OVH SSD+SATA PROXMOX

[sede]

Hello to all i'm a new one around here and my first instalation with proxmox.
Just for a start i've got a really huge need for a clear help because i'm not seeing how to solve it.

I've got proxmox installed in the ssd disk, and when access proxmox i cannot see the sata disk . How can allocate ( in case thats the proper name) of the 1.8 TB SATA to the proxmox in order to use it has diskspace for the lvm's ?
