*************************** General Description **************************

This software is a LSI Logic Fusion-MPT Solaris Sparc driver and utility package that supports LSI40909G-S host adapter product. 

The LSI Logic driver, itmpt, allows the Solaris SPARC operating system to interface with the FC devices connected to the LSI40909G-S. The LSI Logic driver is optimized for low CPU overhead and high I/O throughput, making use of the LSI Logic Fusion-MPT architecture. LSI Logic FC40909G-S adapters have built-in Fcode, designed to operate in the Sun OpenBoot environment, allowing FC devices to be available to the OpenBoot (ok) prompt. This driver takes advantage of new hardware features in the LSI40909G-S to minimize CPU utilization, including interrupt coalescing, which can result in less than one interrupt per I/O. 

The LSI Logic driver also provides a means to preserve a consistent mapping between Solaris target IDs and FC target devices, by providing a configuration file with entries that map each Solaris target ID to an FC target World Wide Name. Note that this is done for all FC target devices, and is in addition to the Root Boot persistent target ID selection, which is configurable through the Fcode BIOS. Persistent bindings are required for most RAID controllers such as the LSI Logic Metastor.  Two utilities are provided to configure the persitent bindings in the driver. 
 
******************************** Overview ********************************

* Driver Features *

  - Uses state of the art Fusion-MPT interface, providing support for FC,
    SCSI, and RAID devices with a single binary image.
  - Provides highly efficient, low CPU usage architecture.
  - 66 MHz/64-bit PCI interface support provides maximum I/O bandwidth.
  - Supports multiple host adapters.
  - Supports multiple Logical Unit Numbers (LUNs) 
  - Supports scatter/gather.
  - Supports disk array configurations with no LUN 0 
  - Supports disk array configurations with non-contiguous LUNs 
  - Supports multiprocessor environments. 

* Utility Features *

- lsiadm utility is used to maintain persistent bindings between targets and
    WWNs, by  automatically adding bindings to, or deleting bindings from, the
    /kernel/drv/itmpt.conf file, used by the itmpt driver.
  - lsiprobe utility automatically adds extended LUN support to, or deletes
    extended LUN support from, the /kernel/drv/ssd.conf file, used by the itmpt
    driver.

* System Requirements *

This software requires:

- A Sun Solaris system, with Solaris 2.6 release or later
- Sun OpenBoot PROM Version 3.0 or later 

**************************** Before You Begin ********************************

Before using this software, the LSI Logic FC40909G-S controller should be configured into your system, taking into account the configuration of other host adapters and system resources.

LSI Logic recommends that all data be backed up before making any changes 
or installing any software, including LSI Logic FC controllers and software.
Failure to adhere to this accepted computer practice may lead to loss of data.

The driver and utilities can be installed directly using pkgadd. Alternately, if the LSI 40909G-S is used to support your system disk, a Sparc or Intel Solaris boot server can be used as a Network Boot Server.

Please refer to the 40909G-S User Guide for detailed installation instructions.
