WWN on HP-UX: How To?

Bookmark and Share


Below are the commands used to identify WWNs on HP-UX,
#ioscan -fnC fc
Above CLI will list all HBAs (FC port) detected by HP-UX. Lets say from the output we determine one of the FCs as /dev/fcd0
#fcmutil /dev/fcd0 
This CLI will display all information about /dev/fcd0. If we want specific information about WWN then we can easily grep the output of above CLI as below,
#fcmutil /dev/fcd0 | grep -i WWN
