Scheduling the implementation of recommendations

Edit online

To schedule the implementation of optimization recommendations to tier storage, balance pools, and transform storage, use the Tasks page.

Before you begin

To schedule the implementation of storage optimization recommendations, you must have Administrator privileges.
The Schedule Execution action is available under the following conditions:
  • Recommendations were generated by the latest run of the tiering analysis, balance analysis, or transform-plan task.
  • An analysis-execution task is not running or paused.
  • An analysis-execution task was not already run for the latest set of analysis recommendations. For each run of the tiering analysis, balance analysis, or transform-plan task, you can complete only one run of the analysis-execution task.

About this task

When you define the schedule, an analysis-execution task is created for the implementation of the optimization recommendations.
Tip: The analysis-execution task implements the recommendations that were current when the analysis-execution task was defined. For example, you define a tiering-analysis task that runs daily. You review the recommendations every day and, on a Tuesday, you schedule an analysis-execution task to run on the following Friday. When the analysis-execution task runs on Friday, the recommendations that were current on Tuesday are implemented, even if more recent recommendations are available.

Procedure

  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 tiering analysis tasks that are related to servers, go to Servers > Servers, and click the Tasks tab.
  2. Locate the tiering analysis, balance analysis, or transform-plan task that you want to schedule.
  3. Right-click the task row and select Schedule Execution.
  4. On the Schedule Execution page, select the date and time that the recommendations are implemented and click Save.

Results

An analysis-execution task is created that you can monitor on the Tasks page. The name of the analysis-execution task is based on the name of the related tiering analysis, balance analysis, or transform-plan task. The Related Task column shows the related tiering analysis, balance analysis, or transform-plan task.

When the analysis-execution task runs on the scheduled date, the optimization recommendations are implemented. For example, volumes are moved to higher or lower tiers when storage-tiering recommendations are implemented.

Tip: In certain instances, running several optimization recommendations at the same time can cause one or more of the individual recommendation executions to encounter a Pool Exhaustion Exception. In these instances, the executions error out, rather than waiting for resources in the thread pool to become free. You might need to manually finish the execution of some recommendations, in particular, the old VDisk copy might not be removed, and you must remove it manually. To reduce the likelihood of encountering the issue again, contact IBM® Support for assistance in decreasing the total number of concurrent executions allowed.
