Thanks a lot.

But we want to block all the communications to/from the disconnected VDC without reboot it.

not sure if that's what you're looking for but you can use auto_bootstrap=false in your yaml
file to prevent nodes from bootstrapping themselves on startup. This option has been removed
and the default is true. You can add it to your configuration though. There's a bit of documentation

Hi, All,

We are using Cassandra 2.0.7 in a multi DCs environments.  If a connected DC is powered off,
we use the ‘nodetool removenode’ command to remove it from the connected DCs.
But we found that once the disconnected DC is powered on, it will connect to other DCs automatically.

How can we prevent a disconnected DC from coming back automatically?

Thanks a lot
