How to CLEAN shutdown of only one node in a cluster - 19c RAC

hi,

We have a Linux 7 box that needs to be restarted.

1) Will the cluster automatically add the node when the box is up again?

2) Do I still need to shutdown all the instances on that node, Or will that take care of itself too?

srvctl stop instance -i inst1 -d db1 -o immediate

srvctl stop instance -i inst1 -d db2 -o immediate

srvctl stop instance -i inst1 -d db3 -o immediate

Yes, I have 3 instances running, each one belongs to different RAC database (db1, db2, db3).

I have 19c 19.0.0.4 RAC on Linux 7 - The cluster has 3 nodes. The node 1 box needs to be restarted.
