= Idle

The controller, target, and lun values are extracted from the LUN id as shown in the table:

Table 1-7

Controller	Target	LUN
(7 bits)	(4 bits)	(3 bits)

0-63	0-15	0-7

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
