add Physical  driver to a server

Hi,

Could you please describe the issue more detailed?

Is the server virtual or physical?

Did you try to use Add-PhysicalDisk command?

This command adds a physical disk to the specified storage pool or manually assigns a physical disk to a specific virtual disk.
