## Symptoms

- * Security Gateway object is missing from 'GATEWAYS \& SERVERS' application in Multi-Domain view of R80 SmartConsole.

* *$MDS_TEMPLATE/log/cpm.elg* file on R80 Multi-Domain Security Management Server shows the following error:  
  `
  java.lang.RuntimeException: Failed to deserialize object '`*Name_of_Security_Gateway_Object* `' of class com.checkpoint.objects.classes.dummy.CpmiGatewayCluster. set: . Error: java.lang.RuntimeException: Failed to deserialize object 'No Name' of class com.checkpoint.objects.classes.dummy.CpmiIdentityAwareBlade. set: . Error: java.lang.RuntimeException: Failed to deserialize object 'No Name' of class com.checkpoint.objects.identity_awareness_classes.dummy.CpmiRadiusAccountingSetting. set: . Error: java.lang.IllegalArgumentException: com.checkpoint.management.coresvc.ObjectNotFoundException: Object not found - network_objects:`*Name_of_Network_Object*`_._._NB
  `

## Cause

There is a mirroring mechanism that allows objects that are created on the Domain level to be displayed in the MDS overview.

There is a list of fields that are being checked in the Domain's database once the MDS server starts.

The Security Gateway object contains some fields that are not included on this list.

Therefore, a mirror object was not created on the Domain, and the object was not displayed.
