I am looking to add a HBA disk controller to an existing ESXI 6.5 server to pass-through to a VM. When I use the old vSphere client I can see the adapter in the Storage Adapters section, but I cannot do anything with it. Clicking on the reference (LSI2008 -> vmhba1 if that is at all relevant) jst returns the message
An internal error occurred in the vSphere Client.
Details: Object reference not set to an instance of an object.
I have searched all over the place for any guidance on how to do this but have not been able to find anything about how to get VMware to recognise the HBA so I can see the disks and pass them through. If anyone could either point me in the direction of such a resource I would be grateful - or is it impossible to add an additional HBA to an existing system?
