DNS Clients

In Solaris, a host that is a client of DNS has an /etc/resolv.conf file. The file lists name server hosts to contact for DNS service. The name server hosts are listed as IP addresses rather than host names. More than one host IP address might be listed.

Network clients of HA-in.named would list the IP address of the logical host, for example, that of hahost1, in the /etc/resolv.conf file.

There are periods when a physical host does not master the logical host that HA-in.named uses. However, the host must have the ability to be a client of HA-in.named during those periods. To achieve this, add the IP address of the logical host to the /etc/resolv.conf file on all physical hosts of the cluster.
