Description

This is a spare, powered down system requiring decommission.

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::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)
  • - remove all remaining puppet references (include role::spare)
  • - remove production dns entries
  • - puppet node clean, puppet node deactivate

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.
