Service Owner steps
- all system services confirmed offline from production use
- set all icinga checks to maint mode/disabled while reclaim/decommmission takes place. (likely done by script)
- remove system from all lvs/pybal active configuration
- any service group puppet/hiera/dsh config removed
- remove site.pp, replace with role(spare::system) recommended to ensure services offline but not 100% required as long as the decom script is IMMEDIATELY run below.
- login to cumin host and run the decom cookbook: cookbook sre.hosts.decommission <host fqdn> -t <phab task>. This does: bootloader wipe, host power down, [] netbox update to decommissioning status, puppet node clean, puppet node deactivate, debmonitor removal, and run homer.
- remove all remaining puppet references and all host entries in the puppet repo
- reassign task from service owner to DC ops team member depending on site of server.
