Stop and Start issues in MariaDB Galera Cluster

We have Quarterly Patching maintenance activities on Linux operating system where
MariaDB Galera Cluster is hosted on all three Linux Nodes.

We need to bring MariaDB Galera environment before Linux RPM Patching Upgrade.

On completion of RPM Patching on Linux , we are facing issues in Starting up MariaDB Galera Nodes.

Generally Primary Node comes up with sudo galera_new_cluster command while remaining two nodes fail to come up.

Kindly advise , would it be advisable to use Automatic Bootstrap rather than Manual Bootstrap

We have Primary Node up where MariaDB Service is Active , Would it be advisable to

execute this command on Primary Active Node

MariaDB [(none)]> set global wsrep_provider_options='pc.bootstrap=YES';

and try to start remaining Nodes
