LSI Logic Fusion-MPT Message Passing
Interface II
SYNOPSIS
mpii* at pci? dev ? function ?
DESCRIPTION
Thempii driver provides support for storage controllers
using the LSI Logic Fusion-MPT Message Passing Interface II family of
chipsets:
- LSISAS2004, LSISAS2008, LSISAS2108, LSISAS2208, LSISAS2216, LSISAS2308, LSISAS3004, LSISAS3008, LSISAS3108, LSISAS3408, LSISAS3416, LSISAS3508, LSISAS3516
These chipsets can be found on the following controllers:
- Dell PERC H200, HBA330, 12Gbps SAS HBA
- IBM ServeRAID H1110
- Lenovo N2215, ThinkSystem 430
- LSI SAS 9200-8e, SAS 9207-8i, SAS 9211-4i, SAS 9211-8i
- Broadcom SAS 9300, HBA 9400
Some models of these controllers carry an Integrated RAID (IR) firmware providing support for RAID 0, RAID 1, RAID10 or RAID5 using SAS or SATA drives. All RAID configuration is done through the controllers' BIOSes.
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.

HISTORY
The mpii driver first appeared in
OpenBSD 4.7. NetBSD support
was added in NetBSD 6.0.
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.
