Implementing recommendations immediately
To implement optimization recommendations to tier storage, balance pools, and transform storage, use the task detail pages. For example, use the Balance Analysis page to implement the recommendations to balance pools.
Before you begin
About this task
IBM
Spectrum Control uses analysis-execution tasks to implement optimization
recommendations. When you implement recommendations for a tiering
analysis, balance analysis, or transform-plan task, the following
process takes place:
- An analysis-execution task is automatically created so that the recommendations can be implemented.
- The analysis-execution task runs immediately and 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.
You can view analysis-execution tasks on the Tasks page. The Related Task column shows the related tiering analysis, balance analysis, or transform-plan task.
The Execute 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 was not already run for the latest set of recommendations.
- An analysis-execution task is not running or paused.
Procedure
-
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, go to , and click the Tasks tab.
- Locate the tiering analysis, balance analysis, or transform-plan task that you want to implement.
- Right-click the task row and select View Details. For example, the Balance Analysis page opens if you select a balance-analysis task.
- Click Execute. An analysis-execution task is created and immediately implemented.
Results
- View the task status on the Tasks page.
- View the status of individual task recommendations on the Analysis Execution page.
- View the task logs from the Tasks page or from the Analysis Execution page. You can view detailed informational, warning, and error messages that are related to the task. You can use this information to troubleshoot any errors that might occur when a task is run.
