Hi,
I, too, am experiencing the same issue. The firewalls are all open between the vlans containing the source, converter, and ESX hosts. I still get an error stating that the communications between the source and target disk is not available. I have port 9089 opened to the source for the agent install, port 902 for the connection between the source and target, and everything in between open.
I see the same error being thrown each time and when I searched on it, I found this article.
Any help would be appreciated.
Thanks,
Stan
