Adding a Host to a new HA node
If an HA node fails, when the HA node is running again, it will synchronize with the other HA nodes. However, if a host
requires a connection to an HA node in the cluster and cannot wait for that node to restart, you can manually move the
host to another node. To move the hosts:
1. On the DSM, click
High Availability
.
2. Click on the Name of the node to which you want to move the Agent(s).
3. Click
Host Assignment
.
4. Click
Add
. The Details page opens and displays all of the Agents connected to the HA cluster.

5. Select and click
OK
for nodes that you want to move to your current node. The DSM moves the selected Agent
host from the previous HA node to the current HA node.
Note
You can assign both unassigned hosts and hosts currently assigned to other nodes. DSM will move those
nodes from the previous node to the current node.
6. Once the original HA node is up and running, you can reassign the VTE Agent(s) back to the original node, if
desired.
