Registering and Configuring Sun Cluster HA for Netscape

After you have installed the Netscape Messaging Server 4.1 components, you must register the data service using the hareg(1M) command, and configure Sun Cluster HA for Netscape using the hadsconfig(1M) command and the parameters described in "Configuration Parameters for Sun Cluster HA for Netscape".

How to Register and Configure Sun Cluster HA for Netscape

Perform all steps from only one cluster node. You must have root privilege to register and configure the data service.

1. Register the data service by using the hareg(1M) command.

   Run the hareg(1M) command on only one node. To register the service only on the logical host, include the --h option and logical host name:

   # hareg -s -r nsmail [-h logicalhost]

2. Configure the data service by using the hadsconfig(1M) command.

   The hadsconfig(1M) command is used to create, edit, and delete instances of a Sun Cluster HA for Netscape data service. See the hadsconfig(1M) man page for details. See "Configuration Parameters for Sun Cluster HA for Netscape" for information on the input to supply to hadsconfig(1M).

   # hadsconfig

3. Use the hareg(1M) command to activate the data service:

   # hareg -y nsmail
