+Changing the Scope of the Primary Storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Scope of a Primary Storage can be changed from Zone-wide to Cluster-wide
+and vice versa when the Primary Storage is in Disabled state.
+An action button is displayed in UI for each Primary Storage in Disabled state.
+
+|change-storage-pool-scope-via-ui.png|
+
+Scope change from Cluster to Zone will connect the Primary Storage to all Hosts
+of the zone running the same hypervisor as set on the storage pool.
+
+|change-storage-pool-scope-to-zone.png|
+
+Scope change from Zone to Cluster will disconnect the Primary Storage from all
+Hosts that were previously connected to the Primary Storage and are not a part
+of the specified Cluster. So, if there are running VMs on such hosts using this
+Storage Pool, they cannot be disconnected from the hosts. In this case the
Scope
+change operation will error out.
+The user VMs need to be stopped or migrated and system VMs need to be destroyed
+while the primary Storage is disabled, before attempting the operation again.
+listAffectedVmsForstorageScopeChange API can be used to get the list of all
such VMs.
+
+This might be a long running operation depending on how many hosts are there
+in the zone which need to be connected or disconnected to the storage pool.
+
+This feature is tested and supported for the following hypervisor and storage
+combinations:
+
+- KVM with NFS
+
+- KVM wite CEPH/RBD
+
+- VMWare with NFS
+
+It is possible to use this functionality with other configurations but some
+manual intervention might be needed by the Administrator to make it work.
