DNS Configuration failover on AIX and Solaris

Hi,

Our AIX and Solaris box are configured to use DNS.  Our DNS is our Windows Active Directory.  I want to configure failover on our DNS.   For example, if the primary DNS Server (Active directory) fails, I want that back-up Domain controller to serve as a DNS server.

What are the configurations to be done on AIX and Solaris Servers?

Thanks

Since your Solaris and AIX boxes are DNS client, you can put
the DNS infor in the /etc/resolv.conf.

the file should looks like:
domain yourdomain
nameserver your-primary-dns-server-IP
nameserver your-2nd-dns-server-IP

I'd suggest using caching dns server on UNIX hosts to make changing DNS configuration change possible while system is running:

The one for Linux:

But you have to use "forwarders" instead of "root servers" and some system specific directories for BIND data files.
