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 back-
     ground 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  sup-
     port.

CONFIGURATION
     The mega_sas.conf file contains no user configurable parame-
     ters.  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 virtual disk.

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