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:
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.

HISTORY

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.
