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

These chipsets can be found on the following controllers:

-   Dell PERC H200

Some models of these controllers have varying degrees of support for RAID 0 and RAID 1.

AUTHORS
-nosplit 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.
