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.
• - remove system from all lvs/pybal active configuration
• - any service group puppet/heira/dsh config removed
• - remove site.pp (replace with role::spare if system isn't shut down immediately during this process.)

START NON-INTERRUPPTABLE STEPS

• - disable puppet on host
• - remove all remaining puppet references (include role::spare)
• - power down host
• - disable switch port
• - switch port assignment noted on this task (for later removal) (asw-c-eqiad:ge-7/0/24)
• - remove production dns entries
• - puppet node clean, puppet node deactivate, salt key removed

END NON-INTERRUPPTABLE STEPS

• - system disks wiped (by onsite)
• - system unracked and decommissioned (by onsite), update racktables with result
• - mgmt dns removed
• - switch port configration removed from switch once system is unracked..
