I installed a new 8.2.1 CDOT system. I upgraded it from 8.2.1 7 mode. At first all the nodes worked on the network properly. Then I rebooted node 1 and I could not ping the node management ports from remote site anymore. I got on the SP and everything looked fine.
I rebooted again and got these messages
route: writing to routing socket: Network is unreachable add net 0.0.0.0: gateway 10.26.6.1: Network is unreachable Apr 25 16:35:23 Battery charge capacity: 3584 mA*hr. Power outage protection flash de-staging cycles: 54
It won't add the default gateway on boot up. I can't ping the eom management ports on each node. But, this, is the strange part, I can ping the cluster management IP on the same management network.
Does anyone have any idea why it won't add the default gateway when it boots?
If you want cluster_mgmt LIF be on e0i interface, this interface should be connected to the 10.28.8.60/24 network (broadcast domain, VLAN, however it is called by your networking equipment). But my guess is that you simply need to create failover group for cluster_mgmt LIF that consists of e0M ports on all nodes.
Anyway right now you just need to move cluster_mgmt LIF to e0M port to get access again.
