In Unity All Flash models running OE version 4.2.x or later, all new pools created in the
Unisphere GUI are dynamic pools. New pools created in the Unisphere CLI and REST API are dynamic pools by default.
Note: You cannot change the RAID type of a dynamic pool after it is created. Also, you cannot shrink a dynamic pool or change its storage characteristics without deleting the storage resources configured in the pool and the pool itself. You can add drives to expand the pool.
To create a dynamic pool on All Flash models with Unity OE version 4.2 or later:
