NAME
     smp - Serial Attached Management Protocol Target Driver

SYNOPSIS

     smp@w<sas_addr>:smp

DESCRIPTION

     The smp(7D)  target driver binds to SMP  target devices such
     as  SAS switches  or  SAS expanders.  Unlike  a SCSI  target
     device, SMP target devices do  not respond to a SCSI inquiry
     command, so the SCSA  framework can not enumerate SMP target
     devices  by  using  the  standard  SCSI  probe  methods.  To
     enumerate SMP target devices the SAS HBA driver must support
     target device self-discover and self-enumeration.

     The smp(7D)  driver exports  the usmp(7I) interface  to user
     processes.  With  the interface,  SMP  request and  response
     frames are  transported between the  management applications
     and SMP target devices.

SECURITY

    The  access is  restricted and  device nodes  created  by the
    smp(7D) driver  are readable  and writable only  by processes
    with the PRIV_SYS_DEVICES privilege exclusively.

DEVICE SPECIAL FILES

    The SMP target devices  have device minor nodes created under
    the corresponding HBA path  in /devices. Convenient links in
    the  /dev/smp  directory are  created  for  the device  minor
    nodes.

FILES

    /kernel/drv/smp.conf  driver configuration file
    /dev/smp/expdX        smp device file

    where:

    X  indicates a SMP target device instance.
