After Upgrade the UIM 23.4CU1, Where do the reappearing deleted devices come from? They don't exist, not even in VMWare! Device have been decommissioned years ago, so how can they come back in the inventory? "
UIM 23.4 CU1
It came from niscache.These devices info will be maintained in cm_computer_system table,due to that when you rediscover it will reappear.
