NAME

       lsimega - SCSI HBA driver for LSI MegaRAID 320-2x SCSI  RAID Controller

       The lsimega SCSI RAID  host bus adapter driver is a SCSA-compliant nexus driver that supports LSI MegaRAID 320-2x SCSI RAID devices.

       The  lsimega  driver supports  standard  functions provided by the SCSA interface, including RAID disk I/O  and  passthrough I/O to support
       SCSI tape and CDROM.

DRIVER CONFIGURATION

       The lsimega.conf file contains no user configurable parameters. Please configure your hardware through BIOS.

       The LSI MegaRAID 320-2x device can support up to 40 logic drivers. Note that BIOS numbers the logic drives as  1  through  40,  however  in
       Solaris these drives are numbered from 0 to 39.
