mfi -- LSI Logic & Dell MegaRAID SAS RAID controller SYNOPSIS
mfi* at pci? dev ? function ? DESCRIPTION
The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including: - Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i - Intel RAID Controller SRCSAS18E, SRCSAS144E - LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i - IBM ServeRAID M1015, ServeRAID M5014 These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives. Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done through the controllers' BIOSes. mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands. EVENTS
The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online. The state-changed event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens. SEE ALSO
intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8), powerd(8) HISTORY
The mfi driver first appeared in NetBSD 4.0. BSD

mfi -- LSI MegaRAID SAS driver SYNOPSIS
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.conf(5): 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 pro- vided via /dev/mfid? device nodes. A simple management interface is also provided on a per-controller basis via the /dev/mfi? device node. The mfi 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 mfi 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 mfi driver supports the following hardware: o LSI MegaRAID SAS 1078 o LSI MegaRAID SAS 8408E o LSI MegaRAID SAS 8480E o LSI MegaRAID SAS 9260 o Dell PERC5 o Dell PERC6 o IBM ServeRAID M5015 SAS/SATA o IBM ServeRAID-MR10i o Intel RAID Controller SROMBSAS18E FILES
/dev/mfid? array/logical disk interface /dev/mfi? management interface DIAGNOSTICS
mfid%d: Unable to delete busy device An attempt was made to remove a mounted volume. SEE ALSO
amr(4), pci(4), mfiutil(8) HISTORY
The mfi driver first appeared in FreeBSD 6.1. AUTHORS
The mfi driver and this manual page were written by Scott Long <>. BUGS
The driver does not support big-endian architectures at this time. BSD
