Heartbeat comes with a nice script to make this easy:

/etc/ha.d/resource.d/drbddisk < drbd resource >  < start | stop >

You can use this even if Heartbeat isn't running, and it's the script  
Heartbeat will use, so if you're testing to make sure Heartbeat will  
work, I recommend using it to test. If you want to be gentle, stop  
the resource on the first node and then start it on the second. If  
you want to be more paranoid, pull the plug on the first node instead  
of stopping the resource, and verify everything is still correct.
