How to find HBA WWN (World Wide Name) in Sun Solaris

To find the WWN numbers of your HBA card in Sun Solaris, you can use one the following procedures

For Solaris 8 ,9 and 10, to find the link status of the HBA's run the following command.

[10:20:39] root@ecpdb[2]# luxadm -e port

Found path to 3 HBA ports

/devices/pci@8,600000/SUNW,qlc@1/fp@0,0:devctl                     CONNECTED

/devices/pci@8,600000/SUNW,qlc@2/fp@0,0:devctl                     CONNECTED

/devices/pci@9,600000/SUNW,qlc@2/fp@0,0:devctl                     CONNECTED

note down the connected HBA device files

To find the WWN associated with CONNECTED HBA's run the following command.

[10:20:39] root@ecpdb[4]# luxadm -e dump_map /devices/pci@8,600000/SUNW,qlc@1/fp@0,0:devctl

The WWN's which are mentioned by type "Host Bus Adapter" represents WWN of connected HBA's.

prtconf  will also display WWN of the connected HBAs

[10:20:39] root@ecpdb[10]# prtconf -vp | grep wwn
