Summary
Error
Before upgrading, there are some changes in %NnmInstallDir%\misc\nnm\props\shared\nms-disco.properties file, like below:
#!com.hp.ov.nms.disco.suppressFDBconnections=false
com.hp.ov.nms.disco.suppressFDBconnections=true -------> added line
but after upgrading from NNMi v9.1x to NNMi9.2x, previous changes was disappered, just only below line was left:
#!com.hp.ov.nms.disco.suppressFDBconnections=false
%NnmInstallDir%: <drive>\Program Files (x86)\HP\HP BTO Software
%NnmDataDir%: <drive>\ProgramData\HP\HP BTO Software
Cause
In Network Node Manager (NNMi), we can see nms-disco.properties file in the two places:
NnmInstallDir/misc/nnm/props/
NnmDataDir/shared/nnm/conf/props
but these two places have different role for property files.
for NnmInstallDir/misc/nnm/props/ directory, the customer should never change configuration
parameters in NnmInstallDir/misc/nnm/props - in fact they should never be aware that this directory even exists.
These files will get overwritten with each new NNMi product release.
Fix
We should change nms-disco.properties file which located in NnmDataDir/shared/nnm/conf/props
NOT NnmInstallDir/misc/nnm/props/.
