HAF automatically polls the HMC/SE workstations that you have selected to detect whether a target HMC/SE can be reached and whether it will respond to a simple request for information. HAF reports when an HMC/SE is inaccessible or hung.
Using the same HMC console API, HAF is designed to be used in conjunction with the APCMOSI REXX program. Although HAF can only passively receive broadcasted messages from selected HMC/SE workstations, you must use the APCMOSI REXX program to issue commands to targeted HMC workstations.
When HAF and the APCMOSI REXX program operate under the control of the Automation Point Desktop, HMC automation can be written to correlate or interact with other defined sessions on the Automation Point Desktop. Messages received by HAF are displayed on the Automation Point Desktop in a session window named HAF_Events and automatically sent through CA Automation Point rules engine for processing. Therefore, you can write CA Automation Point rules to detect a HMC generated status message or event, and react by invoking APCMOSI to issue a predetermined HMC console command.
