Ping Nodes

A ping node is a pseudo-member of a failover. It is located outside of the failover and serves to answer ICMP requests from failover members. (this means the ping node cannot be either the primary or the secondary node). It is there to make sure the outside connection for the failover members remains online.

For instance, if the ICMP request from the active node to the ping node fails, a similar request is performed by the remote node. If this one succeeds, resources are moved from the active node to the remote note. Automatic failover will only take place if all ping nodes become unavailable for one of the active nodes (e.g. the server does not take action when at least one ping node is reachable). The ping node needs only to be able to receive and reply to ICMP echo requests.

add new ping node

pressing this button will expand the window and show an empty area to enter an IP address of a ping node. Pressing the button for the second time will add the enter IP address to the ping node list.

When a new IP address of a ping node is entered, the status for the ping nodes is automatically being verified on both nodes. As a result the status is shown for both the local node and for the remote node.
