NAME

6       mr_sas - LSI MegaRAID SAS2.0 Controller HBA driver
7

DESCRIPTION

9       The  mr_sas  MegaRAID  SAS2.0  controller  host bus adapter driver is a
10       SCSA-compliant nexus driver that supports the  LSI  MegaRAID  SAS  92xx
11       series  of controllers and the Sun StorageTek 6Gb/s SAS RAID HBA series
12       of controllers.
13
14
15       Some of the RAID Features include the following:
16
17           o      RAID levels 0, 1, 5, and 6
18
19           o      RAID spans 10, 50, and 60
20
21           o      Online Capacity Expansion (OCE)
22
23           o      Online RAID Level Migration (RLM)
24
25           o      Auto resume after loss of system power during  arrays  array
26                  rebuild or reconstruction (RLM)
27
28           o      Configurable stripe size up to 1MB
29
30           o      Check Consistency for background data integrity
31
32           o      Patrol read for media scanning and repairing
33
34           o      64 logical drive support
35
36           o      Up to 64TB LUN support
37
38           o      Automatic rebuild
39
40           o      Global and dedicated Hot Spare support
41
42   Configuration
43       The  mr_sas.conf file contains one user configurable parameter, for MSI
44       or MSI-X support. Configure your  hardware  through  the  related  BIOS
45       utility or the MegaCli Configuration Utility. If you want to install to
46       a drive attached to a mr_sas HBA, create the virtual drive  first  from
47       the  BIOS (X86) before running Solaris install. The MegaCli utility can
48       be downloaded from the LSI website.
49
50
51       The LSI MegaRAID SAS device  can  support  up  to  64  virtual  SAS2.0,
52       SAS1.0,  SATA3.0, or SATA 6.0 disks. The BIOS numbers the virtual disks
53       as 1 through 64, however in Solaris these drives are numbered from 0 to
54       63.  Also  keep  in mind that SAS and SATA drives can not be configured
55       into the same virtual disk.
