We have very high DA utilization on a number of directors but not all and so it makes us think it is not likely TDEV's but STD dev's which are carved out of certain Raid Groups. I see nowhere in SPA that allows me to sort/search by Devices if I don't know the specific SG. I do know a DA but no mention of STD device beneath it. How does one approach this?

1 or more STD devs (possibly R6 or R1) of unknown dev ID, believed to be used by 1 or more SG. The only symptom is 90+% utilization on some DA's. Appreciated!
