Fibre Channel Adapter Installation for HP-UX
Interpreting Lunpath Hardware Paths (HP-UX 11i v3)
Chapter 1

The controller, target, and lun values are extracted from the LUN id as shown in the table:
To convert a lunpath hardware path to a legacy hardware path, use the scsimgr get_info command on the
target’s hardware path to display the port_id, which contains the domain, area, and port values. Extract the
controller, target, and lun values from the LUN id.
The following example uses lunpath hardware path 0/2/1/0.0x500805f300083899.0x4011000000000000:
# scsimgr get_info -H 0/2/1/0.0x500805f300083899
STATUS INFORMATION FOR TARGET PATH : 0/2/1/0.0x500805f300083899
Generic Status Information
SCSI services internal state = IDLE
Port id = 0x10700
Protocol = fibre_channel
Protocol revision = 4.3
Port name = 0x500805f300083899
Node name = 0x500805f300083890
LUN paths registered (active/inactive) = 12
A port_id of 0x10700 yields a domain value of 1, an area value of 7, and a port value of 0.
The LUN address of 0x4011000000000000, which represents LUN id 0x11, yields a controller value of 0, a
target value of 2 and a lun value of 1.
The resultant legacy hardware path is 0/2/1/0.1.7.0.0.2.1.
To confirm this mapping, use the ioscan –m hwpath command, as follows:
# ioscan -m hwpath -H 0/2/1/0.0x500805f300083899.0x4011000000000000
