29

■ Telnet, page 29

■ FTP, page 29

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 “Visual

Manager User Interface” on page 37.

Configuration Overview

Serial

Telnet

FTP

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 “Serial/Telnet

User Interface” on page 87.

From most Microsoft® Windows® 9x, Windows NT®, and Windows 2000®
systems, users can start a Telnet session from the DOS (command) shell after the
IP address has been set.

For complete information on accessing and using the Telnet UI, see “Serial/Telnet

User Interface” on page 87.

The router supports the use of the FTP UI to perform several copy procedures
using the

put and the get commands.

30 Network Storage Router N1200 User Guide

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 “Visual Manager User

Interface” on page 37 and “Serial/Telnet User Interface” on page 87.

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. When using these commands, they
must be sent to the Controller LUN. For more information, see Appendix B,
“Controller LUN Commands” on page 161.

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.

Configuration Overview

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.

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.

31Network Storage Router N1200 User Guide

Configuration Overview

Fibre Channel Port Configuration

By default, the configuration of the Fibre Channel ports is set to N_Port, forcing
the router to configure as an Arbitrated Loop.

Note: By default, the Fibre Channel port speed is set to 1 Gbps. Changes to the Fibre Channel

port speed must be manually set, such as for 2 Gbps. If set incorrectly and the router is plugged
into a Loop or Fabric, the unit may receive framing errors because of the incorrect Fibre
Channel link speed.

Fibre Channel Arbitrated Loop Configuration

On a Fibre Channel Arbitrated Loop, each device appears as an Arbitrated Loop
Physical Address (AL_PA). To obtain an AL_PA, two methods can be used:

■ Soft Addressing

■ Hard Addressing

Soft addressing is the default setting.

Soft Addressing

During soft addressing, the router automatically acquires the first available loop
address, starting from 01 and moving up to EF. The router may participate on the
Fibre Channel loop as long as there is at least one address available on the loop
connected to the router. Fibre Channel supports up to 126 devices on an
Arbitrated Loop.

Hard Addressing

During hard addressing, the router attempts to acquire the AL_PA value specified
in the configuration settings. If the desired address is not available at loop
initialization time, the router negotiates the next available soft address. This
allows both the loop and the router to continue to operate.

Hard addressing is recommended for Fibre Channel Arbitrated Loop
environments where it is important that the Fibre Channel device addresses do not
change. Device address changes can affect the mapping represented by the host
operating system to the application, and have adverse effects. An example is tape
library installation, where the application configuration requires fixed device
identification for proper operation.

32 Network Storage Router N1200 User Guide

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.

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.

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.

Configuration Overview

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.

33Network Storage Router N1200 User Guide

Configuration Overview

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.

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

Both Fibre Channel ports and SCSI buses have user-defined maps and predefined
maps.

There are three predefined maps:

■ Indexed Maps

■ Auto Assigned Maps

■ SCC Maps

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 Maps

An indexed map is initially empty and can be modified by the user.

34 Network Storage Router N1200 User Guide

Auto Assigned Maps

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 Maps

An SCC map is only available on Fibre Channel ports and contains only a single
entry for LUN 0. This LUN is a router controller LUN. Access to attached devices
is managed using SCC logical unit addressing.

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.

Configuration Overview

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 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 company-specific needs, back

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

■ Except for the user name, password, and override settings, 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.

■ 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).

48 Network Storage Router N1200 User Guide

Visual Manager User Interface

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.

■ 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.

97Network Storage Router N1200 User Guide

Serial/Telnet User Interface

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.

Note: Be sure to correctly set the clock and date in the Real Time Clock Configuration

Menu so that event logging is accurate.
