What is the Volume Group in Nutanix and How to create? And mount in client or Initiator machines
VGs enable you to separate the data vDisks from the VM's boot vDisk. This separation allows you to create a protection domain that consists only of the data vDisks for snapshots and cloning. In addition, VGs let you configure a cluster with shared-disk access across multiple VMs. Supported clustering applications include Oracle Real Application Cluster (RAC), IBM Spectrum Scale (formerly known as GPFS), Veritas InfoScale, and Red Hat Clustering. To attach the VG to multiple VMs when you use the aCLI, create it with a shared=true attribute. If you use Prism, answer yes when you attach the VG to a second VM. There are two ways to use Nutanix VGs: default VG and VGLB.
Note- : In short we are creating iSCSI disk, that we create in Windows server and allow the initiator to connect the disk and use it as a shared disk for MS Cluster.
