Description

This task will track the decommission of the old mw2231. the task will be a little bit different from the other decommission tasks since we are are not changing any configuration for the mw2231, We are just replacing this server with an other server that will use the same configuration. This task will is to keep tack of the server in the decommission stage.

what needs to be done?

- IF DECOM: system unracked and decommissioned (by onsite), update netbox status to offline and remove from rack in netbox.
- IF DECOM: add system to decommission tracking google sheet

Complete

It seems that Netbox's ip address has not been updated and still reports graphite2002 in the DNS name, see
https://netbox.wikimedia.org/ipam/ip-addresses/687/

At the same time the correct name seems to still be attached to the old one in:
https://netbox.wikimedia.org/ipam/ip-addresses/1122/

Could you please verify it @Papaul ?

@Volans do we have a template in place when a server name changes from X to Y to also update DNS in netbox. The last steps that I recalled were
1- change switch port description
2- change physical label

Those were what DC-ops used to do? If i am missing something please advice. Thanks

@Papaul given we're setting the DNS name of the ip address in Netbox, that one too needs to be updated, see the links above:

IP: 10.193.2.251/16
Assignment:	mw2231 (mgmt)
DNS Name:	graphite2002.mgmt.codfw.wmnet

and

IP: 10.193.1.118/16
Assignment:	mw2231 old (mgmt)
DNS Name:	mw2231.mgmt.codfw.wmnet

My understanding is that 10.193.1.118 is the mgmt IP assigned to the new mw2231 (but please double check it). In that case we should attach Netbox IP 10.193.1.118/16 to the mw2231's mgmt interface and delete the 10.193.2.251/16 if is not anymore used.

@Volans confirm that 10.193.1.118 is indeed the mgmt IP address for mw2231 and 10.193.2.251 is no longer in use.

Thanks

I update Netbox

@Papaul thanks, just a small detail, I've deleted also the 'mgmt' interface from 'mw2231 old' ( https://netbox.wikimedia.org/dcim/devices/1185/ ) given that it's offline (unracked).

Forgot to mention that https://netbox.wikimedia.org/ipam/ip-addresses/687/ had still the old name, I've updated it.

@Volans Thanks
