how RPA CLUSTER select non-preferred RPA
If I have 4 RPAs in a cluster, when preferred RPA of a CG down, what policy will be used to select a non preferred RPA to switchover this CG? Is it according to load balance policy? Or just random select?

If the primary RPA fails, one of the secondary RPAs is chosen to replace it as primary and another secondary RPA is randomly selected.

Currently this is random.

Thanks Rich.
If I have 8 rpas in a cluster, and I create a distributed CG with 4 RPAs(RPA1,RPA2,RPA3,RPA4), and use RPA4 as primary RPA, if RPA4 down, will CLUSTER choose new non-preferred RPA from RPA5\RPA6\RPA7\RPA8 to keep the number of rpa of distribute CG, or it just also random select, even the number of rpa serve this DCG degraded to 3?
