LUN size and type
When you create a LUN, you must specify the LUN size and the type for your host operating system.
The LUN Multiprotocol Type, or operating system type, determines the layout of data on the LUN, the geometry used to access that data, and the minimum and maximum sizes of the LUN. After the LUN is created, you cannot modify the LUN host operating system type.
