How to identify HBA and WWN for Citrix Hypervisor

Working on a project for a client, I accidentally found out that Citrix not done the greatest job documenting how to get HBA and WWN informations for Citrix Hypervisor (Aka XenServer).

Citrix have writing this article, https://support.citrix.com/article/CTX217604 but there is a much simpler way.

Connect first to your host either with XenCenter or putty, then run command:

To find the HBA cards installed on your system use :

lspci -nn | grep -i hba

Now you should get your HBA:

Check the available HBA ports:

ls -l /sys/class/fc_host

To find the state of HBA ports (online/offline) :

more /sys/class/fc_host/host?/port_state

To find the WWN numbers of the above ports :

more /sys/class/fc_host/host?/port_name
