decommision nembus
Closed, ResolvedPublic

Description

System nembus was reclaimed to spares back in December of 2015, but never added back to proper spare tracking and its out of warranty.

As such, the decom checklist will be fairly easy, since most of the items were done long ago:

  • - 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 if system isn't shut down immediately during this process.)

START NON-INTERRUPPTABLE STEPS

  • - 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) - asw-b-codfw:ge-5/0/12
  • - remove production dns entries
  • - puppet node clean, puppet node deactivate, salt key removed

END NON-INTERRUPPTABLE STEPS

  • - system disks wiped (by onsite)
  • - system unracked and decommissioned (by onsite), update racktables with result
  • - switch port configration removed from switch once system is unracked.
  • - mgmt dns entries removed.
