DR startup process is still running despite the cluster being UP

The Linux servers that our DR are running on were patched last night.  This morning I checked and under /opt/vertica/bin/adminTools and the cluster state shows UP.  We checked the processes and the startup Vertica process shows to still be running on 2 of the 3 DR servers.
[dradmin@hostname]$ ps -ef | grep rc | grep -v grep
root           1394    1     0 Aug21 ?        00:00:00 /bin/bash /etc/rc.d/rc 3
root           10305   1394  0 Aug21 ?        00:00:00 /bin/bash /etc/rc3.d/S99verticad start

Can we kill this process or is there something else we need to do first?
While it is highly likely that killing the process on the others two systems will not cause any problems, being that we are dealing with a database it is better to err on the side of caution.

1. Stop the Vertica cluster through adminTools
2. Run 'ps -ef | grep rc' to see if the rc script is still running
3. If it is still running you can kill -9 its PID
4. Start the Vertica cluster through adminTools

The likely cause is that after patching, the admin team initiated the S99verticad start command on all 3 cluster nodes and as Vertica only needs a start command from one, the other two commands sat lingering.
