Description
Observation¶
Starting 2023-04-27 15:15:00 the mentioned machines in the title failed to access/ping s390 LPARs. Something between these hosts has changed or broke and needs to be fixed.
We had similar issues in the past, see the following SD tickets:
- https://sd.suse.com/servicedesk/customer/portal/1/SD-92689
- https://sd.suse.com/servicedesk/customer/portal/1/SD-115963
Suggestions¶
- Check what these machines have in common. A quick look of mine showed that they are in the "old" qa network close by: https://racktables.suse.de/index.php?page=rack&rack_id=516
- Check if other machines in that location, network, room, switch have the same problems
- Create a new SD ticket referencing the old ones. Robert mentioned in one of them that we might need to get rid of a second uplink
Rollback steps¶
- Remove silence for rule_uid=2Z025iB4km
