What exactly is the question? If all you are interested in is some basic info about your hard drive, just run
Code:

fdisk -l
Note that's a lowercase "L". Good luck with it

Sorry - I'm still confused by "WWN world wide number". Do you mean the serial number, or the manufacturer's part number, or something else? My apologies but I am just not familiar with this term (when I hear "world wide number" I'm thinking "IP address"), but hopefully others have.

I'm also not sure exactly what you want, but if you need some info about the disk you could try hdparm:
Code:

hdparm -I /dev/sda

i am only familiar with wwn numbers in the context of fibre networks. and obviously fibre switches, sans, fibre cards etc.

maybe you have your own SAN.....

:-)

from hpux:

fcmsutil /dev/td1

Vendor ID is = 0x00103c
Device ID is = 0x001029

PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x00128c
Topology = PTTOPT_FABRIC
Link Speed = 2Gb
Local N_Port_id is = 0x010900
N_Port Node World Wide Name = 0x50060b0000240cef
