Thank you in advanced,
I had a Buffalo DUO crap out on me that was setup as RAID 0. I dont belive it was the drives but rather the controller in the DUO unit. I bought another external HDD enclosure and was able to fireup the two older DUO drives in it and I think I resembled the RAID... (12 Replies)

One of my very old drive farm servers had an OS fault and can't boot now but I'd like to restore some files from it. I tried booting Ubuntu from a CD, but it couldn't see the drives -- possibly because they're RAIDed together. Is there a good way to get at my files?
The data in question is a... (2 Replies)

MFI(4) BSD Kernel Interfaces Manual MFI(4)
NAME
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.
