NAME

mpt_sas - SAS-2 host bus adapter driver  

SYNOPSIS

[email protected]

 

DESCRIPTION

The mpt_sas host bus adapter driver is a nexus driver that supports the LSI SAS200x/2108 series of chips. These chips support SAS/SATA interfaces, including tagged and untagged queuing, SATA 3G/SAS 3G/SAS 6G.  

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 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 [email protected],0/pci8086,[email protected]/pci1000,[email protected]:

name="mpt_sas"    parent="[email protected],0/pci8086,[email protected]/pci1000,[email protected]" 
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="[email protected],0/pci8086,[email protected]/pci1000,[email protected]"
mpxio-disable="yes";
