This will track the decommission-hardware of graphite2002 and the return of the host to the spares pool (as its less than 4 years old.)

This checklist is able to be copied and pasted into phabricator hardware request tasks for reclaiming systems to spare or decom.

• - all system services confirmed offline from production use
• - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place. (handled by wmf-decommission-host)
• - remove system from all lvs/pybal active configuration
• - any service group puppet/heira/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
• - update status in netbox (planned for spare)
• - disable switch port & update to asset tag name on switch port description
• - remove all remaining puppet references (include role::spare)
• - remove production dns entries
• - puppet node clean, puppet node deactivate (handled by wmf-decommission-host)
• - 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 (handled by wmf-decommission-host)

END NON-INTERRUPPTABLE STEPS

• - remove mgmt dns entries for the hostname, leave the asset tag as this is going to spares
• - system disks wiped (by onsite)
• - remove hostname label of 'graphite2002' as this is returning to spares pool
• - leave host in rack and cabled after disk wipe, as its now a spare pool system.
