Viswanadhan,

To get the WWN on the HBAs use the command fcmsutil /dev/fclp0 and again for /dev/fclp1

Re: How get WWN for disk.

Bonjour,

assuming you are working with HP-UX 11iv3, you have many tools. Some examples :

ioscan -m lun -C disk : you will see all the path to a disk, storage array controlers's WWN, LU number

scsimgr -p get_attr -D /dev/rdisk/disk652 -a wwid : WWN of the LU itself

fcmsutil /dev/fcd0 : will show the WWN of the hba, on which switch and port it is connected.

And many, many other options. RTFM, man and test by yourself.

HTH
