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!
