This chapter describes how to install and remove the Sun Cluster Quorum Server software. It contains the following topics:
You can install the quorum server software on any computer connected to your cluster through the public network. The quorum server should not run on a cluster node.
The Sun Cluster Quorum Server software requires at least 1 MB disk space for its installation. The installation is independent of other Sun Java Enterprise System components. The Sun Cluster Quorum Server software does not depend upon the installation of the Java Enterprise System shared components nor upon the installation of the Sun Cluster core software or its agent software.
When using a quorum server, disable the spanning tree algorithm on the Ethernet switches for the ports connected to the cluster public network where the quorum server will run.
Become superuser on the host server to install.

Root access is required for installation.
(Optional) To use the installer program with a GUI, ensure that the display environment of the host server to install is set to display the GUI.
# xhost + # setenv DISPLAY nodename:0.0 |
Load the installation media into the drive.
If the volume management daemon (vold(1M)) is running and is configured to manage CD-ROM or DVD devices, the daemon automatically mounts the media on the /cdrom/cdrom0/ directory.
Change to the installation wizard directory of the media.
If you are installing the software packages on the SPARC platform, type the following command:
phys-schost# cd /cdrom/cdrom0/Solaris_sparc |
If you are installing the software packages on the x86 platform, type the following command:
phys-schost# cd /cdrom/cdrom0/Solaris_x86 |
Start the installation wizard.
phys-schost# ./installer |
Follow instructions on the screen to install the quorum server software on the host server.
Choose the Configure Later option.
If the installer does not allow you to choose the Configure Later option, choose Configure Now. You will still need to configure the quorum server by following the instructions in Chapter 2, Configuring the Sun Cluster Quorum Server Software.
After installation is finished, you can view any available installation log. See the Sun Java Enterprise System 2006Q4 Installation Guide for UNIX for additional information about using the Java Enterprise System installer program.
Unload the installation media from the drive.
Apply any necessary patches to support the quorum server software.
See Patches and Required Firmware Levels in Sun Cluster 3.2 Release Notes for Solaris OS for the location of patches and installation instructions.
Add the quorum server binary to your PATH environment variable.
# PATH=$PATH:/usr/cluster/bin |
Add the quorum server man pages to your MANPATH environment variable.
# MANPATH=$MANPATH:/usr/cluster/man |
The installer performs a simple pkgadd installation of the Sun Cluster Quorum Server packages and sets up the necessary directories. The software consists of the following packages:
SUNWscqsr
SUNWscqsu
SUNWscqsman
The pkgadd of these packages adds software to the /usr/cluster and /etc/scqsd directories. You cannot modify the location of the Sun Cluster Quorum Server software.
If you receive an installation error message regarding the quorum server, verify that the packages were properly installed.
If your system requires only the default quorum server, start the quorum server by following the instructions in How to Start a Quorum Server.
If your system requires a specially configured quorum server, or requires multiple quorum servers, configure quorum servers by following the instructions in Configuring Multiple Quorum Servers on the Same Host.
Before performing the uninstallation of the quorum server software, ensure that you have completed the following:
On each cluster, unconfigure any quorum server quorum devices configured for the quorum server being removed, by performing the steps in How to Remove a Quorum Device in Sun Cluster System Administration Guide for Solaris OS.
In normal operation, this step also removes the quorum server information on the quorum server host. If communications between the cluster and the quorum server host are down during this step, you must clean up the invalid quorum server information on the host. Perform the steps in Cleaning Up Stale Quorum Server Cluster Information to accomplish this cleanup.
On each quorum server host computer, stop the quorum server by following the steps in How to Stop a Quorum Server.
(Optional) To use the interactive graphical interface to uninstall the Java Enterprise System components, ensure that the display environment of the host server to uninstall is set to display the GUI.
% xhost + % setenv DISPLAY nodename:0.0 |
Become superuser on the host server to uninstall.
Root access is required for software removal
Navigate to the directory where the uninstaller is located:
phys-schost# cd /var/sadm/prod/SUNWentsysver |
The version of Java Enterprise System installed on your system.
Start the installation wizard.
phys-schost# ./uninstall |
Follow instructions on the screen to uninstall the quorum server software on the host server.
After removal is finished, you can view any available log. See the Sun Java Enterprise System 2006Q4 Installation Guide for UNIX for additional information about using the Java Enterprise System installer program.
(Optional) On each quorum server host computer, clean up or remove the quorum server directories.
By default, this directory is /var/scqsd.
