| # first, you need to disable the host from queue to avoid any jobs to be allocated to this host | |
| qmod -d all.q@thishost.com | |
| # wait for jobs to be finished execution on this host, then kill the execution script | |
| qconf -ke thishost.com | |
| # remove it from the cluster, this opens an editor, just remove the lines referring to this host | |
| qconf -mq all.q | |
| # remove it from allhosts group, this also opens an editor, remove lines referring to this host | |
| qconf -mhgrp @allhosts | |
| # remove it from execution host list | |
| qconf -de thishost | |
| # I normally go to the host and delete the sge scripts as well |

This is way old, so maybe this won't matter, but, I found that using inst_sge -ux -host hostname worked a treat. It's the only way I was able to get everything removed. I think one could discover how to do it by hand from observing the output from that script - it does more than I expected.
