Dear Konrad,

Thank you very much for your reply,

This command would help finding out the SAS addresses of any devices 
connected to the initiator, which would then work perfectly.

Unfortunately, I am working on a target configuration and trying to get 
the SAS address from a connected host.

The configuration would look like that:

Host(Initiator) <FC Link> - <FC Link> Target - <SAS> - <SAS> Disks.

I am trying to find the  WWN from the actual initiator host's FC card 
instead, from the Target.

Would you have more infos on how to do this?

Thanks in advance,
