Thanks a million! That did the trick.

Since my p0 was OK I ran (from the shell) 
	vinum init -v -w mirrored.p1

This produced several minutes of disk activity and the curser waited until the
command finished. vinum list showed the plex up but the subsidk still faulty, so
I ran

	vinum start mirrored.p1.s0

The also produced several minutes of disk activity, but the process ran in the
background after displaying "Reviving mirrored.p1.s0 in the background." From
time to time I ran vinum list and where it used to display "faulty" it now read
State: R 1% with the percentage increasing each time I ran the command.
Eventually the background process reported that mirrored.p1.s0 is up. And it is.
