Update DNS configuration on an Avamar Proxy

A common cause of VM backup failures is DNS servers changed, but was not updated on the proxy. Do update the DNS config without having to redeploy the proxy:

1. Log in to the proxy as admin
2. Switch to root user

su -

1. Check the current configuration

cat /etc/resolv.conf

1. Use the following syntax.  x.x.x.x is the first DNS and y.y.y.y is the second DNS (optional)

/opt/vmware/share/vami/vami_set_dns -s yourdomain.com  x.x.x.x    y.y.y.y

1. Reboot the proxy and confirm the change persists

reboot

cat /etc/resolv.conf
