6 mega_sas - SCSI HBA driver for LSI MegaRAID SAS controller
7
9 The mega_sas MegaRAID controller host bus adapter driver is a SCSA-
10 compliant nexus driver that supports the Dell PERC 5/E, 5/i, 6/E and
11 6/i RAID controllers, the IBM ServeRAID-MR10k SAS/SATA controller and
12 the LSI MegaRAID SAS/SATA 8308ELP, 8344ELP, 84016E, 8408ELP, 8480ELP,
13 8704ELP, 8704EM2, 8708ELP, 8708EM2, 8880EM2 and 8888ELP series of con‐
14 trollers.

17 Supported RAID features include RAID levels 0, 1, 5, and 6, RAID spans
18 10, 50 and 60, online capacity expansion (OCE), online RAID level
19 migration (RLM), auto resume after loss of system power during arrays,
20 array rebuild or reconstruction (RLM) and configurable stripe size up
21 to 1MB. Additional supported RAID features include check consistency
22 for background data integrity, patrol read for media scanning and
23 repairing, 64 logical drive support, up to 64TB LUN support, automatic
24 rebuild and global and dedicated hot spare support.

27 The mega_sas.conf file contains no user configurable parameters. Please
28 configure your hardware through the related BIOS utility or the MegaCli
29 configuration utility. If you want to install to a drive attached to
30 a mega_sas HBA, you should create the virtual drive first from the BIOS
31 before running the Solaris install. You can obtain the MegaCli utility
32 from the LSI website.

34
35 The mega_sas device can support up to 64 virtual disks. Note that BIOS
36 numbers the virtual disks as 1 through 64, however in the Solaris oper‐
37 ating environment virtual disks are numbered from 0 to 63. Also note
38 that SAS and SATA drives cannot be configured into the same virtual
39 disk.

42 The mega_sas driver does not support the LSI MegaRAID SAS 8204ELP,
43 8204XLP, 8208ELP, and 8208XLP controllers.
