metadevices
Configure metadevices with metainit
– metainit –f d101 1 1 c0t0d0s0
– metainit –f d100 -m d101
– metainit –f d102 1 1 c0t1d0s0
– create as many metadevices as you need

Before you are going to connect the mirror you need to reboot, so the system can boot from the new boot device.
Make the system ready for booting with metaroot
– metaroot d100
