A quick reboot will likely restart (start) the RAID sync or you can try
adding the slice back in as follows:
# Look at each partition
lsraid -a /dev/md0
# Add new disk back into the array
raidhotadd /dev/md0 /dev/sda1
This presumes the lsraid shows it is not in the array any longer..
Not an expert here, just passing on what I know..
