fdisk

Let's assume that we already have a primary physical drive in our system (HDD or SDD), and have added a second drive to our box, which we need to partition and mount automatically on boot.

Here's how to that:

Let's see what physical drives we have installed in our server:

ls /dev/sd*

Since this is our 2nd drive, you should see /dev/sdb.

Example:

/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3  /dev/sdb

Let see the currently mounted drives and partition layout:

lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

Here's a full list of all available lsblk options:
