I have the same issue, did you have any luck with getting it?

No, we logged a call with Dell, but still do not have an answer for the problem.

there is no script for configuring SMI-S in the newer version of Dell Storage Manager. In the old version you needed to configure SMI-S using PowerShell, but that is not needed any longer

I have the same problem with the DSM-Data Collector, i was unable to connect them to the monitoring tool.

You mean that we no longer need to add the user to the SMI-S service?

?

Yes, you still need to create a user for SMI-S to work. Refer to page 13 of the Dell EMC SC Series Storage and SMI-S Integration with Microsoft SCVMM
http://en.community.dell.com/techcenter/extras/m/white_papers/20438128

On that page it states - Note: DSM 2016 R3 is featured in this guide. Data Collector versions prior to DSM 2016 R1 require extra configuration steps (automated with PowerShell). See appendix B for details.

SMI-S has only been tested on SCVMM per page 331 of the Dell Storage Manager 2016 R3 Administrator’s Guide

Storage Manager SMI-S is compatible with the following combinations of Microsoft System Center Virtual Machine Manager (SCVMM) 2012 and Microsoft Server versions.

Thank you very much for that document.  That was very helpful.  However I am now stuck at the SCVMM portion.  When I attempt to add, I am getting this error:

Could not retrieve a certificate from the IP ADDRESS REMOVED server because of the error: The request was aborted: Could not create SSL/TLS secure channel.

Specify a valid server name and port.

ID: 20909
Details: Unknown error (0x194).

I have tried regenerating the Certificate (Self-Sign) on the Storage Center, but it does not seem to correct the issue.  Also want to clarify I am connecting to the IP ADDRESS of the Server running Data Collector correct (and not the Management IP of the Storage Array)?

You want to establish the connection to the Data Collector and not the Storage Center. You want to create an SMI-S user in DSM per page 13, and per page 16 a matching SMI-S Run As account must be configured on the SCVMM server in order to do storage discovery. To be consistent, the Run As account is named smis and uses the same password as the smis user configured on the Data Collector.

I ran an advanced find and show a case which was open for the same error. Summary of issue with same error message:
Initially we found that NTP to be offset by -32866 on CVM. Resolved that by running script fix_time_skew.py to sync back the time

Then we were unable to add SMI-S Storage provider to 2016 SCVMM.

We made sure DNS is configured on cluster.

Installed intermediate certificates on both the VMMs

Instead of adding storage via GUI ran script via cli via command "setup_hyperv.py setup_scvmm"

That resolved the issue.

This appears to be an issue when using a Nutanix Storage Cluster. Please reference these 2 articles:
