Does RDQM support multiple FIPs for a QMgr?
Say I want two LSTRs on two different NICs because traffic is being routed over two vendors (for diversity) to a partner. On the CONNAME, I list the two FIPs. They will be tried in the order listed. Obviously, I need both FIPs to move when the QMgr moves between the nodes.

The RDQM internals have little to do in the way you access the qmgr from outside the RDQM cluster.
Go with the 2 LSTRs however you may need 3 ips(port) per listener local address). I would expect that the 2 ips are not in the same subnet (different Nic Cards).
Hope it helps

Hmmm, the way I read and have experienced FIP under the control of the RDQM process, is that the RDQM process is binding the FIP and hostname that goes with it to the node where the RDQM QMgr is "primary".
Of course, Azure does not allow this and you have to use a FIP provided by Azure or F5 (further away from the QMgr). |

Exactly, which is why the Azure RDQM is accessed via a Service definition which in fine resolves to the running qmgr. That service definition may contain the channel name. If the definition is too long for zOS, you may have to create a DNS Alias that points to the service routing.
Hope it helps
