decom europium (was: reclaim europium)
Closed, ResolvedPublic


created as a subtask of T82239

server europium was gone from puppet and DNS but not fully decomed. OS was still installed and it was booting up when i connected to mgmt.

but in 2013 there was a comment from Asher that it can be reclaimed

i used it for installserver tests and reinstalled jessie, now it can really be reclaimed, go to spares or be used for something else

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/hiera/dsh config removed
  • - remove site.pp (replace with role::spare if system isn't shut down immediately during this process.)


  • - 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)
  • - remove production dns entries
  • - puppet node clean, puppet node deactivate, salt key removed


  • - 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: mgmt dns entries removed.
  • - IF RECLAIM: system added back to spares tracking (by onsite)
