Use the esxcli command to list all multipathing modules loaded into the system. Multipathing modules manage physical paths that connect your host with storage. The modules include VMware native NMP and HPP, and any third-party MPPs.


Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.


To list multipathing modules, run the following command:
esxcli storage core plugin list --plugin-class=MP


This command typically shows the NMP and, if loaded, the HPP and the MASK_PATH module. If any third-party MPPs have been loaded, they are listed as well.

Plugin name  Plugin class
-----------  ------------
NMP          MP

For more information about the command, see the vSphere Command-Line Interface Concepts and Examples and vSphere Command-Line Interface Reference documentation.
