GWAVA fully supports Novell Cluster Services.

[edit]

First Node Installation

  • Proceed as instructed in Installing the GWAVA package. The application will be installed at /opt/beginfinite/gwava, and various symlinks and service scripts will be created. The programs will be running once the RPM is installed.
  • Stop the GWAVA programs by typing /etc/init.d/gwavaman stop
  • Move the /opt/beginfinite/gwava directory to your shared storage device.
  • Create a symbolic link (symlink) pointing to the new directory from /opt/beginfinite/gwava. For example, if the new location is /mnt/nss/groupwise/gwava, type ln -sf /mnt/nss/groupwise/gwava /opt/beginfinite.
  • Restart the GWAVA programs by typing /etc/init.d/gwavaman start

Subsequent Node Installations

Included in the GWAVAInstall.tar.gz is the cluster folder. Copy the contents to an accessible location (your shared storage, for example) and run NodeInstall.sh by clicking on it or by typing ./NodeInstall.sh from the command line while logged onto your secondary node server.

You will be asked for the location of the shared gwava directory, and will not be allowed to proceed without providing it.

TIP: The Node Install program checks to make sure that you have not installed GWAVA locally, and that the designated location is valid.

You'll then be presented with a two choice menu:

  • Install Node - Normally the administrator should simply select this option. It is rarely necessary to change the preconfigured selections.
  • Modify Options - Allows the administrator to toggle certain advanced operations. For example, by default, the INIT service script is copied to /etc/init.d, but not automatically registered. This is because you do not want all node servers running GWAVA services automatically upon reboot. However, this, along with other options, may be toggled.
NOTE: If you do not have your GroupWise binaries on a clustered resource, you will have to manually copy /opt/novell/groupwise/agents/bin/gwavamta.xml to other nodes if you install an MTA scanner.

Cluster scripts and ordering

After the Node Install program completes, you'll want to configure your cluster start and stop scripts to run /etc/init.d/gwavaman start and /etc/init.d/gwavaman stop respectively when a node is switched. Assign them a 2 minute timeout, and make sure GWAVA is run BEFORE Groupwise is run, and unloaded AFTER Groupwise is unloaded.
