LSI Fusion MPT SAS
1. Card information
The FusionMPT SAS2 is a low-end card from LSI. It replaces the Fusion MPT cards.
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.
Even it's not full of features theses card appear to work fine and are supported by an opensource Linux driver.
A proprietary monitoring tool is available but it's nearly offer no management features.
2. Linux kernel drivers
|mpt2sas||LSI FusionMPT SAS 2.0 cards|
There are many more mpt* drivers in Linux kernel.
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 : LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 02) Dell PERC H200
3. Management and reporting tools
There are no management tool. LSI doesn't provide any proprietary utility for FusionMPT's cards.
However an opensource reporting tool named mpt-status has been developped.
3.1.1. Quickstart and output example
Probe controllers IDs:
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":
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.
Load it by hand for the first time and add it to /etc/modules for next reboots:
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.
We experienced several disks failure on MPT SAS controllers and mpt-status always reported the failure and status changes.
However don't expected verbose output.
3.1.3. Reporting with mpt-status
mpt-status has been greatly integrated to Debian by Petter Reinholdtsen and Steffen Joeris.
Many thanks to them for good work !
The packages comes with an initscript that periodic run mpt-status to check status.
It keeps a file with latest status and thus is able to detect RAID status changes and/or brokeness.
It will log a ligne to syslog when something failed and will send you a mail.
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.
This tool comes from LSI. Its sources (for Linux systems) are available but the license is not specified.
I haven't use it much, so here is a quick example of what it can do:

4. BIOS upgrade from a Linux system
Sorry, we don't have any informations about this.
