Table 3-1 Hardware path field descriptions (continued)
For other LUN methods, the value
of this field is the Loop ID of the
target device.
For other LUN methods, the value
of this field is the least significant
byte of the N_Port ID of the target
device.
For LUNs with Peripheral Device
Addressing, the value of this field
is the upper 4 bits of the Loop ID
of the target device.
For LUNs with Peripheral Device
Addressing, the value of this field
is the upper 4 bits of the least
significant byte of the N_Port ID
of the target device.
Depends on the Fibre Channel
topology of the HBA, the target
device, and the LUN addressing
method used.
Bus
For LUNs with Logical Unit Addressing, the value is the Bus Number
field of the LUN.
For LUNs with Volume Set Addressing (Flat Space Addressing), the
value are bits 7–13 of the LUN.
With Peripheral Device
Addressing, the value of this field
is the lower 4 bits of the Loop ID
of the target device.
For Luns with Peripheral Device
Addressing, the value of this field
is the lower 4 bits of the third byte
of the N_Port ID of the target
device.
This field usually corresponds to
the Arbitrated Loop Physical
Address (AL_PA_ of the target
device.
Depends on the Fibre Channel
topology and the LUN addressing
method used.
Target
For LUNs with Logical Unit Addressing, the value id the Target field
of the LUN.
For LUNs with Volume Set Addressing (Flat Space Addressing), the
value are bits 3–6 of the LUN.
Depends only on the LUN addressing method used.LUN
