The VMs will crash, and will be restarted once the failed HDD has been replaced and the data has been restored.

A live migration will be initiated, moving the affected VMs to a host that contains the replica data.

The VMs will remain operational on that host and continue to function normally with no noticeable impact

An HA event will occur, causing the affected VMs to restart on a node that contains the replica data.
