mpt_sas - SAS-2/3 host bus adapter driver
scsi@unit-address
The
mpt_sas host bus adapter driver is a nexus driver that supports
Broadcom (formerly LSI and Avago) SAS chipsets including the SAS200x/2x08/2x16
and SAS300x/3x08/3x16/3x24 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";
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";
