Exadata Virtualized DB node restore

There are two common scenarios when we may need this: An existing DB node has crashed and is unrecoverable (due to some failure and non-availability of any backups. Though some of the things may need to be done even if the backups were available). We have an existing Exadata rack that is virtualized. Now there is a new DB node and the existing clusters need to be extended to include the VMs on this new node. I recently faced the first scenario where a virtualized DB node crashed and wasn’t recoverable. A bare metal DB node restore is a relatively simple procedure where we just have to reimage the node, create the needed directories, users etc and add it to the RAC cluster. In case of virtualization, the creation of VMs is an additional step that needs to be done. That makes it slightly more complex. ...
