Installing the Tiebreaker software

The Tiebreaker software provides monitoring capabilities for a clustered storage environment. It also sends SNMP notifications in the event of node connectivity issues and site disasters.

Before you begin

The MetroCluster software must be installed and configured.

System requirements for installing or upgrading Tiebreaker software
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.
Installing MetroCluster Tiebreaker dependencies
You must install a MySQL or MariaDB server depending on the Linux operating system that is your host before installing or upgrading the Tiebreaker software.
Installing or upgrading the software package
You must install or upgrade the MetroCluster Tiebreaker software on your local computer to monitor MetroCluster configurations.
Upgrading the host where the Tiebreaker monitor is running
You can upgrade the host where the Tiebreaker monitor is running with minimal disruption if you place the monitors in observer mode before the upgrade.
Selecting the NTP source for the Tiebreaker software
You should use a local Network Time Protocol (NTP) source for the Tiebreaker software. It should not use the same source as the MetroCluster sites that the Tiebreaker software monitors.
