    Nested All Flash Input

    barnette08 Hot Shot

      Hey all,

       

      I know this is a worn out topic with plenty of hits online, but I can't seem to find anything specific to all flash.  Below is my output of vdq and you can see that I've set all the disks to isSSD=1 and IsCapacityFlash=1.  What am I missing here?  I'm not able to see a cache tier when attempting to do the configuration.  Any ideas or links would be greatly appreciated.

          IsCapacityFlash=1 marks it as capacity tier, you need will need to change that to 0 on one of the devices

            I had tried that on the first host, but not the other 3 to see if it helped but it didn't originally.  So I went back this morning and did it on the last drive on each host (doubt that mattered), and we are off and running.  I am doing this on a VCF bringup using Cloud Builder so it could easily just be the validation process that Cloud Builder uses and wants all 4 hosts to have cache tier before passing validation.  Eitherway, thanks for the sanity check!
