mpii -- LSI Logic Fusion-MPT Message Passing Interface II
mpii* at pci? dev ? function ?
The mpii 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.
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.
bio(4), intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8),
The mpii driver first appeared in OpenBSD 4.7. NetBSD support was added
in NetBSD 6.0.
The mpii driver was written by James Giannoules and Mike Belopuhov.
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 sys-
tem. 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.
