NAME

6       mega_sas - SCSI HBA driver for LSI MegaRAID SAS controller
7

DESCRIPTION

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.
15
16
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.

CONFIGURATION

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.
33
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.
40

KNOWN PROBLEMS AND LIMITATIONS

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