Hmm... interesting that what you did even worked... I'd have
thought /dev/sd3a would have still been held 'open' by the RAID set,
and that the hot-add would have failed.

If you're using the autoconfigure stuff (which you should be) then a
simple reboot should fix things up. (it will write out the correct 
component label for sd3a as part of unconfiguring /dev/raid1 )
