Background Information
RightLink 10 is the latest of the RightLink Agent family and its built totally from scratch. Being different from the previous version, during the restart of the agent, the process triggers the decommission (decom) sequence. If you don't want this behavior, follow the steps below.
Answer
You may skip the decom sequence by putting the following line on top of any of your decommission scripts.
[[ $DECOM_REASON != "terminate" ]] && echo "Server is not terminating. Skipping." && exit 0
If you desire to use the script as ad-hoc, you can try the following:
if ([ ! -z "$DECOM_REASON" ] && [ "$DECOM_REASON" != 'terminate' ]); then
echo 'server is not terminating, skipping.'
exit 0
fi
