When you run a replication job you see rehashing disk(s) when the job runs and the job does not seem to progress.
This can happen if vRanger sees the replica VM as a preseeded VM.
If you are trying to run a first pass replication and not using a preseeded VM than the replica VM should be deleted and the replication job should be ran again with no replica VM being present at the DR site.
If you are trying to run a first pass replication and you are using a preseeded VM please see KB SOL90355 for additional information at the following link https://support.quest.com/Search/SolutionDetail.aspx?id=SOL90355.
