Volume groups provide a way to organize related volumes (LUNs) into groups so that the LUNs can be managed together.
Volume groups provide organizational units that you can use to manage collections of LUNs. Related LUNs can be grouped together in a volume group, and volume groups can be nested within other volume groups to provide a hierarchical organization of LUNs and volume groups.
With the Oracle vSphere Plug-In for Oracle Flash Storage Systems, you can create or remove volume groups. You can also manage the assignment of LUNs to volume groups from the vSphere Client.
