mpt_sas(7D) Devices mpt_sas(7D)NAMEmpt_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/2108/2308, and SSS6200 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 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 multi‐
pathing.
Solaris I/O multipathing can be enabled or disabled on a per port
basis. Per port settings override the global setting for the speci‐
fied 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";
