MR_SAS(7D)MR_SAS(7D)NAMEmr_sas - LSI MegaRAID SAS2.0 Controller HBA driver
DESCRIPTION
The mr_sas MegaRAID SAS2.0 controller host bus adapter driver is a
SCSA-compliant nexus driver that supports the LSI MegaRAID SAS 92xx
series of controllers and the Sun StorageTek 6Gb/s SAS RAID HBA series
of controllers.
Some of the RAID Features include the following:
o RAID levels 0, 1, 5, and 6
o RAID spans 10, 50, and 60
o Online Capacity Expansion (OCE)
o Online RAID Level Migration (RLM)
o Auto resume after loss of system power during arrays array
rebuild or reconstruction (RLM)
o Configurable stripe size up to 1MB
o Check Consistency for background data integrity
o Patrol read for media scanning and repairing
o 64 logical drive support
o Up to 64TB LUN support
o Automatic rebuild
o Global and dedicated Hot Spare support
Configuration
The mr_sas.conf file contains one user configurable parameter, for MSI
or MSI-X support. Configure your hardware through the related BIOS
utility or the MegaCli Configuration Utility. If you want to install to
a drive attached to a mr_sas HBA, create the virtual drive first from
the BIOS (X86) before running Solaris install. The MegaCli utility can
be downloaded from the LSI website.
The LSI MegaRAID SAS device can support up to 64 virtual SAS2.0,
SAS1.0, SATA3.0, or SATA 6.0 disks. The BIOS numbers the virtual disks
as 1 through 64, however in Solaris these drives are numbered from 0 to
63. Also keep in mind that SAS and SATA drives can not be configured
into the same virtual disk.
