If the remote system crashes then any memory regions, QPs, etc. are still valid with the remote HCA, and RDMA read/write operations will continue to succeed. (Unless the system reboots and reinitializes the adapter or something like that). There isn't a way to detect a remote crash unless that remote crash disconnects your QP or otherwise affects the HCA on the crashed system. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
