mpii

MPII(4) 						   BSD Kernel Interfaces Manual 						   MPII(4)

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:

	   -   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 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.
