1-1 Chapter 1 Introduction The HP VT5900-SA Virtual TapeServer SCSI-to-FC Adapter provides bi-directional connectivity between a Fibre Channel Switched Fabric (FC-SW) or Fibre Channel Arbitrated Loop (FC-AL), and two Narrow/Wide Fast/Ultra-3 SCSI buses.
1-2 Operation Indicators The VT5900-SA is equipped with rear panel LED indicators for monitoring overall unit status. Figure 1-3.
1-3 Processing SCSI Information The following section describes how the VT5900-SA processes SCSI information when attached to FC hosts. Figure 1-5 illustrates steps 1 through 5 of the process. 1. An FC host issues a command. The FC host encapsulates the command in the FCP protocol and sends the packet to the VT5900-SA. 2. The FC controller in the VT5900-SA receives the packet, interprets the FC information, and places the packet in buffer memory. 3.

2-5 Figure 2-4. Mounting at front of rack Front of mounting bracket Figure 2-5. Mounting at back of rack Front of mounting bracket Once the VT5900-SA is installed, you are ready to connect it to the other system components.
2-6 Installation Procedure with Rails 1. Remove the VT5900-SA from the protective bag. 2. Determine where the VT5900-SA will be mounted. Note: Place the VT5900-SA so the front exhaust vents and the rear intake vents remain clear of obstructions to ensure proper airflow. 3. Remove any blanking panels and other equipment from the chosen rack location. 4. Select the rail pieces as shown in Figure 2-1 and adjust the lengths to the size of the rack.
2-7 Figure 2-7. Attaching rails to the VT5900-SA 6. Attach the VT5900-SA to the rack by inserting the slide rails at the sides of the VT5900-SA into the extension brackets you attached to the rack in Step 4. Slide the rails into the brackets as shown in Figure 2-8 below until the rails lock into place. Press in the spring latches on each side of the VT5900-SA and then push it the rest of the way into the rack. Warning: To reduce injury or equipment damage, the rails must be level.
2-8 Interfaces and Connections There are four types of data interfaces to the VT5900-SA: • Fibre Channel • SCSI • RS-232 (RJ-11 Serial port) • Ethernet The RS-232 and Ethernet ports are used primarily for VT5900-SA configuration and management. Figure 2-9.
2-9 Fibre Channel Connections Before connecting the VT5900-SA to other Fibre Channel devices, it is important to understand the configuration requirements of the environment to which it will be connected. Failure to correctly configure a Fibre Channel device may impair the operation of the Storage Area Network to which it is attached. Typical installations will have the VT5900-SA connected to either Arbitrated Loop or Switched Fabric environments.
2-10 2. Remove the rubber protectors from the SFFs, as shown in Figure 2-13. Figure 2-13. Removal of SFF protectors SFF Protector SFF 3. With the VT5900-SA powered off, connect the VT5900-SA into the Fibre Channel environment using the appropriate cabling. The FC optical connectors on the VT5900-SA are keyed. Be sure to insert the cable connectors in the proper orientation. SCSI Connection The VT5900-SA can support Fast/Ultra-3 Narrow/Wide SCSI, depending on the specific configuration.
2-11 Figure 2-14: High density SCSI cables Warning: During attachment of high density SCSI cables, please note the orientation (as shown in Figure 2-14) of the high density SCSI port connectors on the back panel of VT5900-SA. Failure to maintain appropriate orientation of the cables to the SCSI port connectors can result in damage to the SCSI port connectors on the VT5900-SA. Caution: SCSI ports on the VT5900-SA are not hot-pluggable.
2-12 Figure 2-15. VT5900-SA SCSI connection SCSI buses 4. Power on the SCSI devices on this bus, but not the VT5900-SA. 5. After all the SCSI devices on this bus have completed their individual POST (Power-On Self Test) processes, power on the VT5900-SA. Ethernet Connection 10/100BaseT Ethernet connectivity provides enhanced management and configuration capabilities. The RJ-45 connector on the unit can be directly connected to a standard 10/100BaseT Ethernet network.
2-13 Serial Port Connection The RJ-11 connector on the back panel of the VT5900-SA provides a serial port that is compatible with RS-232 signaling levels. The VT5900-SA is designed to communicate with a terminal or any operating system utilizing a terminal emulator. The baud rate, data bits, stop bits, parity, and flow control of both the VT5900-SA and the host system must use the same settings.
2-14 Setting Up Serial Port Communications Leave the VT5900-SA turned off until you have set up the serial port communications on your host computer, unless serial I/O was previously established and is currently running. The VT5900-SA is designed to communicate with a terminal or any operating system utilizing a terminal emulator. For example, Windows 9x, NT 4.0, Windows 2000, Windows XP, and some other Windows operating systems can use HyperTerminal.
2-15 Connecting the Power Cable The power supply used with the VT5900-SA supports 100 - 240 VAC (Auto Sensing), but the correct type of power cable needed for your installation should still be verified. The power cable shipped with the VT5900-SA is a 120 VAC 3-conductor power cable for use in the United States and Canada. This is the power cable that should be used with the VT5900-SA unless your installation requires otherwise, in which case you should supply the appropriate power cable as needed.
2-16 Chapter 2: Getting Started
3-1 Chapter 3 Configuration Procedures The VT5900-SA can be configured in a variety of ways. The following are general procedures for setting up basic operational status. Not all of these exact settings will apply to every environment, but this section of the manual should provide guidance for some of the basic considerations that need to be made when configuring the VT5900-SA. Quick Setup from the Visual Manager Interface 1. Set the IP address using the serial interface. a.
3-2 7. Verify that SCSI ID 7 is not in use by any devices being attached to the VT5900-SA. If ID 7 is used, then set the Initiator ID to a value different from any SCSI IDs already in use on the SCSI bus of the devices you are attaching to the VT5900-SA. Initiator ID “7" is the default SCSI ID used on the VT5900-SA. To change the Initiator ID, select the appropriate SCSI bus and then select a SCSI ID that is not in use by any device(s) attached to the VT5900-SA. When finished, select the Submit button. 8.
3-3 4. To enable remote management capabilities, change the Ethernet settings to “DHCP enabled” or enter a valid IP address and IP gateway so the VT5900-SA is configured properly for network operation. Select menu option 2 from the configuration menu to access Ethernet settings. 5. Select the letter A to save your configuration changes to the VT5900-SA. Once the VT5900SA saves your configuration changes, enter X to exit to the Main menu. 6. Select menu option 4 to reboot the VT5900-SA.
3-4 Chapter 3: Configuration Procedures
4-1 Chapter 4 Addressing and Logical Unit Management To provide connectivity between hosts and devices, it is necessary for the VT5900-SA to establish itself with an address on each connected Fibre Channel network and SCSI bus. SCSI Bus Configuration The VT5900-SA provides the capability to reset SCSI buses during the VT5900-SA boot cycle. This allows the devices on a SCSI bus to be in a known state. Configuration provides for the SCSI bus reset feature to be enabled or disabled.
4-2 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 VT5900-SA. Soft addressing is the default setting. For hard addressing, the user specifies the AL_PA of the VT5900-SA.
4-3 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 VT5900-SA to Manual Discovery Only. For specific information on Discovery settings, see the Fibre Channel Configuration and SCSI configuration sections in “Chapter 5, VT5900-SA Management” and “Chapter 6, Using Visual Manager.
4-4 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. Each port on the VT5900-SA has a set of maps which include both user defined maps and a few special predefined maps. There are currently three special predefined maps: Indexed, Auto Assigned, and SCC maps. Until a user configures the VT5900-SA otherwise, the default setting is Auto Assigned.
5-1 Chapter 5 VT5900-SA Management The VT5900-SA can be managed over the following user interfaces: • Over the serial port via a terminal or terminal emulation utility. • Over Ethernet via a Telnet utility, an HTTP-based interface called Visual Manager, or an SNMP management tool. Further, FTP support provides additional management functionality. Before attempting to configure the VT5900-SA, a basic understanding of Fibre Channel and SCSI devices is recommended.
5-2 Ethernet The 10/100BaseT Ethernet port must first be configured via the serial port with an appropriate IP address, subnet mask, and gateway prior to use unless the default values are to be used. The VT5900-SA is configured by default to use DHCP. When setting the IP address for the VT5900-SA, there are two options. (Both are described in Chapter 7 in the section on “Ethernet and SNMP Configuration”.) The first option is to enter a fixed, or permanent, IP address for the VT5900-SA.
5-3 3. Enter root for the default user name and password for the default password. It is recommended that you change the user name and password as soon as possible, using the Visual Manager or serial/telnet interface. 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.
5-4 Extended Copy. When using these commands, they must be sent to the Controller LUN of the VT5900-SA. For more information, see “Appendix BController LUN Commands”. This completes “Chapter 5, VT5900-SA Management”.
6-1 Chapter 6 Using Visual Manager This chapter describes the Visual Manager. The current configuration and operating status of the VT5900-SA can be accessed from many standard Web browsers, after the user logs in with the appropriate username and password. 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/.
6-2 Note: To access Visual Manager, the VT5900-SA must be assigned an IP address. The factory default setting for the IP address allows access on a local area network only. If the factory default for the IP address is already used by another device on the local network, the IP address must be changed. For remote access from WAN or Internet locations, the IP address must be changed to an appropriate IP address, with the form x.x.x.x where each x is an integer in the range of 0 to 255. 6.
6-3 It is recommended that you navigate only using the Web page links contained in Visual Manager itself. Depending on the Web browser used, these links will often appear as highlighted text. By clicking on these links, Visual Manager can be safely navigated. When Visual Manager for the VT5900-SA is accessed, the VT5900-SA home page appears as follows. Figure 6-1. Visual Manager home page Figure 6-2. VT5900-SA image A port-side view of the VT5900-SA is shown on the home page.
6-4 Figure 6-3. Navigation Bar The navigation bar on the left side of the VT5900-SA home page provides a list of menu items that are links to various VT5900-SA functions, information, and other menus.

8-1 Chapter 8 Using the FTP Interface This chapter describes specific management options available from the FTP interface. For an overview of using the other management interfaces available, see ““Chapter 5, VT5900-SA Management”.” Backup/Restore Configuration Settings The VT5900-SA supports backup and restore of configuration settings over FTP. This allows users to maintain multiple setting configurations externally from the VT5900-SA and to be able to restore any of the configurations as needed.
8-2 The file will transfer to the current directory specified on your computer’s FTP utility. If running FTP from a DOS or Linux command line, the destination directory can be set using the lcd command (ex. lcd c:\myCfg). Note: World Wide Name (WWN) values and Ethernet physical address (MAC address) values will not be saved. Because user defined values for these settings are not retained in the configuration backup file, they must be re-entered after the configuration is restored.
8-3 Get a Copy of Trace Buffer Using the following procedure, you can save copies of the trace buffers over FTP. 1. Connect the VT5900-SA to the ethernet network used by your computer. 2. Start your FTP program using the VT5900-SA’s IP address: ftp Note: You may also need to specify the directory location on your computer or network where your FTP program will store the trace file.
8-4 4. Specify binary mode: bin 5. Specify the firmware’s path and filename (.dlx file) with the put command: put The file will transfer and the VT5900-SA will reboot. The VT5900-SA will then be using the new firmware. Note: You may want to confirm the new firmware level by checking the reboot messages on the VT5900-SA through the serial interface. This completes “Chapter 8, Using the FTP Interface”.
9-1 Chapter 9 Troubleshooting Various problems can arise when configuring and using the VT5900-SA. 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 unit. 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.
9-2 Activity indicator stays continually lit without corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify the SCSI bus configuration. • Ethernet (10/100)—When lit, these green indicators signify Ethernet link status and 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.
9-3 Windows 2000 Driver Problem There are no actual device drivers required for the HP VT5900-SA Virtual TapeServer SCSI-toFC Adapter. When Windows 2000 prompts for a device driver, this situation occurs because the Active Fabric LUN of the VT5900-SA is enabled. Set the LUN in question to value of 0, in order to eliminate further Windows driver requests. You can also accept the Windows prompts and disable the device in the device manager.
9-4 and wide devices are on the same bus are common. Check to make sure that there are no loose terminators. All terminators should be firmly attached. • Device ID—Each device on a SCSI bus must have a unique ID. Also check the configured ID’s for the VT5900-SA to verify these are not in use by other devices on the same SCSI bus. • Cabling—Check SCSI cables to verify they are functional. SCSI rules for total length, distance between devices, and stub length must be adhered to.
9-5 Verify Mapping Verify that all desired devices have been discovered and mapped. If using Indexed or SCC mapping, try swapping to Auto-assigned to see if this solves the problem. Verify Devices It may be useful to connect the SCSI target devices you are attempting to use to the native SCSI interface to verify that the devices are functional. SCSI target devices can be connected to a host SCSI bus to verify they are functional.

C-1 Appendix C Addressing, Structures, and Operation Fibre Channel and SCSI systems employ different methods of addressing devices. The inclusion of a VT5900-SA 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.
C-2 Table C-4. Peripheral Device Addressing Bit Byte N 7 6 0 5 4 0 3 2 1 0 Bus N+1 Target/LUN The VT5900-SA supports the Peripheral Device Addressing Method and the Logical Unit Addressing Method, depending on the configuration. Table C-5.
C-3 Auto Assigned Addressing Option The Auto Assigned option is similar to the Indexed addressing, but with the distinction that the table used is created through SCSI device discovery on power up or reset, and not otherwise retained. As the unit performs device discovery on the SCSI bus, the Index table FCP LUN values are filled with adjacent FCP LUNs referencing each subsequent SCSI device.
C-4 Table C-6. Indexed Addressing Table FCP LUN Value SCSI BUS:TARGET:LUN 0 0:0:0 1 0:1:0 2 0:2:0 3 0:3:0 4 0:4:0 5 0:5:0 6 0:6:0 (0:7:0 occupied by Initiator ID) 7 0:8:0 (...) (...) 13 0:14:0 14 0:15:0 15 1:0:0 16 1:1:0 17 1:2:0 (...) (...
C-5 the VT5900-SA (using the Peripheral Device Addressing Method), and the VT5900-SA returns a table indicating attached devices. The host can then perform actions on these VT5900-SA attached devices directly without having to perform discovery by issuing commands through all possible combinations. This completes “Appendix C, Addressing, Structures, and Operations”.

E-1 Appendix E Management Information Bases The VT5900-SA supports two Management Information Bases (MIBs) for management using SNMP: the Fibre Alliance (FA) MIB and the Enterprise MIB. A Management Information Base (MIB) contains complete descriptions of the different types of information that can be exchanged between the VT5900-SA and a management application using SNMP (Simple Network Management Protocol).
E-2 3. Do a SET operation on the connUnitName leaf making sure to use the community SET string shown in the Serial/Telnet SNMP Configuration menu. 4. Repeat these steps for each connUnitInfo, connUnitContact, and connUnitLocation. Setting Port Name Information It is recommended to name ports based on what each port connects to. For example, a port might be connected to a terabyte RAID storage array and so the name should reflect something about this terabyte RAID storage array.
E-3 Viewing the Event Log From the network management application or SNMP MIB browser, it is possible to view the event log of the VT5900-SA from the connUnitEventTable leaf. Format of event log entry: Event Severity, Type, OID Value. • Event Severity is an integer in the range of 0 to 9 and correspond to the filter values selected from the FA MIB 2.2 Event Filter Settings menu selected from the SNMP Configuration menu.

E-18 Appendix E: Management Information Bases
F-1 Appendix F Enabling DHCP on the VT5900-SA 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 (router, client host, etc.) on a non-permanent, dynamic basis. DHCP makes network administration easier—the larger the network, the greater the benefit.
F-2 3. A default gateway: This is used to specify the address for the nearest VT5900-SA that is used by the host device to forward addressed packets on to the network. These previous three options (IP address, subnet mask, and gateway) are necessary for effective DHCP. Note: For more information about DHCP, refer to documents RFC 2131 and RFC 2132. Setting up DHCP VT5900-SA uses three different interfaces that can be used to enable DHCP: Serial, Telnet, and HTTP.
F-3 • Select 1. The following menu appears: Figure F-2: Configuration menu Configuration Menu X.X.
F-4 • Select: 2. The following menu appears: Figure F-3: Ethernet configuration menu Ethernet Configuration Menu X.X.XX XXXXXX XXXXXX-XXX_XXXXXXXXXXXXXX 01/06/2006 08:56:22 IP Address : 1.1.1.1 Subnet Mask : 255.255.255.0 IP Gateway : 0.0.0.
F-5 Use the following steps to save the current settings and reboot the system: 1. Select X) Return to previous menu 2. Select A) Save Configuration 3. Select X) Return to previous menu 4. Select 4) Reboot After the VT5900-SA finishes rebooting, the Main Menu will appear. DHCP status can be verified from the Ethernet Configuration Menu where DHCP Configuration is indicated as “Enabled” if DHCP has been successfully activated.
F-6 Special Note Regarding Ethernet IP, Subnet Mask, and Gateway Addresses Once DHCP is enabled, any “null” readings are acceptable for these 3 options before reboot. Also, the Ethernet Configuration Menu will not allow for changing these 3 options (since they are automatically configured by DHCP). As a result, the Ethernet Configuration Menu will display without these options listed. Here’s an example of this “DHCP-enabled” menu.
F-7 Visual Manager To access the HP VT5900-SA using the Visual Manager interface, first look up the current IP address within the Ethernet Configuration Menu using the Serial interface. Next, type the IP address in the Web browser without using “www” or “/” or any other characters or symbols. See “Visual Manager Troubleshooting” at end of this Appendix if there are any HTTP difficulties associated with user name and password.
F-8 • Within SNMP/MIB browser: the user will get only “Abort” messages after attempting to contact any IP address using the miethernet IPAddr leaf. “Remote SNMP agent not contacted” will also display in lower left corner of MIB browser.

GL-1 Glossary A adapter A printed circuit assembly that translates data between the FC host processor’s internal bus and a different bus, such as SCSI. address See SCSI Addressing. addressing mode Used to create a mapping table that maps devices on the SCSI bus to Fibre Channel logical units. AL_PA Arbitrated Loop Physical Address. A unique one-byte valid value, derived and used in an Arbitrated Loop Topology as defined in ANSI specification FC_AL ver 4.5.
GL-2 D device See FC Device or SCSI Device. differential An electrical signal configuration using a pair of lines for data transfer. The advantage of differential compared to single-ended configuration is a relative high tolerance for common-mode noise and crosstalk when used with twisted pair cables. In layman’s terms, this means longer distance. domain A FC term describing the most significant byte in the N_Port Identifier for the FC device. It is not used in the FC-SCSI hardware path ID.
GL-3 FC-SCSI hardware path ID A FC term describing a list of values showing the physical hardware path of the FC host to the target device. Format: Bus_Converter/ Adapter_Address.Protocol_Type.Area.Port.Bus.Target.LUN Example: 8/4.8.0.0.2.4.0 fiber A fiber optic cable made from thin strands of glass through which data in the form of light pulses is transmitted (LASER, LED).
GL-4 G gigabit interface connector (GBIC) A physical component that manages the functions of the FC-0 layer, which is the physical characteristic of the media and interface, including drivers, transceivers, connectors, and cables. Mounts on a FC adapter card and connects the VT5900-SA to a FC host. Also referred to as a Physical Link Module (PLM). H hardware path See FC-SCSI Hardware Path ID. host bus adapter (HBA) See FC Adapter.
GL-5 loop address A FC term indicating the unique ID of a node in Fibre Channel loop topology, sometimes referred to as a Loop ID. Also a status type in the FC Status Menu, showing the FC Loop Address of the VT5900-SA. loop port (nl_port) A FC port that supports loops. LUN Logical Unit Number or Logical Unit; a subdivision of a SCSI target. For SCSI-2, each SCSI target supports up to sixteen LUNs (LUN-0 to LUN-15).
GL-6 node name A field value under the FC Status Menu. The unique FC identifier, a 64-bit value, the factory assigns to the VT5900-SA. O offline Taking the VT5900-SA offline indicates that all SCSI and FC adapters in the VT5900-SA are offline. Taking a SCSI adapter offline means ending inputs/outputs and suspending all transactions going from the VT5900-SA to the specified SCSI devices. The SCSI adapter is no longer active or available for access.
GL-7 R reset SCSI For a specific SCSI bus, the host clears all inputs and outputs and then resets the bus and all the devices connected to it. responder The logical function in an N_Port responsible for supporting the exchange initiated by the originator in another N_Port. A FC responder is comparable to a SCSI target. The VT5900-SA is often the responder.
GL-8 Glossary SCSI bus The means of transferring SCSI data between SCSI devices. It is an 8-bit or 16-bit bus that supports up to eight or sixteen devices (including itself), in any mix of initiators and targets, with the limitation that at least one initiator and one target must be present. SCSI device A single unit on the SCSI bus, identifiable by a unique SCSI address. A SCSI device can act as an initiator or target. For SCSI-3, each SCSI device supports up to sixteen LUNs.
GL-9 T TCP Transmission Control Protocol target A device (usually a peripheral) that responds to an operation requested by an initiator (usually a host system). Peripherals are targets, but for some commands (for example, a SCSI COPY command), the peripheral may need to act temporarily as an initiator. terminator block/ termination An electrical connection at each end of the SCSI bus composed of a set of resistors (or possibly other components).
