Understanding the FCR200 Configuration 5-3 5- Under standing 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.
5-4 Understanding the Configuration 62-9301-01 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).
General SCSI Configuration 5-5 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.
5-6 Understanding the Configuration 62-9301-01 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.
Auto Addressing 5-7 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.
5-8 Understanding the Configuration 62-9301-01 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.
SCSI Host to Fibre Channel Target Configuration 5-9 The Index Table is edited to represent the desired mapping, and saved to FLASH memory. 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.

SCC Addressing Option D-5 SCC Addressing Option When the FCR200 is configured to use SCC addressing, the unit is capable of responding as a controller device to the FCP Initiator, or routing the FCP request to a specified BUS:TARGET:LUN triplet.
D-6 Addressing, Structures, and Operation 62-9301-01 Inde xed Addressing Option 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.
Auto Assigned Addressing Option D-7 A uto 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.
