mpath provides access, I/O multiplexing,
and failover support to SCSI logical units that can have multiple physical
connections to the system. It uses connections presented by path drivers,
for example sym(4), as backends to a single device attached to its own
ioctl(2), emc(4), hds(4), intro(4), rdac(4), scsi(4), sym(4)
