NAME
     mr_sas - LSI MegaRAID SAS2.0 Controller HBA driver

DESCRIPTION
     The mr_sas  MegaRAID  SAS2.0  controller  host  bus  adapter
     driver  is  a  SCSA-compliant nexus driver that supports the
     LSI MegaRAID SAS 92xx series  of  controllers  and  the  Sun
     StorageTek 6Gb/s SAS RAID HBA series of controllers.


     Some of the RAID Features include the following:

         o    RAID levels 0, 1, 5, and 6

         o    RAID spans 10, 50, and 60

         o    Online Capacity Expansion (OCE)

         o    Online RAID Level Migration (RLM)

         o    Auto resume  after  loss  of  system  power  during
              arrays array rebuild or reconstruction (RLM)

         o    Configurable stripe size up to 1MB

         o    Check Consistency for background data integrity

         o    Patrol read for media scanning and repairing

         o    64 logical drive support

         o    Up to 64TB LUN support

         o    Automatic rebuild

         o    Global and dedicated Hot Spare support


     The mr_sas driver also supports the  following  Dell  cards:
     PERC  H700 Integrated, PERC H700 Adapter, PERC H700 Modular,
     and the PERC H800 Adapter.

  Configuration
     The uneditable mr_sas.conf file contains  one  user  private
     configurable  parameter, for MSI or MSI-X support. Configure
     your hardware through the related BIOS utility or the  Mega-
     Cli Configuration Utility. If you want to install to a drive
     attached to a mr_sas HBA, create  the  virtual  drive  first
     from  the  BIOS  (X86)  before  running Solaris install. The
     MegaCli utility can be downloaded from the LSI website.

     The LSI MegaRAID SAS device can support  up  to  64  virtual
     SAS2.0, SAS1.0, SATA3.0, or SATA 6.0 disks. The BIOS numbers
     the virtual disks as 1 through 64, however in Solaris  these
     drives are numbered from 0 to 63. Also keep in mind that SAS
     and SATA drives can not be configured into the same  virtual
     disk.
