Description

This task will track the decommission-hardware of server db2043.codfw.wmnet

The first 5 steps should be completed by the service owner that is returning the server to DC-ops (for reclaim to spare or decommissioning, dependent on server configuration and age.)

db2043
Steps for service owner:

Steps for DC-Ops:

The following steps cannot be interrupted, as it will leave the system in an unfinished state.

Start non-interrupt steps:

  • - disable puppet on host
  • - power down host
  • - update netbox status to Inventory (if decom) or Planned (if spare)
  • - 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 (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-interrupt steps.

  • - label disk #3 as broken so it doesn't get re-used
  • - 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)
