Symptomen



Scenario 1: When trying to create/verify a Replication Connection, and the Connection Mode is "Both", it does not complete.
Scenario 2: A replication connection between two Unity systems with connection mode as "Both" was created but cannot be verified. Its 'health status' is degraded with no 'remote interface'.  
 

Oorzaak

Scenario 1: In this particular example, the Replication Connection is not completing because there are no existing Asynchronous IP Interfaces. When Connection Mode "Both" is selected, there must exist Synchronous IP Interfaces (Sync Replication Management Port) and Asynchronous IP Interfaces (Ethernet Port x) on the Source and Target Unity systems.

Scenario 2: There are no fibre channel (FC) ports configured on these Unity systems.

Oplossing

Resolution:

Scenario 1: Under Unisphere > Data Protection > Replication > Interfaces, create an Ethernet Port x replication interface pair for the local SPA and SPB, and repeat on the target system. Once the interfaces are created, retry the create Replication Connection task.

Optionally, select only Synchronous for the 'Connection Mode' when creating the Synchronous Replication Connection.

Scenario 2: Synchronous replication needs fibre connectivity between source and destination Unity systems, hence only asynchronous 'connection mode' can be setup and not both (synchronous and asynchronous). Otherwise, configure FC ports on both SPA and SPB for each Unity system.

Extra informatie

Scenario 1: When trying to create/verify a Replication Connection, and the Connection Mode is "Both", it does not complete with the following:  
Failed: The remote system is registered but local interconnects validate has failed. The time skew between the local and remote systems may be more than 10 minutes. Fix the time skew and run verify operation on the remote system to resolve the issue. For more information, view alerts related to the remote system connections. (Error Code:0x6500128)
Rollback Result: Task was rolled back and marked as failed. This is because some tasks failed or SP rebooted during task execution. (Error Code:0x100a)

Subsequently, if 'Verify and Update' is run, it does not complete with:  
Failed: For a replication connection that supports both synchronous and asynchronous replication sessions, ensure that you have at least one interface each configured on the management and data ports of each SP. (Error Code:0x650016d)
 
Scenario 2: A replication connection between two Unity systems with connection mode as "Both" was created but cannot be verified. It's 'Health status' is degraded with no 'Remote Interface'.
