Network config issues in OVA image

[remedsys]

I recently downloaded and installed the latest OVA image of NagiosXI on one of our ESXi hosts. I tried to add a second NIC to the server in order to monitor some hardware on our storage network, and now I cannot get the network interface to come back up.

Originally NagiosXI was grabbing an IP from our DHCP server, but now it won't, even if I set it to DHCP. When I try to set a static IP, I'm also unable to access the server.

I've tried removing and re-adding the NIC in vSphere, but that did nothing.

When I try to ifup <interface> I get the following:

Code: Select all

Error: Connection activation failed: IP configuration could not be reserved (no available address, timeout, etc.)

I've attached a screenshot of the config from /etc/sysconfig/network-scripts

This doesn't seem like a nagios issue... What is the IP address that you are using, when trying to access Nagios XI? What is the output of the commands below?

Code: Select all

service network restart
ip addr

You may try to comment out the old entries in /lib/udev/rules.d/75-persistent-net-generator.rules and/or /etc/udev/rules.d/70-persistent-net.rules and restart the VM to see if this is going to fix the issue.
