You run the startup script with the option '-migrate' on the primary
host. This will shut down the master on the backup host and restart
the master on the primary.

As an automatic alternative you can write the name of the primary host
into $SGE_ROOT/$SGE_CELL/common/primary_qmaster. Then a regular startup
of the primary host will automatically migrate the service back.
