This is a priority since it's taking space in rack B4
iron was bought in January 2011, it's over eight years old! Before this host can be removed, two remaining use cases need to be moved (install access for WMCS and Yubikey bastion)
[x] - all system services confirmed offline from production use
[x] - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place.
[x] - remove system from all lvs/pybal active configuration
[x] - any service group puppet/heira/dsh config removed
[x] - remove site.pp (replace with role(spare::system) if system isn't shut down immediately during this process.)
START NON-INTERRUPPTABLE STEPS
[x] - disable puppet on host
[x] - power down host
[ ] - disable switch port
[ ] - switch port assignment noted on this task (for later removal)
[x] - remove all remaining puppet references (include role::spare)
[x] - remove production dns entries
[x] - puppet node clean, puppet node deactivate
[x] - remove dbmonitor entries on neodymium/sarin: sudo curl -X DELETE https://debmonitor.discovery.wmnet/hosts/${HOST_FQDN} --cert /etc/debmonitor/ssl/cert.pem --key /etc/debmonitor/ssl/server.key
END NON-INTERRUPPTABLE STEPS
[] - system disks wiped (by onsite)
[] - IF DECOM: system unracked and decommissioned (by onsite), update racktables with result
[] - IF DECOM: switch port configration removed from switch once system is unracked.
[] - IF DECOM: add system to decommission tracking google sheet
[] - IF DECOM: mgmt dns entries removed.
