Locating the WWPN for an HP-UX host

To attach your DS8000® to a Hewlett Packard Enterprise (HPE) server that is running the HP-UX operating system, you must locate the worldwide port name (WWPN) for the host.

To locate the WWPN, complete the following steps:

1. Go to the root directory of your HP-UX host.
2. Enter ioscan -fnC fc| more for information about the Fibre Channel adapters that are installed on the host.
   The following example shows the output of the ioscan command:

   
   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. Enter fcmsutil /dev/td1 | grep World where /dev/td1 is the path.
   The following example shows the output of the fcmsutil:

   (root@hpmain)/home/root# 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#
