Gentlemen,
Are there any arguments against adding subsequent node to CM 6.x cluster during Business Hours ?
I've been looking through Admin Guide, Installing Guide.
Nowhere exists any warning about recommendation to move such an operation to non-business time interval.
Thank you.

I think it's not hours for the whole process but it needs much system ressources like processor.
With RTMT you can watch your DB replication Status under "performance-> "yourfirstserver" -> Number of Replicates Created and State of Replication->Replicate_State"
This displays the state of replication: Thus 0 = Initializing (Will be 0 if server is not defined OR if server is defined but realize template is not done); 1 = Replicates created but their count isn't right; 2 = Replication is good; 3 = Replication is bad in the cluster; 4 = Replication Setup didn't succeed
After adding a node, your count should say "2" on every server.

it's not recommended because at that time a copy of almost all the DB tables needs to be pushed to the server, SDL links need to be created, RIS info, etc
depending on the size of the DB it can take quite some time to push all the info and that causes some high CPU
also it's best practice to restart the cluster after the addition of a new server to sync the SDL layer, so afterhours is always the best choice

Jaime,
Can you please approx. estimate total time (in hours) of the whole process of adding subsequent node to PUB with ~500 phones.
Please, explain what do you mean in saying "restart the cluster" ?
What actions and where should perform to complete this ?
Thank you.
