HPUX locating WWPN

Locating the WWPN for an HP-UX host

Complete this task to locate the WWPN for a Hewlett-Packard Server host.

   1. Go to the root directory of your HP-UX host.
   2. Type ioscan -fnC fc| more for information on the fibre-channel adapters installed on the host.
      The following is example output:

      fc 0 0/2/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td0
      fc 1 0/4/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td1
      fc 2 0/6/2/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td2

   3. Look under the description for the Fibre Channel Mass Storage adapter.

      For example, look for the device path name /dev/td1.
   4. Type: fcmsutil /dev/td1 | grep world where /dev/td1 is the path.
      The following is example output:

      # fcmsutil /dev/td1 | grep World
                  N_Port Node World Wide Name = 0x50060b000024b139
                  N_Port Port World Wide Name = 0x50060b000024b138
      (root@hpmain)/home/root# fcmsutil /dev/td0 | grep World
                  N_Port Node World Wide Name = 0x50060b000023a521
                  N_Port Port World Wide Name = 0x50060b000023a520
      (root@hpmain)/home/root# fcmsutil /dev/td2 | grep World
                  N_Port Node World Wide Name = 0x50060b0000253a8f
                  N_Port Port World Wide Name = 0x50060b0000253a8e
      (root@hpmain)/home/root#
