Changing modes for data already in cache

After data has been placed in cache, the cache residency mode (bind or priority) and prestaging
mode (yes, no) cannot be changed. If you need to change the cache residency mode or prestaging
mode, you must first release the data from cache and then place the data back into cache with
the new settings.
