Virtual HBAs and Hyper-v

Hi,

I have a six node virtual sql cluster, running off of an 8 node physical cluster for using hyper-v 2022. The storage is presented from a DELL COMPELLENT 3020 The zoning is via brocade. My question is why would some hosts be able to live migrate all of the vhbas and others not be able to? If the zoning was incorrect, there would no live migration at all possible. I also do the zoning. I am not the server person but need to get a better understanding of why this is.  Please see attached diagram. Any input would be greatly appreciated
