You can see multipathing at ESXi level not at virtual machine level.
For RDM you can check inside the VM using
I am using RDM only. "multipath -l" lists only one path on VM. Is there anything that I might have missed during configuration ?
Although at ESXi level, multiple paths can be seen.
What i think is virtual machine sees a RDM as a normal disk presented by the Host, all the Fibre Channel techniques are applied at ESXi level, hence it provides a abstraction and you virtual machine is not exposed to underlying complex mechanism.
