NAME

     mfi -- LSI Logic & Dell MegaRAID SAS RAID controller

SYNOPSIS

     mfi* at pci? dev ? function ?

DESCRIPTION

     The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including:

	   -   Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
	   -   Intel RAID Controller SRCSAS18E, SRCSAS144E
	   -   LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID
	       SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i
	   -   IBM ServeRAID M1015, ServeRAID M5014

     These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives.

     Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.

     mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands.

EVENTS

     The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online.  The state-changed event will be sent
     to the /etc/powerd/scripts/sensor_drive script when such condition happens.

HISTORY

     The mfi driver first appeared in NetBSD 4.0.

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.
