Creating an application

When you create and associate storage resources with an application, you can monitor the capacity, space usage, and performance of the application and its subcomponents.

About this task

To create the filter for the application, you must identify the storage resources that the application uses.

In this scenario, you want to create an application that is called Book Sales DB. The Books Sales DB application uses volumes with names that begin with bksales that are on a Storwize V7000 storage system.

To ensure that the filter does not retrieve storage resources that are on other hosts or storage systems:
  • You add the names of the volumes or a pattern that matches the names of the volumes.
  • You add the name of the storage system or a pattern that matches the name of the storage system.

Procedure

  1. From the Groups menu, click Applications.
  2. Click Create Application.
  3. Enter the information about the application that you want to create, and click Create.
  4. On the Select a Method page, click Assign storage resources to the application.
  5. On the Select a Resource Type page, click A selection of volumes that match a pattern.
  6. Type the pattern that matches the names of the volumes that the application uses for storage.
    For example, to associate the volumes that the application for the Books Sales DB uses, you type bksales_ws*.
  7. Click Belonging to and then click Storage System.
  8. Type the name of the storage system or the pattern that matches the name of the storage system.
  9. To check that the filter retrieves the correct storage resources, click Preview.
    If you want to change the filter, click Close and make your changes.
  10. Click Save.
    Important:

    When you use a filter to add specific resources to an Application, those specific resources appear as Members in the Application and only resources directly related to the specific Members resources appear in the Application under Related Resources. Resources that are not directly related to the specific Member resources do not appear in the Application under Related Resources.

    For example, when you use a filter to add specific volumes from a specific storage system to an Application, only those volumes that match the filter appear as Members in the Application. Under Related Resources for the Application, you will see only those resources (storage system, pools, managed disks, RAID arrays, drives, etc.) that are directly related to the specific volumes you added as Members to the Application. For example, if the storage system associated with those specific volumes that you added to the Application via a filter contains other volumes that did not match the filter, then those volumes will not appear as Members or as Related Resources in the Application. You would have to add those other volumes to the Application via a filter or you would have to add a resource directly related to those other volumes to the Application via a filter.

Results

You can now view information about the capacity, space usage, and performance of the storage resources on the Overview page for the application.
