Introduction 1 The HP StorageWorks Network Storage Router provides bidirectional connectivity for Narrow/Wide Fast/Ultra-3 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 illustrate the panel view of the router.
Introduction Power Indicator The router has one power LED. Power indicator LED definition: Green - Power has been applied to this module Yellow - Power-On-Self-Test (POST) in process or processor problems Serial Port The router is equipped with one serial port. See Figure 2 on page 18 for the location of the serial port. The serial port can be used to access the Serial/Telnet user interface, which is used to locally manage and configure the router.
Introduction Fibre Channel Port One Fibre Channel port with LED indicators is included in the router. See Figure 2 on page 18 for the location of the Fibre Channel port. Fibre Channel LED definition: Green (ACT) - Fibre Channel port activity Green (LINK) - Valid Fibre Channel link SCSI Buses Two SCSI buses with LED indicators are included in the router. See Figure 2 on page 18 for the location of the SCSI buses.
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 controllers and SCSI devices.
Introduction Fibre Channel to SCSI Protocol Process This section describes the steps the router uses to convert Fibre Channel host protocol to SCSI device protocol (see Figure 4).
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 5 is an illustration of the process and 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 6). Figure 6: LAN-free backup and restore Fibre Channel ETHERNET SCSI TAPE UNIT SCSI DATA MOVEMENT SCSI TAPE UNIT StorageWorks Router Link/ Act Pwr. Link/ Act Fibre Channel Pwr.
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 7). Figure 7: Server-free data movement Fibre Channel ETHERNET SCSI COMMAND SCSI TAPE UNIT DATA MOVEMENT SCSI TAPE UNIT StorageWorks Router Link/ Act Fibre Channel Pwr. Link/ Act Pwr.
Introduction Note: The router implementation of the Extended Copy command is available to application programmers. See Appendix B, “Controller LUN Commands” on page 161 for additional information. Router Specifications This section lists the environmental requirements of the router.
Configuration Overview 2 The HP StorageWorks Network Storage Router 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 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.
Configuration Overview 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.
Configuration Overview For more information, see “FTP User Interface” on page 143.
Configuration Overview 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.
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.
Configuration Overview 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.
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.
Configuration Overview 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.

Basic Troubleshooting 6 This chapter discusses some basic methods of identifying faults in the setup and configuration of the HP StorageWorks Network Storage Router. Most problems are made during the initial installation of the router. Before proceeding with advanced troubleshooting techniques, verify all connections and review the configuration.
Basic Troubleshooting LED Indicators The LED indicators on the router are useful for diagnosing various problems: ■ The Fibre Channel port LEDs indicates Fibre Channel activity and link status. If one of these indicators does not light or stays continually lit without any corresponding SCSI bus activity, it may indicate a problem with the Fibre Channel link. Verify the Fibre Channel configuration. ■ The SCSI bus LEDs indicates SCSI activity.
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 Fibre Channel Port 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. When the router is connected and powered on, this link indicator should show a good link. If it does not, check the cabling or connections.
Basic Troubleshooting ■ If no devices are listed, verify the router configuration, SCSI Controller configuration, and cabling. Verifying the Router Configuration If you are in doubt about the configuration or about the location of the error, restore the router to the factory default configuration and proceed to configure the unit one step at a time, verifying the functionality of the configuration after each change is made. Caution: Restoring factory defaults overwrites user configurations.
Basic Troubleshooting Verifying HBA Device Driver Information Review the HBA device driver Readme.txt file for configuration specifics. An HBA may require a different configuration. HBAs typically come with utility programs to view or change their configurations. Verifying Serial Port Configuration Verify the configuration of the terminal or terminal emulation program.
Basic Troubleshooting Verifying PRLI Data The router returns the PRLI (preliminary login) response data as specified in Table 11. In the default configuration, the router returns PRLI Data (PRLI Accept Payload) with the Target bit SET and the Initiator bit CLEAR. However, some configurations require the Initiator bit be SET, such as in router-to-router configurations. See the Fibre Channel Overrides menu for more information about changing the initiator bit.

Controller LUN Commands B The HP StorageWorks Network Storage Router supports and executes the set of SCSI-3 commands listed in this Appendix. These commands can be received as FCP commands over the Fibre Channel 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 14.
Controller LUN Commands Table 15: Report LUNs Data Bit/ Byte 7 6 5 4 3 Least Significant Byte (LSB) 4 Reserved 5 Reserved 6 Reserved 7 Reserved 3 2 1 0 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 Inquiries report peripheral device types as 0x0c. Inquiry Command The format of the Inquiry Command is shown in Table 16.
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 Figure 17.
Controller LUN Commands Table 18: 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.
Controller LUN Commands The Extended Copy command supports the following Initiator descriptor codes listed in Table 20: Table 20: Extended Copy Initiator descriptor codes, version 00-143r1 Item Value Block to Stream 0x00 Stream to Block 0x01 Block to Block 0x02 Inline to Stream 0x04 Stream to Discard 0x06 Verify Target 0x07 Space Operation 0x11 Locate Operation 0x12 Version SPC-2 The Extended Copy command supports the following Target descriptor codes listed in Table 21: Table 21: Extende

C Addressing Methods and Table Structures Fibre Channel 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 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.
