Abstract
Embodiments include performing a host-initiated link reset in a storage area network (SAN). Aspects include identifying, by a host in communication with the SAN, each link in the SAN, wherein each link is defined by a pair of ports. Aspects also include obtaining, by the host, a buffer credit balance for each port in the SAN and obtaining, by the host, a buffer credit for each port in the SAN and causing a reset of a link associated with the port by transmitting a link reset record from the host to a control device of the link based on a determination that the buffer credit of a port in the SAN is below a threshold value.
