I'm not aware that yast can repair raids :-?

Here are my notes on mdadm (change device names as appropriate for your 
setup):

State of things:

        mdadm --detail /dev/md0

Simulate a failure:

        mdadm --manage --set-faulty /dev/md0 /dev/hdb11

Remove a disk:

        mdadm /dev/md0 -r /dev/hdb11

Add a disk:

        mdadm /dev/md0 -a /dev/hdb11


Usually adding the disk is enough to trigger the rebuild process. But 
first, try to learn what happened. By the way, there is a daemon that 
could have emailed you the problem.
