3.2.1 Introducing the Solaris SPARC Driver
The LSI driver, itmpt , allows the Solaris SPARC operating system to
interface with the devices connected to the LSI Ultra320 SCSI, SAS, and
Fibre Channel host adapters. The LSI driver is optimized for low CPU
overhead and high I/O throughput, making use of the LSI Fusion-MPT
architecture. LSI adapters have built-in FCode, designed to operate in
the Sun OpenBoot environment, allowing devices to be available to the
OpenBoot (ok) prompt. The driver takes advantage of new hardware
features in the LSI Ultra320 SCSI, SAS, and Fibre Channel chips to
minimize CPU utilization, including interrupt coalescing, which can result
in less than one interrupt per I/O.
The lsiutil utility, which is included with the itmpt driver, provides a
wealth of functionality for displaying and modifying settings for LSI MPT
adapters. This includes updating the FCode, firmware, and BIOS on an
MPT adapter as well as managing target persistence. You can execute
lsiutil with no arguments to start an interactive session. You can also
use the command lsiutil -h to view information about the lsiutil
command line options. This utility is installed to /usr/bin/lsiutil .
For Fibre Channel adapters, the lsiprobe utility configures extended
LUN support by automatically adding or deleting extended LUN support
from the
/kernel/drv/ssd.conf file, used by the itmpt driver.
