Unable to add Storage System from the VSC plugin

After deploying the VSC appliance it was not possible to add a Storage System. The IP or FQDN is simply not recognized, hence the red warning with exclamation at “Name or IP address”

I could not explain this as for the VSC application was deployed correctly within vCenter with all the services running in the appliance

Further more:

The network settings are setup correctly (successful configuration walkthrough during VSC appliance deployment)
All the necessary services are started (pre-requisite for a successful deployment)
IP/FQDN added to DNS in the corresponding domain
Communication is allowed for the necessary ports in the firewall (80, 443, 8143, 8043)
IP of the VSC is reachable from the VCSA appliance and vice versa (ping)
Compatibility between the different components checked and everything is supported

Next step was to analyze the log files from the appliance and the control panel:

Almost right away the following message appeared (1st line):

Unable to connect to vCenter Server at "YourvCenterServer".
	at com.netapp.vasa.vvol.support.ErrorMapper.newStorageFaultException(ErrorMapper.java:442)
	at com.netapp.vasa.vvol.support.ErrorMapper.newStorageFaultException(ErrorMapper.java:416)

So I decided to unregister the VSC and VASA Provider extentsions from vCenter and to remove the UI extentions from vSphere. Maybe it has something to do with the plug-ins in vCenter

Unregister VSC and VASA Provider extionsions from vCenter through VMWare’s MOB

Go to https://”Your-vCenter”/mob and use admin credentials to log in

Go to > Content

Select “ExtensionManager”

Select “UnregisterExtension”

A new windows appears

Use the following string to remove the VASA Provider: com.netapp.vasa.vvol.webclient and select > Invoke Method

Do the same for the following plug-ins

com.netapp.nvpf
com.netapp.vsch5
com.netapp.nvpf.webclient

Close the UnregisterExtension window and refresh the “ManagedObjectReference:ExtensionManager” window. Check whether the plug-ins are removed from the extension list

Now perform the following steps in VCSA

Now I did a “Rediscover All” and the Storage System was there!

Now go to Actions > Modify to validate the credentials. Make sure that you use a test account for this purpose
