摘要
A method and system for maintaining a unique reserve command relationship between an initiator and a target device in a Fibre Channel network across network address changes after a break in communication. The present invention maintains triplet tables containing data triplets, comprised of the network address, the port name, and the node name, for each initiator and each target device. Following a break in network communication that results in the network address of an initiator and/or a target device changing, the method of the present invention updates the recorded network addresses for the initiators and the target devices, maintains any previously-existing unique reserve command relationships and continues with I/O transmission. Although the network address of an initiator may change, the node name and port name of the initiator will remain the same. By comparing the initiator port name and node name contained in a reserve table maintained in the target device to the node name and port name corresponding to the now updated network address for an initiator with which it was in a unique reserve command relationship prior to the break in communication, a target device can then simply update the network address for the initiator and no disruption in I/O traffic will result.
