Symptoms

  • Asynchronous replication session is created but no transfer is in progress.
  • Replication Connection is green and verified, no errors.
  • Network is good, no bottlenecks or hardware issues.

Cause

  • Dell Unity™ Family Security Configuration Guide mentions that the port 8888 is required for an Asynchronous replication. Ports 443/5085 are used for management or for interconnects between arrays and the data transfer is through 8888. If the system detects a valid management path it shows the connection as healthy even though the data path (8888) is blocked.

Resolution

  • Make sure port 8888 is allowed between Asynchronous replication interfaces/IPs.
