View how much data has replicated VNXe


I was wondering if there is a way to see how much data is replicated as part of a replication session. We have a VNXe at our production site and another one at a DR site and we perform overnight replications of a LUN to the DR site using replication manager 5.4.2. Is there a way to see how much data in terms of GB/MB has actually replicated?

We are able to get a rough idea by calculating the transfer rate over the line using the available bandwidth and the time taken for the replication to take place but wanted a more definitive way of finding this out. Is there a tool that can be used for this or is this information buried somewhere in the logs etc?

Hi Chris,

You can do the following

Click System > System Replications to display a list of replication


Select a replication session from the list and click Details.

The Session Details Summary pane displays the following information:

Status of the replication session.

Type of storage resource associated with the replication session.

Name and current state of the replication session.

Status of the network, source storage resource, and destination storage

resource associated with the replication session.

Synchronization mode for the replication session. If automatic, the

recovery point objective is also displayed.

Can you please provide the command output of nas_cel -l?

Please delete the host name and ip address from the output.

If you want to contact me directly you can contact on nv.rohanraj@gmail.comor

Thanks for the reply. The replication session shows as fine although the synchronization shows as manual. Will post the results of nas_cel -l when i get a chance to do this.

Just to confirm, it is a generic iSCSI lun hosting basic file data and we are looking for a way to see how much data has changed and subsequently been replicated.

Hi Chris,

From Replication Manager end we can have a look into the job history which shows the percent of data that is synced during the replication. But if you are looking in terms of a particular value of data copied then I am not sure. As far as I know even if we try to look into the amount of data copied by logging into the VNXe CLI we can only see the state of the replication and not the amount of data copied to the target VNXe. Please correct me if I am wrong.
