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. BSD
