Requirements
There are a few requirements that need to be met in order to utilize the replication manager with vSphere Plugin 5.2.0 or higher.
- To utilize replication workflows between two vCenters, they must be in Enhanced Linked Mode
-
The replication workflows will not failover virtual machines between two unlinked vCenters
-
- When using the replication workflows with two (or more) linked vCenters, replication groups must not be shared between vCenters.
- It is not supported to use linked vCenters that are registered with the same array's VASA providers.
-
- A single plugin instance must be able to communicate with both vCenters in order to be able to get a list of the virtual machines in the replication groups, perform virtual machine specific tasks and track tasks/requests; a single plugin instance is not able to communicate with multiple unlinked vCenters.
- When using the replication workflows with one vCenter, that vCenter must be connected to both arrays that are replicating and access to vVol Datastores on both arrays.
Note:
This KB will not be going into an in depth explanation of the vVols APIs that are leveraged by the replication manager.
