Understanding the Root Volume

About this chapter

This chapter introduces you to the storage system's root volume, which contains special directories and configuration files that help you administer your storage system.

About the root volume

The storage system contains a root volume that was created when the storage system was initially set up at the factory. Unless the installer selected a unique volume name during setup, the default root volume name, /vol/vol0, is used.

For storage systems that have Data ONTAP 7.0 or later installed at the factory, the root volume is a FlexVol volume. Systems installed with earlier versions of Data ONTAP have a traditional root volume.

For more information about traditional and FlexVol volumes, see the Storage Management Guide.
