Multipath is just above the OS layer and below the Virtualization (Proxmox) layer. You should google something like "MD32xxi dell multipath guide linux" - the very first hit seems to be very promising https://i.dell.com/sites/content/bu...t-md32x0-md32x0i-linux-dm-installation-en.pdf

Follow the vendor guide for best results
