The idea behind fence_manual is that you need to go and manually fence the failed machine somehow when you see that message. That means doing yourself what one of the normal fencing agents would otherwise do, e.g. power it off, disable its SAN connection. After you've done this, you run fence_ack_manual to tell the system that the failed node has been properly fenced (by you). If you reset the failed node, you just need to make sure the power is off before doing the ack command; you don't need to wait for it to be up and running again. If you reset the failed node and it comes back up and rejoins the cluster before you happen to run the fence_ack_manual command, then the fence_manual agent that's waiting on the non-failed node will recognize this and effectively do the fence_ack_manual step for you since it knows the failed node has been rebooted if it rejoins the cluster.
