DSS V7 Failover function description
Function: Failover Manager
The failover manager provides an overview of the cluster configuration and allows starting and stopping the cluster.
start
Start button is shown when the failover hasn't been started. Use it to start the failover process. When the configuration verification mechanism is finished without any errors and the failover is started, the virtual IP addresses are activated and the resources are available through the virtual IP address. After failover is started this button is replaced by the "stop" button.
stop
Stop button is shown when the failover is running. By clicking this button you can stop the failover process on both nodes. As a result the virtual IPs will deactivated. When the failover is stopped resources will be only available using physical IP addresses of the node where the resources are located.
Failover contains three sections: Resource pool, Configuration statuses and the Remote node status. Each of the section provides a general overview of the cluster configuration and the current state of services which are obligatory for the failover process. Each section contains a link to the part of the DSS V7 Web GUI where the services can be configured.
Resource pool
Displays the status of resources that are on the local and the remote node. It also shows the volume replication task state. The quick link forwards you to the resource pool manager.
Configuration statuses
Displays information about the amount of configured and available ping nodes and configured auxiliary paths. The quick links will forward you to the ping node configuration and to the auxiliary path configuration.
Remote node status
Displays the host name and the IP address of the remote node as well as information if the connection between the local and the remote node has been established.
The quick link will forward you to "Host binding" in "Configuration -> Volume manager -> Volume replication" on the local nodes.
