Revision Level Table C 1 Scalar 100 FCR 1 Module inquiry data The Scalar 100 FCR 1 Module will only reply to a SCSI Inquiry when using 8 byte LUN field of 0x00 s Once the Scalar 100 FCR 1 Module has been detected then the devices on the SCSI 2 can be detected using the SCC Logical unit addressing Appendix C ADIC Scalar 100 FCR 1 Module User s Guide Appendix 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 When a Fibre Channel initiator initializes on a loop the host must first determine what devices exist on the loop Device discovery is performed and an FCP target device list is built Each device is queried for FCP logical units The logical units are the actual devices that the operating system will address When an initiator addresses a logical unit the LUN field used is consistent in form with the SCC defined fields All current Fibre Channel host bus adapter drivers are consistent with these methods The addressing used is the SCC Logical Unit Addressing and Peripheral De

6. Introducing the ADIC Scalar 100 FCR 1 Module Designed for the Scalar 100 Library the ADIC Scalar 100 FCR 1 Module Fibre Channel to SCSI Storage Router provides connectivity between a Fibre Channel Switched Fabric FC SW or Fibre Channel Arbitrated Loop FC AL and three Fast Wide Ultra 2 SCSI buses How the Scalar 100 FCR 1 Module Works The Scalar 100 FCR 1 Module is a storage router that translates the Fibre Channel Protocol FCP to and from three SCSI buses so devices on these two types of media can communicate with each other It attaches to either a Fibre Channel or SCSI host and transfers the command data and status information to SCSI or Fibre Channel targets Packets are transferred transparently by the Scalar 100 FCR 1 Module from host to targets and vice versa The Scalar 100 FCR 1 Module provides interconnection between for three SCSI buses and a Fibre Channel Arbitrated Loop or Switched Fabric It takes advantage of Fibre Channel s ability to encapsulate SCSI protocol packets to allow a host with a FC or SCSI adapter to access SCSI or FC peripheral devices transparently over a FC connection Figure 1 1 Fibre Channel to SCSI configuration SCSI Tape Drives Fibre Channel FCR 1 Module FC Host Scalar 100 Library EEE SCSI Figure 1 1 shows a Fibre Channel to SCSI configuration Through the Scalar 100 FCR 1 Module any host on the Fibre Channel loop can access the tape drive and

48. e On a SCSI bus the Scalar 100 FCR 1 Module acts as a SCSI initiator or target passing requests from hosts on the Fibre Channel network to target devices on the SCSI bus Each Scalar 100 FCR 1 Module SCSI bus uses one or more SCSI IDs The default Initiator ID is 7 and can be changed when configuring the Scalar 100 FCR 1 Module The Fibre Channel Side In a Fibre Channel loop the Scalar 100 FCR 1 Module is identified by a single Arbitrated Loop Physical Address AL_PA or a fabric assigned Source ID Once the address is acquired any host on the Fibre Channel loop can access the devices on a SCSI bus transparently over a FC connection Mapping Devices To allow Fibre Channel and SCSI devices to address each other the Scalar 100 FCR 1 Module creates tables mapping device identifiers for Fibre Channel to SCSI and for SCSI to Fibre Channel During Scalar 100 FCR 1 Module configuration you can choose the mapping methods and in certain cases customize device mappings See Chapter 3 for more information about address modes and their configurations Chapter 1 1 4 Processing SCSI Information The following section describes how the Scalar 100 FCR 1 Module processes SCSI information Figure 1 4 illustrates steps 1 through 5 of the process 1 A FC host issues a command The FC host encapsulates the command in the FCP protocol and sends the packet to the Scalar 100 FCR 1 Module 2 The FC controller in the Scalar 100 FCR 1 Module recei
49. e 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 of such an environment would be a tape library installation where the application configuration requires fixed device identification for proper operation Hard addressing ensures that the device identification to the application remains constant When connected to a Fibre Channel switch the Scalar 100 FCR 1 Module is identified to the switch as a unique device by the factory programmed World Wide Name WWN 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 Refer to the HBA manual for the mapping table 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 In such a configuration the Scalar 100 FCR 1 Module corresponds to a Bus Target identifier with the SCSI devices attached to the Scalar 100 FCR 1 Module appearing as logical units LUNs In addition operating systems can extend the available SCSI limit of 15 per bus Although this is not an issue for the operating system or most applications
