Nutanix volume groupsare collections of vDisks that can be exposed to virtual machines or physical hosts using iSCSI protocol. Nutanix volume groups have a shared attribute that allows multiple VMs to access them concurrently.

In the step for attach the volume group to the RAC VMs, he must create it with an attribute of shared = true. This is because if the volume group is not created with shared = true, then only one VM can access it at a time, which would prevent Oracle RAC from working properly.
