NAME # mpath - SCSI multipath
SYNOPSIS # emc* at scsibus? hds* at scsibus? rdac* at scsibus? sym* at scsibus?
mpath0 at root
DESCRIPTION # 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 scsibus(4).

SYNOPSIS # rdac* at scsibus?
DESCRIPTION # The rdac driver attaches to Engenio/LSI RDAC SCSI logical units. Each path to an active service processor attached to by rdac is presented to mpath(4) which uses it as a backend to the logical unit attached to its own scsibus(4).
