Jump to: navigation, search

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.)

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)

[] - 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: mgmt dns entries removed.

[] - IF RECLAIM: system added back to spares tracking (by onsite)
