These chips support SAS/SATA interfaces, 22 including tagged and untagged queuing, multiple MSI-X interrupts, LSI 23 fastpath and SATA 3G/6G/12G. 24 .SS "Configuration" 25 .sp 26 .LP 27 The \fBmpt_sas3\fR driver is configured by defining properties in 28 \fBmpt_sas3.conf\fR. These properties override the global SCSI settings. The 29 \fBmpt_sas3\fR driver supports one modifiable property: 30 .sp 31 .ne 2 32 .na 33 \fB\fBmpxio-disable\fR\fR 34 .ad 35 .sp .6 36 .RS 4n 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. 40 .sp 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. 43 .sp 44 The following example shows how to disable multipathing on port 0 whose parent 45 is \fB/pci@0,0/pci8086,2940@1c/pci1000,90@0\fR: 46 .sp 47 .in +2 48 .nf 49 name="mpt_sas3" parent="/pci@0,0/pci8086,2940@1c/pci1000,90@0" 50 mpxio-disable="yes"; 51 .fi 52 .in -2 53 54 The \fBmpt_sas3\fR host bus adapter driver is also capable of driving older 55 SAS2 controllers cards such as 2008 - 2308. Replacing the older mpt_sas driver 56 with mpt_sas3 will automatically enhance the performance where the card 57 is capable. 58 59 .RE 60 61 .SH EXAMPLES 62 .LP 63 \fBExample 1 \fRUsing the \fBmpt_sas3\fR Configuration File to Disable MPXIO 64 .sp 65 .LP 66 Create a file called \fB/kernel/drv/mpt_sas3.conf\fR and add the following line: 67 68 .sp 69 .in +2 70 .nf 71 name="mpt_sas3" parent="/pci@0,0/pci8086,2940@1c/pci1000,90@0" 72 mpxio-disable="yes"; 73 .fi 74 .in -2 75 76 .SH FILES 77 .sp 78 .ne 2 79 .na 80 \fB\fB/kernel/drv/mpt_sas3\fR\fR 81 .ad 82 .sp .6 83 .RS 4n 84 32-bit ELF kernel module 85 .RE 86 87 .sp 88 .ne 2 89 .na 90 \fB\fB/kernel/drv/sparcv9/mpt_sas3\fR\fR 91 .ad 92 .sp .6 93 .RS 4n 94 64-bit SPARC ELF kernel module 95 .RE 96 97 .sp 98 .ne 2 99 .na 100 \fB\fB/kernel/drv/amd64/mpt_sas3\fR\fR 101 .ad 102 .sp .6 103 .RS 4n 104 64-bit x86 ELF kernel module 105 .RE 106 107 .sp 108 .ne 2 109 .na 110 \fB\fB/kernel/drv/mpt_sas3.conf\fR\fR 111 .ad 112 .sp .6 113 .RS 4n 114 Optional configuration file 115 .RE 116 117 .SH ATTRIBUTES 118 .sp 119 .LP 120 See \fBattributes\fR(5) for a description of the following attributes: 121 .sp 122 123 .sp 124 .TS 125 box; 126 l | l 127 l | l . 128 ATTRIBUTE TYPE ATTRIBUTE VALUE 129 _ 130 Architecture SPARC, x86 131 .TE 132 133 .SH SEE ALSO 134 .sp 135 .LP 136 \fBprtconf\fR(1M), \fBdriver.conf\fR(4), \fBpci\fR(4), \fBattributes\fR(5), 137 \fBscsi_abort\fR(9F), \fBscsi_device\fR(9S), \fBscsi_extended_sense\fR(9S), 138 \fBscsi_inquiry\fR(9S), \fBscsi_hba_attach_setup\fR(9F), \fBupdate_drv\fR(1M), 139 \fBscsi_ifgetcap\fR(9F), \fBscsi_ifsetcap\fR(9F), \fBscsi_pkt\fR(9S), 140 \fBscsi_reset\fR(9F), \fBscsi_sync_pkt\fR(9F), \fBscsi_transport\fR(9F),
