There are times when a system may require maintenance or be taken down for some specific reason. During these times you will want to disable the node installed on that system. Disabling the node allows the cluster to manage the jobs based on the remaining nodes that are available for work.
Once any work has been done on the system and you want to bring the node back into use, you need to enable the node so that the cluster knows the node is available and ready for work. Once the node is enabled, the cluster will assign the jobs waiting to be processed.
As nodes are an important part of the job processing, knowing about the nodes is vital so that you can ensure they are functioning properly and that the cluster has enough nodes to process jobs.

A computer can also be queried to see if there is a node install on it.
