Time to time, your pool server goes out of service for maintenance or some other odd reasons. When you are not around there is no way to know and you don’t want to be around your rig all day long to change any settings. That’s is not passive income!!!
Well, here is the solution. Failover only command in batch file.
–failover-only -o stratum+tcp://NEW POOL URL:3333 -u user -p password
*There are two dash lines in front of failver-only. – – (Type two dash lines without space. I had to put space for you to see in this blog.)
Add this to the batch file that you are currently running. Whenever your pool server is down, it will automatically log in to other pool and start mining there until you restart your batch file to go back to your original pool. Yeah.. there isn’t cgminer setting that can detect server back in service and log back into original server again. At least that’s what I know so far. =p

It is confirmed that after 1st server is down, failover command automatically logs in to 2nd server then once 1st server is back up, failover command returns the log back in to 1st server.
Also, you can have multiple server listed with failover command.
