8 mega_sas \- SCSI HBA driver for LSI MegaRAID SAS controller
12 The \fBmega_sas\fR MegaRAID controller host bus adapter driver is a
13 SCSA-compliant nexus driver that supports the Dell PERC 5/E, 5/i, 6/E and 6/i
14 RAID controllers, the IBM ServeRAID-MR10k SAS/SATA controller and the LSI
15 MegaRAID SAS/SATA 8308ELP, 8344ELP, 84016E, 8408ELP, 8480ELP, 8704ELP, 8704EM2,
16 8708ELP, 8708EM2, 8880EM2 and 8888ELP series of controllers.
19 Supported RAID features include RAID levels 0, 1, 5, and 6, RAID spans 10, 50
20 and 60, online capacity expansion (OCE), online RAID level migration (RLM),
21 auto resume after loss of system power during arrays, array rebuild or
22 reconstruction (RLM) and configurable stripe size up to 1MB. Additional
23 supported RAID features include check consistency for background data
24 integrity, patrol read for media scanning and repairing, 64 logical drive
25 support, up to 64TB LUN support, automatic rebuild and global and dedicated hot
30 The \fBmega_sas.conf\fR file contains no user configurable parameters. Please
31 configure your hardware through the related BIOS utility or the MegaCli
32 configuration utility. If you want to install to a drive attached to a
33 mega_sas HBA, you should create the virtual drive first from the BIOS before
34 running the Solaris install. You can obtain the MegaCli utility from the LSI
38 The \fBmega_sas\fR device can support up to 64 virtual disks. Note that BIOS
39 numbers the virtual disks as 1 through 64, however in the Solaris operating
40 environment virtual disks are numbered from 0 to 63. Also note that SAS and
41 SATA drives cannot be configured into the same virtual disk.
42 .SH KNOWN PROBLEMS AND LIMITATIONS
45 The \fBmega_sas\fR driver does not support the LSI MegaRAID SAS 8204ELP,
46 8204XLP, 8208ELP, and 8208XLP controllers.
