Preparing for maintenance

Context

One of the most helpful features of Viewpoint for Moab HPC Suite is that it allows you to create maintenance reservations on particular nodes. When you create these reservations, Moab evacuates the current workload off of the node so that you can perform your maintenance. These steps explain how to create a maintenance reservation in Viewpoint.

To prepare your system for maintenance

  1. Navigate to the New Reservation page (Cluster > New Reservation). For details, see Fields: New Reservation.
  2. (Optional) Specify a name for your maintenance reservation.
  3. Under Advanced Settings, do the following:
    1. (Optional) Specify a text description of the maintenance reservation.
    2. Clear the Dedicated resource specification option.
    3. Select the Evacuate workload specification option.
  4. (Optional) Use the Access Controls to grant access to the reservation to specific groups, users, or accounts.
  5. Use the Scheduling options to specify the start and end time of the maintenance window.
  6. Under Resources, specify the nodes you want Moab to create the maintenance reservation on.

    7. You must specify the nodes using the Select Nodes option. The Node Count option is disabled when you choose to evacuate workload from the node.

  7. Save the reservation.
