CheckMK Appliance Network not coming up

OS version: 1.7.0 (appliance)

Hey all,

we are currently setting up our second checkmk appliance hardware cluster and ran into a problem we could not solve. Maybe some here can give any helpful advice now.

Long story short: we preconfigured both nodes (names, ssh, webaccess, network and idrac) in the office and were able to connect to both nodes via webaccess. Now they were shipped to the datacenter and plugged in. Access via idrac is possible but the network access is not possible. In idrac we see the interfaces as up but the appliance os insists there are no active links. When we try to same the ip adresses again a short notice pops up “RTNETLINK answers: Cannot assign requested address“ and all interfaces are marked offline.

Is there anything we could do? Usually i would go to the cli and try to take a deeper dive but since we have only the limited os options and no real cli i have no more clues

Hi,

I would try to delete the config and restart the system, after the restart I would try to configure the system new. :slight_smile:

Hi,

We solved the issue via our Appliance Support. Issue was because the IP settings were assigned to the first network interface eno1. Since we did not use copper in the datacenter in favor of fibre we needed to change the configuration in /etc/network/interfaces and replaced both “eno1” entries with the correct fibre interface “eno12399”. After this change and a system reboot the access via webconf was possible.
