Error description
We have a problem with alerts getting generated for DS6800 that is tagged on to the TPC. We have probes running for this subsystem every hour and data path missing alerts are generated every hour for the same set of volumes and same set of hosts that are tagged to DS6800. The DS6800 does not have any changes done on the volume or hosts between two consecutive probes and still the same set of alerts are generated every hour.
