The machine on which the calibration db servers were running is unreachable, so the servers have automatically failed over to the back up node. No action is required from the sam shifter, although you might like to check that all the servers did actually start up on the new node by checking the db server status at http://d0db.fnal.gov/sam_admin/cgi/nameService?show=dbserver .
