Overview

The mpii driver provides support for storage controllers using the LSI Logic Fusion-MPT Message Passing Interface II family of chipsets:

  • LSISAS2004, LSISAS2008, LSISAS2108, LSISAS2208, LSISAS2308, LSISAS3004, LSISAS3008, LSISAS3108, LSISAS3216, LSISAS3224, LSISAS3316, LSISAS3324, LSISAS3408, LSISAS3416, LSISAS3508, LSISAS3516, LSISAS3808, LSISAS3816, LSISAS3908, LSISAS3916

These chipsets can be found on the following controllers:

  • Dell PERC H200, HBA330, HBA345, HBA350, HBA355, 12Gbps SAS HBA

  • IBM ServeRAID H1110

  • Lenovo N2215, ThinkSystem 430, ThinkSystem 440

  • LSI SAS 9200-8e, SAS 9207-8i, SAS 9211-4i, SAS 9211-8i

  • Broadcom SAS 9300, HBA 9400, HBA 9500

  • Oracle SPARC T Series Platforms

  • Supermicro AOC-S3808, AOC-S3816

Some models of these controllers carry an Integrated RAID (IR) firmware providing support for RAID levels 0, 1, 1E, 5 or 10 using SAS or SATA drives. All RAID configuration is done through the controllers' BIOSes.

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.
