Oracle RAC with QFS shared storage going down when one disk fails

Hello,
I have an oracle RAC on my testing environment. The configuration follows
nodes: V210
Shared Storage: A5200
#clrg status
Group Name Node Name Suspended Status
rac-framework-rg host1 No Online
host2 No Online
scal-racdg-rg host1 No Online

/dev/md/racdg/dsk/d200 12 mr racfs -
When the disk /dev/did/dsk/d2 failed (I have failed it by removing from the array), the oracle RAC went offline on both nodes, and then both nodes paniced and rebooted. Now the #clrg status shows below output.

crs is not started in any of the nodes. I would like to know if anybody faced this kind of a problem when using QFS on diskgroup. When one disk is failed, the oracle is not supposed to go offline as the other disk is working, and also my qfs configuration is to mirror these two disks !!!!!!!!!!!!!!
Many thanks in advance
Ushas Symon

I'm not sure why you say QFS is mirroring these disks!?!? Shared QFS has no inherent mirroring capability. It relies on the underlying volume manager (VM) or array to do that for it. If you need to mirror you storage, you do it at the VM level by creating a mirrored metadevice.

  • How to implement RAC with no shared storage available...

    Hello Guys,
    I have installed, configured single node RAC R2 with 2 database instances on windows 2000 platform with the help of vmware software. Installation was successfull.
    I just meet my boss to explain him my acheivements and to get permission to go for prodcution environment where we will be developing 3 nodes RAC on linux platform.
    I asked him that we need a shared stroage system that can be achieved by SAN or NAS or firewire disks... but he refuses to buy any additioan hardware as we have already spend a lot on servers. He wants to me have another computer with a large size Hard Disk Drive to be used as shared storage.
    I just want to know can we configure 3 nodes RAC using HDD of an other computer as sommon shared storage...
    Please guide me. I really want to implement RAC in our production environment.
    Regards,
    Imran

    Yeah, but would openfiler work? Has any one
    implemented RAC using open filer or software
    configured shared storage.
    Any other better solution as i have to implement it
    in production environment and have to seek better
    backup facilities.Are you looking for a production environment, or an evaluation environment?
    For an evaluation environment OpenFiler works. I occasionally teach RAC classes using that. It works but it is not as fast or as robust as I'd like in production.
    For a production environment, plan to pay some money. The least expensive commercial shared stored I have found is from NetApp - any NetApp F8xx or FAS2xx files with iSCSI or even NFS license will do for RAC.

  • Oracle RAC with ASM install failure

    Hi Guy's
    I've just rebuilt an Oracle RAC system, i've built this system many times and have the build documented. I usually follow the build doc to the tee and everything works fine. I have now been asked to rebuild the system to go into the production evironment. This is a two server standard RAC setup using ASM. We have a HP MSA500 shared storage setup. I've run the cluster verification tool and all the checks have come out fine. Whilst installing the clusterware i get a failed error message whilst it try's to confiure the Oracle Clusterware Configuration Assistant.
    The error message i get is:
    Command = C:\Windows\system 32\cmd\C Call E:\Oracle\Product\10.2.0\crs\install\crssetup.config.bat
    PROT-1:Failed to intialize OCR Config
    STEP 1 Checking status of CRS cluster
    STEP 2 Creating directories (E:\Oracle\Product\10.2.0\Crs
    STEP 3 Configuring OCR repository
    ocr upgrade failed with (-1)
    I've done this build many times and never seen this error. From what i've read on the internet it looks like it could be something up with my shared storage but i dont know what.
    Any help would be greatly appreciated
    Thanks
    Lee

    try to apply ''dd' command against OCR & Voting disks to ensure that their headers are formatted 100% and contains no data from old installation:
    dd if=/dev/zero of=YOUR_OCR_DISK bs=1024 count=10000

  • SQLLoader issues of Oracle RAC with ASM

    One of our client wants to use Oracle RAC with ASM for our application, i just want to know if there would be any two-phased commit transactions and SQL*Loader issues in ASM.
    Database is Oracle 10g

    ASM works only at storage layer and has nothing to do with:
    - distributed transactions
    - client executable that connects to database instance: SQL*Loader, SQL*Plus, etc.
    RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances but still a single database; there is no need to use distributed transactions because you have a RAC database.

  • Does NFS support Oracle RAC with TAF ?

    Hi,
    Does NFS support Oracle RAC with TAF feature. ?
    If yes, please point to some valid document to prove the same.
    Regards
    Sumit

    TAF has nothing to do with the underlying storage architecture and is therefore 'supported' with your choice of asm, raw devices, cluster file system and NFS. NFS is supported on some platforms. For more details, check the certify tab in metalink. Some information can also be found here
    TAF will be available on any rac installation, but not all drivers support it (jdbc-thin for example)

  • Have new iMac with iPhoto sharing turned on. When the shared library is clicked the library disappears or starts to load then disappears? What is wrong?

    Have new iMac with iPhoto sharing turned on. When the shared library is clicked the library disappears or starts to load then disappears? What is wrong?

    Try this:  launch iPhoto with the Option key held down and create a new, test library.  Import some photos and check to see if the same problem persists. If it doesn't then your current library is damaged and needs repair.
    Therefore  make a temporary, backup copy (select the library and type Command+D) and  apply the two fixes below in order as needed:
    Fix #1
    Launch iPhoto with the Command+Option keys held down and rebuild the library.
    Since only one option can be run at a time start with Option #1, followed by #3 and then #4 as needed.
    Fix #2
    Using iPhoto Library Manager  to Rebuild Your iPhoto Library
    Download iPhoto Library Manager and launch.
    Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
    Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
    In the next  window name the new library and select the location you want it to be placed.
    Click on the Create button.
    Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
    If you experience the same problem with the test library then try this basic fix a try:  make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
         User/Home()/Library/ Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your
         User/Home()/Library/Caches/com.apple.iPhoto folder. 
    Click to view full size
    3 - launch iPhoto and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
    NOTE 2:  In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
    If that fails a reinstall of iPhoto is indicated. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder,
    Click to view full size
    Then install iPhoto from the source it came on originally.
