I didn't realize the Flash client was still enabled, but once I tried using that I was able to create the datastore without issue.

I will also note that the HTML 5 client doesn't seems to include Host Clusters in the Hardware Resources page for some reason.

"how did you upgrade the VSA to 6.0?" 

I followed the instructions in the user guide to upgrade.

"Also have you tried reboot thing the client afterwards?"

I assume by "reboot thing" you mean the appliance, yes, I did try rebooting the appliance. 

"Or even try installing?"

I don't understand what you are trying to say here.

"This is the manual and I don't particular see the issue you are experiencing."

I included a screen shot of the issue. I don't know what you think this last statement accomplishes. 

Hello, how did you upgrade the VSA to 6.0? Also have you tried reboot thing the client afterwards?
Or even try installing?

This is the manual and I don't particular see the issue you are experiencing.

Hi @REKnight,

I assumed VSA, you're referring to EQL Virtual Storage Manager?

What is your ESXi version?

Are you creating a VMFS datastore? Is it the same if you select VVol? 

What is your EQL product model?

Yes, I am referring to the EqualLogic Virtual Storage Manager.

ESXi 6.7U3

Yes, I am creating a VMFS datastore. I have no need to create a VVol, so I haven't tried.

PS-M4110

Hello, 

 I am glad you were able to discover that the FLASH GUI is still enabled.   They are two separate plugins.  

  Would you be willing to open a support case?    They will need logs from the EQL array, VSM and vCenter and the ESXI nodes.   What firmware is on the PSM4110?   Hopefully 10.0.3? 

 Regards, 

Don
