  21 The \fBmpt_sas\fR host bus adapter driver is a nexus driver that supports the
  22 LSI SAS200x/2x08 and SAS300x/3x08 series of chips. These chips support SAS/SATA

  23 interfaces, including tagged and untagged queuing, SATA 3G/SAS 3G/SAS 6G/SAS
  24 12G.

  28 The \fBmpt_sas\fR driver is configured by defining properties in
  29 \fBmpt_sas.conf\fR. These properties override the global SCSI settings. The

  40 multipathing, while \fBmpxio-disable="yes"\fR disables I/O multipathing.

  42 Solaris I/O multipathing can be enabled or disabled on a per port basis. Per
