Mounting 2nd hard drive to proxmox

Hi, I just have a question in regards to proxmox. Is there a way to mount a whole drive and access it as normal drives? I just want to use the previous qcow2 files i have there for my vm drives. I tried qm import but the qcow2 file is at 500gb and my local-lvm is just 150gb. Also tried creating a folder and mounting it there but still didn’t work. Any help would be very much appreciated.
