Pausing, resuming, and canceling the implementation of recommendations

IBM Spectrum® Control uses analysis-execution tasks to implement optimization recommendations to tier storage, balance pools, and transform storage. To pause, resume, and cancel analysis-execution tasks, use the Tasks page.

To pause, resume, or cancel analysis-execution tasks, you must have Administrator privileges.
  1. From the menu bar, go to the Tasks page, a resource list page for a resource type, or a resource detail page for a specific resource.
    For example, to view the analysis-execution tasks that are related to servers, click Servers > Servers, and click the Tasks tab.
  2. Locate the analysis-execution task that you want to pause, resume, or cancel.
  3. Right-click the task row and select Pause, Resume, or Cancel.

    The Pause action is only available when the analysis-execution task is running.

    The Resume action is only available when the analysis-execution task is paused.

    The Cancel action is available when the task is running or paused.

When you pause, resume, or cancel analysis-execution tasks, the following processing occurs:
Pause
The status of the analysis-execution task changes to Paused and the recommendations that are being implemented are suspended.
Resume
The status of the analysis-execution task changes to Running and the recommendations are resumed.
Cancel
The status of the analysis-execution task changes to Canceled and the recommendations that are being implemented are stopped. Any recommendations that are already implemented for this analysis-execution task are not rolled back. For example, a recommendation is generated to move a volume from pool_a to pool_b. If this recommendation is already implemented before the task is canceled, the volume remains in pool_b. Use the Analysis Execution page to determine which recommendations were implemented for the task before the task was canceled.
You cannot restart an analysis-execution task that is canceled. If you want to implement the same set of recommendations again, you must complete the following steps:
  1. Delete the analysis-execution task that you canceled.
  2. Use the Schedule Execution action for the tiering analysis, balance analysis, or transform-plan task to create an analysis-execution task.
