You will want to reboot, and attach the other side of the mirror. The example below shows how attach your one way mirror to your metadevice. Note that you do not need to specify "d10 1 1 c5t0d0s0" if you have added this information to the md.tab Use the '-f' switch when the filesystem on that slice is currently mounted. Here I am initializing each side of the mirror. In the example below you are initializing your one way mirror. Not sure if you need the -f option on the second db, but it does not seem to cause any issues. In the example above you are creating 3 metadbs on the mirror disk. The normal standard that I follow, has me creating them on slice 3. Make sure that you create them on the correct slice. In the example below the metadevice d0 has two submirrors, d10 and d20. The file /etc/md.tab is basically a map file where you define your metadevices and the physical devices that they represent. Then switch to the other disk and label the other disk with the saved Name to save off you partition table to disk.
