when the network storage router detects a fault condition.

• Fibre Channel LNK/ACT– When green, the LNK indicator signifies a good Fibre Channel link. When

green, the ACT indicator signifies Fibre channel port activity.

• SCSI bus (0, 1) – When lit, these green indicator LEDS signifiy SCSI activity for the associated bus.

• Ethernet (10/100) – The LNK indicator (left) will stay permanently lit to indicate an Ethernet link. The

ACT indicator (right) should flash to indicate Ethernet activity.

10 Introduction

How the HP N1200-320 4Gb Network Storage Router works

The network storage router is a device that translates the Fibre Channel Protocol (FCP) to and from the SCSI Protocol—transparently transferring commands, data, and status information—so that both the Fibre Channel (FC) and SCSI devices and hosts can communicate with each other. Interconnection is provided between two SCSI buses and one Fibre Channel Arbitrated Loop or Switched Fabric, making use of Fibre Channel’s ability to encapsulate SCSI protocol packets.

Processing SCSI information

The following section describes how the network storage router processes SCSI information when attached to FC hosts.

1. A FC host issues a command, then encapsulates the command in the FC protocol and sends the packet

to the network storage router.

2. The network storage router receives the packet, interprets the FC information, and places the packet in

buffer memory.

3. The processor interprets the information and programs an internal SCSI controller to process the

transaction.

4. The SCSI controller sends the command to the SCSI device (target).

5. The SCSI target interprets the command and executes it.

6. Data flows between the FC host and SCSI target through payload buffers.

7. Response information flows from the SCSI target back to the FC host.

Connect the power cord

IMPORTANT: Before supplying power to the network storage router, HP recommends setting up serial port

communications with your host computer, unless serial I/O was previously established and is currently running (see ”Setting up serial port communications” on page 18).

IMPORTANT: The power cord shipped with the network storage router is a 120 VAC three-conductor

power cord for use in the United States and Canada. If the router is being installed outside the United States or Canada, the appropriate power cord should be purchased.

Connect the power cord to the power connector on the back of the router. Connect the other end of the power cord to a grounded voltage source.

Figure 9 Power cord connection

N1200-320 4Gb Network Storage Router user and service guide 17

Setting up serial port communications

The network storage router is designed to communicate with a terminal or any operating system utilizing a terminal emulator. For example, most Windows

operating systems can use a terminal. Be sure the

baud rate, data bits, stop bits, parity, and flow control are set correctly.

To set up serial communications with the network storage router:

1. Plug the serial cable into one of the host computer’s serial ports (COM1 or COM2), and then plug the

other end of the serial cable into the network storage router’s serial port (see Figure 2 on page 9).

2. Start the terminal emulator.

3. Set the terminal emulator to use the appropriate COM port.

4. Specify the following settings for the port:

Baud Rate: 9600, 19200, 38400, 57600, or 115200

(Autobaud only recognizes these baud rates)

Data Bits: 8

Stop Bits: 1

Parity: None

Flow Control: None or XON/XOFF

NOTE: Before initially applying power to the network storage router, make sure all the SCSI devices are

powered on first, and that they have finished performing individual self tests. This helps to ensure that device discovery works correctly.

5. Apply power to the network storage router. The power-up process can take up to 90 seconds. Once

complete, the main menu should be accessible.

NOTE: Refer to the HP StorageWorks MSL2024 or the MSL4048 Tape Library User and Service Guide for

detailed tape library information.

Interfaces and connections

There are four types of interfaces to the network storage router:

• Fibre Channel

• SCSI

• 3-pin serial port

• Ethernet

The 3-pin serial and Ethernet ports are used for configuration and management of the network storage router.

For convenience in configuring ports, key information is indicated on the back panel of the network storage router such as WWN name, WWP name, and Ethernet MAC ID (Physical Address).

Fibre Channel connections

Before connecting the network storage router to other devices, it is important to understand the configuration requirements of the environment to which it is connected.

IMPORTANT: Failure to correctly configure a Fibre Channel device may impair the operation of the

Storage Area Network (SAN) to which it is attached.

Typical installations have the network storage router connected to a Switched Fabric environment. For an Arbitrated Loop, the unit can be directly attached to the Fibre Channel host bus adapter. In Fibre Channel switched environments, the switch is also directly attached to the network storage router.

Both FC switches and hubs may allow for individual ports to be configured for different media types. The network storage router must be connected to the hub or switch port with the appropriate FC cabling for the media type in use on both the network storage router and the port to which it is connected.

The network storage router supports various Fibre Channel media types through the use of external Small Form Factor Pluggable Transceivers (SFPs).

Supported media type: Multi-Mode Fiber - 4.25 Gbit Dual LC connectors.

To connect the network storage router to the Fibre Channel SAN:

1. Locate the Fibre Channel port on the network storage router (see Figure 2 on page 9).

2. Remove the rubber protector from the SFP.

3. With the network storage router powered off, connect the router into the Fibre Channel environment

using the appropriate cabling. The FC optical connector on the network storage router is keyed. Be sure to insert the cable connectors in the proper orientation.

N1200-320 4Gb Network Storage Router user and service guide 19

SCSI connection

CAUTION: SCSI ports on the network storage router are not hot-pluggable. Power off the network

storage router whenever connecting/disconnecting the SCSI cables.

The network storage router can support Fast/Ultra320 Narrow/Wide SCSI, depending on the specific configuration. The network storage router is factory configured to support LVD/Single-Ended buses. Two VHDCI 68-pin D-shell, P-type connectors are available, allowing the unit to be attached at the end of up to two SCSI buses. The network storage router must always be installed at the end of SCSI buses.

The network storage router supplies termination power (TERMPWR) to each SCSI bus. An internal self-resetting fuse in the TERMPWR resets after a fault is cleared.

CAUTION: Do not plug HVD devices to an LVD/SE bus. Failure to follow this caution may result in severe

damage to equipment.

To connect the network storage router to a SCSI bus:

1. Power off the network storage router.

2. Power off the SCSI devices on this bus.

3. Connect a SCSI cable to one of the SCSI connectors on the router. The network storage router should

always be installed at the end of the SCSI bus.

4. Make sure that the bus is terminated correctly. By default, the network storage router is automatically

terminated. However, the device at the other end of the bus must also be terminated.

Ethernet connection

A 10/100BaseT Ethernet connection provides management and configuration access. The RJ-45 connector on the unit can be directly connected to a standard 10/100BaseT Ethernet network.

NOTE: You should change the pre-filled in settings if you disable DHCP, because while they are valid

settings, a conflict occurs if more then one network storage router is on the network with these initial settings.

Setting the IP network address is recommended, but not required, in order to configure the network storage router from this port. The IP network address can be manually assigned or dynamically assigned (using DHCP). The default network configuration is DHCP, but if DHCP is turned off, the initial value for the IP address is 1.1.1.1, the Subnet is 255.255.255.0, and the Gateway is 0.0.0.0.

Depending on the network environment, you may be able to temporarily use the IP address of 1.1.1.1 to configure the network storage router. For more about the IP network address, refer to ”Network

configuration” on page 36.

Ethernet capabilities include Telnet support for configuration and management and FTP support for other management capabilities.

20 Installation, cabling, and setup

Serial port connection

The 3-pin connector on the network storage router provides a serial port that is compatible with RS-232 signaling levels. The network storage router is designed to communicate with a terminal or any operating system using a terminal emulator. The baud rate, data bits, stop bits, parity, and flow control of both the network storage router and the host system must use the same settings. The Autobaud feature described below provides an effective method to set the baud rate of the network storage router and host system.

Autobaud feature

The Autobaud feature automatically configures the baud rate on the network storage router. Once you set the baud rate in the terminal emulator, wait until the network storage router completes the Power-On Self Test (POST) and then the firmware initialization process. This can take up to 90 seconds, during which time the POST and initialization information may or may not be visible on the terminal or terminal emulator. After this process has completed, you can press the Enter key slowly seven or eight times (or just type shift-z) and the network storage router automatically detects the baud rate being used by the serial port. The baud rate is then saved in the network storage router’s configuration and is retained through future power cycles.

NOTE: Pressing the Enter key before the POST has completed is of no benefit to the Autobaud feature.

Wait at least 90 seconds until both the POST and the firmware Initialization processes have completed before pressing the Enter key.

NOTE: If there is no response using the Enter key, press the space bar slowly seven or eight times, and

then press the Enter key slowly seven or eight times.

The baud rate used by the terminal or terminal emulator must be 9600, 19200, 38400, 57600, or 115200 for the Autobaud feature to recognize it. The network storage router does not function properly at any other baud rate.

22 Installation, cabling, and setup

3 Device management

To provide connectivity between hosts and devices, it is necessary for the network storage router to be recognized with an address on the connected Fibre Channel network.

SCSI bus configuration

The network storage router provides the capability to reset SCSI buses during the network storage router boot cycle. This allows the devices on a SCSI bus to be set to a known state. Configuration provides for the SCSI bus reset feature to be enabled or disabled.

The network storage router negotiates for the maximum values for transfer rates and bandwidth on a SCSI bus. If an attached SCSI device does not allow the full rates, the network storage router uses the best rate it can negotiate for that device. Negotiation is on a device specific basis, so the unit can support a mix of SCSI device types on the same SCSI bus.

FC port configuration

By default, the configuration of the FC port on the network storage router is set to N_Port mode. For more information, see the Fibre Channel Configuration sections in ”N1200-320 4Gb Network Storage Router

management” on page 27 and ”Fibre Channel port configuration” on page 42.

FC arbitrated loop addressing

On a Fibre Channel Arbitrated Loop, each device appears as an Arbitrated Loop Physical Address (AL_PA). To obtain an AL_PA, two addressing methods, called soft and hard addressing, can be used by the network storage router. Soft addressing is the default setting. For hard addressing, the user specifies the AL_PA of the network storage router.

Soft addressing

When acquiring a soft address, the network storage router acquires the first available loop address, starting from address 01 and moving up the list of available AL_PAs in the chart from 01 to EF. In this mode, the network storage router obtains an available address automatically and then participates on the FC loop, as long as there is at least one address available on the loop connected to the network storage router. Fibre Channel supports up to 126 devices on an Arbitrated Loop.

Hard addressing

When acquiring a hard address, the network storage router attempts to acquire the AL_PA value specified by the user in the configuration settings. If the desired address is not available at loop initialization time, the network storage router comes up on the FC loop using an available soft address. This allows both the loop and the unit to continue to operate. An example of this scenario would be when another device on the Arbitrated Loop has acquired the same address as that configured on the network storage router.

Hard addressing is recommended for FC Arbitrated Loop environments where it is important that the FC 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 of this would be a tape library installation, where the application configuration requires fixed device identification for proper operation. Hard addressing ensures that the device identification to the application remains constant.

FC switched fabric addressing

When connected to a Fibre Channel switch, the network storage router is identified to the switch as a unique device by the factory programmed World Wide Name (WWN) and the World Wide Port Names (WWPN), which are derived from the WWN.

N1200-320 4Gb Network Storage Router user and service guide 23

Discovery

Discovery is a feature that makes it easy to display attached FC and SCSI target devices and have them mapped automatically on the host side for the connected bus/port.

There are two discovery methods available—Manual Discovery and Auto Discovery. Auto Discovery can be set to occur after either reboot events (when the card reboots) or link-up events (for instance, when cables are attached or a hub is rebooted). Discovery can also be turned off by setting the network storage router to Manual Discovery Only. The default setting for FC Discovery is Manual Discovery.

For specific information on Discovery settings, see the Fibre Channel configuration and SCSI configuration sections in ”N1200-320 4Gb Network Storage Router management” on page 27 and ”Discovery menu” on page 45.

Host bus adapter configuration

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

Mapping usually involves pairing FC AL_PAs to SCSI target addresses. The HBA claims enough SCSI bus entries to allow for 125 FC targets to map to SCSI bus:Target entries. This is usually done by a fixed mapping of AL_PA to Bus:Target. In such a configuration, the network storage router corresponds to a Bus:Target identifier, with the SCSI devices attached to the network storage router 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 are valid SCSI IDs, and not correctly handle certain mappings. In particular, applications have been seen to exhibit difficulties addressing target IDs greater than 15 (e.g. 16 and up). This problem can be resolved by configuring the network storage router to use hard addressing, and setting the AL_PA used by the unit to a value that the HBA will map to an ID with a value less than 16.

For example, depending on the FC HBA, if the hard AL_PA selection is 1, the network storage router address is 1. If the selection is 125, the network storage router address is 0xEF. Some FC HBAs configure differently, so verify the AL_PA by reviewing the documentation for the HBA.

Logical unit management

Because SAN resources can be shared, multiple hosts can have access to the same devices on the SAN. To prevent conflicts, the network storage router provides the means to restrict access and only allow hosts to find and access selected devices. Simple LUN masking can restrict access, but many times this leaves gaps in the list of LUNs presented to a host, since devices are always associated with fixed LUNs. The network storage router, however, provides controlled access to devices by use of LUN management, which goes beyond simple LUN masking.

LUN Management is the ability to present different hosts with different views of the devices accessed through the network storage router. For example, one FC host may see three disk LUNs and a tape LUN at LUNs 0 to 3 when it performs discovery on the network storage router. Another FC host may only discover a tape LUN at LUN 0. Not only can the administrator control which devices a host may access, but also which LUNs are used to access these devices.

LUN Management is accomplished by allowing the administrator to configure multiple maps, each of which may present a different view of the devices behind the network storage router. Each host accessing the network storage router can be associated with a specific map.

For a host connected to an FC port, a map is a table of LUNs where each entry in the table is either empty or contains device address information needed to route commands to the appropriate device.

The FC port on the network storage router has a set of maps which include user defined maps and a few special predefined maps.

There are currently four special predefined maps: Indexed, Auto Assigned, SCC, and Port 0 device maps. Until a user configures the network storage router otherwise, the default map setting is Indexed.

24 Device management

• The Indexed map is initially empty and can be modified by the user, however, this is not

recommended.

• The Auto Assigned map is built dynamically, and contains all the devices found during discovery. This

map changes automatically any time the discovery process finds a change in the devices attached to the network storage router. This map can be displayed, but cannot be modified directly by the user.

• The SCC map is only available on the FC port and contains a single entry. LUN 0 is an network

storage router LUN, and access to devices behind the controller is handled by using SCC logical unit addressing.

When a host sends a command to the network storage router, the network storage router selects which map to use, based on the ID of the host sending the command. For FC 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 to the network storage router, or is not attached to a specific map, the network storage router uses the default setting for mapping. The default setting for each port can be set to Auto-assigned, Indexed, or SCC (which applies to the FC port only) by the user.

4 N1200-320 4Gb Network Storage Router

management

The HP N1200-320 4Gb Network Storage Router can be managed over the following user interfaces:

• Over the serial port via a terminal or a terminal emulation utility (see ”Setting up serial port

communications” on page 18).

• Over Ethernet via a Telnet utility or an HTTP-based interface called Visual Manager. Additionally, FTP

support provides additional management functionality (see ”Visual manager user interface” on page 31).

Before attempting to configure the network storage router, a basic understanding of Fibre Channel and SCSI devices is recommended.

NOTE: 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, you can contact ANSI at (212) 642-4900.

Configuration methods

The network storage router can be configured over the serial port via a terminal or terminal emulation utility, over Ethernet via a Telnet utility or Web browser. FTP is also supported on Ethernet.

Serial port management access

The serial port allows for configuration of device characteristics from an attached terminal or terminal emulator (see ”Setting up serial port communications” on page 18).

NOTE: A Serial connection cannot be made if a Telnet session (discussed later) is already open. If a user

attempts to open a serial connection while a Telnet session is already open, the following message appears over the serial interface:

System in use via Telnet. Shell restarted.

The serial interface resumes working when the Telnet session closes.

Out-of-band Ethernet management access

DHCP is enabled by default. The first time you use the network storage router, use the serial interface to identify the network settings that were assigned from the DHCP server, or to set a new static setting.

When DHCP is disabled, the pre-filled in values are IP address 1.1.1.1, a subnet mask of 255.255.255.0, and a gateway address of 0.0.0.0. HP recommends that at a minimum, the IP address should be changed.

CAUTION: HP strongly recommends not having two network storage routers using the pre-filled in static IP

address on the same network, as this causes a conflict.

When setting the IP address for the network storage router, there are two options:

• The first option is to enter a fixed, or permanent IP address for the network storage router.

• The second option is to enable DHCP on the network storage router, so that a DHCP server (on the

Ethernet network used by the network storage router) can assign a dynamic IP address to the network storage router.

N1200-320 4Gb Network Storage Router user and service guide 27

Your DHCP server may also allow you to set up an extended lease reservation for an IP address, by providing the server with the Ethernet MAC address of the network storage router. This configures the DHCP server to always provide the same IP address to the network storage router. This setup can be useful for remote management of the network storage router via Telnet. Because the method of setting up a lease reservation varies depending on the DHCP server being used, HP recommends that you contact your Network Administrator for assistance.

For more information about enabling DHCP on the network storage router, see ”Enabling DHCP on the HP

N1200-320 4Gb Network Storage Router” on page 117.

Command Line Interface

The network storage router is capable of holding Telnet sessions for configuration purposes. Access to the configuration menus via the serial port will be disabled when a Telnet session is connected. To open a Telnet session, the IP address of the network storage router and a Telnet client utility are required.

NOTE: Rebooting the network storage router closes the Telnet session. After the network storage router

reboots and completes POST, the user must restart or re-open the Telnet session.

NOTE: Resetting to factory defaults from the Telnet interface does not affect Ethernet activity. User

configured values for the IP address, gateway, and subnet mask are retained after the network storage router reboots. User name and password are not retained.

NOTE: The network storage router supports only one Telnet session at a time.

From most Windows systems, users can start a Telnet session from the DOS (or Command) prompt using the following steps:

1. From the Windows Start menu, open the DOS (or Command) prompt window.

2. At the ‘>’ prompt, enter the following command

TELNET <IP address> where <IP address> is the IP address of the network storage router. This starts a Telnet session

window for the network storage router.

3. Enter root for the default user name and password for the default password. HP recommends that

you change the user name and password as soon as possible.

4. Access configuration options in the same way used for the serial interface.

5. To exit the Telnet session, select the Disconnect option from your Telnet client utility. In most Telnet

utilities, this option is available as a menu item. If working from the Command Prompt in Windows, simply close the window to end the session.

28 N1200-320 4Gb Network Storage Router management

Visual manager

The network storage router allows any standard Internet Web browser to view and change the network storage router’s configuration with the Visual Manager interface. Information is dynamically generated in an HTML format by the network storage router, so that Web browsers can access it.

To access Visual Manager, enter the IP address of the network storage router into the Address field of a Web browser. Or, you can enter a URL using a host name defined by the user—for instance, http://HPN1200-3204Gb (but the user must define the host name on the DNS server first for this to work).

To make changes to network storage router settings, use standard keyboard and mouse controls to input information, and then select the Submit button to send the changes to the network storage router.

A user name and password are required before any changes can be submitted. The default user name is root and the default password is password. HP recommends that you change the user name and password as soon as possible (see ”User name and password” on page 38).

Other than dynamic mapping changes, any other changes will not take effect until the next time the network storage router reboots. You can force the network storage router to reboot by selecting the Reboot option.

For more information about the Visual Manager interface, refer to ”Visual manager access” on page 31.

NOTE: For the VM interface’s dynamic display of the network storage router configuration to be

presented properly, use version 6.2 or later of Netscape’s browser on non-Solaris platforms, or Netscape version 6.2.3 for Solaris platforms. If using Internet Explorer, use revision 6.0 or later.

FTP

The network storage router includes support of File Transfer Protocol (FTP) for updating firmware, saving trace buffers, and backing up/restoring of configuration settings. FTP functionality is described in more detail in ”Using the Command Line Interface” on page 59. There is also an FTP Utility available within Visual Manager (VM) that is described in ”FTP utility access” on page 51.

Inband SCSI-3 commands

The network storage router supports a set of SCSI-3 commands that can be received as FCP commands over the Fibre Channel ports. When using these commands, they must be sent to a tape LUN or network storage router LUN of the network storage router. For more information, see ”Inband SCSI-3 commands” on page 109 and ”HP N1200-320 4Gb Network Storage Router features” on page 11.
