IPs are not linked between devices as links are made at layer 2 (LAN Endpoints).
LAN Endpoints aren't usually modelled from end to end either but are related to Connectivity Segments. Your discovery is doing the right thing by assuming that the IPs are unique and relating them to their parent computers (via weak relationships that would preclude an IP having more than one parent with the normal Hosted Access Point relationship). ADDM uses a dependency relationship between the two computers to indicate that they are connected. HTH Cheers Peter From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Jason Alexander Sent: 11 February 2011 17:02 To: [email protected] Subject: Question regarding a CMDB concept ** Hi, CMDB v2.1 Topology Discovery 1.6 Remedy v7.1 Scenario: Assume that Hosts 'A' and 'B' are connected/linked to the same IP End Point 'C'. These are being discovered by Topology Discovery. Per my understanding, within the Topology Dataset in CMDB, there should be 1 CI corresponding to 'A' in the BMC_ComputerSystem Class, 1 CI corresponding to 'B' in the BMC_ComputerSystem Class and 1 CI corresponding to 'C' in the BMC_IPENDPOINT class and 2 entries in the BMC_Base Relationships class (1 relationship between A and C, and 1 between B and C) However, it turns out that there are 2 instances of the 'C' CI in the Topology Discovery Dataset and 1 instance of the 'C' CI is linked to 'A' and another instance of the 'C' CI is linked to 'B'. Is there something that I am not understanding here? I was thinking that a CI should be unique, so there should be only one instance of 'C' (and not 2) in the Topology dataset (IPENDPOINT class). Can somebody please clarify the concept for me? -- Thanks, Jason _attend WWRUG11 www.wwrug.com ARSlist: "Where the Answers Are"_ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org attend wwrug11 www.wwrug.com ARSList: "Where the Answers Are"
