This task will track the decommission-hardware of leased servers elastic200[01-23].

These are being replaced with new elastic sytems on T210450. Once those new systems are online, this should immediately start being processed as the leases are due back this month (December 2018).

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.)

(Please do not just use the combined checklist, post a comment stating what you did and to what servers.)
Steps for service owner:

• - 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::system)
• - unassign service owner from this task, check off completed steps, and assign to @RobH for followup on below steps.

Steps for DC-Ops:
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.

• - system disks wiped (by onsite)
• - system unracked and decommissioned (by onsite), update netbox with result
• - switch port configration removed from switch once system is unracked.
• - add system to decommission tracking google sheet
• - mgmt dns entries removed.
• - system set aside for lease return
