Introduction
The goal of this project is to facilitate the continued development of the mega_sas driver in an OpenSolaris environment. The goals are to add FMA support, basic cfgadm support, and driver cleanup. Please report any bugs or other problems to the OpenSolaris storage-discuss Forum.
What's New
The following bugfix was putback to Build 105:

The following bugfixes were putback to Build 96:
- 6699664 mega_sas driver print warning messages at boot on some systems
- 6701042 megaraid_sas should use symbolic names rather than numbers
- 6708818 mega_sas driver should support the cfgadm command
- 6713140 mega_sas driver DEBUG kernel bootup messages are too verbose

The initial integration of the Solaris mega_sas driver is available in ONNV Build 88, with additional bugfixes in ONNV Build 90. Sun is releasing this code to the OpenSolaris community as an opportunity to learn about the code and contribute to its further development. There are some known limitations that are described in the "ONNV Heads-up : New SCSI HBA driver for LSI MegaRAID SAS Controller" announcement on the OS/Net Community Page.
mega_sas driver FMA support
The mega_sas driver FMA portfolio was approved on August 7th.
mega_sas Documentation
The LSI USER'S GUIDE for the MegaRAID SAS Software is available at the LSI download site. Note that for Solaris only the first 3 chapters apply, due to the MegaRAID Storage Manager not being ported to Solaris at this point in time.
How to get the mega_sas driver
The mega_sas driver is integrated into the latest Solaris Express Community Edition (SXCE). You can get the latest SXCE from the OpenSolaris web site downloads page.
