Maintaining Nodes
Node Templates have four phases: provisioning, configuration, deployment, and maintenance. You can apply the Maintenance tasks specified in a node’s template by taking the node offline, then using the Maintain action on the node. For example, you can use the Post Install Command task to install applications on compute nodes, and you can use the Apply Updates task to apply software updates.
Note
You can also use clusrun commands to run a command-line command in parallel across a set of nodes in the cluster. You cannot use clusrun to install a service pack for Microsoft HPC Pack because such an update stops the services for clusrun itself. For more information, see View and Run Clusrun Commands.
The topics in this section describe how to run maintenance tasks on compute nodes and how to apply software updates.
