21.28 Configuring NNMi to retry ICMP pollings even if Destination Unreachable is received

If NNMi receives ICMP Destination Unreachable when performing status polling on a monitored node, NNMi judges that communication is not possible and does not retry ICMP polling.

If you want to continue retry ICMP polling even if Destination Unreachable is received, do the following:

1. Edit the following file:

   • Windows: %NNM_PROPS%\nms-communication.properties

   • Linux: $NNM_PROPS/nms-communication.properties

2. Search for the text block containing the following line:

   #!com.hp.ov.icmp.allowRetryIcmpIfDestinationUnreachable=false

3. Uncomment and edit this line to read as follows:

   com.hp.ov.icmp.allowRetryIcmpIfDestinationUnreachable=true

4. Save the nms-communication.properties file.

5. Restart NNMi by running the following commands:

   ovstop
   ovstart
