How to Install and Configure Quorum Server Software

Perform this procedure to configure a host server as a quorum server.

Before You Begin

Perform the following tasks:

• Ensure that you are registered with pkg.sun.com and that the machine to install has the necessary setup to download packages. See How to Prepare to Download Open HA Cluster Software.

• Ensure that the machine that you choose for the quorum server has at least 1 Mbyte of disk space available for Quorum Server software installation.

• Ensure that the quorum-server machine is connected to a public network that is accessible to the cluster nodes.

• Disable the spanning tree algorithm on the Ethernet switches for the ports that are connected to the cluster public network where the quorum server will run.

1. Become superuser on the machine to install with Quorum Server software.

   Alternatively, if your user account is assigned the Primary Administrator profile, execute commands as non-root through a profile shell, or prefix the command with the pfexec command.

2. Install the Quorum Server package.

   quorumserver# /usr/bin/pkg install ha-cluster-quorum-server-full

3. (Optional) Add the Quorum Server binary location to your PATH environment variable.

   quorumserver# PATH=$PATH:/usr/cluster/bin

4. (Optional) Add the Quorum Server man-page location to your MANPATH environment variable.

   quorumserver# MANPATH=$MANPATH:/usr/cluster/man

5. Configure the quorum server.

   Add the following entry to the /etc/scqsd/scqsd.conf file to specify configuration information about the quorum server.

   Identify the quorum server by using at least one of either an instance name or a port number. 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 an instance name, always refer to this quorum server by the port on which it listens.

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

   -d quorumdirectory

   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.

6. (Optional) To serve more than one cluster but use a different port number or instance, configure an additional entry for each additional instance of the quorum server that you need.

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

8. Start the newly configured quorum server and its SMF service.

   quorumserver# svcadm enable svc:/system/cluster/quorumserver:default

Next Steps

If you will use virtual network interfaces (VNICs) in the cluster private interconnect and want to preconfigure the VNICs, go to How to Create a Virtual Network Interface (VNIC). You can alternatively create VNICs during cluster configuration by running the scinstall utility in Custom Mode.
