A failure at a first port of the controller node is detected, where the first port is initially assigned a first port identifier and is associated with a logical path through a communications fabric between the first port and a port at a host device. In response to detecting the failure, the first port identifier is assigned to a second port to cause the logical path to be associated with the second port. In response to detecting resolution of the failure, a probe identifier is assigned to the first port. Using the probe identifier, a health of network infrastructure between the first port and the host device is checked. In response to the checking, the first port identifier is assigned to the first port to cause failback of the logical path to the first port.
