Additional requirements
You must be aware of the following additional requirements:
-
The Tiebreaker software is installed on a third site, which allows the software to distinguish between an inter-switch link (ISL) failure (when inter-site links are down) and a site failure. Your host system must meet certain requirements before you can install or upgrade the Tiebreaker software on your local computer to monitor the MetroCluster configuration.
-
You must have "root" privileges to install MetroCluster Tiebreaker software and the dependant packages.
-
You can only use one MetroCluster Tiebreaker monitor per MetroCluster configuration to avoid any conflict with multiple Tiebreaker monitors.
-
