Once a Tenant is created in HCP of a defined size, can it be shrinked later
Yes, it can be shrinked, unless you try to make it smaller than the total amount of space allocated to all its namespaces. Here is what happens if you do this:
In general, it's important to understand that tenants are administrative/management units and don't actually take any space, as opposed to namespaces that contain the "real" data.
Namespaces can also be shrinked - that is, have their hard quota decreased - as long as the new hard quota value isn't less than the amount of data already in that namespace.
Thanks for your valuable information.
