The installer displays the following error message if the installer cannot find the uuidconfig.pl script before it configures the UUID for the cluster:
Couldn't find uuidconfig.pl for uuid configuration, please create uuid manually before start vcs
You may see the error message during VCS configuration, upgrade, or when you add a node to the cluster using the installer.
Workaround: To start VCS, you must run the uuidconfig.pl script manually to configure the UUID on each cluster node.
