Description

This task will track the decommission-hardware of server db2068.codfw.wmnet

With the launch of updates to the decom cookbook, the majority of these steps can be handled by the service owners directly. The DC Ops team only gets involved once the system has been fully removed from service and powered down by the decommission cookbook.

db2068

Steps for service owner:

End service owner steps / Begin DC-Ops team steps:

  • - disable switch port / set to asset tag if host isn't being unracked / remove from switch if being unracked.
  • - Label RAID controller, mainboard and disks as broken so they don't get re-used T235366 T180927
  • - system disks wiped (by onsite)
  • - determine system age, under 5 years are reclaimed to spare, over 5 years are decommissioned. If uncertain, ask @wiki_willy.
  • - 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.

Talked to @MoritzMuehlenhoff about this, and as it has been done with other cases, given that the host is unusable anyways, we'll proceed as usual and just labeling the storage as broken so it doesn't get reused (which is already done).
