Time for the third post in the AdminSeries – how to shutdown the data nodes. This post follows the previous two: How to Shutdown the Database(s) and How to Shutdown the Storage. Before you read much further, go check them out first.
With that out the way, let’s get started.
In ExaOperation, head over to the Nodes tab. It should look something like this:
In this shot, you can see the State of the nodes is Running and they are Powered On.
Next up, select the checkboxes next to the Nodes that you want to shutdown. From the Actions drop down, select Shutdown, and then the button Execute.
It may take some time for the nodes to shutdown, as with all things ExaOperation, be patient and wait for it. You can refresh the page and watch for the node state to change. Sometimes the Nodes change state, one at a time, so you may be waiting for some nodes.
Eventually your page should look like this. All of the Nodes will have the state of Installed, and Power Off. Your nodes are now Shutdown.
That brings us to the end of How to Shutdown Data Nodes. Next up, we’ll be looking at How to Restart the licence node.
