m4 (eventlogging - db1107 and db1108) has two proxies: dbproxy1004 and dbproxy1009, which are currently not in use (and have not been in used for more than a year: https://gerrit.wikimedia.org/r/#/c/operations/dns/+/425231/).
```
# host m4-master
m4-master.eqiad.wmnet is an alias for db1107.eqiad.wmnet.
db1107.eqiad.wmnet has address 10.64.0.214
```
These two hosts were purchased in 2011 and of course out of warranty.
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.)
dbproxy1004
Steps for service owner:
[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::system) https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/525527/
[x] - unassign service owner from this task, check off completed steps, and assign to @robh for followup on below steps.
Steps for DC-Ops:
The following steps cannot be interrupted, as it will leave the system in an unfinished state.
**Start non-interrupt steps:**
[x] - disable puppet on host
[x] - power down host
[x] - update netbox status to decom (if decom) or Planned (if spare)
[x] - disable switch port
[x] - switch port assignment noted on this task (for later removal) asw2-b-eqiad:ge-5/0/12
[x] - remove all remaining puppet references (include role::spare)
[x] - remove production dns entries
[x] - puppet node clean, puppet node deactivate (handled by wmf-decommission-host)
[x] - 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)
[] - 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.
[] - IF RECLAIM: system added back to spares tracking (by onsite)
