Two Windows servers in SAN

I have two Windows 2016 servers with QLogic HBA. Servers connect to a Brocade SAN switch. Servers can ping fabric via QLogic FC ping utility. But one server don't see the other. In "Target list" in "QConvergeConsole" WWN not listed.
New zone on Brocade with this WWN's created and applied. What do I need to do to establish connectivity?

This is exactly how SANs are supposed to work: you can only make connections from servers to targets (i.e. storage devices), not to other servers.

It would be completely useless to test connectivity between servers, because you'll never actually make a direct connection between two of them.

This is also confirmed by the product documentation:

FC Ping and FC Trace Route are easily accessed within the QConvergeConsole® (QCC) GUI management application, and provide a simple way to verify connectivity between a SAN-connected server and storage device.

Please note the "between a SAN-connected server and storage device" part.

What do I need to do to establish connectivity?

Nothing, if you can reach the targets from the servers then everything is fine; there is no need at all for the servers to talk to each other through the SAN: that is what actual network connections are for.
