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 Mes-
     sage 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 cur-
     rently 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.
