How do I add a new hard disk to LVM?

Hello,
The LVM configuration is as follows:
Code:# df
Filesystem 1K-blocks Used Available Use% Mounted on
udev 1967448 0 1967448 0% /dev
tmpfs 398368 556 397812 1% /run
/dev/mapper/Docker--vg-root 17172304 8163408 8111260 51% /

tmpfs 398368 0 398368 0% /run/user/1000I added a new hard drive (xvdb) to the system:
Code:# /sbin/fdisk --list
Disk /dev/xvdb: 50 GiB, 53687091200 bytes, 104857600 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes
Ignoring extra data in partition table 5.

...How can I use it as another partition?

Thank you.
