I haven’t use it much, so here is a quick example of what it can do:. However don’t expected verbose output.

The firmware polls each physical disk in the volume at regular intervals. However, there is no data redundancy; therefore, if one disk fails, that data is lost.
Even it’s not full fusionm-pt features theses card appear to work fine and are supported by an opensource Linux driver.
The LSI Integrated Striping IS feature is useful for applications that require the faster performance and increased storage capacity of striping.

This tool comes from LSI. Running mpt-status without any parameters will give you the same output example as above. A proprietary management tool also exists, see below.
You can now try to run smartctl against one of the scsi generic devices you will have to figure out by yourself which one to use:. The IS feature writes data across multiple disks instead of onto one disk.

BIOS upgrade from a Linux system. It will log a ligne to syslog when something failed and will send you fusipn-mpt mail. The usable disk space for each IS member disk is adjusted down when the configuration is created, in order to leave room for this data. You fjsion-mpt to make sure SCSI generic device driver is loaded and will be loaded at boot. An opensource reporting tool named mpt-status has been developped.
However don’t expected verbose output. Download in other formats: On Debian based system, simply run:. Powered by Trac 1. T and such 4.
In general, striping is transparent to the BIOS, the drivers, and the operating system. Note – Fusio-mpt physical disks in a volume must be connected to the same SAS controller. IS provides better performance and more capacity than individual disks, without burdening the host CPU.
The packages comes lsl an initscript that periodic run mpt-status to check status. Until arrays are healthy again a reminder will be sent each 2 hours. SMART is a technology that monitors disk drives for signs of future disk failure and generates an alert if such signs are detected.

For example, as shown in FIGUREsegment 1 is written to disk 1, segment 2 is written to disk 2, segment 3 is written to disk 3, and so on. When the system reaches the end of the disk list, it ldi writing data at the next available segment of disk 1. Its sources for Linux systems are available but the license is not specified.
It includes these sections:. I haven’t use it much, so here fusipn-mpt a quick example of what it can do:. Despite it seems that no real upstream development exists for this tool, it works fine and is reliable. In most case, your controller ID will be 0. This includes reading the Fusion-MPT configuration to gain access to the parameters that are used to define behavior between the SAS controller and the devices connected to it.
Many thanks to them for good work!
