Unity Block Replication configuration

Hi Everyone.

I'm contacting you with the following inquiries regarding the Unity Block Replication configuration.

In case the main storage failure occurs after the customer configures Replication in a situation where it is not yet decided whether to configure Sync or Async

When performing Failover in Target Storage Manager, if Storage Rescan is performed in the VMware environment, it is created with the same DataStore name as the existing one and asks whether the existing GuestVM can be run immediately and if the DataStore name is different, it asks whether the GuestVM must be manually registered in VMware. .
