Resolution

When a power-on reset (POR) is performed to load a new IODF and HISRV is running.
The HIS Topology Collection functionality to respond to hardware changes was not built into the HISRV : HARDWARE INTERFACE SERVICE.
 
This causes the following error messages: 
 
For deleted hardware:
NKAG81 (FOLLOWING $HWBE), UNREC BCPII EVENT CODE/SUBCODE. VALUES: 3 6
 
For added hardware:
NKAG81 (FOLLOWING $HWBE), UNREC BCPII EVENT CODE/SUBCODE. VALUES: 3 5
 
The $HWBE dump following the NKAG80 message shows the name of the hardware element that was deleted or added.
 
CA recommends to restart the HISRV : HARDWARE INTERFACE SERVICE to read the new changes and establish a correct topology.
