OK I have resolved this issue. As it turns out the virtual center SSO bug was preventing the needed communication. The error itslef is discussed in this vmware thread. Exception thrown by SsoUtil: SSO admin service ... | VMware Communities  This issue can show up in vCenter 6.0u1 and u1. The fix will come out in the next patch for vCenter server.  As an immediate workaround you can reboot the psc or vcenter and immediately re-run the failed tasks.
I'm attempting to deploy ScaleIO 2.0.0.2 on vSphere 6.0u2 and keep getting this error when attempting to deploy. I have reviewed this post for network validation. Deploy Scale IO error Configure SDC driver on ESX  I'm able to ping the SVM data IP from the ESXi data vmk. Same with the management vmk to the management IP of the SVM. Re-registered the plugin and rebooted hosts a number of times. Can somebody help me understand the exact traffic flow involved with this error?  Failed: Configure SDC driver on ESX (The SDC cannot communicate with the MDM cluster. Verify vmkernel and/or portgroup settings. )  Are there options for getting a bit more logging detail? I looked at doing this step with scli and found that the scini parameters are already configured with the primary & secondary MDM IP addresses which are correct. Any other suggestions for resolving this issue?   Thanks, Blake
