Products

Issue/Introduction

When attempting to access the Aria Operations Admin page or UI, you might encounter an error: can't reach this page

 

Environment

VMware Aria Operations 8.x

Cause

This issue can occur when the gateway IP address is missing from the configuration file of Aria Operations node

 

Resolution

To resolve the issue, configure gateway IP address on the NIC by following the steps mentioned below:

Note: Before modifying the 10-eth0.network file, please ensure the following points are verified:

• Verify if the gateway IP is correctly mentioned in the vApp Options within the vSphere client for the Aria Operations VM. For more information on how to access virtual machine's vApp Options, click here
• Verify if the gateway IP is present in the /opt/vmware/etc/ovfEnv.xml file of the Aria Operations VM.

Update the gateway IP address by editing the config file /etc/systemd/network/10-eth0.network:

• Take backup of the configuration file /etc/systemd/network/10-eth0.network
• SSH to the VMware Aria Operations nodes as root
• Check Gateway IP: route -n

If the gateway IP address is not listed in the result, proceed to the next step.

• Using a text editor, open network configuration: vi /etc/systemd/network/10-eth0.network
  
  Update the gateway IP address under the [Network] section.

For example:
[Network]
Gateway=X.X.X.X

• Save and exit the file
• Run the following commands to apply the changes:

ifdown eth0

ifup eth0

• Repeat step 1 to 6 on all nodes in the cluster in case if gateway IP address is missing
• After making the changes, verify the network settings again using the command "route -n" to ensure the gateway IP is correctly listed
