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.
In the management GUI,
select . On the System -- Overview page,
select the directional arrow for the enclosure that contains the node
canister that you are removing. On the Enclosure Details page, right-click the node canister in the rear view of the system
graphic and select Remove from the Actions menu.Note: When
the configuration node is removed from the system, the SSH connection
to the system closes.
- Open a web browser and type http://service_assistant_ip in the address field.
The 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 .
