Install ansible on a single host, make an inventory file of all of your linux hosts.

Use ansible to run an ad-hoc command on all hosts in parallel to list the WWNs using the article I linked you above as a reference on where to find said WWNs.

eg: ansible all -i linux.inventory -m shell -a " cat /sys/class/fc_host/host*/port_name"

The fabric switch will also list any storage devices on the fabric.

I used to do the same thing with my windows hosts in powershell.

I ran a separate script to list all of the wwn to compare the lists with. It was not hard to do over ssh.

I also grabbed the list of hosts on my storage devices.

Usually though the storage cli or powershell interface
