Veritas Volume Replicator (VVR) Status Script

The Veritas Volume Replicator (VVR) Option provides organizations with a foundation for continuous data replication, enabling rapid and reliable recovery of critical applications at remote recovery sites. As an option to Veritas Storage Foundation by Symantec, Volume Replicator enables efficient replication of data over IP networks, giving organizations an extremely flexible, high-performance alternative to traditional array-based replication architectures. This flexibility lets organizations choose virtually any combination of storage devices on any major operating system, providing a consistent, easy-to-manage high availability/ disaster recovery solution throughout the data center.
 
In the event the connection between the replication nodes goes down temporary. VVR will store all the transactions in an SRL volume. When connection is restored. VVR will try to sync up all rlinks and flush the SRL.
 
One of the things that I like to know is how much data is remaining to be sent over. Having to enter multiple commands to check on all of my rlinks and doing the math just to find how much data is left. Doing this every time can become cumbersome.
 
So, for those who uses VVR and run into this issue, below is a script you can use to check the replication status.
 
Hope this helps!
