When Spectrum is integrated with Unified Infrastructure Manager (UIM), you may notice that in OneClick if you click on Nimsoft Manager -> Virtualization -> Vmware -> <vcenter server name> the Topology tab in the Contents pane reports the following error:
SPC-OCC11681: Unable to render topology.
Ideally we do not display any contents here as the model does not support a topological view. The topology tab should be disabled by default for this view. This is a known issue which is fixed in Spectrum via patch PTF_184.108.40.206 (Should be applied on Spectrum version 220.127.116.11) and is included in versions 9.4.3 or 10.1.
Please contact CA Support if you need any further clarifications.
