NAME
mfi
- LSI MegaRAID SAS driver
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device pcidevice mfi
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
mfi_load="YES"
DESCRIPTION
This driver is for LSI's next generation PCI Express SAS RAID controllers.
Access to RAID arrays (logical disks) from this driver is provided via
/dev/mfid?
device nodes.
A simple management interface is also provided on a per-controller basis via
the
/dev/mfi?
device node.
The
name is derived from the phrase "MegaRAID Firmware Interface", which is
substantially different than the old "MegaRAID" interface and thus requires
a new driver.
Older SCSI and SATA MegaRAID cards are supported by
amr(4)
and will not work with this driver.
Two sysctls are provided to tune the
driver's behavior when a request is made to remove a mounted volume.
By default the driver will disallow any requests to remove a mounted volume.
If the sysctl
dev.mfi.%d.delete_busy_volumes
is set to 1,
then the driver will allow mounted volumes to be removed.
