Understanding the PSFR-CP41 Configuration

Auto Addressing

Auto Addressing

The Auto Addressing option is similar to Indexed Addressing, but with the distinction that the table used is created through SCSI device discovery upon power up or reset, and not otherwise retained. As the unit performs device discovery on the SCSI bus, the Index table 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. This allows easy configuration in environments where device ordering is not important, and hot plugging of SCSI devices will not occur. Configuration allows for discovery to be performed in order of target or LUN, as desired for the specific environment.

Auto Addressing, target mode is configured as the default mode of the PSFR- CP41.

SCC Addressing

The PSFR-CP41 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 PSFR-CP41. The Access Method used is the SCC Logical Unit Addressing method.

In SCC Addressing mode, the PSFR-CP41 will respond to FCP commands, as in a SCC controller device. A subset of the SCC behavior is implemented. LUN mappings corresponding to the SCC Peripheral Device Addressing are inter- preted as controller commands, and are acted on by the PSFR-CP41 directly. LUN mappings using SCC Logical Unit addressing are routed to the appropriate SCSI BUS:TARGET:LUN and processed accordingly.

Further description of the PSFR-CP41 implementation of SCC addressing is in Appendix B.
