Use the vSphere CLI to list all multipathing modules loaded into the system. Multipathing modules manage physical paths that connect your host with storage.

To list all multipathing modules, run the following command:

vicfg-mpath --server <server> --list-plugins,

where <server> is your vSphere CLI administration server. You might be prompted for a user name and password.

At a minimum, this command returns the NMP module. If any third-party MPPs have been loaded, they are listed as well.

MPP_1
MPP_2
MPP_3
MASK_PATH
NMP
