If by "failover" you mean "start sending I/O over the wire to server B" 
then yes if you have "on-io-error: detach" set. DRBD on server A should 
pick up the I/O error passed to it by the SCSI driver when the disk 
fails and will go into diskless mode.

If you want to actually failover services etc., you need Heartbeat.
