Open these ports between the management ports of arrays, between the two vcenter/srm servers and between these last and the arrays management!
2463, no idea of its reason
1701 is the “internal” port of the service…why there’s a call outside? But there are calls outside
3260 is the iSCSI port…for which reason the SRA should send iSCSI command out of the vcenter toward the management of the array? But you need it!
Documentation from this point of view is very poor...
