This task will track the decommission-hardware of server dns4002
dns4002:
- - all system services confirmed offline from production use - not really but per past discussion dns host can just auto depool for decom steps
- - 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
- - system unracked and decommissioned (by onsite), update netbox with result and set state to offline
- - mgmt dns entries removed.
