Description: Top

The Sun FiberChannel Host Bus Adapters (HBAs) do not report their World Wide Number (WWN) during the boot cycle. Therefore, acquiring the WWN of the HBA is not straight forward during setup. There are several ways to find the WWN. This document is an attempt to consolidate these methods in one location.

Document Body: Top

Method 1

The WWN is stamped on the HBA. Record the WWN prior to inserting the HBA into the system.

Method 2

The Storage Area Network (SAN) foundation software must be installed for this method to work. If you already have a device attached to the HBA, you can get the WWN using 'luxadm' commands. The steps, with an example, are as follows:

1) Use luxadm to display the path:

     # luxadm -e port

Found path to 1 HBA ports

      /devices/pci@4,4000/SUNW,qlc@4/fp@0,0:devctl    CONNECTED

NOTE: If the path does not report CONNECTED, it means that no devices are attached to the HBA. Therefore, the following 'luxadm dump_map' command will not report the WWN for the HBA.

2) Using the path shown in the previous command, use 'luxadm' to report the WWN:

     # luxadm -e dump_map /devices/pci@4,4000/SUNW,qlc@4/fp@0,0:devctl

     Pos AL_PA ID Hard_Addr Port WWN         Node WWN       Type

     0     2   7c    0   210000e08b05b4c1 200000e08b05b4c1 0x1f (Unknown Type)
     1     d9  8     d9  50020f230000a81b 50020f200000a81b 0x0  (Disk device)
     2     1   7d    0   210000e08b052b82 200000e08b052b82 0x1f (Unknown Type,
                                                                 Host Bus Adapter)

Note: The HBA is the device notated as "(Unknown Type, Host Bus Adapter)." The Port and Node WWN are reported. The Port WWN is the number to use for LUN-masking.

In this example, the WWN of the HBA is 210000e08b052b82.

Method 3

If no devices are connected to the HBA port, connect a cable from the HBA port to a switch port. The switch reports the WWN of any device connected to the port. The command to display the HBA's WWN will vary depending upon the switch type.

Method 4

The WWN is reported at the "ok" prompt as part of the device properties. This method requires the host to be shutdown. Ensure HBA firmware is up to date prior to use of this method.

1) If the system is not at the "ok" prompt, execute the following:

     # init 0

2) Once at the "ok" prompt:

       ok  cd /devices/pci@4,4000/SUNW,qlc@4
       ok  .properties

This is an example of the output. You can see the 'port-wwn' is listed.

Method 5

To receive the WWN from the following command, make sure that the SFK ( SAN Foundation Kit ), its patches and all applicable HBA firmware are installed. Your system will need to rebooted with the reconfigure option.

prtconf -vp|grep -i wwn - will provide the wwn of all configured HBAs on the system this is a snapshot of what the prom saw at boot.

#prtconf -vp|grep -i wwn
port-wwn: 210000e0.8b0706a7

node-wwn: 200000e0.8b0706a7

port-wwn: 210100e0.8b2706a7

node-wwn: 200000e0.8b2706a7

port-wwn: 210100e0.8b243b0f

node-wwn: 210100e0.8b243b0f

port-wwn: 210000e0.8b043b0f

node-wwn: 210000e0.8b043b0f

Method 6

PRTPICL (get HBA properties, including WWN if "NOT CONNECTED" in 'luxadm -e port')

prtpicl -v -c scsi-fcp (for just Sun QLogic & Sun Emulex) } prtpicl will not show Emulex WWN (6297103)

prtpicl -v -c scsi (for just Sun JNI) } Use 'prtconf -vp' to get Ivory WWN (4981437)
