Scripts to run with high availability

The following sample script can be used:
highAvailChange
The HighAvailChange script runs whenever the high availability state changes within the Load Balancer. You can create this script to use state change information, for instance, to alert an Administrator or simply record the event.

[Linux] On Linux for s/390: Load Balancer issues a gratuitous ARP to move IP addresses from one Load Balancer to another. This mechanism is therefore tied to the underlying network type. When running Linux for s/390, Load Balancer can natively do high availability takeovers, complete with IP address moves, only on those interfaces which can issue a gratuitous ARP and configure the address on the local interface. This mechanism will not work properly on point-to-point interfaces such as IUCV and CTC and will not work properly in certain configurations of qeth/QDIO.
