RE: how to preserve QP over HA events for librdmacm applications

I too would be interested in bringing a QP from error back to a usable state. I
have been debating whether to reconnect using the current RDMA calls versus
trying to transition the existing RC QP.

I assumed to transition the existing QP that I would need to open a socket to
coordinate the two sides. Is that correct?

If I were instead to use rdma_connect(), does it require a new CM id or just a
new QP within the same id?

What do you gain by transitioning an RC QP from error to RTS, versus just establishing a new connection?
