When you create Storage Virtual Machine (SVM), the language is set for the SVM. The language of the
SVM determines the default language setting for volumes in that SVM. You can modify the language of an SVM.
You can specify the language for a volume when creating a volume and it can be different from the
language of an SVM. If you do not specify the language for a volume then it inherits the language
setting of its SVM. After the volume is created, you cannot modify the language of a volume.
Therefore, you must be aware of the available language options.
