NAME
mfi - LSI MegaRAID SAS driverSYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:device pci device 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.
HARDWARE
The driver supports the following hardware:- LSI MegaRAID SAS 8408E
- LSI MegaRAID SAS 8480E
- Dell PERC5/i
