13.3.1 How to Install and Configure Sun Cluster HA for Lotus

1. On each Sun Cluster server that will be running HA-Lotus, run the hadsconfig(1M) command to configure Sun Cluster HA for Lotus.

   Use the hadsconfig(1M) command to create, edit, and delete instances of Sun Cluster HA for Lotus. Refer to "13.3.2 Configuration Parameters for Sun Cluster HA for Lotus", for information on the input you will need to supply to the hadsconfig(1M) command. See the hadsconfig(1M) man page for details.

   # hadsconfig

   ---

   Caution -

   Configure only one Lotus instance per cluster. Activation of Lotus instances is "all or nothing", that is, you cannot activate only a subset of instances in a cluster. Therefore, multiple instances can conflict with each other.

2. Register and activate Sun Cluster HA for Lotus using the hareg(1M) command.

   The hareg(1M) command adds the Sun Cluster HA for Lotus data service to the Cluster Configuration Database, performs a cluster reconfiguration, and starts all of your Lotus Domino servers. Run this command on only one node:

   # hareg -s -r lotus ... # hareg -y lotus

3. Verify the Sun Cluster HA for Lotus configuration.

   Log in as notes and verify the configuration by starting and stopping the Lotus Domino server on one of the Sun Cluster servers:

   phys-hahost1# /opt/lotus/bin/server ... phys-hahost1# /opt/lotus/bin/server -q

   You can test more of the configuration by starting the cluster, mastering the logical hosts from various physical hosts, and then starting and stopping the Lotus Domino server from those physical hosts. For example:

   phys-hahost1# scadmin startcluster phys-hahost1 clustername phys-hahost2# scadmin startnode clustername phys-hahost1# haswitch phys-hahost2 hahost1 hahost2

   Log in as user notes, and stop and start the Lotus Domino server from the Domino data directory. For example:

   phys-hahost2# cd /hahost1/domino_data_dir phys-hahost2# /opt/lotus/bin/server ... phys-hahost2# /opt/lotus/bin/server -q

   This completes the configuration and activation of Sun Cluster HA for Lotus.
