Users can now change an initialized Data Center type to Shared or Local. The following updates will be available: 1. Shared to Local - Only for a Data Center that does not contain more than one host and more than one cluster, since a local Data Center does not support it. The Manager will validate and block this operation with the following messages: CLUSTER_CANNOT_ADD_MORE_THEN_ONE_HOST_TO_LOCAL_STORAGE VDS_CANNOT_ADD_MORE_THEN_ONE_HOST_TO_LOCAL_STORAGE 2. Local to Shared - Only for a Data Center that does not contain a local Storage Domain. The Manager will validate and block this operation with the following message: ERROR_CANNOT_CHANGE_STORAGE_POOL_TYPE_WITH_LOCAL. This update is useful for data domains that are used to move virtual machines or templates around.
Assigning to Avital for review. Avital, I don't think we need to go as far as adding the error messages, but a short explanation of the allowed updates would be good. I suspect there are also places in the docs set where we say that such updates are not allowed, so those will need to be removed if they exist.
