.Sh SYNOPSIS
|
|
.Cd "mpii* at pci? dev ? function ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for storage controllers using the
|
|
LSI Logic Fusion-MPT Message Passing Interface II
|
|
family of chipsets:
|
|
.Pp
|
|
.Bl -dash -offset indent -compact
|
|
.It
|
|
LSISAS2004,
|
|
LSISAS2008
|
|
.El
|
|
.Pp
|
|
These chipsets can be found on the following controllers:
|
|
.Pp
|
|
.Bl -dash -offset indent -compact
|
|
.It
|
|
Dell PERC H200
|
|
.It
|
|
LSI SAS 9200-8e, SAS 9211-4i, SAS 9211-8i
|
|
.El
|
|
.Pp
|
|
Some models of these controllers have varying degrees of support for RAID 0
|
|
and RAID 1.
|
|
.Pp
|
|
.Nm
|
|
supports monitoring of the logical disks in the controller through the
|
|
.Xr bioctl 8
|
|
and
|
|
.Xr envstat 8
|
|
commands.
|
|
.Sh EVENTS
|
|
The
|
|
.Nm
|
|
driver is able to send events to
|
|
.Xr powerd 8
|
|
if a logical drive in the controller is not online.
|
|
The
|
|
.Em state-changed
|
|
event will be sent to the
|
|
.Pa /etc/powerd/scripts/sensor_drive
|
|
script when such condition happens.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in
|
|
.Ox 4.7 .
|
|
.Sh AUTHORS
|
|
.An -nosplit
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An James Giannoules
|
|
and
|
|
.An Mike Belopuhov .
|
|
.Sh BUGS
|
|
The chips supported by
|
|
.Nm
|
|
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.
