MSA2060 Specifically how is a SSD Read Cache created for a volume

Documentation states that without the LTU license, SSD's can be used as Read Cache for a Volume.  Prior to obtaining and importing the license, I was unable to do this.  As soon as I plugged in SSD's, their LED's were yellow and SMU stated they couldn't be used as there was no license.

Now that I have a license, I can create a volume from SSD's, but how exactly do I assign an SSD to a spinning disk volume to be used as read cache instead?  Has anyone actually done this. How did you do it?

Turns out that read cache provides no benefit for my workload (linux page cache is sufficient).  Write cache is what would be helpful.  No longer trying to configure SSD read cache...but not encouraged by need to use the cli to do this...in properly designed user interface it would be possible to perform all functions from the SMU.  Did not attempt the instructions that were provided as I don't need read cache.  Consider this case resolved.
