1. Check any network components that are capable of packet filtering (such as firewalls) to determine if replication packets are being dropped because the packet size exceeds a limit that has been specified by the network component. In many cases, large UDP packets are blocked by default.
2. Verify that the firewall is not blocking ports 4145 (UDP), 2148 (TCP/UDP), 8199 (TCP) or 8989 (TCP)
In some cases, the operation may eventually succeed despite the error message. This can happen if VVR is still waiting for read or write requests or other commands to complete.
3. Restart the Veritas Storage Agent service.
Warning: Restarting the Veritas Storage Agent service in a clustered environment may cause Volume Manager Disk Group (VMDG) resources to fault.
- If Veritas Clustering (VCS) is present, freeze any cluster service groups that contain VMDG resources before restarting the Veritas Enterprise Administrator service
- If Microsoft Clustering (MSCS) is present, move any cluster resource groups that contain VMDG resources to another node before restarting the Veritas Storage Agent service
4. Decrease the replication packet size to 1300 bytes
5. Delete and recreate the replicated data set (RDS)
RecommendationWhen creating an RDS using the wizard, set the packet size to 1KB or 1400 bytes (default) or lower
