Hyper-V 2012 Failover

Today I had a Primary VM fail and simply put it will not start back up we are running replica to an external site and I have had to preform the failover procedure to get the server back up and running.

My question is what is the correct process now to get the server back running in the correct Host taking into account the primary copy of this server is corrupt, as this is not a normal failover where a general site has gone down to a power outage I would like to know the steps to successfully replicate the server back to the original way it was.


Any help will be greatly appreciated

Reverse Replication, so the good copy is replicated back over the corrupted version.

or power-up the Replicated copy on the DR host.

I have powered up the replica version of the server on the external Site (DR host). Will reverse replication fix the corrupted issues with the primary server?

it will replicate the changes back from the current working server to the old server.

So in effect you will get a copy of the current server on the non-DR host.

Ok in relation to the issue described below what will be the most efficient way of copying back over the data? will using the existing copy fix the errors as well or will I need to delete the old corrupt VM and send over the copy from scratch.

Thanks

Personally, we would break the existing replication, delete the existing broken version, setup new replication job to replicate from working to create new  VM.

Hanccocka,

Thanks very much for the advice, in the end i replicated the server back using reverse replication and then performed a planned failover.

this brought the server back up and in working order.

Thanks
