Failback without updating tracks on R1
We want to failover from R1 to R2. I see if i use the failover command the DMX then keeps a record of the track changes. Is there a way when we failback that we can choose not to update the R1 with any of the track changes - i.e. so effectively there will be no change to the R1 when we bring it back up.

First if you know that this going to happen, it would be better to run a "symrdf split" command instead of a "symrdf failover" command. Changes are still tracked (both ways) but it's easier to recover. Once you've decided to re-syncronize your pairs, you would issue one of the following commands:
symrdf -g group establish <--- This command will take data from the R1 device and overwrite the data on the R2
or
symrdf -g group restore <--- This command will take data from the R2 device and overwrite the data on the R1
You need to be VERY CAREFUL here because choosing the wrong commands will cause data loss.
If you do run the 'symrdf -g group failover' command and wanted to just drop the changes that were made to the R2, it's a two step process.
First, issue a 'symrdf -g group rw_enable r1 -force' command. This will put the pair into a SPLIT state.
Now that the pair is SPLIT, you can issue a 'symrdf -g group establish' command to have the R1 device overwrite the changes on the R2.
Hope this helps.
