Adding resources to capacity pools

Edit online

Divide storage resources into capacity pools to later restrict provisioning or optimization to a specific set of resources. You can also use capacity pools to track the used and available capacity for block and file storage on any set of storage resources. You can add resources to an existing capacity pool, or you can create a new capacity pool.

Before you begin

You must have Administrator privileges to perform this task.

About this task

You can add storage resources to a capacity pool from resource list pages such as the Storage Systems page and the Pools page.

You can add the following resource types to a capacity pool:

  • Storage systems
  • Storage pools
  • File systems of file storage systems

When you add a storage system to a capacity pool, any storage pool or file system that is an internal resource of that storage system is also indirectly assigned to the capacity pool.

Restriction: A resource can be assigned to only one capacity pool. When you attempt to add one or more resources to a capacity pool that are already assigned to different capacity pool, IBM Spectrum Control displays a message that lists the resources and their capacity pool assignments. When a message is displayed, ensure that you want to change the capacity pool assignments for the listed resources.

Procedure

To add one or more resources to a capacity pool, complete these steps:

  1. Open the appropriate list page for the resource you want to add. You can add an entire storage system, or you can add individual pools or file systems.
    • To add a storage system, in the menu bar, go to Storage > Block Storage Systems or Storage > File Storage Systems.
    • To add a storage pool, in the menu bar, go to Storage > Pools.
    • To add a file system, complete the following steps:
      1. In the menu bar, go to Storage > File Storage Systems.
      2. Select the storage system that contains the file system, then select View Details from the context-sensitive menu.
      3. From the Internal Resources list, click File Systems or Network Shared Disks.
  2. To add one or more resource to a capacity pool, select the resources in the list, and then select Actions > Add to Capacity Pool.
    If one or more capacity pools are defined, a list of capacity pools is displayed. If no capacity pools are defined, the Create Capacity Pool window is displayed so that you can add resources to a new capacity pool.
    Tip: The list of capacity pools and the Create Capacity Pool window shows capacity information. For the list of capacity pools, the Capacity column shows a bar that summarizes the used and free space in each capacity pool. In the Create Capacity Pool window, a capacity bar summarizes the used and free space of the resources that are being added to the new capacity pool. Move the mouse pointer over the bar to display a text summary and details of the capacity usage.
  3. Take one of the following actions:
    • If the Create Capacity Pool window is displayed, go to step 4.
    • If a list of capacity pools is displayed, add the selected resources to an existing capacity pool or to a new capacity pool.
      • To add the selected resource or resources to an existing capacity pool, select the appropriate row in the list of capacity pools, and click Save.
      • To add the selected resource to a new capacity pool, click Create Capacity Pool. The Create Capacity Pool window is displayed.
  4. In the Create Capacity Pool window, specify a name for the capacity pool.
  5. Optional: Specify a capacity pool description.
    Capacity pool descriptions appear in the list of capacity pools on the Capacity Pools page.
  6. Optional: Specify custom tags to associate any significant information with the capacity pool.
    You can specify up to three custom tags. The custom tags can be displayed in the list of capacity pools on the Capacity Pools page.
  7. Save the new capacity pool by clicking OK.
