+
+= 1. Card information =
+
+The FusionMPT SAS2 is a low-end card from LSI. It replaces the Fusion MPT cards.
+[[BR]]It only supports RAID0 and RAID1 an can usually be found in many 1U rackmount servers which have only two disks drives. However, I must admit I'm not sure yet there's no RAID5 adapter with thoses chips.
+[[BR]]Even it's not full of features theses card appear to work fine and are supported by an '''opensource Linux driver'''.
+[[BR]]A proprietary monitoring tool is available but it's nearly offer '''no management features'''.
+
+[[BR]]
+= 2. Linux kernel drivers =
+
+|| Driver || Supported cards ||
+|| mpt2sas || LSI FusionMPT SAS 2.0 cards ||
+
+There are many more mpt* drivers in Linux kernel.
+[[BR]]Somes seems to be required dependencies. Others looks like being real driver but we haven't used them yet.
+
+''mpt2sas'' has been added to Linux kernel '''from 2.6.30 release'''. Thus, it should be available in all '''recent (2010+) Linux distributions'''.
+
+
+Some ''lspci -nn'' output examples:
+
+  * 01:00.0 Serial Attached SCSI controller [0107]: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 02) ''Dell PERC H200''
+[[BR]]
+= 3. Management and reporting tools =
+
+There are '''no management tool'''. LSI doesn't provide any proprietary utility for FusionMPT's cards.
+[[BR]]However an '''opensource reporting tool''' named ''mpt-status'' has been developped.
+
+== 3.1. mpt-status ==
+
+=== 3.1.1. Quickstart and output example ===
+
+Probe controllers IDs:[[BR]]
+{{{
+server:~# mpt-status -p
+Checking for SCSI ID:0
+Found SCSI id=0, use ''mpt-status -i 0`` to get more information.
+}}}
+
+Get status of controller "0":[[BR]]
+{{{
+server:~# mpt-status -i 0
+ioc0 vol_id 0 type IM, 2 phy, 73 GB, state OPTIMAL, flags ENABLED
+ioc0 phy 1 scsi_id 32 ATA      ST3808110AS      J   , 74 GB, state ONLINE, flags NONE
+ioc0 phy 0 scsi_id 1 ATA      ST3808110AS      J   , 74 GB, state ONLINE, flags NONE
+}}}
+
+In most case, your controller ID will be 0. Running ''mpt-status'' '''without any parameters''' will give you the same output example as above.
+
+You '''MUST''' have '''mptctl''' kernel module '''loaded''' to monitor your RAID HBAs.[[BR]]
+Load it by hand for the first time and add it to '''/etc/modules''' for next reboots:[[BR]]
+{{{
+modprobe mptctl
+echo mptctl >> /etc/modules
+}}}
+
+=== 3.1.2. My opinion about mpt-status ===
+
+Despite it seems that '''no real upstream development''' exists for this tool, it works '''fine''' and is '''reliable'''.
+[[BR]]We experienced several disks failure on MPT SAS controllers and mpt-status always reported the failure and status changes. [[BR]]However don't expected verbose output.
+
+Homepage: http://www.drugphish.ch/~ratz/mpt-status/
+
+=== 3.1.3. Reporting with mpt-status ===
+
+''mpt-status'' has been greatly integrated to Debian by '''Petter Reinholdtsen and Steffen Joeris'''.
+[[BR]]Many thanks to them for good work !
+
+The packages comes with an initscript that '''periodic''' run mpt-status to '''check status'''.
+[[BR]]It keeps a file with latest status and thus is able to detect RAID '''status changes and/or brokeness'''.
+[[BR]]It will log a ligne to '''syslog''' when something failed and will send you a '''mail'''.
+[[BR]]Until arrays are healthy again a '''reminder''' will be sent each 2 hours.
+
+In fact, I must admit all my ''"something-status"'' packages for others kind of cards are based on this work.
+
+== 3.2. lsiutil ==
+
+This tool comes from LSI. Its sources (for Linux systems) are available but the license is not specified.
+[[BR]]I haven't use it much, so here is a quick example of what it can do:
