How to find HBA WWN in HP Unix

in HPUX we have inbuilt  utilities/commands to find  HBA details. The easy way to find HBA details is by using "fcmsutil" command.

1.fcmsutil - Fibre Channel Mass Storage Utility Command for Fibre Channel Host Bus Adapters.

Usage:-
/opt/fcms/bin/fcmsutil device_file [options]


The device_file specifies the Fibre Channel device special file associated with the Fibre Channel HBA port. The device file has the format /dev/FC_driverX, where X is the instance number of the Fibre Channel HBA port, as reported by the ioscan output.

2.ioscan - scan the I/O system
Usage:-
/usr/sbin/ioscan [-N] [-k-u] [-e] [-d driver -C class] [-I instance][-H hw_path] [-l] [-A] [ -f[-n]-F[-F][-n] ] [devfile]

the main options associated with this usage are
-C class Restrict the output listing to those devices belonging to the specified class.

-f Generate a full listing, displaying the module's class, instance number, hardware path, driver,software state, hardware type, and a brief description.

-n List device file names in the output. Only special files in the /dev directory and its subdirectories are listed. Must be used with either the -f or the -F option.

 
The process to find out HBA details in an HPUX machine is as follows:

1, Use ioscan command to find the FC device files associated with that server.
# ioscan -fnC fc
2, Use fcmsutil command to find the HBA details associated with GC devices.
# fcmsutil /dev/fcd4

Example:-
[root@hpux:/root]


# ioscan -fnC fc
