NAME
     mpt_sas - SAS-2 host bus adapter driver

SYNOPSIS
       scsi@unit-address


DESCRIPTION
     The mpt_sas host bus adapter driver is a nexus  driver  that
     supports  the  LSI SAS200x/2108 series of chips. These chips
     support SAS/SATA interfaces, including tagged  and  untagged
     queuing,  SATA 3G/SAS 3G/SAS 6G. The mpt_sas driver supports
     the following Dell cards: PERC H200  Integrated,  PERC  H200
     Adapter, PERC H200 Modular, and 6Gbps SAS HBA.

  Configuration
     The mpt_sas driver is configured by defining  properties  in
     mpt_sas.conf. These properties override the global SCSI set-
     tings. The mpt_sas driver supports one modifiable property:

     mpxio-disable

         Solaris I/O multipathing is enabled or disabled  on  SAS
         devices  with  the  mpxio-disable  property.  Specifying
         mpxio-disable="no"  activates  I/O  multipathing,  while
         mpxio-disable="yes" disables I/O multipathing.

         Solaris I/O multipathing can be enabled or disabled on a
         per  port  basis.  Per port settings override the global
         setting for the specified ports.

         The following example shows how to disable  multipathing
         on        port       0       whose       parent       is
         /pci@0,0/pci8086,2940@1c/pci1000,72@0:

           name="mpt_sas"    parent="/pci@0,0/pci8086,2940@1c/pci1000,72@0"
           mpxio-disable="yes";



EXAMPLES
     Example 1 Using the mpt_sas Configuration  File  to  Disable
     MPXIO


     Create a file called /kernel/drv/mpt_sas.conf  and  add  the
     following line:


       name="mpt_sas"    parent="/pci@0,0/pci8086,2940@1c/pci1000,72@0"
       mpxio-disable="yes";
