Hi Sam.
I checked the Event Log on NX3500, but is not possible export the LOG.
How to do to export the LOG for you ?
Follow below the Event Viewer Information:
Service add_luns-pair-0 was declared as failed on node0
Action Items: Service failure can be declared by either the service or by the monitoring system upon failure in sampling the service.
Search the events log for events issued by the failing service to pinpoint the cause of failure.
