eqiad row C switches upgrade
For reasons detailed in T327248: eqiad/codfw virtual-chassis upgrades we're going to upgrade eqiad row C switches during the scheduled DC switchover.
Scheduled on April 4th - 13:00-15:00 UTC , please let us know if there is any issue with the scheduled time.
It means a 30min hard downtime for the whole row if everything goes well (well, 15min in real-reality). Also a good opportunity to test the hosts depool mechanisms and row redundancy of services.
The list of impacted servers and teams for this row is listed below.
The actions needed is quite free form:
- please write NONE if no action is needed,
- the cookbook/command to run if it can be done by a 3rd party
- who will be around to take care of the depool
- Link to the relevant doc
- etc
The two main types of actions needed are depool and monitoring downtime
NOTE: If the servers can handle a longer depool, it's preferred to depool them many hours or the day before (and mark None in the table) so there are less moving parts closer to the maintenance window.
All servers will be downtimed with sudo cookbook sre.hosts.downtime --hours 2 -r "eqiad row C upgrade" -t T331882 'P{P:netbox::host%location ~ "C.*eqiad"}' but specific services might need specific downtimes.
