This API provides information about all the VolumeGroups in the VirtualIOServer.

/rest/api/uom/VirtualIOServer/{VirtualIOServer_uuid}/VolumeGroup/{VolumeGroup_uuid}

This API provides information about a particular VolumeGroup in the VirtualIOServer given its UUID.

When you install a VirtualIOServer, one volume group (the root volume group, called rootvg) is automatically created that contains the base set of logical volumes required to start the system, and any other logical volumes you specify to the installation script. The rootvg includes paging space, the journal log, boot data, and dump storage, each in its own separate logical volume. No operations can be performed on rootvg. Virtual Disks inside rootvg are not be listed.

The REST API for volume Group provides the following information:

Free Space in the Volume Group in MBytes
Media Repository in Volume Group, if any
Physical Volumes from which Volume Group is created
Virtual Disks created in the Volume Group
