DESCRIPTION
The imraid_sas MegaRAID FALCON SAS2.0 controller host bus adapter
driver is a SCSA-compliant nexus driver that supports the LSI MegaRAID
FALCON SAS 92xx series of controllers.
FALCON HBA supports up to 64 JBOD drives which are directly exposed to
OS.
Some of the RAID Features include the following:
o RAID levels 0, 1, and 5
o RAID spans 10
o Online Capacity Expansion (OCE)
o Online RAID Level Migration (RLM)
o Auto resume after loss of system power during array rebuild
or reconstruction (RLM)
o Configurable stripe size up to 64KB
o Check Consistency for background data integrity
o Patrol read for media scanning and repairing
o 16 logical drive support
o Automatic rebuild
o Global and dedicated Hot Spare support
The imraid_sas.conf file consists a user tunable parameter to configure
MSI or MSI-X support in the imraid_sas driver. Pre-boot applications or
MegaCli can be used to configure the HBA. The MegaCli utility can be
downloaded from the LSI website. To install the operating system on the
drives attached to the FALCON HBA, either creates a virtual drive or a
JBOD drive from the pre-boot application.
The LSI MegaRAID FALCON SAS device can support up to 16 virtual
SAS2.0, SAS1.0, SATA3.0, or SATA 6.0 disks. The BIOS numbers the vir‐
tual disks as 1 through 16. In Solaris these drives are numbered from
0 to 15.

NOTES
JBOD drives do not qualify for any of the RAID processing.
The imraid_sas driver only supports internal and external expanders
that are not fully SAS1.0 or fully SAS2.0 compliant.
