Common Change Control Rollback

BC Project: FY06-12
Date of Policy: 17 Apr 2006
Last Updated: 12 Apr 2018 (see Revision Log)

This policy defines a Change Control Rollback policy to be followed consistently across participating centers. This policy applies to scheduled system changes that impact the user experience. These scheduled system changes will include a recovery plan, outlined in advance of the change, in case the change is determined to be unsuccessful and rollback to a previous configuration is necessary.

  1. Each Center will have a Contingency/Recovery Plan for rollback to a previous configuration prior to making hardware or software changes.
  2. Each center will utilize any applicable Test and Development System or other non-production system to test changes prior to implementation. To the extent feasible, appropriate test methods that represent daily system workload should be used to enhance risk mitigation of adverse consequences of changes.
  3. HPC Help Desk staff will have access to a description of the scheduled system changes to facilitate identification of problems encountered by users following hardware/software changes.
