There are certain check marks which you need to fulfill,
>> We can see that you have SSD read cache configured so you can't create normal SSD Vitual Disk Group (VDG) with the presense of SSD read cache. At a time either SSD read cache or SSD VDG can exists, both can't exist together in same Pool. So delete SSD read cache as Arun mentioned otherwise you can plan SSD performance tier VDG in Pool B as well.
>> Next thing you require "Advanced Data Services Suite" license because you are using two different type of drives. Here you are trying to create new SSD VDG with 4 new SSD drives with the presense of other normal SAS drives in the system. So this new SSD VDG will be considered as Performance tier which can't be possible without proper license installed. Check if this license installed or not.
Hope this helps!
