.SH NAME
mega_sas \- SCSI HBA driver for LSI MegaRAID SAS controller
.SH DESCRIPTION
.sp
.LP
The \fBmega_sas\fR 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.
.sp
.LP
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.
.SH CONFIGURATION
.sp
.LP
The \fBmega_sas.conf\fR 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.
.sp
.LP
The \fBmega_sas\fR 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.
.SH KNOWN PROBLEMS AND LIMITATIONS
.sp
.LP
The \fBmega_sas\fR driver does not support the LSI MegaRAID SAS 8204ELP,
8204XLP, 8208ELP, and 8208XLP controllers.
