Sun Cluster Quorum Server User's Guide

Configuring Multiple Quorum Servers on the Same Host

You can add multiple quorum servers to the configuration file on a single host machine. Edit the /etc/scqsd/scqsd.conf file and add one entry for each additional instance of the quorum server that you need.

Lines that begin with the number sign (#) are treated as comments and ignored. Every line is executed as specified in the file.

ProcedureHow to Add a Quorum Server to the Configuration File

  1. Become superuser on the host where the Sun Cluster Quorum Server software is installed.

  2. Edit the /etc/scqsd/scqsd.conf file.

    Identify the quorum server by using at least one of either an instance name or a port number.


    /usr/cluster/lib/sc/scqsd [-d /var/scqsd] [-i instancename] -p port
    -d /var/scqsd

    The path to the directory where the quorum server can store quorum data.

    The quorum server process creates one file per cluster in this directory to store cluster-specific quorum information.

    By default, the value of this option is /var/scqsd. This directory must be unique for each quorum server that you configure.

    -i instancename

    A unique name that you choose for the quorum server instance.

    -p port

    The port number on which the quorum server listens for requests from the cluster.

    You must provide the port number, but the instance name is optional. If you provide an instance name, that name must be unique among your quorum servers. If you do not provide a name, always refer to this quorum server by the port on which it listens.

  3. Save and close the /etc/scqsd/scqsd.conf file.

  4. Start the newly configured quorum server. 


    # /usr/cluster/bin/clquorumserver start quorumserver
    quorumserver

    Identifies the quorum server. You can use the port number on which the quorum server listens. If you provided an instance name in the configuration file, you can use that name instead.

    To start a single quorum server, provide either the instance name or port number. To start all quorum servers, when you have multiple quorum servers configured, use the + operand.
