• LSI 9285-8e and Supermicro SC837E26-RJBOD1 duplicate enclosure ID and slot numbers

  - by Andy Shinn

  I am working with 2 x Supermicro SC837E26-RJBOD1 chassis connected to a single LSI 9285-8e card in a Supermicro 1U host. There are 28 drives in each chassis for a total of 56 drives in 28 RAID1 mirrors. The problem I am running in to is that there are duplicate slots for the 2 chassis (the slots list twice and only go from 0 to 27). All the drives also show the same enclosure ID (ID 36). However, MegaCLI -encinfo lists the 2 enclosures correctly (ID 36 and ID 65). My question is, why would this happen? Is there an option I am missing to use 2 enclosures effectively? This is blocking me rebuilding a drive that failed in slot 11 since I can only specify enclosure and slot as parameters to replace a drive. When I do this, it picks the wrong slot 11 (device ID 46 instead of device ID 19). Adapter #1 is the LSI 9285-8e, adapter #0 (which I removed due to space limitations) is the onboard LSI.

After getting in contact with a very knowledgeable Supermicro tech, they provided us with a tool called Xflash (doesn't appear to be readily available on their FTP). When we gathered some information using this utility, my colleague found something very strange: root@mogile2 test]# ./xflash.dat -i get avail Initializing Interface. Expander: SAS2X36 (SAS2x36) 1) SAS2X36 (SAS2x36) (50030480:00EE917F) (0.0.0.0) 2) SAS2X36 (SAS2x36) (50030480:00E9D67F) (0.0.0.0) 3) SAS2X36 (SAS2x36) (50030480:0112D97F) (0.0.0.0) This lists the connected enclosures. You see the 3 connected (we have since added a 3rd and a 4th which is not yet showing up) with their respective SAS address / WWN (50030480:00EE917F). Now we can use this address to get information on the individual enclosures: [root@mogile2 test]# ./xflash.dat -i 5003048000EE917F get exp Initializing Interface. Expander: SAS2X36 (SAS2x36) Reading the expander information..........

The first 2 enclosures logical ID is partially masked out where the 3rd one (which has a correct unique enclosure ID) is not. We pointed this out to Supermicro and were able to confirm that this address is supposed to be set during manufacturing and there was a problem with a certain batch of these enclosures where the logical ID was not set. We believe that the RAID controller is determining the ID based on the logical ID and since our first 2 enclosures have the same logical ID, they get the same enclosure ID. We also confirmed that 0000007F is the default which comes from LSI as an ID. The next pointer that helps confirm this could be a manufacturing problem with a run of JBODs is the fact that all 6 of the enclosures that have this problem begin with 00E. I believe that between 00E8 and 00EE Supermicro forgot to program the logical IDs correctly and neglected to recall or fix the problem post production. Fortunately for us, there is a tool to manage the WWN and logical ID of the devices from Supermicro: ftp://ftp.supermicro.com/utility/ExpanderXtools_Lite/. Our next step is to schedule a shutdown of these JBODs (after data migration) and reprogram the logical ID and see if it solves the problem. Update 06/28/12 #2: I just discovered this FAQ at Supermicro while Google searching for "lsi 0000007f": http://www.supermicro.com/support/faqs/faq.cfm?faq=11805. I still don't understand why, in the last several times we contacted Supermicro, they would have never directed us to this article :\

• Including configuration files while compiling a Flex application with MXMLC

  - by Daniel

  Hello there, I'm using: - Flex SDK 3.5.0 - Parsley 2.2.2. - Flash Builder 4 Down in my src folder (which is configured as part of the source path in the Flash Builder), I have a logging.xml which I configure via Parsley: FlexLoggingXmlSupport.initialize(); XmlContextBuilder.build("com/company/product/util/log/logging.xml"); When I run my application through Flash Builder, the XmlContentBuilder seems to locate the logging.xml (the implementation is a regular URLLoader one). When I compile my application using MXMLC (whether in Ant or command-line), and then run the swf, I get the following error: Cause(0): Error loading com/company/product/util/log/logging.xml: Error in URLLoader - cause: Error #2032: Stream Error. URL: file:///C|/workspace/folder01/product/target/com/company/product/util/log/logging.xml - cause: Error #2032: Stream Error. URL: file:///C|/workspace/folder01/product/target/com/company/product/util/log/logging.xml Here is the MXMLC tag in Ant: <mxmlc file="${product.src.dir}/com/company/product/view/Main.mxml" output="${product.target.dir}/${product.release.filename}" keep-generated-actionscript="false"> <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml" /> <!-- source paths --> <source-path path-element="${FLEX_HOME}/frameworks" /> <compiler.source-path path-element="${product.src.dir}" /> <compiler.source-path path-element="${product.locale.dir}/{locale}" /> <compiler.library-path dir="${product.basedir}" append="true"> <include name="libs" /> </compiler.library-path> <warnings>false</warnings> <debug>false</debug> </mxmlc> And here is the command line: \mxmlc.exe -output "C:\temp\Rap.swf" -load-config "C:\Program Files\Adobe\Adobe Flash Builder 4 Plug-in\sdks\3.5.0\frameworks\flex-config.xml" -source-path "C:\Program Files\Adobe\Adobe Flash Builder 4 Plug-in\sdks\3.5.0\frameworks" C:\workspace\folder01\product\src C:\workspace\folder01\product\locale\en_US -library-path+=C:\workspace\folder01\product\libs -file-specs C:\workspace\folder01\product\src\com\company\product\view\main.mxml Now perhaps I don't get this correctly, but as far as I understand the SWF should be compiled with all of the resources in the paths I give MXMLC as source-paths. For some reason it seems that the XML file is not compiled into the SWF, hence the relative path of the XmlContentBuilder isn't located successfully. I could not find any argument to provide the MXMLC with that might solve this. I tried using the -dump-config option with the Flash Builder's compiler, then giving that configuration to MXMLC, but it didn't work either. I tried providing the XmlContentBuilder with an absolute path. That worked fine when I compiled with MXMLC via Ant, but still didn't work when I used MXMLC in the command-line... I'd be happy to be enlightened here, regarding all subjects - using MXMLC, accessing resources with relative paths, configuring logging in Parsley, etc. Many thanks in advance, Daniel

• Ball bouncing at a certain angle and efficiency computations

  - by X Y

  I would like to make a pong game with a small twist (for now). Every time the ball bounces off one of the paddles i want it to be under a certain angle (between a min and a max). I simply can't wrap my head around how to actually do it (i have some thoughts and such but i simply cannot implement them properly - i feel i'm overcomplicating things). Here's an image with a small explanation . One other problem would be that the conditions for bouncing have to be different for every edge. For example, in the picture, on the two small horizontal edges i do not want a perfectly vertical bounce when in the middle of the edge but rather a constant angle (pi/4 maybe) in either direction depending on the collision point (before the middle of the edge, or after). All of my collisions are done with the Separating Axes Theorem (and seem to work fine). I'm looking for something efficient because i want to add a lot of things later on (maybe polygons with many edges and such). So i need to keep to a minimum the amount of checking done every frame. The collision algorithm begins testing whenever the bounding boxes of the paddle and the ball intersect. Is there something better to test for possible collisions every frame? (more efficient in the long run,with many more objects etc, not necessarily easy to code). I'm going to post the code for my game: Paddle Class public class Paddle : Microsoft.Xna.Framework.DrawableGameComponent { #region Private Members private SpriteBatch spriteBatch; private ContentManager contentManager; private bool keybEnabled; private bool isLeftPaddle; private Texture2D paddleSprite; private Vector2 paddlePosition; private float paddleSpeedY; private Vector2 paddleScale = new Vector2(1f, 1f); private const float DEFAULT_Y_SPEED = 150; private Vector2[] Normals2Edges; private Vector2[] Vertices = new Vector2[4]; private List<Vector2> lst = new List<Vector2>(); private Vector2 Edge; #endregion #region Properties public float Speed { get {return paddleSpeedY; } set { paddleSpeedY = value; } } public Vector2[] Normal2EdgesVector { get { NormalsToEdges(this.isLeftPaddle); return Normals2Edges; } } public Vector2[] VertexVector { get { return Vertices; } } public Vector2 Scale { get { return paddleScale; } set { paddleScale = value; NormalsToEdges(this.isLeftPaddle); } } public float X { get { return paddlePosition.X; } set { paddlePosition.X = value; } } public float Y { get { return paddlePosition.Y; } set { paddlePosition.Y = value; } } public float Width { get { return (Scale.X == 1f ?

} Thanks in advance for any tips on the 4 issues. EDIT1: Something isn't working properly. The collision axis doesn't come out right and the interpolation also seems to have no effect.

So instead of (-1,0) i get the (1,0) (this happened even before i multiplied with -1 there). Sometimes there isn't even a collision registered even though the ball passes through the paddle... The interpolation also seems to have no effect as the angles barely change (or the overlapAxis is almost never (-1,0) or (1,0) but something like (0.9783473, 0.02743843)... ). What am i missing here? :(

• Can't fix broken packages

  - by AWE

  I am too dumb but determined to use Ubuntu that I paid a professional to install it for me (dualboot 11.10 with Win7). When I came home I got a lot of things from the software center. Skype did not have a download button so I googled it and Ubuntu help told me to do this: sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" and then this: sudo apt-get update && sudo apt-get install skype The terminal told me "that this is potentially harmful..." but I thought it was Ubuntu language meaning "are you sure?" Now the computer is mute. Items cannot be installed or removed until the package catalog is repaired, so I want to repair it but the package operation fails. "sudo aptitude -f install" - command not found Synaptic package manager tells me that I have two broken packages, libc6 and libc6-dev so I do this: sudo apt-get update && sudo apt-get upgrade which tells me to do this: sudo apt-get -f install that ends up like this: Can't exec "locale": No such file or directory at /usr/share/perl5/Debconf/Encoding.pm line 16.

• BizTalk 2009 - SQL Server Job Configuration

  - by StuartBrierley

  Following the installation of Biztalk Server 2009 on my development laptop I used the BizTalk Server Best Practice Analyser which highlighted the fact that two of the SQL Server Agent jobs that BizTalk relies on were not running successfully.  Upon investigation it turned out that these jobs needed to be configured before they would run successfully. To configure these jobs open SQL Server Management Studio, expand SQL Server Agent > Jobs and double click on the appropriate job.  Select Steps and then edit the appropriate entries. Backup BizTalk Server (BizTalkMgmtDb) This job is comprised of three steps BackupFull, MarkAndBackupLog and ClearBackupHistory. BackupFull exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ The frequency here is set/left as daily The name is left as BTS You must provide a full destination path for the backup files to be stored. There are also two optional parameters: A flag that controls if the job forces a full backup if a partial backup fails A parameter to control the time of day to run the full backup; the default is midnight UTC time For example: exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ , 0, 22 MarkAndBackUpLog exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ You must provide a destination path for the log backups. Optionally you can also add an extra parameter that tells the procedure to use local time: exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ ,1 Clear Backup History exec [dbo].[sp_DeleteBackupHistory] @DaysToKeep=7 This will clear out the instances in the MarkLog table older than 7 days.    DTA Purge and Archive (BizTalkDTADb) This job is comprised of a single step. Archive and Purge exec dtasp_BackupAndPurgeTrackingDatabase 0, --@nLiveHours tinyint, 1, --@nLiveDays tinyint = 0, 30, --@nHardDeleteDays tinyint = 0, null, --@nvcFolder nvarchar(1024) = null, null, --@nvcValidatingServer sysname = null, 0 --@fForceBackup int = 0 Any completed instance that is older than the live days plus live hours will be deleted, as will any associated data. Any data older than the HardDeleteDays will be deleted - this means that those long running orchestration instances that would otherwise never be purged will at some point have their data cleared down while allowing the instance to continue, thus preventing the DTA databse from growing indefinitely.  This should always be greater than the soft purge window. The NVC folder is the path for the backup files, if this is null the job will not run failing with the error : DTA Purge and Archive (BizTalkDTADb) Job failed SQL Server Management Studio, job activity monitor, view history The @nvcFolder parameter cannot be null. Archive and Purge step How long you choose to keep instances in the Tracking Database is really up to you. For development I have set this up as: exec dtasp_BackupAndPurgeTrackingDatabase 0, 1, 30, ’<destination path>’, null, 0 On a live server you may want to adjust these figures: exec dtasp_BackupAndPurgeTrackingDatabase 0, 15, 20, ’<destination path>’, null, 0

• How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

  - by max

  I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?

• how to have 'find' not return the current directory

  - by Pinpin

  I'm currently trying to find (and copy) all files and folder structure matching a specific pattern, in a specified directory and I'm so nearly there! Specifically, I want to recursively copy all folders not begining with a '_' character from a specified path. find /source/path/with/directories -maxdepth 1 -type d ! -name _\* -exec cp -R {} /destination/path \; In the /source/path/with/directories/ path are machine-specific directories beginning with '_' and others, and I'm only interested in copying the others. For a reason beyond me, the find command returns the /source/path/with/directories/ directory, and therefore copies its content, directories begining with '_' included. Anyone have a hint as to why that is? Thanks, Pascal

• Installing javahl on Maverick

  - by Jason

  Hi all, I'm trying to get Subclipse working in Eclipse Galeilo, and to do that I have to install the JavaHL library. I installed the library using sudo apt-get install libsvn-java, but the eclipse.ini file has to be modified to take in the new library as an argument. First change to the ini file was -Djava.library.path=/usr/lib/jni/, which produced the errors "no libsvnjavahl-1 in java.library.path" "incompatible javahl library loaded. 1.3.x or later required." according to the install printout, version 1.6.12 was installed. So, I added libsvnjavahl-1.so to the file path above, and produced the following errors: "no libsvnjavahl-1 in java.library.path" "no svnjavahl-1 in java.library.path" "no svnjavahl in java.library.path" What's going on here?

• Is there a path of least resistance that a newcomer to graphics-technology-adoption can take at this point in the .NET graphics world?

  - by Rao

  For the past 5 months or so, I've spent time learning C# using Andrew Troelsen's book and getting familiar with stuff in the .NET 4 stack... bits of ADO.NET, EF4 and a pinch of WCF to taste. I'm really interested in graphics development (not for games though), which is why I chose to go the .NET route when I decided choose from either Java or .NET to learn... since I heard about WPF and saw some sexy screenshots and all. I'm even almost done with the 4 WPF chapters in Troelsen's book. Now, all of a sudden I saw some post on a forum about how "WPF was dead" in the face of something called Silverlight. I searched more and saw all the confusion going on at present... even stuff like "Silverlight is dead too!" wrt HTML5. From what I gather, we are in a delicate period of time that will eventually decide which technology will stabilize, right? Even so, as someone new moving into UI & graphics development via .NET, I wish I could get some guidance from people more experienced people. Maybe I'm reading too much? Maybe I have missed some pieces of information? Maybe a path exists that minimizes tears of blood? In any case, here is a sample vomiting of my thoughts on which I'd appreciate some clarification or assurance or spanking: My present interest lies in desktop development. But on graduating from college, I wish to market myself as a .NET developer. The industry seems to be drooling for web stuff. Can Silverlight do both equally well? (I see on searches that SL works "out of browser"). I have two fair-sized hobby projects planned that will have hawt UIs with lots of drag n drop, sliding animations etc. These are intended to be desktop apps that will use reflection, database stuff using EF4, networking over LAN, reading-writing of files... does this affect which graphics technology can be used? At some laaaater point, if I become interested in doing a bit of 3D stuff in .NET, will that affect which technologies can be used? Or what if I look up to the heavens, stick out my middle finger, and do something crazy like go learn HTML5 even though my knowledge of it can be encapsulated in 2 sentences? Sorry I seem confused so much, I just want to know if there's a path of least resistance that a newcomer to graphics-technology-adoption can take at this point in the graphics world.

• Has Windows 7 Fixed the 255 Character File Path Limit?

  - by The Matt

  As I understand it, the limitation of 255 characters in a file path is a Windows limitation. What is the reasoning for this? If so, has this been resolved in Windows 7? In our continuous integration practices, we often have deeply nested project structures and it would be extremely useful to be able to go beyond 255 characters. Right now we are somewhat forced to structure our projects in such a way as to not hit this artificial ceiling.
