mega_sas(7D) Devices mega_sas(7D)NAMEmega_sas - SCSI HBA driver for LSI MegaRAID SAS controller
DESCRIPTION
The mega_sas MegaRAID controller host bus adapter driver is a SCSA-com‐
pliant nexus driver that supports the Dell PERC 5/E, 5/i, 6/E and 6/i
RAID controllers, the IBM ServeRAID-MR10k SAS/SATA controller and the
LSI MegaRAID SAS/SATA 8204, 8208, 8308, 84016, 8704, 8708, 8300, 8708,
8408, 8480, 8344, 8880 and 8888 series of controllers.
Supported RAID features include RAID levels 0, 1, 5, and 6, RAID spans
10, 50 and 60, online capacity expansion (OCE), online RAID level
migration (RLM), auto resume after loss of system power during arrays,
array rebuild or reconstruction (RLM) and configurable stripe size up
to 1MB. Additional supported RAID features include check consistency
for background data integrity, patrol read for media scanning and
repairing, 64 logical drive support, up to 64TB LUN support, automatic
rebuild and global and dedicated hot spare support.
CONFIGURATION
The mega_sas.conf file contains no user configurable parameters. Please
configure your hardware through the related BIOS utility or the MegaCli
configuration utility. If you want to install to a drive attached to
a mega_sas HBA, you should create the virtual drive first from the BIOS
before running the Solaris install. You can obtain the MegaCli utility
from the LSI website.
The mega_sas device can support up to 64 virtual disks. Note that BIOS
numbers the virtual disks as 1 through 64, however in the Solaris oper‐
ating environment virtual disks are numbered from 0 to 63. Also note
that SAS and SATA drives cannot be configured into the same virtual
disk.
