LSI (Engenio) RAID Engines

Top Previous Next

LSI (previously Engenio Information Technologies, Inc.) sells RAID subsystems both under the LSI brand, as well as into the channel where other manufacturers (or VARs) re brand it as their own. As such, you might have a RAID subsystem that uses a supported LSI engine and might not know it.

The dump below is from an IBM 1742 RAID subsystem, which has a supported LSI engine. As is the case with the Infortrend RAID engine, entering the -I+ will report extended SCSI inquiry information along with vendor-unique information which describes the device in more detail. If you just send the -I command for basic inquiry information, the software will not attempt to discern whether or not device you selected has an LSI RAIDengine, and Infortrend RAID engine, or some other RAID device.

The -z option sends the vendor-unique commands to query the subsystem and report information on the physical disks in the subsystem. The example below shows the data returned by the -z portion in RED. The -I+ results are in blue. The data in black will be returned regardless of the engine type (assuming the device is fibre channel, SCSI, or USB host-attach interface). You can choose to enter the -I+ without the -z or the -z without the I+.

Usage

smartmon-ux -I+ -z

Example

# ./smartmon-ux -z -I+ /dev/sg3

If the selected device is a LUN that is presented by a RAID subsystem with an Infortrend controller in it, you will get the output that is highlighted in Blue. If it is not an Infortrend controller, the software will report the EVPD data described in the Inquiry Page Viewersection.

Additional Information

•	Unless you (or your RAID provider) has configured the engine otherwise, you can query this RAID engine by sending the -I+ and -z command to any LUN.

•	Significantly more information will be made available in future releases.

•	RAID subsystem manufacturers and VARs/OEMs mask the make & model of RAID engine they are using by changing the make and model fields. You may have a LSI-based subsystem and not know it.

•	By design, our software does NOT allow you to change any configurable parameters except for mode pages. You cannot use our software as a "configurator".

•	If you send the -z command to a device which is not a logical disk associated with a Mylex (or Infortrend) RAID engine, the device will reject the command and our software will just reject the command.

•

We support reporting all LSI defined physical device states. The values that may be returned are shown in the LSI Drive Status Definitions table below. The state is shown between braces, so a drive in Optimal state will be reported as [Optimal] and Out of Service will be reported as [Out-of-Service].

LSI Drive Status Definitions

Status String	Meaning
Optimal	The drive is in good condition and is currently configured as part of a LUN or global hot spare.
Unassigned	The controller has detected a drive present, but the drive is not part of a configured logical unit.
Failed-CauseUnknown	Failed by alternate controller for reasons unknown. You must replace the drive.
Replaced	The controller has detected the replacement of a failed drive through a hot swap or an action from the host management software.
Wrong Drive Removed	The controller detected that a drive location which previously had an optimal drive now does not have a drive installed. Although there are other cases that can cause this error, the most likely is that the incorrect drive was removed or replaced by the user.
Out-of-Service	The drive was in a drive group that experienced an error during interrupted write processing that caused the LUN to transition to a DEAD state. Drives in the group that are in this state did not experience the error.
Failed-ReadFailure	Failed due to inability of drive to satisfy the read. You must replace the drive.
Wrong-Block-Size	The mode page for block size is improperly set. You may be able to resolve this with SANtools' mode page editor function.
Reserved-Status	Reserved for future use by RAID engine.
Failed-or-Missing	The drive does not respond. You must replace the drive.
Capacity<Minimum	The replaced drive does not have sufficient capacity to accommodate all of the LUNs in the drive group.
Failed-FormatFailure	Write error while formatting. You must replace the drive.
Failed-WriteFailure	Write error. You must replace the drive.
Failed-ByUser	Failed due to user command.
Offline-ByUser	The drive was in a drive group that has been marked offline by the user. The LUN will transition to the DEAD state. All of the drives in the group will report this status.
Failed-ControllerStorage	Failed by controller. You must replace the drive.
Non-Existent	Note: Drives in this state are ignored by SANtools. Nothing will be reported for the Channel/ID combination.
