NAME

       mega_sas - SCSI HBA driver for LSI MegaRAID SAS controller

DESCRIPTION

       The mega_sas MegaRAID controller host bus adapter driver  is a  SCSA-compliant  nexus  driver that supports the Dell PERC 5/E, 5/i, 6/E and
       6/i RAID controllers, the IBM ServeRAID-MR10k SAS/SATA  controller and  the  LSI  MegaRAID  SAS/SATA  8308ELP,  8344ELP,  84016E,  8408ELP,
       8480ELP, 8704ELP, 8704EM2, 8708ELP, 8708EM2, 8880EM2 and 8888ELP series of controllers.

       Supported  RAID	features  include RAID levels 0, 1, 5, and 6, RAID spans 10, 50 and 60, online capacity expansion (OCE), online RAID level
       migration (RLM), auto resume after loss of  system power during arrays, array rebuild or reconstruction (RLM) and configurable stripe  size
       up  to  1MB. Additional supported RAID features include check consistency for background data integrity, patrol read for media scanning and
       repairing, 64 logical drive support, up to 64TB LUN support, automatic rebuild and global and dedicated hot spare support.

CONFIGURATION

       The mega_sas.conf file contains no user configurable parameters. Please configure your hardware through the related  BIOS  utility  or  the
       MegaCli	configuration  utility.  If  you  want to install to a drive attached to a mega_sas HBA, you should create the virtual drive first
       from the BIOS before running the Solaris install. You can obtain the MegaCli utility from the LSI website.

       The mega_sas device can support up to  64 virtual disks. Note that BIOS numbers the virtual disks as 1 through 64, however in  the  Solaris
       operating  environment virtual disks are numbered from 0 to 63.	Also note that SAS and SATA drives cannot be configured into the same vir-
       tual disk.

KNOWN PROBLEMS AND LIMITATIONS

       The mega_sas driver does not support the LSI MegaRAID SAS 8204ELP, 8204XLP, 8208ELP, and 8208XLP controllers.

NAME

     mpt -- LSI Fusion-MPT SCSI/Fibre Channel driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device mpt

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   mpt_load="YES"

DESCRIPTION

     The mpt driver provides support for the LSI Logic Fusion-MPT family of SCSI, Fibre Channel and SAS controllers.

HARDWARE

     The following controllers are supported by the mpt driver:

     o	 LSI Logic 53c1030, LSI Logic LSI2x320-X (Single and Dual Ultra320 SCSI)
     o	 LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)
     o	 LSI Logic FC909 (1Gb/s Fibre Channel)
     o	 LSI Logic FC909A (Dual 1Gb/s Fibre Channel)
     o	 LSI Logic FC919, LSI Logic 7102XP-LC (Single 2Gb/s Fibre Channel)
     o	 LSI Logic FC929, LSI Logic FC929X, LSI Logic 7202XP-LC (Dual 2Gb/s Fibre Channel)
     o	 LSI Logic FC949X (Dual 4Gb/s Fibre Channel)
     o	 LSI Logic FC949E, LSI Logic FC949ES (Dual 4Gb/s Fibre Channel PCI-Express)

     The Ultra 320 SCSI controller chips supported by the mpt driver can be found onboard on many systems including:

     o	 Dell PowerEdge 1750 thru 2850
     o	 IBM eServer xSeries 335

     These systems also contain Integrated RAID Mirroring and Integrated RAID Mirroring Enhanced which this driver also supports.

     The SAS controller chips are also present on many new AMD/Opteron based systems, like the Sun 4100.  Note that this controller can drive both
     SAS and SATA drives or a mix of them at the same time. The Integrated RAID Mirroring available for these controllers is poorly supported at
     best.

     The Fibre Channel controller chipset are supported by a broad variety of speeds and systems.  The Apple Fibre Channel HBA is in fact the
     FC949ES card.

     This driver also supports target mode for Fibre Channel cards.  This support may be enabled by setting the desired role of the core via the
     LSI Logic firmware utility that establishes what roles the card can take on - no separate compilation is required.
