Does Solaris multipathing work with iSCSI?
Yes, Solaris multipathing works with iSCSI. MPxIO is a Solaris component that supports multiple physical paths to storage. Because MPxIO operates above the transport layer, it can support FC, InfiniBand (IB) and iSCSI. FC and iSCSI drivers register logical units with MPxIO. MPxIO matches paths to the same logical unit at the SCSI protocol layer by querying the unique SCSI per LUN identifier from each device. MPxIO then collapses duplicate paths to one device so that the target driver and layers above know only of the one device.
