1. Install an aws openshift cluster
2. Create 6 extra storage classes(any sc is ok)
3. Overwriter all the sc with the storageclass.kubernetes.io/is-default-class=false and check all the sc are set as undefault 
4. Overwriter all the sc with the storageclass.kubernetes.io/is-default-class=true 
5. loop step4-5 several times

Overwriter all the sc with the storageclass.kubernetes.io/is-default-class=false, sometimes recovered by the driver operator

Overwriter all the sc with the storageclass.kubernetes.io/is-default-class=false should always succeed
