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:
- In the navigation, select . On the Ranks main page, in the Select storage
unit drop-down list, select a storage unit.
- From the Select Action list, select Create..., and then click Go. The

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.
- Specify the Storage type and then
click Next. The Create Rank – Select extent
pool page is displayed.
- 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.
- 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.
