Look in the device path for the fiber-channel adapters. In a JS23/JS43 there are
always dual port host bus adapters used, represented by the following two
entries:
Port 1 /pci@800000020000204/fibre-channel@0
Port 2 /pci@800000020000204/fibre-channel@0,1
This information will be required in the next steps to change the topology and the
link speed of the host bus adapter.
