    摘要: A method of multi-path accessing a remote logic device under a Linux system is used to realize a multi-path access between an initiator and a target in a storage area network (SAN). Firstly, a communication is established between the initiator and the target. Next, the initiator requests to establish at least one link session with the target. Then, the initiator obtains an iSCSI-connected host assigned by the target, and also obtains a message about connected devices corresponding to the iSCSI-connected host through transmitting a report logic unit number (LUN) command. Then, the initiator configures a device mapper, and the device mapper generates information about redundant devices according to the connected devices and the corresponding LUNs, and the redundant connected devices are mapped into a unique mapping device.
