"How to find HBA card / WWN in Solaris OS aka Unix Flavours"
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
root@ sunserver:/root# scli -i egrep “Node NamePort Name”
root@ sunserver:/root# prtconf -vp grep -i wwn
root@ sunserver:/root# prtpicl -v grep wwn
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
