storageVirtualMachineRoot

A Boolean flag indicating whether this volume is the root volume for its storage virtual machine (SVM). Only one volume on an SVM can be the root volume. This value defaults to false. If this value is true, then this is the SVM root volume.

This flag is useful when you're deleting an SVM, because you must first delete all non-root volumes. This flag, when set to false, helps you identify which volumes to delete before you can delete the SVM.
