KB00004: Wrong items deployed on a secondary UC or LM PLC node
EVA ICS versions: 3.0.0 and above
Problem
Wrong items were accidentally deployed on the secondary node.
Solution
The best solution is to undeploy all the items with the same configuration they were deployed:
eva sfa cloud undeploy -y deploy.yml
however sometimes the deployment file may be unavailable or the undeployment process could take a long time.
The solution is to manually delete items from controllers.
Items can be filtered by group
On the secondary controllers, execute:
eva uc destroy -g GROUP # delete BOTH units and sensors
eva lm destroy -g GROUP # delete lvars only
Item can not be filtered by group
If items can not be filtered by group or there are special items, like LM PLC macros, cycles etc., stop the controller and use the system shell to manually delete item configuration files / keys using a preferred way.
On the secondary controllers, execute.
For EVA ICS 3.3.2 and below:
eva uc server stop
cd /opt/eva/runtime
# uc_unit.d - the directory with unit configuration files
# uc_sensor.d - sensors
eva uc server start
eva lm server stop
cd /opt/eva/runtime
# lm_lvar.d - lvars
# lm_dmatrix_rule.d - decision rules
# lm_job.d - scheduled jobs
# lm_lcycle.d - cycles
# lm_lmacro.d - macros
eva lm server start
For EVA ICS 3.4.0 and above:
eva lm server stop
eva uc server stop
eva registry manage
# delete all items
# individual items / group keys can be also deleted as well
delete -r eva3/<hostname>/inventory
eva uc server start
eva lm server start
