Fibre Channel part (N_Port ID)
This part comprises of the new 8 bit fields Domain, Area and Port. In general these
fields are used to hold the N_Port ID. This 3 byte value can be regarded as the
equivalence to the fixed 6 byte Media-Access Control identifier (MAC address) in the
LAN world. In case of a fabric topology (a switch is present) the switch assigns the
N_port ID dynamically during login and stores the information it’s private name
server table.
Domain:
The Domain ID usually identifies the instance of the switch in a fabric environment.
For private loops the value is 8.
Area:
In a fabric environment, the Area ID is generally associated with a physical port on a
switch. For private loops, the value is 0.
Port:
When interpreting the hardware path for FCMS devices, arrays are defined as having
addressable controllers, and non-arrays are defined as not having addressable
controllers. For hardware paths associated with non-array LUNs, the Port ID is set to
the value 255 (255 for direct connect controller). For hardware paths associated with
array LUNs, the Port ID is set to the Loop ID, for a private loop topology, AL_PA for
public loop topology or 0 for direct fabric attach.
但对Area_ID (8 bit)在Direct Fabric Attach或public loop模式下的值描述为：
the physical connector (slot) on the switch. For Brocade subtract 16 from the Area ID to get the slot number
是在borcade交换机下要减去16才得到solt number,民工兄，你的switch board的说法是从什么资料中看到的？我还是有点不明白这个地方。 |
