This error occurs during rediscovery of a system when no IP address object exists in the topology for an SNMP agent, or each IP address that is associated with the SNMP agent is one of the following:

  • An unmanaged IP address

  • An IP address within the range of the ipExcludeList parameter in the discovery.conf file

  • An IP address that is associated with an interface that is either in BACKUP or ONDEMAND mode

    Because the IP Manager has no valid IP address to access the SNMP agent, it notifies a DiscoveryError.
