scsi@unit-address
The mpt_sas host bus adapter driver is a nexus driver that supports the LSI SAS200x/2x08 and SAS300x/3x08 series of chips. These chips support SAS/SATA interfaces, including tagged and untagged queuing, SATA 3G/SAS 3G/SAS 6G/SAS 12G.
The mpt_sas driver is configured by defining properties in mpt_sas.conf. These properties override the global SCSI settings. 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";
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";
