Symptoms


The deploymanager.log under (/usr/local/avamar/var/log/vcs/deploymanager.log) on Avamar server shows the following error message :

If proxy is deployed manually to test and we run vami_config_net script to manually assign the IP, the following error is seen:

Eth0 device-ready 
Eth0 device-not-running 
ERROR Network failed to restart using new parameters for eth0 (Errno 2: ) 
ERROR attempting to restore network values for eth0 to previous settings 
Eth0 device-not-running 
Cause
This issue can occur if a Duplicate IP address is being used for the new Avamar Proxy causing the issue. Avamar Proxy runs SUSE OS and by design it will shutdown the ethernet interface if it detects a Duplicate IP address. 
Resolution
In order to confirm a duplicate IP address is assigned, perform the following steps :

1: Confirm that port 5489 is open from Avamar Utility node to the new proxy on the firewall.
Note: The Forward and reverse lookup entries should be created for the proxy in the DNS servers to avoid proxy deployment failure due to hostname not assigned. 

2: Perform a ping test to the Avamar Proxy IP to confirm if you get a reply on the same. (It maybe better to perform the test on a machine running on the same network/subnet as the proxy server)

ping <Avamar_Proxy_IP>

If you get a response back, this confirms that this is a duplicate IP address. 
A few additional tests can be done using arping command :

arping -D <Avamar_Proxy_IP> -c 3 
echo $?


If we get a echo reply as 0, this will confirm the IP address is duplicate. 

3: Use a different static unused IP address for this proxy and test the deployment to confirm the issue is resolved.
