A switchable IP address is a “virtual” IP address that can be switched between servers. It is separate from the IP address associated with the network interface card of each server. Applications under LifeKeeper protection are associated with the switchable IP address. Then, if there is a failure on the primary server, that IP address “switches” to the backup server.

If you plan to configure resource hierarchies for switchable IP addresses, you must do the following on each server in the cluster:

  • Verify that the computer name is correct and will not be changed.
  • Verify that the switchable IP addresses are unique using the ping command.
  • Edit the /etc/hosts file to add an entry for each switchable IP address.

Refer to the LifeKeeper for Linux IP Recovery Kit Technical Documentation for additional information.
