This means be a dedicated network, solely used for management only? > I have tried setting the First Boot Device to PXE and warm booting them boot > they still did not come back. Did the PXE server move with the installation? Are these diskless nodes and booted always by PXE? Was there a DHCP server in place before the move and the nodes don't get any proper addresses now (means the management network might be use hard coded addresses)? Are and/or were the nodes on a private network behind the headnode of the cluster and thus w/o any access from outside the cluster? > I really don't know much about SGE and would greatly appreciate any advice > that would help me trouble shoot this and get them back on line. I agree with Daniel, that you first need to make the nodes accessible again. Then one can look into the SGE setup. -- Reuti _______________________________________________ SGE-discuss mailing list SGE-discuss@liv.ac.uk https://arc.liv.ac.uk/mailman/listinfo/sge-discuss
