Others looks like being real driver but we haven’t used them yet. Write journaling, which allows automatic synchronization of potentially inconsistent data after unexpected power-down situations. IM volumes have two mirrored disks; IME volumes have three to ten mirrored disks. If a disk in an Integrated Mirroring volume fails, the hot swap capability allows you to restore the volume by simply swapping disks. In fact, I must admit all my “something-status” packages for others kind of cards are based on this work. Host-based status software monitors the state of the mirrored disks and reports any error conditions. When the firmware is initialized, each member disk is queried to read the stored metadata in order to verify the configuration.

An opensource reporting tool named mpt-status has been developped. Mirrored volumes run in optimal mode or in degraded mode if one mirrored disk fails.

The current Media Verification Lssi Block Address is written to nonvolatile memory occasionally to allow media verification to continue approximately where it left off prior to a power-cycle. The firmware re-synchronizes all hot-swapped disks that have been removed, even if the same disk is re-inserted. A proprietary management tool also exists, see below.

If disk write caching were enabled not recommendedthe disk write log fusioh be invalid. BIOS upgrade from lis Linux system. SMART is a technology that monitors hard disk drives for signs of future disk failure and generates an alert if such signs are detected.

Running mpt-status without any parameters will give you the same output example as above. In a two-disk mirrored volume, the firmware marks the hot-swapped disk as the secondary disk and marks the other mirrored disk as the primary disk.

Somes seems to be required dependencies.

The firmware detects hot swap removal and disk insertion. Write journaling, which allows automatic synchronization of potentially inconsistent data after unexpected power-down situations. If the firmware fails one of the mirrored disks, it automatically replaces the failed disk with a hot-spare disk and then re-synchronizes the mirrored data.

This includes reading the Fusion-MPT configuration to access the parameters that are used to define behavior between the SAS controller and the lei connected to it. IM volumes have two mirrored disks; IME volumes have three to ten mirrored disks.

On Debian based system, simply run:. The firmware re-synchronizes all data from the primary disk gusion the new secondary disk. The two volumes can have up to twelve disk drives total, plus one or two hot-spare disks.

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:. Metadata used to store volume configuration on mirrored disks.

The firmware is automatically notified when the failed disk has been replaced, and it then designates the failed disk as the new hot-spare. The hot-spares are in addition to the disk maximum for two volumes per SAS controller.

The firmware supports hot swapping. The packages comes with an initscript that periodic mlt mpt-status to check status. Re-synchronization is attempted after a hot-spare is activated due to a physical device failure, or after a hot swap has occurred to a physical disk fsuion the volume.

Host-based status software monitors the state of the mirrored disks and reports any error conditions. If a disk in an Integrated Mirroring volume fails, the hot swap lai allows you to restore the volume by simply swapping disks. An IME volume can be configured with up to ten mirrored disks.

The IM and IME features provide a robust, high-performance, fault-tolerant solution to data storage needs. Even it’s not full of features theses card appear to work fine and are supported by an opensource Linux driver. One or lzi global hot-spares can be added also. The hot-swapped disk is automatically re-synchronized in the background, without any host or user intervention. On the other hand, performance is actually improved during reads. Powered by Trac 1.

When the firmware is initialized, each member disk is queried to read the stored metadata in order to verify the configuration.
