Abstract
A method, system, and program product are provided. A plurality of recovery groups is defined on each transmission control protocol/internet protocol (TCP/IP) stack in a cluster of servers. The recovery group includes a service, one or more IP addresses associated with the service, a trigger condition, and a recovery action. Each of the recovery groups is monitored for an occurrence of the trigger condition associated with the service. In response to detecting the trigger condition, a backup TCP/IP stack is notified to automatically perform the recovery action defined for a failing recovery group on an owning TCP/IP stack. Only the failing recovery group is recovered and the remaining recovery groups execute uninterrupted.
