12.2.1 How to Install and Configure Sun Cluster HA for DNS

Once you have installed Sun Cluster and DNS, follow the procedures described in this section to install, configure, register, and activate Sun Cluster HA for DNS.

1. On each Sun Cluster server, install the SUNWscdns packages in the default location.

   If not already installed, use the pkgadd command to install the SUNWscdns package on each Sun Cluster server.

2. Run the hadsconfig(1M) command to configure Sun Cluster HA for DNS.

   The hadsconfig(1M) command is used to create, edit, and delete instances of a Sun Cluster HA for DNS data service. Refer to "12.2.2 Configuration Parameters", for information on the input you will need to supply to the hadsconfig(1M)command.

   phys-hahost1# hadsconfig

3. Set Up HA-DBMS for ORACLE7.

   HA-DBMS for ORACLE7 is required to run the HA-COMMUNITY data services.

   Follow the instructions in Chapter 5, Setting Up and Administering Sun Cluster HA for Oracle.

4. Register the Sun Cluster HA for DNS data service by running the hareg(1M) command.

   If you installed Sun Cluster HA for DNS on all potential masters of a logical host but not on all hosts in the cluster, use the -h option to specify the logical host name. Run the hareg(1M) command on only one node.

   phys-hahost1# hareg -s -r dns [-h logicalhost]

5. Use the hareg(1M) command to enable the Sun Cluster HA for DNS data service and perform a cluster reconfiguration.

   Run the hareg(1M) command on only one node.

   phys-hahost1# hareg -y dns

   The configuration is complete.
