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. BSD

NAME
mpii -- LSI Logic Fusion-MPT Message Passing Interface II SYNOPSIS
mpii* at pci? dev ? function ? DESCRIPTION
The mpii driver provides support for storage controllers using the LSI Logic Fusion-MPT Message Passing Interface II family of chipsets: - LSISAS2004, LSISAS2008 These chipsets can be found on the following controllers: - Dell PERC H200 - LSI SAS 9200-8e, SAS 9211-4i, SAS 9211-8i Some models of these controllers have varying degrees of support for RAID 0 and RAID 1. mpii supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands. EVENTS
The mpii 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 mpii driver first appeared in OpenBSD 4.7. AUTHORS
The mpii driver was written by James Giannoules and Mike Belopuhov. BUGS
The chips supported by mpii do not use a SCSI-like identifier. Instead they use an opaque ID and leave discovery order up to the operating system. The code to handle this is currently not implemented and therefore it is not a good idea to run this driver on a multi-boot machine or with more than 1 drive. BSD
