[[TOC(depth=-1)]] = LSI Fusion MPT SAS = [[Image(wiki:LSI:logo_lsi.gif)]] [[BR]][[BR]] = 1. Card information = The FusionMPT SAS is a low-end card from LSI. [[BR]]It only supports RAID0 and RAID1 an can usually be found in many 1U rackmount servers which have only two disks drives. [[BR]]Even it's not full of features theses card appear to work fine and are supported by an '''opensource Linux driver'''. [[BR]] An '''opensource monitoring software''' exists, as well as a proprietary management tool called ''lsiutil''. [[BR]] = 2. Linux kernel drivers = || Driver || Supported cards || || mptsas || LSI FusionMPT SAS cards || || mptctl || Driver to handle monitoring IOCTLs || 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. ''mptsas'' has been part of the mainstream Linux kernel for a while and should be '''available''' in all '''current Linux distributions'''. Some ''lspci -nn'' output examples: * 02:08.0 SCSI storage controller ![0100]: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS ![1000:0054] (rev 01) * 07:00.0 SCSI storage controller ![0100]: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS ![1000:0058] (rev 08) [[BR]] = 3. Management and reporting tools = An '''opensource reporting tool''' named ''mpt-status'' has been developped. A proprietary management tool also exists, see below. == 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: {{{ server:~# lsiutil LSI Logic MPT Configuration Utility, Version 1.56, March 19, 2008 1 MPT Port found Port Name Chip Vendor/Type/Rev MPT Rev Firmware Rev IOC 1. /proc/mpt/ioc0 LSI Logic SAS1068E B3 105 00143000 0 Select a device: [1-1 or 0 to quit] 1 1.
