Introduction 1 The HP StorageWorks Network Storage Router M2402 provides bi-directional connectivity for up to 12 Narrow/Wide Fast/Ultra-2 SCSI buses in either a Fibre Channel Switched Fabric (FC-SW) or a Fibre Channel Arbitrated Loop (FC-AL) environment.
Introduction External Features Overview Figure 1 and Figure 2 show front and back views of the router. Figure 1: Front view The air intake vents on the front left side, shown in Figure 1, must remain unobstructed. The power supply modules (with fault and power LED) are serviceable from the front of the router. The serial port is also located on the front for local management of configuration settings and firmware upgrades.
Introduction Power Module The router is equipped with one power supply and has the capability of a redundant power supply being added. Figure 3: Power module Power supply LED definition: Green - Power has been applied to this module Yellow - Power-On Self-Test (POST) in process or processor problems Fan Module The router is equipped with three fans in a single module.
Introduction If one of the three fans fails, the router will continue to operate on the two remaining fans until a replacement fan module can be installed. If the fan is not cooling the router properly, a temperature warning message is displayed in the Home Page of the Web-based user interface. Fan module functionality can be verified from both the Serial/Telnet user interface and the Web-based user interface. Note: The Web-based user interface is also called Visual Manager.
Introduction SCSI Modules Multiple SCSI modules can be added to the router. Figure 6: SCSI module SCSI module LED definition: Green - SCSI bus activity on corresponding port Ethernet Port/Standby Power Button The router is equipped with one Ethernet port and a standby power button with LED indicators ( see Figure 7).

This button does not remove power to the power module(s). To remove power to the power module(s), unplug the router from electrical source.
Introduction Functional Overview The router translates the Fibre Channel Protocol (FCP) to and from the SCSI Protocol. It transfers commands, data, and status information to and from Fibre Channel (FC) controllers and SCSI devices.
Introduction Fibre Channel to SCSI Protocol Process This section describes the steps the router uses to convert FC host protocol to SCSI device protocol. Figure 10 and the supporting table illustrate and define this process.
Introduction SCSI to Fibre Channel Protocol Process In this example, a SCSI host (initiator) on the SCSI bus issues commands and the information is passed through the router to a target on the Fibre Channel Storage Area Network (FC-SAN). Figure 11 is an illustration of the process and the supporting table defines each step.
Introduction LAN-free Backup and Restore The router can enable LAN-free backup/restore to allow the bulk of data traffic to be moved from the LAN to the storage area network (SAN) (see Figure 12).
Introduction Server-free Data Movement Used with server-free application software, Copy Manager allows the server to off load data movement to the router and free up server resources (see Figure 13). Fibre Channel ETHERNET SCSI COMMAND SCSI TAPE UNIT DATA MOVEMENT SCSI TAPE UNIT StorageWorks Router FIBRE CHANNEL DISK StorageWorks Router SAN SERVER SERVER SERVER SERVER LAN Figure 13: Server-free data movement Note: Copy Manager can perform simultaneous Extended Copy commands.

Installation For convenience in configuring ports, important information can be found on a label located on the underside of the router (see Figure 21). WWNN: 100000E00200N000 WWPN: 100000E00Y00N000 ENET MAC ID: 00:E0:02:00:00:XY Figure 21: WWN/MAC ID label Fibre Channel Connections In typical installations, the router may be connected to: ■ Arbitrated Loop (AL) – the router can be directly attached to the FC host adapter in a point-to-point configuration.
Installation Fibre Channel Hub Max 10 Km Distance Host Max 10 Km Distance StorageWorks Router FC HBA SCSI Tape Library Tape Library Tape Library Tape Library Fibre Channel SCSI Figure 22: Configuration with tape library using Arbitrated (or Private) loop Both FC switches and hubs may allow individual ports to be configured for different media types. The router must be connected to the hub or switch port with the appropriate FC cabling for the media type in use.
Installation To connect the router to a FC storage area network (SAN): 1. Locate the FC ports on the back of the router (see Figure 23). Figure 23: Fibre Channel ports 2. Remove the rubber protective inserts from the Small Form Factor Pluggables (SFP). 3. With the router powered off, connect the router to the FC environment, using the appropriate cabling. The FC optical connectors on the router are keyed for proper orientation. Caution: The router has been qualified with a specific set of SFPs.
Installation SCSI Connections The router supports Fast/Ultra-2 Narrow/Wide SCSI. The router is factory configured to support LVD/Single-Ended or HVD (Diff), or a mixture of both types of SCSI buses. Up to twelve SCSI buses can be attached, using 3 SCSI modules. Note: The router must always be installed at the end of SCSI buses. The router supplies termination power (TERMPWR) to each SCSI bus. Note: During certain faults, the termination power IC will shut down.
Installation Note: SCSI cables used with the router must meet SCSI 2 standards. Optional SCSI cables are available from your supplier. To connect the router to a SCSI device: 1. Power off the router and SCSI devices. 2. Locate the SCSI buses on the back of the router (see Figure 24). Figure 24: SCSI buses 3. Connect a SCSI cable to one of the SCSI buses on the router. Note: The router should always be installed at the end of the SCSI bus. Note: SE is not supported by SCSI-3 protocols.
Installation 6. Power on all attached SCSI devices. 7. After all the SCSI devices have completed their individual POST (Power-On Self-Test) processes, power on the router. Ethernet Connections 10/100BaseT Ethernet connectivity provides enhanced management and configuration capabilities. The RJ-45 connector on the router can be directly connected to a standard 10/100BaseT Ethernet network. To allow configuration capabilities via this port, the IP network address must be set.
Installation Serial Port Connections The DB-9 connector provides a serial port that is compliant with the EIA 562 standard and is RS-232 signaling-level compatible. The serial connection can be used to configure the unit, to monitor its diagnostic status, or to update the router firmware. Figure 26 is an illustration of the serial port location on the front of the router.
Installation Setting up Serial Port Communications To set up serial port communications: 1. Connect the serial cable between the host computer serial port (COM1 or COM2) and the router serial port. 2. Power on the router. 3. Power on the server. 4. Start the host terminal or terminal interface program (Microsoft Windows 9x, Windows NT 4.0, or Windows 2000 HyperTerminal). 5. Set the terminal or terminal interface program to use the appropriate COM port. 6. Configure the selected COM port. 7.
Configuration Overview 3 The HP StorageWorks Network Storage Router M2402 can be configured and managed using several user interfaces (UI). Each UI is introduced in this chapter, along with information about common configuration settings.
Configuration Overview Router Default 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 these values be changed from the defaults. All settings within the router configuration are pre-set with default values. These values are set to allow the router to be installed into most HP environments with little or no configuration changes.
Configuration Overview UI Overview The router supports the following user interfaces: ■ Visual Manager ■ Serial/Telnet ■ FTP Each UI is introduced in the following paragraphs. Visual Manager Visual Manager allows any standard web browser to view and change router configuration. Information is dynamically generated in an HTML format so that any web browser can access it.
Configuration Overview Common Configuration Settings To provide connectivity between hosts and devices, the router must establish an address on each connected FC 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 4, “Visual Manager User Interface,” and Chapter 5, “Serial/Telnet User Interface.
Configuration Overview Fibre Channel Port Configuration By default, the configuration of the FC ports is set to N_Port, which minimizes conflicts when both the router and another FC device, such as a switch, are using Auto Sensing for FC ports. Alternatively, the configuration of the FC ports can be set to Auto Sensing, which allows the router to detect whether it is connected to an Arbitrated Loop or a Switched Fabric. Note: By default, the Fibre Channel port speed is set to 1 Gb/s.
Configuration Overview 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 is tape library installation, where the application configuration requires fixed device identification for proper operation.
Configuration Overview (16 and up, for example). 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 FC 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 FC HBAs will map devices differently, so verify the AL_PA by reviewing the documentation for the HBA.
Configuration Overview Indexed Maps An Indexed map is initially empty and can be modified by the user. 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 FC ports and contains only a single entry for LUN 0. This LUN is a router controller LUN.
Visual Manager User Interface 4 The HP StorageWorks Visual Manager user interface (UI) provides a graphical and intuitive format that is used to remotely view and change router configurations. Use the Microsoft Internet Explorer or Netscape (version 6.2 or greater) Web browsers to access Visual Manager. Information is presented in HTML format in accordance with the W3C specification for HTML 3.2. Current W3C recommendations and other technical documents can be found at http://www.w3.org/TR/.

Visual Manager User Interface Power Supply Configuration The Power Supply screen is used to indicate the number of power supplies installed in the router. The router is shipped with one installed power supply, but a redundant power supply can be purchased. If two power supplies are installed in the router, use this screen to indicate the change (see Figure 38). When set to 1, the router suppresses event notifications of the second power supply.
Visual Manager User Interface Reset Menu The Reset Menu is used to reset the router to factory default settings (see Figure 39). Figure 39: Reset to Factory Default screen Current router activities will be disrupted while the unit resets the configuration to the factory defaults and saves those options to FLASH memory. Note: Resetting to factory defaults through VM will not affect Ethernet connectivity. User-configured values for the IP address and gateway will be retained.
Visual Manager User Interface Modules Menu Accessed from the Main Menu, the Modules Menu is used to view and modify configuration settings of FC and SCSI modules. The initial screen display of the Modules Menu includes summary information about each FC and SCSI module in the router (see Figure 40).
Visual Manager User Interface Modules Menu tasks: ■ World Wide Node Name configuration changes World Wide Node Name. ■ Fibre Channel Module configuration changes FC module settings. ■ SCSI Module configuration changes SCSI module settings. Each Modules Menu option is discussed in the following sub-sections. World Wide Node Name Configuration The World Wide Node (WWN) Name screen is used to change the WWN Name settings for the router. Figure 41 is an example of the World Wide Node Name screen.
Visual Manager User Interface Fibre Channel Module Configuration When a Fibre Channel (FC) module is selected in the Modules Menu, the FC Module Port Configuration Settings screen for port 0 is displayed. The FC Module Port Configuration Settings screen is used to view and modify FC module configuration settings. Because port 0 is automatically displayed, to change settings for a different FC port, select the desired port on the FC module on the menu bar or on the router image (see Figure 42).
Visual Manager User Interface Fibre Channel module port settings: ■ Link Status indicates the port link status. ■ Port Mode (default: N_Port) sets the port mode. Port Mode settings: — Auto Sense In this mode, the FC port tries to negotiate as a loop. If it is not successful, then the FC 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.
Visual Manager User Interface ■ Discovery Mode (default: auto discovery on reboot events) determines how the router will discover new FC devices. Discovery Mode settings: — Auto Discovery on Reboot Events (default) allows the router to automatically discover all FC 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.
Visual Manager User Interface ■ Default Map (default: indexed) sets the current mapping mode for the selected port. The current map can be set to: — Indexed (default) — 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” on page 93. ■ Performance Mode (default: 1 Gb/s) toggles between 1 Gb/s and 2 Gb/s.
Visual Manager User Interface Override Settings dialog box settings: ■ Port Name High sets a new value for the World Wide Port Name High. 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. ■ Port Name Low sets a new value for the World Wide Port Name Low.

Basic Troubleshooting 8 This chapter discusses some basic methods of identifying faults in the setup and configuration of the HP StorageWorks Network Storage Router M2402. Before proceeding with advanced troubleshooting techniques, verify that all connections are correct and review the configuration.
Basic Troubleshooting LED Indicators The LED indicators on the router are useful for diagnosing various problems: ■ The Power LED indicates when power is applied to the router. If the power LED is not lit, verify the power supply source or check for an internal problem with the power module. ■ The Fault LED indicates that the router detects a fault condition on the power module. If the fault indicator stays lit, contact Systems Support.
Basic Troubleshooting Basic Troubleshooting If possible, simplify the installation by reducing it to the most basic configuration. Then, add elements one at a time, verifying the operation after each step.
Basic Troubleshooting Verifying SCSI Bus Configuration Items to check include: ■ Termination—Problems with termination can cause intermittent or hard failures. A SCSI bus must be terminated on both ends. Termination problems are common when both narrow and wide devices are on the same bus. ■ Bus Type—On an LVD SCSI module, SE and LVD devices can be connected to the same bus. However, if one SE device is detected during power up, communication to all devices will convert to SE mode.
Basic Troubleshooting One method of verifying link integrity when connected to a functional host, involves disconnecting and then reconnecting the FC cable. This procedure should cause momentary activity of this indicator as the link reinitializes. Additionally, verify that the media type of the router and the attached hub, HBA, or switch is of corresponding types. When using optical media, verify that the attached device is using non-OFC type optical devices.
Basic Troubleshooting Verifying Mapping If the router is working in FC-to-SCSI Initiator mode and is using Indexed or SCC mapping, try changing to Auto-assigned mapping. Verifying Devices It may be useful to connect the SCSI target devices directly to a SCSI interface (for example, a host SCSI bus) to verify that the devices are functional. Verifying the Host Configuration In some cases, it may be that the FC HBA or host device driver may not be working properly.
Basic Troubleshooting Verifying Serial Port Configuration Verify the configuration of the terminal or terminal emulation program. Table 5: Terminal Emulation Configuration Settings Item Setting BAUD Rate Autobaud, 9600, 19200, 38400, 57600, 115200 Data Bits 8 Stop Bit 1 Parity None Flow Control XON/XOFF If problems persist, verify the cabling. If a valid Ethernet IP address is configured, serial configuration settings can also be set via Telnet.

Controller LUN Commands B The HP StorageWorks Network Storage Router M2402 supports and executes the set of SCSI-3 commands listed in this Appendix. These commands can be received as FCP commands over the FC bus and are supported by the Controller LUNs. This document refers to these commands as Controller LUN commands. Complete definitions of SCSI-3 commands can be found in the SCSI-3 standard available from the American National Standards Institute (ANSI).
Controller LUN Commands General Commands ■ Report LUNs ■ Inquiry Each of these commands is discussed in the following paragraphs. Report LUNs Command The Report LUNs command returns a list of LUNs that can receive commands. The format of the Report LUNs command is shown in Table 7.
Controller LUN Commands The router returns the LUN Parameters as defined in Table 8. Table 8: Report LUNs Data Bit/Byte 7 6 5 4 3 2 0 Most Significant Byte (MSB) 1 LUNS Length List 1 0 2 3 Least Significant Byte (LSB) 4 Reserved 5 Reserved 6 Reserved 7 Reserved All LUNs are reported and will appear in the host map. Note: In addition to the device LUNs, controller LUNs are also included in the report. Controller LUN values are displayed at the end of the list.
Controller LUN Commands EVPD Page 0x80 If the EVPD bit (bit 0 of byte 1) is set and the Page Code is 0x80, the unit serial number page is returned. The format of this page is shown in Table 10. Table 10: Format of EVPD Page 0X80 Bit/Byte 0 7 6 5 4 3 2 1 0 Device Type (Example: 0x0c) 1 Page Code (80h) 3 Reserved 4 Page Length 5 Serial Number The router returns the LUN Inquiry Data as defined in Table 11.
Controller LUN Commands Table 11: LUN Inquiry Data Item Value Vendor ID “HP” Product ID “router” Revision Level “XXXXXX” The router will only reply to a SCSI Inquiry using 8-byte LUN field of 0x00. Note: The Revision Level comes from the last four characters of the build string, which appears in the headings for most menu screens.
Controller LUN Commands Copy Manager Commands To access Copy Manager or other general management features, the commands must be sent to the router controller LUNs. The following controller LUN commands can be used for Copy Manager on the router: ■ Extended Copy ■ Receive Copy Results ■ Mode Sense (6) and Mode Sense (10) Each of these commands is discussed in the following paragraphs.

C Addressing Methods and Table Structures Fibre Channel (FC) and SCSI systems use different methods of addressing devices. The router has a method of translating device IDs so each SCSI device is mapped to the appropriate Fibre Channel LUN. The SCSI buses establish the bus connections between devices. Targets on a SCSI bus may internally address LUNs. The addressing of a specific SCSI device is represented by the BUS:TARGET:LUN triplet.
Addressing Methods and Table Structures Table 20: SCSI Logical Unit Addressing Bit/Byte 7 6 5 N 1 0 Target 4 3 2 1 0 4 3 2 1 0 Table 21: Peripheral Device Addressing Bit/Byte 7 6 5 N 0 0 Bus N+1 Target/LUN Depending on the configuration, the router supports the Peripheral Device Addressing method and the Logical Unit Addressing method. The data shown in Table 22 comes from the FC Configuration Menu.

Addressing Methods and Table Structures SCC (SCSI Controller Command) Addressing Method When a router is configured to use SCSI Controller Command addressing (SCC) and a command is received, the router either will respond as a controller device to the FCP Initiator or will route the FCP request to a specified BUS:TARGET:LUN.
Addressing Methods and Table Structures Auto Assigned Addressing Method The Auto Assigned addressing method is created through SCSI device discovery on power up or reset. As the router performs device discovery on the SCSI bus, the index table FCP LUN values are filled with adjacent FCP LUN referencing each subsequent SCSI device. The index table generated by the Auto Assigned option cannot be manually edited.
Addressing Methods and Table Structures Indexed Addressing Method Indexed addressing allows for host bus adapter (HBA) drivers that use only Peripheral Device Addressing to access SCSI devices attached to the router. This addressing is done by use of a table, which is indexed by sequential LUN values, indicating the selected BUS:TARGET:LUN devices. In this mode, it is not possible to address the router as a controller unit directly.
