Describe the issue:

The process of multiple Storage System creation is not described in documentation. There is a logic behind the flow of UI Storage System creation in regards to namespaces. Limits on number of Storage System should be described in the docs.

Describe the task you were trying to accomplish:

Create first Storage System on OCP cluster with ODF installed, using management-console.
Create second Storage System on OCP cluster with ODF installed, using management-console.
Create three or more Storage Systems on OCP cluster with ODF installed. - negative scenario.

Suggestions for improvement:

We don't have the chapter specifying the steps User performs to create a Storage System

specify that for IBM FlashSystem StorageSystem, the Storage System will always be created in "openshift-storage" and header should reflect the same when this option is selected.

Additional information:

Following the bug and the comment 16 https://bugzilla.redhat.com/show_bug.cgi?id=2271593#:~:text=Private-,Comment%2016,-Sanjal%20Katiyar
there is logic behind the Storage System creation:

------

For the very first StorageSystem/StorageCluster creation this header will show namespace as "openshift-storage" (ODF operator install namespace).

Now, from 4.15 onwards we support multiple StorageSystems (1 internal + 1 external) (refer: https://issues.redhat.com/browse/RHSTOR-4422). So, for the second "Ceph" based StorageSystem/StorageCluster header will show the namespace as "openshift-storage-extended" which is created by UI (if not already existing) (this should be well documented in 4.15 docs as well).

We do not support more than 2 "Ceph" clusters, so header in that case is irrelevant (irrespective of any value which it might/might-not be showing) as "Next" button will always be blocked and user won't be able to create any more clusters.

Finally, IBM FlashSystem StorageSystem, this will always be created in "openshift-storage" and header should reflect the same when this option is selected.

Emphasize that from 4.15 onwards we support multiple StorageSystems 1 internal + 1 external. Describe the form that needs to be filled.

Screenshot with updated UI on ODF 4.16 is added.
