You can restore a deleted host to the system configuration information on the basis of the deletion history of system configuration information. However, the host group, ID group, and inventory information for a deleted host are not restored.

You cannot restore a deleted host if there is no route during host deletion but the host was registered in the system configuration information. Also, in a system where multiple managing servers are configured in a hierarchy, you cannot restore a relay system or client under a relay manager from its higher manager.

Even if you restore a deleted host to the system configuration information, the host still remains in the deletion history in the Deletion History of System Configuration Information dialog box. You can delete this deletion history as necessary.

To restore a deleted host to the system configuration information:

1. Choose File, and then Deletion History of System Configuration Information.
   The Deletion History of System Configuration Information dialog box appears.
   
2. Select the host you want to restored, and then click the Restore button.
   The host is restored to the system configuration information.
   You can also select multiple hosts and restore them in the batch mode.
