World Wide Name (WWN) are unique 8 byte (64-bit) identifiers in SCSI or fibre channel similar to that of MAC Addresses on a Network Interface Card (NIC).
Talking about the WWN names, there are also
World Wide port Name (WWpN), a WWN assigned to a port on a Fabric which is what you would be looking for most of the time.
World Wide node Name (WWnN), a WWN assigned to a node/device on a Fibre Channel fabric.
To find the WWN numbers of your HBA card in Sun Solaris, you can use one the following procedures
Using fcinfo (Solaris 10 only)
This is probably the easiest way to find the WWN numbers on your HBA card. Here you can see the HBA Port WWN (WWpN) and the Node WWN (WWnN) of the two ports on the installed Qlogic HAB card.
This is also useful in finding the Model number, Firmwar version FCode, supported and current speeds and the port status of the HBA card/port.
root@ sunserver:/root# fcinfo hba-port | grep WWN
HBA Port WWN: 2100001b32xxxxxx
Node WWN: 2000001b32xxxxxx
HBA Port WWN: 2101001b32yyyyyy
Node WWN: 2001001b32yyyyyy
For detailed info including Make & model number, Firmware, Fcode and current status and supported/current speeds then
root@ sunserver:/root# fcinfo hba-port
HBA Port WWN: 2100001b32xxxxxx
OS Device Name: /dev/cfg/c2

Using scli
root@ sunserver:/root# scli -i | egrep “Node Name|Port Name”
Node Name : 20-00-00-1B-32-XX-XX-XX
Port Name : 21-00-00-1B-32-XX-XX-XX
Node Name : 20-01-00-1B-32-YY-YY-YY
Port Name : 21-01-00-1B-32-YY-YY-YY
For more detailed info on the HBA Cards run as follows: Similar to fcinfo but also provides Model Name and serial number.
root@ sunserver:/root# scli -i

Using prtconf
root@ sunserver:/root# prtconf -vp | grep -i wwn
port-wwn: 2100001b.32xxxxxx
node-wwn: 2000001b.32xxxxxx
port-wwn: 2101001b.32yyyyyy
node-wwn: 2001001b.32yyyyyy
Using prtpicl
root@ sunserver:/root# prtpicl -v | grep wwn
:node-wwn 20 00 00 1b 32 xx xx xx
:port-wwn 21 00 00 1b 32 xx xx xx
:node-wwn 20 01 00 1b 32 yy yy yy
:port-wwn 21 01 00 1b 32 yy yy yy
Using luxadm
Run the following command to obtain the physical path to the HBA Ports
root@ sunserver:/root$ luxadm -e port
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl CONNECTED
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0,1/fp@0,0:devctl NOT CONNECTED
With the physical path obtained from the above command, we can trace the WWN numbers as follows. here I use the physical path to the one that is connected:
root@ sunserver:/root$ luxadm -e dump_map /devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl
Pos Port_ID Hard_Addr Port WWN Node WWN Type
0 123456 0 1111111111111111 2222222222222222 0×0 (Disk device)
1 789123 0 1111111111111111 2222222222222222 0×0 (Disk device)
2 453789 0 2100001b32xxxxxx 2000001b32xxxxxx 0x1f (Unknown Type,Host Bus Adapter)
Hope this helps. If you know of any more way then please feel free to post it to the comments and I shall amend it to the article.
