SNAPVX status

Hello,

I have a query regarding SNAPVX in VMAX3 family and above. Writing method provided is either COW or ROW

1) How can I check whether my SNAP session is COW or ROW ?

2) Is there a way to check details of SNAP pool in VMAX 3 ?

Either using symcli/Unisphere for VMAX anyone will be helpful

Thanks to the amazing brain in advance!!
