In currently attribute Lock_Model_Name is applyed only for Device model but not for subcomponents or specific model types (for example Cluster Group). Even if we lock model name, after SpectroSERVER restarting or any model reconfiguration by Cluster Manager the system updated model name with user System_Generated.
And recorded event look like this one:
<!--1564643512000 237560669-->Aug 1, 2019 10:11:52 MSK The model name for model AIP-SM of type ClusterMSCSResourceGroup was changed by user System_Generated from Cluster Group AIP-SM-BUR to AIP-SM. AIP-SM 0x1a100 System_Generated ClusterMSCSResourceGroup 10
Need to be that attribute Lock_Model_Name have maximum priority and system was locked to update this model name.
