In a hyper-converged infrastructure (HCI) environment like the one you described, the availability and data handling can vary depending on the specific HCI software and configuration. However, I can provide some general insights:

• Data Availability in New Cluster (Node-C):

  
  

  
  
  
  When you form a new cluster with Node-C and other new nodes, the previous data that was synchronized on Node-C should still be available on the local storage devices (HDDs/SSDs) of Node-C, assuming those storage devices were not physically removed or wiped.
  However, whether that data can be seamlessly integrated into the new cluster's virtual storage depends on the HCI software and configuration. You may need to import or attach the existing storage volumes or virtual machines to the new cluster. Consult the documentation and procedures of your specific HCI solution for guidance on data migration and integration.
  
  
• Data on Node-C When Removed from Cluster-A:

  
  

  
  
  
  When Node-C is removed from Cluster-A due to a hardware issue, the data on Node-C should still be intact on its local storage devices, assuming those devices were not physically damaged or wiped during the repair process.
  
  
• Data Erasure When Forming New Virtual Storage:

  
  

  
  
  
  Forming a new virtual storage cluster in the new cluster involving Node-C should not automatically erase the data on Node-C's storage devices. However, the data on Node-C may not be automatically integrated into the new virtual storage cluster.
  You will likely need to perform specific actions to import or attach the existing data on Node-C to the new cluster's storage. This process typically involves configuring storage policies, creating virtual disks, and attaching existing data to virtual machines.
