Components

The HAFO product has multiple components:

• System Boot Failover Initialization Utility

• SYSGEN HAFO commands
• HASTAT HAFO status report
• HAFOCONF configuration file
Each of these components are briefly described.
System Boot Failover Initialization Utility
During system boot, the HAFO configuration utility reads the HAFOCONF
configuration file and arms HAFO. This configuration information is then
frozen into memory and is accessible to the MPE/iX I/O subsystems when a
HAFO event is detected.

configuration file
