Understanding the PSFR-CP41 ConfigurationGeneral Fibre Channel Configu

General Fibre Channel Configuration

On a Fibre Channel arbitrated loop, the PSFR-CP41 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 PSFR-CP41 can be configured to use soft addressing (default) or hard addressing with a selected value.

Soft Addressing

When acquiring a soft address, the PSFR-CP41 acquires the first available loop address starting from address 0. In this mode, the PSFR-CP41 automatically obtains an available address and participates on the loop, as long as there is at least one address available on the loop that is connected to the PSFR-CP41. Fibre Channel supports up to 126 devices on an arbitrated loop.

Hard Addressing

When acquiring a hard address, the PSFR-CP41 attempts to acquire the AL_PA value that was specified by user configuration. If the desired address is not available at loop initialization time, the PSFR-CP41 comes up on the loop in non-participating mode. This allows the loop to continue to operate, although the unit will not be accessible via the Fibre Channel interface. This would occur when another device on the arbitrated loop has acquired the same address as that configured on the PSFR-CP41.

Hard addressing is recommended for environments where it is important that the 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 identifi- cation for proper operation. Hard addressing will insure that the device identifi- cation to the application will remain constant.

When connected to a Fibre Channel Switch, the PSFR-CP41 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.
