FreeBSD Find Out All Installed Hard Disk Size Information

How do I find out all installed hard disk drive names under a FreeBSD operating system without rebooting the server? How do I use the equivalent of fdisk -l in Linux, with FreeBSD to list all hard disks drives? How can I find hard disk size in FreeBSD?
