10 mpt_sas \- SAS-2/3 host bus adapter driver
20 The \fBmpt_sas\fR host bus adapter driver is a nexus driver that supports
21 Broadcom (formerly LSI and Avago) SAS chipsets including the SAS200x/2x08/2x16
22 and SAS300x/3x08/3x16/3x24 series of chips. These chips support SAS/SATA
23 interfaces, including tagged and untagged queuing, SATA 3G/SAS 3G/SAS 6G/SAS
27 The \fBmpt_sas\fR driver is configured by defining properties in
28 \fBmpt_sas.conf\fR. These properties override the global SCSI settings. The
29 \fBmpt_sas\fR driver supports one modifiable property:
33 \fB\fBmpxio-disable\fR\fR
37 Solaris I/O multipathing is enabled or disabled on SAS devices with the
38 \fBmpxio-disable\fR property. Specifying \fBmpxio-disable="no"\fR activates I/O
39 multipathing, while \fBmpxio-disable="yes"\fR disables I/O multipathing.
41 Solaris I/O multipathing can be enabled or disabled on a per port basis. Per
42 port settings override the global setting for the specified ports.
44 The following example shows how to disable multipathing on port 0 whose parent
45 is \fB/pci@0,0/pci8086,2940@1c/pci1000,72@0\fR:
49 name="mpt_sas" parent="/pci@0,0/pci8086,2940@1c/pci1000,72@0"
