Chapter 6 Group resource details 522 • Machines that can resolve the path information of a virtual IP address by accessing a router. � Cluster servers that belong to a different LAN that the server the virtual IP activates belongs to Virtual IP addresses can be used if the following condition is satisfied: • Machines that can resolve path information of the virtual IP address by accessing a router. � Clients that belong to the same LAN that cluster servers belong to Virtual IP addresses can be used if the following conditions are satisfied: • Machines that can change the path by receiving RIP packets. • Machines that can resolve the path information of a virtual IP address by accessing a router. � Clients on the remote LAN Virtual IP addresses can be used if the following condition is satisfied: • Machines that can resolve path information of the virtual IP address by accessing a router. Notes on IP resources Virtual IP addresses do not support NetBIOS protocol. � Even if you map a virtual IP address to a host name using LMHOSTS, it cannot be used for accessing and user authentication for Windows browsing, networks, and printer resources. � Use a virtual computer name to automatically switch the connection destination with the NetBIOS protocol. The following rule applies to virtual IP addresses. � The number of a virtual IP resource to be registered on one cluster system is up to 64. � To use a virtual IP resource, the names of a cluster, server and group need to be set according to the naming rules of Ver8.0 or earlier. Adjust the value of the flush timer of the router within the value for heartbeat timeout. See “Timeout tab” in “Chapter 3 Function of the Builder” for details on heartbeat timeout.
