1 Introduction The HP StorageWorks N1200-320 4Gb Network Storage Router provides bi-directional connectivity between one Fibre Channel Switched Fabric (FC-SW) or Fibre Channel Arbitrated Loop (FC-AL), and two Narrow/Wide Fast/Ultra320 LVD/SE SCSI buses. Supported devices include: • Initiator Devices – Fibre Channel hosts • Target Devices – Tape drives External features overview The front of the HP N1200-320 4Gb Network Storage Router is shown in Figure 1.
Operation indicators The HP N1200-320 4Gb Network Storage Router has LED indicators for monitoring overall status as shown in Figure 3.
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.
External indicators • Fibre Channel link status and activity LEDs • SCSI bus activity LED • Ethernet link status and activity LEDs • Power/Fault LED HP N1200-320 4Gb Network Storage Router benefits The network storage router is designed to connect SCSI devices into a Fibre Channel (FC) fabric or loop. The network storage router comes with one 4 Gb/s Fibre Channel port and two LVD/SE SCSI buses.
2 Installation, cabling, and setup NOTE: Read this chapter carefully and completely before working with the network storage router.
Desktop installation Remove the router from the protective bag. Attach the stick-on feet to the bottom four corners of the router. Place the router on a flat, level table or desktop making sure the airflow vents are clear of obstructions. WARNING! Do not place objects on top of the network storage router. Rack mount installation IMPORTANT: The size of the router and it’s rail assembly is 1U.
Attach the outer rail assembly to the rack NOTE: The size of the router and the rail assembly is 1U. 1. Determine the correct rack location. 2. Align the three screw holes on the front of the outer rail assembly with the front of the rack. All three holes must be exactly aligned. 3. With the outer rail assembly flush against the inside front of the rack, insert two 10-32 x 6 Phillips screws, and tighten. Do not insert a screw in the center hole of the bracket.
Attach the rear extension bracket 1. Loosen the screw on the rear extension bracket of the outer rail assembly. 2. While holding the outer rail assembly level, extend the rear extension bracket to the inside of the rear of the rack. 3. Attach the rear extension bracket to the rear of the rack using two of the 10-32 x 6 Phillips screws. 4. With the outer rail assembly in place, tighten the screw that connects the rear extension bracket to the outer rail. 5.
Install the router into the rack 1. Move the ball-bearing slide on each of the outer rails towards the front of the rack. 2. From the front of the rack, with the front side of the router facing out, align the inner and the outer rails and slide the inner rail into the outer rail. 3. When the rails lock in place, press in the spring latches on each of the inner rails and push the router into the rack.
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.
Cabling the N1200-320 4Gb Network Storage Router 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.
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.
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.
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.
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).
• 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.
Device management
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).
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.
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.
N1200-320 4Gb Network Storage Router management
5 Visual manager user interface The HP N1200-320 4Gb 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.
5. Enter the authorized user name and password. The user name and password are case-sensitive. The default user name is root and the default password is password. Figure 10 Password dialog box NOTE: HP recommends changing the user name and password from the defaults (see”User name and password” on page 38). 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.
Home page The Main menu home page is displayed when Visual Manager (VM) is accessed. The home page contains status information, including a physical image of the network storage router (see Figure 12). Figure 12 Visual Manager Home page Home page information includes: • The HP logo is located in the upper left corner of the Home page. If the Internet is accessible to the host, click the HP logo to open the web site. • An illustration of the network storage router is located near the top of the home page.
• Main menu options: • Home displays network storage router status information. • System configures standard system components. • Ports configures the Fibre Channel port and SCSI buses. • Discovery displays devices and discovers new devices. • Mapping displays and configures maps. • Statistics displays network storage router statistics. • Utilities configures utility settings. • Report displays system information. • Reboot restarts the network storage router.
Serial configuration The Serial screen is used to change the baud rate for the serial port (see Figure 15). NOTE: If the Autobaud feature is being used, it may not be necessary to set the baud rate. Figure 15 Serial screen The current baud-rate setting is displayed. Baud rate choices are: • 9600 • 19200 • 38400 • 57600 • 115200 NOTE: HP recommends setting the baud rate to 115200.
Network configuration The Network screen is used to enter Ethernet configuration settings (see Figure 16). Figure 16 Network screen 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 network storage router configuration to an external file before making changes to this setting.
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 a DHCP server, the standard for DHCP requires the network storage router to wait three minutes for a response from a DHCP server before timing out. Some DHCP servers allow an extended 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 network storage router.
User security settings User name and password The User screen is used to set up network storage router security such as the user name and password (see Figure 18). Figure 18 User screen User settings: • User Name (default: root) is any alphanumeric combination. • Password (default: password) is any alphanumeric combination. Passwords must be 8 to 11 characters in length. • Confirm Password The user name and password should be unique and kept confidential.

8 Troubleshooting Various problems can arise when configuring and using the HP N1200-320 4Gb Network Storage Router. This section is provided to help guide the user through some of the basic methods of identifying faults in the setup and configuration of the network storage router. Most problems are found in the initial installation. In general, it is wise to check all connections and review the configuration before proceeding with further trouble analysis.
corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify the SCSI bus configuration. • Ethernet (10/100)—The LNK should stay permanently lit to indicate an Ethernet link. The ACT indicator should flash to indicate activity. If either of these indicators fail to flicker, or stay continuously lit, there may be a problem with the network connection or configuration. Verify the network connection and configuration.
discovered” device every time there is a reboot. By using the included INF file, the user just needs to identify the network storage router to the Windows Device Manager only once. To install (or register) the network storage router to a connected host Windows PC, perform the following steps: 1. Copy the INF file to the Windows PC which has the FC HBA to be connected to the network storage router.
Even if the SCSI devices are displayed, they are not accessible unless the mapping mode is auto-assigned or another non-empty map is used. Verify Fibre Channel connection If SCSI devices are recognized on the SCSI buses, but do not appear to the Fibre Channel host, it may be that the Fibre Channel link is not properly established. Most hubs and switches have link indicators, showing link status.

C Inband SCSI-3 commands The HP N1200-320 4Gb Network Storage Router supports a set of SCSI-3 commands that can be received inband over FCP. When received by the network storage router, these commands are then executed by the network storage router itself. When using SCSI-3 commands to access general management features, the commands can be sent to device LUNs that are mapped through the network storage router. The following is a list of the SCSI-3 commands that are supported by the network storage router.
The network storage router returns the LUN Parameters as defined in Table 12. Table 12 Report LUNs Parameter List Bit 7 6 5 4 3 2 1 0 Byte 0 (MSB) 1 LUN list length 2 3 (LSB) 4 Reserved 5 Reserved 6 Reserved 7 Reserved LUN list 0-7 First LUN : 0-7 Last LUN NOTE: The LUN list length is the number of LUNs times 8. All LUNs are reported and will appear in the host’s map. Inquiry command The format of the Inquiry command is shown in Table 13.
EVPD Page 0x80 If the EVPD bit is set and the Page Code is 0x80 the unit serial number page is returned. The format of this page is shown in Table 14. Table 14 Format of EVPD Page 0x80 Bit 7 6 5 4 3 2 1 0 Byte 0 Device Type (0ch) 1 Page Code (80h) 3 Reserved 4 Page Length 5...20 Serial Number The serial number field is a 16-byte left-justified ASCII string.
NOTE: The Revision Level comes from the last four characters of the build string, which appears in the headings for most menu screens.
D Addressing, structures, and operations Fibre Channel and SCSI systems employ different methods of addressing devices. The inclusion of a network storage router requires that a method of translating device IDs be implemented so that each SCSI device is mapped to the appropriate Fibre Channel LUN. The SCSI buses establish bus connections between devices. Targets on a SCSI bus may internally address logical units. The addressing of a specific SCSI device is represented by the BUS:TARGET:LUN triplet.
The network storage router supports the Peripheral Device Addressing Method and the Logical Unit Addressing Method, depending on the configuration.
Indexed addressing option Indexed Addressing allows for host bus adapter (HBA) drivers that only use Peripheral Device addressing to access SCSI devices attached to the network storage router. This is done by use of a table, which is indexed by sequential LUN values, indicating selected BUS:TARGET:LUN devices. It is not possible in this mode to address the network storage router as an network storage router unit directly. The table has the structure as shown in Table 21.
attached devices directly without having to perform discovery by issuing commands through all possible combinations.
E Enabling DHCP on the HP N1200-320 4Gb Network Storage Router DHCP, or Dynamic Host Configuration Protocol, is an open industry standard that simplifies administering networks based on Transmission Control Protocol/Internet Protocol (TCP/IP). DHCP allows network resources to go farther by enabling a unique IP address to be assigned to a specific device (network storage router, client host, etc.) on a non-permanent, dynamic basis.
Setting up DHCP over network storage router interfaces Network storage routers use three different interfaces which can be used to enable DHCP: Serial, Telnet, and VM. The following will describe how to enable and disable DHCP for each interface. NOTE: Located on the network storage router is a label that displays the unit’s Ethernet MAC Address. A network administrator can then use this MAC Address to set up a lease reservation on the DHCP server for the IP address of the network storage router.
• Select 2. The following menu appears: Figure 79 Ethernet configuration menu Ethernet Configuration Menu X.X.XX XXXXXX XXXXXX-XXX_XXXXXXXXXXXXXX 07/7/2005 08:56:22 IP Address : 1.1.1.1 Subnet Mask : 255.255.255.0 IP Gateway : 0.0.0.
DHCP has been successfully activated. Note that the IP Address my also appear different than the former non-DHCP IP Address. NOTE: To use the DHCP feature, a DHCP server must be operational on the Ethernet network used by the network storage router. If the DHCP feature is used when there is no DHCP server, the standard for DHCP requires that the network storage router wait three minutes for a response from a DHCP server before timing out.
Visual Manager To access the network storage router using the Visual Manager interface: 1. Look up the current IP address within the Ethernet Configuration menu using the serial interface. 2. Type the IP address in the Web browser without using “www” or “/” or any other characters or symbols. 3. After entering the IP address, the user should see the Configuration Main menu. Click on the Configuration link. This will access the Configuration Menu containing CURRENT/NEW readings for DHCP (“Use DHCP”).
