The term "FBA" is ambiguous in this context. Are you using z/VM FBA EDEVICEs or are you giving Linux guests direct access to SCSI LUNs?
I know this sounds trite, but you do it in DR the same way you do it at home. To connect to a SCSI device, there are 4 elements: 1. The initiator (client) WWPN assigned to a specific FCP subchannel on the Z/LinuxONE box 2. The target (server) WWPNs assigned to the storage controller 3. The LUN within the storage controller 4. The permissions within the SAN fabric that allows the initiator WWPNs to talk to the target WWPNs. So at home your z/VM and/or Linux configurations include the target WWPNs and LUNs. The storage controller configuration gives one or more initiator WWPNs access to one or more LUNs. And of course the SAN fabric is configured to allow the WWPN pairs to talk to each other. All of that must be done in DR where the equipment is different and so are the WWPNs and, possibly, LUN numbers. On top of that you have the mechanism that copies the application data from home to DR and back. How you handle the differences between home and DR depend on whether you maintain a separate system for each site with its own configuration or whether you use a single system (or set of systems) that adapt themselves to their location when they IPL based on environmental information that can tell it whether it is in DR or at home.
