decom niobium/WMF3428
Closed, ResolvedPublic

Description

This host is already powered off in eqiad, and should have its decom completed.

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