mpii -- LSI Logic Fusion-MPT Message Passing Interface II
mpii* at pci? dev ? function ?
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, LSISAS2216, LSISAS2308, LSISAS3004, LSISAS3008, LSISAS3108, LSISAS3408, LSISAS3416, LSISAS3508, LSISAS3516 These chipsets can be found on the following controllers: - Dell PERC H200, HBA330, 12Gbps SAS HBA - IBM ServeRAID H1110 - Lenovo N2215, ThinkSystem 430 - LSI SAS 9200-8e, SAS 9207-8i, SAS 9211-4i, SAS 9211-8i - Broadcom SAS 9300, HBA 9400 Some models of these controllers carry an Integrated RAID (IR) firmware providing support for RAID 0, RAID 1, RAID10 or RAID5 using SAS or SATA drives. All RAID configuration is done through the controllers' BIOSes. mpii supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands.
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.

The mpii driver first appeared in OpenBSD 4.7. NetBSD support was added in NetBSD 6.0.
The mpii driver was written by James Giannoules and Mike Belopuhov.
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 sys- tem. 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. NetBSD 10.99 May 7, 2019 NetBSD 10.99
