This task will track the decommissioning of lvs400[1-4].ulsfo.wmnet. All four of these hosts are well out of warranty, and lvs400[567] have been purchased to replace them.
lvs400[567]'s setup is tracked via T178436, and they are ready to be placed into service.
This task is currently assigned to @bblack, since I've (@robh) been working directly with him with the decom/replacements in ulsfo. This may be retasked to others in #traffic as needed.
lvs4001:
[x] - all system services confirmed offline from production use
[x] - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place.
[x] - remove system from all lvs/pybal active configuration
[x] - any service group puppet/hiera/dsh config removed
[x] - remove site.pp (replace with role::spare if system isn't shut down immediately during this process.)
START NON-INTERRUPPTABLE STEPS
[x] - disable puppet on host (hosts were powered down and unracked before this step)
[x] - remove all remaining puppet references (include role::spare) https://gerrit.wikimedia.org/r/366037
[x] - power down host (host is not cabled up, so it cannot power up)
[x] - disable switch port (port was never set back up in new racks, so its disabled)
[x] - switch port assignment noted on this task (for later removal)
[x] - remove production dns entries
[x] - puppet node clean, puppet node deactivate, salt key removed
END NON-INTERRUPPTABLE STEPS
[] - system disks wiped (by onsite)
[x] - swapped places with new systems as needed, and now resides in rack with no cabling.
[x] - mgmt dns entries removed.
[] - system unracked and decommissioned (by onsite), update racktables with result
