AWS Create ONTAP volume from existing Storage Virtual Machines(SVM) via Cloudformation

Question

I want to create an `AWS ONTAP Volume` only **Based on the existing Storage Virtual Machines(SVM)** .

I have `SVM` ID and `Name` are available with me in order to  use then in the new stack which i am creating to spin the new Volume(s).

```
Filesystem ID:  fs-00b23d16e032150db  
SVM ID is :  svm-04c2e2830ff42097e
SVM Name:  AWSDemosvm
```

**I tried Below:**  But did not worked.

There is catch in the template below where as per documentation it says clearly that it needs string thus you don't  required `!ImportValue` here. just remove that.

Secondly,  there is also another problem in the below code as you defined the `CoolingPeriod: 0`    which is not correct as value can not be zero either it should be minimum 2 or greater.
