Issues during online migration of coordination points
During online migration of coordination points using the vxfenswap utility, the operation is automatically rolled back if a failure is encountered during validation of coordination points from any of the cluster nodes.
Validation failure of the new set of coordination points can occur in the following circumstances:
The /etc/vxfenmode.test file is not updated on all the SF Oracle RAC cluster nodes, because new coordination points on the node were being picked up from an old /etc/vxfenmode.test file. The /etc/vxfenmode.test file must be updated with the current details. If the /etc/vxfenmode.test file is not present, vxfenswap copies configuration for new coordination points from the /etc/vxfenmode file.
The coordination points listed in the /etc/vxfenmode file on the different SF Oracle RAC cluster nodes are not the same. If different coordination points are listed in the /etc/vxfenmode file on the cluster nodes, then the operation fails due to failure during the coordination point snapshot check.
There is no network connectivity from one or more SF Oracle RAC cluster nodes to the CP server(s).
Cluster, nodes, or users for the SF Oracle RAC cluster nodes have not been added on the new CP servers, thereby causing authorization failure.
