Hi David,
If you are using diskless nodes, on e you have updated the tables all you
need to do is
nodeset <nodename> netboot
And then reboot the nodes. This should automatically change the relevant
tftp files.
However if this is disk full, then you need to run the following command
nodeset <nodename> install
This should then reconfigure your kick start files and the tftp files and
once rebooted it should pick up the relevant files
I hope that helps
Regards,
Arif
