LUN Addressing Method | Value of LUN field in Fibre Channel hardwarePath. |
Peripheral Device Addressing | The Target or LUN field of the Logical Unit Number. |
Logical Unit Addressing | The LUN field of the Logical Unit Number. |
Volume Set Addressing |
|
(Flat Space Addressing) | Bits 0 - 2 of the Logical Unit Number. |
For more information about the fields in the Logical Unit Number, please see the SCSI Architecture Model - 3
Fibre Channel devices can connect to a fabric using a Direct Fabric Attach. Direct Fabric Attach devices do not have an AL_PA and the least significant byte of their N_Port ID is usually 0. This is dependent on the switch implementation. Not all switches adhere to this scheme.
Some switches enable devices in Private Loop mode to connect to a fabric. These switches typically translate the Private Loop device as a Direct Fabric Attach device to the rest of the fabric. These switches also typically translate the rest of the fabric as Private Loop devices to the Private Loop device.
