A local SC Series storage array is replicating to a remote SC Series storage array. A problem occurs on the local array which causes you to failover to the remote array. Once the issue is controlled, you need to failback to the local array. However, when you attempt to failback to the local array, no volumes are available to failback.
What is the reason for this Issue?

• A.Remote SC Series array is still running
• B.Replication restore points need to be validated
