terbium was replaced by mwmaint1001, it can reclaimed to spares or decomissioned (probably the latter as it's 5.5 years old)

Check list:

• - all system services confirmed offline from production use
• - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place.
• - remove system from all lvs/pybal active configuration
• - any service group puppet/hiera/dsh config removed
• - remove site.pp (replace with role::spare::system if system isn't shut down immediately during this process.)

START NON-INTERRUPPTABLE STEPS

• - disable puppet on host
• - power down host
• - disable switch port
• - switch port assignment noted on this task (for later removal) asw2-c-eqiad:ge-7/0/22
• - remove all remaining puppet references (include role::spare)
• - remove production dns entries
• - puppet node clean, puppet node deactivate
• - 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.
