Creating ranks

Complete this task to create ranks and to specify their arrays and extent pools.

Note: If you are building a configuration in simulated mode or you are importing a real-time configuration into the simulated configurator, extent allocation per rank in an extent pool might not be the same. This means that the rank extent allocations that are created in simulated mode or imported as part of a real-time configuration might not match the allocation when you compare applied and imported configurations to real-time configurations at the rank level, although the extent usage is equivalent. The real-time configuration extent allocation at the rank level will be configured appropriately.

Perform the following steps to create ranks:

  1. In the navigation, select Real-time manager or Simulated manager > Configure storage > Ranks. On the Ranks main page, in the Select storage unit drop-down list, select a storage unit.
  2. From the Select Action list, select Create..., and then click Go. The Create Rank – Select array for rank page is displayed.
  3. In the Select column, select an array. Then click Next. The Create Rank – Define rank properties page is displayed. The Rank number is provided by default.
    Note: If there are no available arrays for selection, you can create one by clicking the Create new array button. When you have finished creating an array, you are returned to this page, and the array that you created is available for selection.
  4. Specify the Storage type and then click Next. The Create Rank – Select extent pool page is displayed.
  5. Optionally, you can select one extent pool. In the Select column, select an extent pool. The click Next. The Create Rank – Verification page is displayed.
    Note: If there are no available extent pools for selection, you can create one by clicking the Create new extent pool button. When you have finished creating an extent pool, you are returned to this page, and the extent pool that you created is available for selection.
  6. In Create Rank – Verification, review the attributes and values to verify that they are correct. If the attributes and values are not correct, click Back as appropriate to return and then specify the correct values. Otherwise, click Finish to complete the rank creation process.
If you are creating a new logical storage configuration, return to Creating a custom logical storage configuration and complete the rest of the steps.
