This task will track the #decommission of server helium.eqiad.wmnet and its attached array of disks.
**Steps for service owner:**
[x] - all system services confirmed offline from production use
[x] - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place. (likely done by script)
[x] - remove system from all lvs/pybal active configuration
[x] - any service group puppet/hiera/dsh config removed
[x] - 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.
[
x] - 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.
[
x] - run homer on cumin host to update switch stack
[
x] - remove all remaining puppet references (include role::spare) and all host entries in the puppet repo
[
x] - remove ALL dns entries except the asset tag mgmt entries via netbox, run sre dns cookbook.
[] - reassign task from service owner to DC ops team member depending on site of servee.
**End service owner steps / Begin DC-Ops team steps:**
**DC OPS: This host has a disk array attached which needs to be decommissioned as well.**
[] - system disks removed (by onsite)
[] - determine system age, under 5 years are reclaimed to spare, over 5 years are decommissioned.
[] - IF DECOM: system unracked and decommissioned (by onsite), update netbox with result and set state to offline
[] - IF DECOM: mgmt dns entries removed.
