The Switch Health Analysis window displays any problems affecting the selected switches.

Analyzing End-to-End Connectivity

Select Tools > End to End Connectivity option from Fabric Manager to determine connectivity and
routes among devices with the switch fabric. The connectivity tool checks to see that every pair of end
devices in an active zone can talk to each other, using a Ping test and by determining if they are in the
same VSAN. This option uses versions of the ping and traceroute commands modified for Fibre
Channel networks.
The End to End Connectivity Analysis window displays the selected end points with the switch to which
each is attached, and the source and target ports used to connect it.
The output shows all the requests which have failed. The possible descriptions are:

the port during discovery.
Both devices are on the same switch—The devices are not redundantly connected.
No paths exist.
Only one unique path exists.
