Hi Mike, Our intention is to train the multipathd for pushing the multipath info into the fabric using LIBHBA api's. Can we call libhba apis in multipathd to push the info into fabric?

Sounds like you'd probably want to expose APIs that enable you to access the state you require from multipathd rather than train multipathd to inject anything into the fabric.
