Imam,

Are the nodes VMs or bare metal ?
Is the new xCAT management server on the same network as the existing
            management server ?

            system?



Hi,

I have a few nodes running centos 7.7 in a different cluster, and I would
like to bring them up another cluster (running xcat) - without rebuilding
them.  Initially, I thought I would just change IP addresses and copy the
xcat mgmt. node root SSH key over, but i figured that might not be the
right way to do it, as xcat would discover the nodes on boot-up and attempt
to build them.

what is the best method to bring on a node and add to xcat
environment without rebuilding it?
