After all the other nodes are updated on the system,
you can update the configuration node.
To update the configuration node, follow these steps:
- Ensure that all hosts have all paths available to volumes
that are mapped to those hosts. If not, wait up to 30 minutes and
repeat this check. If some paths are still unavailable, investigate
and resolve these connection problems before you continue the system code update.
- Record the name of the configuration
node on the system before you upgrade the configuration node. To view
the node name in the management GUI, select .
- In the management GUI, check that there are no incomplete volume synchronization tasks
in progress. Click Running Tasks.
- Remove the configuration node from the system.
select . Right-click the canister
and select Remove.Note: When
the configuration node is removed from the system, the SSH connection

service assistant IP address is the IP address for the service assistant
on the node that was deleted.
- On the service assistant home page,
click Exit service state and press Go.
Use the management GUI to add the node to the system. The node is then updated before it
joins the system and it remains in the adding state for some time.The node is automatically added to the system. Because the process
of adding the node automatically updates the code on the
node, it takes some time before the node is fully online.This
action automatically updates the code on this last node,
which was the configuration node.

After the configuration
node is updated and added back to the system, rename the node canister
to the name it had before it was removed and updated. In the management GUI, select .
