Determining Controller Number from HBA Port WWN

From the WWN of the HBA port, you can determine the controller number or the controller path. In this example, the HBA port WWN is 10000000c9722de0 (as in the previous section):

# fcinfo hba-port 10000000c9722de0
HBA Port WWN: 10000000c9722de0
        Port Mode: Initiator
        Port ID: 10100
        OS Device Name: /dev/cfg/c4
        Manufacturer: Emulex
        Model: LPe11002-S
        Firmware Version: LPe11002-S 2.82a4
        FCode/BIOS Version: Boot:5.02a1
        Serial Number: 0999BG0-07500002OH
        Driver Name: emlxs
        Driver Version: 3.1.01.0 (2016.05.23.12.00)
        Type: N-port
        State: online
        Supported Speeds: 1Gb 2Gb 4Gb 
        Current Speed: 4Gb 
        Node WWN: 20000000c9722de0
        NPIV Not Supported
-bash-4.3# 

The line labelled OS Device Name indicates that the controller number is 4 (the controller device path is /dev/cfg/c4).
