You might have imported 'Foreign LUN Import' pack from store. This pack needs lun_import_ext table in OCUM ocum_data_collector database. Do you really need this pack ?
You need to deploy the data-collector_lun_import_ext.conf config file into OCUM. For more details, please read the help content of 'FLI Setup And Import' workflow under workflow--> help content --> view help content --> Before you begin section. There is a link to access the config file.
