To answer your questions:

    When forming the virtual storage on the new cluster, the previous data in the Node-C is still available?

Yes, the previous data in Node-C will still be available when forming the virtual storage on the new cluster, assuming the hard drives or solid state drives (SSDs) containing the data are not damaged.

When you remove a node from a HCI cluster, the data on that node is not deleted. Instead, the data is replicated to the remaining nodes in the cluster. This ensures that the data is still available even if a node fails.

When you add Node-C to a new cluster, the cluster will detect the existing data on the node and import it into the new virtual storage. This process is called data migration.

    After the Node-C was broken, the data was lost when removed from Cluster-A?

No, the data was not lost when Node-C was removed from Cluster-A. As mentioned above, the data on a node in a HCI cluster is replicated to the other nodes in the cluster. This means that the data is still available even if a node fails.

    The data before is erased when forming the new virtual storage in the new cluster?

No, the data before is not erased when forming the new virtual storage in the new cluster. The data migration process will import the existing data on Node-C into the new virtual storage.

Important: It is important to note that data migration is a complex process and should only be performed by qualified personnel. If you are not comfortable performing the data migration yourself, you should contact the vendor of your HCI software for assistance.

Additional information:

    If the hard drives or SSDs containing the data on Node-C are damaged, the data will be lost.
    If the data on Node-C is not critical, you can simply wipe the drives and start fresh when you add Node-C to the new cluster.
    If the data on Node-C is critical, you can use a data recovery service to try to recover the data.
