How to put IC HEP into downtime

• Fill out the form in the GOC DB asap.


• Put the nodes in downtime in nagios. best to do this by host group: On the left hand side click "Hostgroup Overview", then e.g. BDII Servers (bdii-group) click on the group in brackets, then "Schedule downtime for all hosts in this hostgroup".


• Two days before, on the CE: Set /etc/sge-jobmanager/cluster.state to "Draining"
• At start of downtime: Set /etc/sge-jobmanager/cluster.state to "Closed"


• Two days before: Disable the queues on the CREAMCEs: glite-ce-disable-submission


• Stop the queues in SGE: On sgemaster03 (I can be root now) do 'qmon', then 'Queue control', click on grid.q and then on 'disable'.


• At the end of downtime: Stop the gatekeeper and use opportunity to clean out some home directories. Restart the gatekeeper and set /etc/sge-jobmanager/cluster.state to Production. Enable the queues in SGE (if applicable).
