[[TOC(depth=-1)]] = LSI Fusion MPT SAS2 = [[Image(wiki:LSI:logo_lsi.gif)]] [[BR]][[BR]] = 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's no opensource tool for theses new cards. [[BR]]However, LSI provide a '''command line management tool''' named sas2ircu. Management features are really '''basic''', so it's better to use is as a '''reporting tool''' only. == 3.1. sas2ircu == === 3.1.1.

It includes a python wrapper around tw_cli command and an initscript which daemonize the launch of the wrapper.[[BR]] It also handles failure detection and report it by mail and syslog. It also handle unexpected output changes and reminders until the status is fine again.
