I have a condo model cluster where I semi-regularly need to add nodes so I have a documented procedure. It is possible that other things in xCAT are already configured to allow these steps to work so it might be helpful to see the exact problems that you're seeing at your sites. One thing that I think is important for my specific nodeadd commands is that the hosts table must be setup with regular expressions to automatically assign IP addresses.
Here are the commands that I run: For each node you'll be adding: nodeadd $HOSTNAME groups=$LIST_OF_GROUPS End for loop makehosts makedns makeconservercf - This one is probably not strictly required at this point, but it is on my list. nodediscoverstart noderange=$HOST_RANGE At this point power on each node in the range in order. I usually wait for each node to get past the BIOS POST before powering on the next one. When you're done run nodediscoverstop I hope this helps, Mike Robbert On 8/14/19 12:44, Jacob Bonek wrote: CAUTION: This email originated from outside of the Colorado School of Mines organization.

I'm about to add 15 more nodes to our cluster and would prefer not to have to add them all manually. I normally fumble about with sequential for a while each time I add nodes before giving up. Does anyone happen to have a procedure they would be willing to share with me on how to properly perform sequential discovery?
