7
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.

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)

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

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.

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.
