Figure 2-6 Fibre Channel-to-SCSI Configuration Operating as Both a SCSI and Fibre Channel Device The router is both a SCSI and Fibre Channel device operating on a SCSI bus and Fibre Channel network simultaneously. The SCSI Side On a SCSI bus, the FCR200 acts as a SCSI initiator passing requests from hosts on the Fibre Channel network to target devices on the SCSI bus. Each FCR200 SCSI bus uses a single SCSI ID. The default ID is 7 and can be changed when configuring the FCR200.
Mapping Devices To allow Fibre Channel and SCSI devices to address each other, the FCR200 creates a table that maps device identifiers between Fibre Channel and SCSI. During FCR200 configuration, you can choose the mapping method and, in certain cases, customize the device mappings. See Chapter 5 for more information about address modes and their configurations. Processing SCSI Information The following describes how the router processes SCSI information. Refer to Figure 2-7 on page 2-11.
Figure 2-7 Information processing 6 Data flows between the host and target through DirectFlow payload buffers. 7 Response information flows from the SCSI target back to the FC host. Processing Fibre Channel Information The FCR200 processes information from the SCSI bus host by requesting operations of targets on a Fibre Channel Storage Area Network (SAN).

Figure 4-8 Attaching Side Rails Once the FCR200 is installed, you are ready to connect it to the other system components.
Interfaces and Connections There are four types of physical interfaces to the FCR200: • Fibre Channel • SCSI • RS-232 (Serial port) • Ethernet The RS-232 and Ethernet ports are used primarily for FCR200 configuration and management. MIB information for each interface is discussed later in this chapter.
Fibre Channel Connection Before connecting the FCR200 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 FCR200 connected to either an Arbitrated Loop or Switched Fabric environment.
Multi-Mode Fiber Support 1.0625 Gbaud Dual SC connectors Single-Mode Fiber Support1.0625 Gbaud Dual SC connectors To connect the FCR200 to the Fibre Channel Storage Area Network: 1 Figure 4-11 Fibre Channel Port 2 Figure 4-12 Locate the Fibre Channel port on the back of the FCR200. Remove the rubber protector from the GBIC, as shown in Figure 4-12, and push the metal latch down to lock it into place.
The FCR200 has been qualified with a specific set of GBICs. Using a GBIC that has not been qualified may cause the FCR200 to operate improperly or to void approval and certifications WARNING 3 4-14 Installation With the FCR200 powered off, connect the FCR200 into your Fibre Channel environment using the appropriate cabling. The connectors on the FCR200 are keyed. Be sure to insert the cable connectors in the proper orientation.
SCSI Connection The FCR200 supports Fast/Ultra Wide SCSI. The FCR200 is factory configured to support either a Single-Ended or Differential SCSI bus. Four 68-pin D-shell connectors are located on the rear panel of the unit, allowing the unit to be attached in the middle or at the end of a SCSI bus. If the FCR200 is located at one end of the SCSI bus, an external terminator should be installed. Two terminators are provided with the FCR200.
Figure 4-13 FCR200 SCSI Connection 5 Figure 4-14 4-16 Installation Make sure that each bus is terminated correctly. The device at each end of each bus must be terminated. SCSI Terminator 6 Power on your SCSI devices. 7 After all the SCSI devices have completed their individual POSTs, power on the FCR200.
Ethernet Connection 10BaseT Ethernet connectivity is used to provide enhanced management and configuration capabilities. The RJ-45 connector on the unit can be directly connected to a standard 10BaseT Ethernet network. Note The FCR200 contains a unique Ethernet MAC address that is assigned during the manufacturing process. Figure 4-15 Configuration is required to set the IP network address to allow for use of the configuration capabilities of this port.
Serial Port Connection The RJ11 connector on the rear panel of the FCR200 provides an RS-232 connection that can be used to configure the FCR200, monitor diagnostic status, or to update the program stored in the FCR200’s Flash memory. A cable is provided with the unit to connect to a DB-9 serial connection. Further information on the operations allowed via the RS-232 port is provided in Chapter 6.
Autobaud Feature Note Hitting the Enter key before the POST has completed has no effect on the autobaud feature. Wait until both the POST and the Firmware Initialization processes have completed before hitting the ENTER key. This may take up to 90 seconds. The autobaud feature automatically configures the baud rate on the FCR200. Once you set the baud rate in the terminal emulation program, wait until the FCR200 completes the Power On Self Test (POST) and then the Firmware Initialization process.
Connecting the Power Cord The power cord shipped with the FCR200 is a 120 VAC threeconductor power cord for use in the United States or Canada. If you are planning to use another input voltage or if you plan to use the FCR200 outside of the U.S. or Canada, you must supply your own power cord. To connect the power cord to the FCR200: Figure 4-17 4-20 Installation 1 Make sure the FCR200’s power is switched off. See Figure 4-17 for the location of the power switch on the back of the router.
Management Information Base (MIB) A MIB (Management Information Base) is an element used in network management with SNMP (Simple Network Management Protocol) and a management station running a management application, such as Hewlett Packard’s Open View. The management application uses GETs and SETs to get system information and set system environment variables. The ADIC private MIB can be accessed via Ethernet and is both a diagnostic and a configuration tool for the FCR200.
MIB Ethernet and Serial Interfaces Information The Ethernet interface is used for configuration and management, so total traffic flow is relatively low. The basic Ethernet configuration items are found in the Management Interfaces (MI) Table. The serial port is provided for user configuration. The serial port baud rate will be kept in the MI Table.

5-2 Understanding the Configuration 62-9301-01
5- Understanding the FCR200 Configuration Of primary importance in configuring the FCR200 is determining the mode of operation required. The unit can be configured to support Fibre Channel hosts communicating with SCSI targets, or SCSI hosts communicating with Fibre Channel targets. The default configuration of the unit allows for Fibre Channel hosts to connect to SCSI targets.
An understanding of the basic characteristics of Fibre Channel and SCSI devices is recommended before configuring the FCR200. General Fibre Channel Configuration On a Fibre Channel arbitrated loop, the FCR200 appears at a single Arbitrated Loop Physical Address (AL_PA). Fibre Channel devices support two methods for obtaining an AL_PA, these being soft or hard addressing. The FCR200 can be configured to use soft addressing (default) or hard addressing with a selected value.
When connected to a Fibre Channel Switch, the FCR200 is identified to the switch as a unique device by the factory programmed World Wide Name (WWN). No further configuration is needed, although the WWN can be configured to a user-defined value through the configuration interface. General SCSI Configuration The FCR200 appears on each SCSI bus as a single initiator. The default initiator ID is 7, and can be set via configuration to any valid SCSI address.
Note The SCSI bus number corresponds to the physical SCSI port on the back of the FCR200. Auto Addressing Automatically creates a new address mapping table every time the FCR200 is power cycled. SCC Addressing Implements the SCSI-3 Controller Commands SCSI storage array addressing to address SCSI devices attached to the FCR200. SCSI Targets are selected by mapping the appropriate values into the FCP LUN field, and correlating a Fibre Channel LUN value to a SCSI Bus:Target:LUN value.
Table 5-1 Indexed Addressing FPC LUN Value SCSI BUS:TARGET:LUN 14 0:15:0 15 0:0:1 16 0:1:1 (…) (…) The Indexed Addressing table has the structure shown in Table 5-1. The FCR200 will allow up to 80 device entries to be mapped. The index table can be manually edited, and is then saved to FLASH memory. Configuration assists allow for the table to be filled in order of increasing target, or LUN, as may be desired for the specific requirements needed.
SCC Addressing The FCR200 implements the SCSI-3 Controller Commands (SCC) (X3T10 Project 1047D Revision 6b 01-July-96) SCSI storage array addressing to address SCSI devices attached to the FCR200. The Access Method used is the SCC Logical Unit Addressing method. In SCC Addressing mode, the FCR200 will respond to FCP commands, as in a SCC controller device. A subset of the SCC behavior is implemented.
Table 5-2 SCSI-to-Fibre Target:Channel Address Mapping SCSI BUS:TARGET:LUN Fibre Channel AL_PA LUN 0:4:1 0x10 0 0:4:2 0x17 0 0:4:3 0x18 0 The Index Table is edited to represent the desired mapping, and saved to FLASH memory. Note In addition to configuring the address mapping, SCSI-to-Fibre Channel mode requires that a SCSI interface on the FCR200 be configured to respond to specified SCSI IDs. This is done through the SCSI configuration menu.

6- Configuring the FCR200 A menu structure is used to configure the FCR200 through the serial and telnet interfaces. The currently selected menu and the firmware version currently executing will be displayed. Menu items are selected by entering the number of the menu desired, and exited by entering an ‘X’. In general, the configuration options present in the serial interface correspond to those available through SNMP and telnet. Note Menus are not case sensitive.
Operation Indicators The FCR200 router is equipped with rear panel LED indicators for monitoring overall router status. The LED functionality is detailed below. See Figure 6-1. Figure 6-1 6-4 Configuration Power This green indicator turns on when power is applied to the router. Fault This amber indicator lights up during POST, then remains dark unless the FCR200 experiences a processor problem. SCSI 1 This green indicator signifies SCSI 1 activity when lit.
Host Device Configuration The host system using a Fibre Channel Host Bus Adapter (HBA) will typically map Fibre Channel devices into the existing device mapping scheme used by that operating system. This usually results in the Fibre Channel HBA mapping Fibre Channel AL_PA’s to SCSI target addresses. The HBA will claim enough SCSI bus entries to allow for 125 Fibre Channel targets to map to SCSI Bus:Target entries. This is usually done by a fixed mapping of AL_PA to Bus:Target.
Ethernet The 10BaseT Ethernet port must first be configured via the serial port with an appropriate IP address and subnet mask prior to use unless the default values are to be used. Default values are IP address 1.1.1.1, and a subnet mask of 255.255.255.0. SNMP The FCR200 includes SNMP management support. SNMP is transported via the Ethernet connection (10BaseT port). SNMP support allows configuration and management using any standard SNMP management tool. SNMP data is defined in the SNMP MIB.

When configuring Indexed addressing, the user is presented a table with the current mappings. The user can then select a table entry by FCP LUN and specify the associated BUS:TARGET:LUN. Alternately, the user can fill with one of multiple preset patterns, or with the list of currently attached SCSI devices. The user then saves these values in FLASH memory, where they are retained across future device resets or power cycles.
SCSI-to-Fibre Channel Mapping Configuration This option allows modification of the table mapping SCSI Target:LUN values to Fibre Channel Node:LUN values. Configuration of these devices is similar to that for indexed addressing, without the user assists. Prior to configuring these tables, the user must enable the SCSI target and initiator addresses desired to enable the mapping for that SCSI device. Trace Settings Configuration This option allows trace levels to be set.
Reset Configuration to Factory Defaults This option resets all configuration options to the factory defaults. Display POST Status This option displays the results of the most recent power on self test (POST). The POST test results are shown below.

Configuring the FCR200’s Ethernet Port If you plan to use Ethernet to configure the FCR200, you must first set up serial communications with the FCR200 to configure the Ethernet port’s address. The FCR200 provides an Ethernet port for connection to a standard 10BaseT Ethernet network. You can use Ethernet to perform the following activities: • Configure the FCR200 through Telnet. The configuration menus accessed via the serial port will be disabled when a telnet session is connected.

7-2 Troubleshooting 62-9301-01
7- Troubleshooting Various problems can arise when configuring and using the FCR200. 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.
• The Fibre Channel indicator shows Fibre Channel activity when lit. If this indicator fails to light at all, or stays continually lit without corresponding SCSI bus activity, it may indicate a problem with the Fibre Channel link. Verify the Fibre Channel Configuration. • The Ethernet indicator signifies Ethernet activity when lit. If the light fails to flicker, or if it stays continually lit, it may indicate a problem with the network connection. Verify the network connection.
• SCSI Devices – Verify SCSI devices can be seen in the configuration menu of the FCR200. Select “Perform Configuration” from the first menu. Then select “Fibre Channel to SCSI Mapping Configuration.” You must then enter a “1” for LUN priority, “2” for Bus priority, or a “3” for Target, in order to view the list of SCSI devices. If the FCR200 can not see the devices, verify SCSI configuration and cabling.
Verify Configuration A number of configuration changes may result in an invalid configuration. If you are in doubt about the configuration, restore the FCR200 to the factory default configuration and proceed to configure the unit a step at a time, verifying the functionality of the configuration as changes are made. Verify Addressing If working in FC-to-SCSI target mode and using Indexed or SCC Addressing, try swapping to Auto Addressing to see if this solves the problem.
RS-232 Port Problems If you experience trouble communicating with the RS-232 port, verify the host terminal emulation configuration. The FCR200 requires the baud rate to be set correctly, 8 data bits, 1 stop bit, and no parity. Flow control should be disabled, and may cause problems if set to ‘hardware’ or XON/XOFF. Some hosts may not support baud rates higher than 19200, so a lower baud rate may be required. If problems persist, you may want to check the cabling or try a different host.

B-2 Fibre Channel Interface and Commands 62-9301-01
B- Fibre Channel Interface and Commands Download Command The Update Firmware command is used to download firmware to the FCR200 over Fibre Channel. Multiple Update Firmware Write Buffer commands will be required to accomplish the total transfer. All write commands except the final write will have 3-bit Mode field set to 0x06. The last write command in the sequence will have the Mode bits set to 0x07 to signify the end of transfer. Each Update Firmware write buffer command will return an FCP response.
Table B-1 Bits Bytes 7 Download Write Command Buffer 6 5 4 3 12 D (0x44) 13 A (0x41) 14 T (0x54) 15 E (0x45) Note Multiple Update Firmware commands will generally be required to transfer the entire program image from the host to the FCR200 DRAM. When the last data block is transferred (mode = 0x07) the FCR200 terminates data transfer and performs a CRC checksum on data received.
Report LUNs Command In SCC mode, the FCR200 supports the Report LUNs command. The Report LUNs command will return a list of Logical Unit Numbers that can receive commands.
Table B-3 Bits Bytes Report LUN Parameter List 7 6 5 0 : 7 4 3 2 1 0 First LUN : Last LUN Note The LUN list length is the number of LUNs times 8. PRLI Data The FCR200 supports the discovery mechanism as described in the standard “Private Loop SCSI Direct Attach Rev. (section 10.3 - Target Discovery)”. The FCR200 returns the PRLI response data as specified in Table B-4.

D-2 Addressing, Structures, and Operation 62-9301-01
D- Addressing, Structures and Operation Fibre Channel and SCSI systems employ different methods of addressing devices. The inclusion of a bridge or 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.

Indexed Addressing Option Note Indexed Addressing allows for host bus adapter drivers that only use Peripheral Device addressing to access SCSI devices attached to the FCR200 unit. 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 FCR200 unit as a controller unit directly when using the Indexed Addressing option.
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 a SCSI bus, the Index table relating FCP LUN values is filled with adjacent FCP LUNs referencing each subsequent SCSI device. The host system will then detect every attached device without voids, allowing full device discovery to the host.
