The following are required to run the Storage Provisioning Option in a Central Admin Server Option (CASO) environment:
The Storage Provisioning Option must be installed on the media server to which the storage array is attached.
If the storage array is attached to a managed media server, install the Storage Provisioning Option on that managed media server. You do not need to install the Storage Provisioning Option on the central administration server if the storage array is not attached to it.
The Central Admin Server Option must use a centralized database.
