Hi Tom,
Here a command for you to attach the sharable/none-sharable disks manually,
Usage: xm block-attach <Domain> <BackDev> <FrontDev> <Mode> [BackDomain]
It can be issued under Dom0 to attach your newly created sharable disk manually without a reboot.
e.g.xm block-attach 9 file:/OVS/running_pool/52_pvm_el5u1_x86_64/sharabledisk_again.img xvdb w! 0
Note that 9 is your DomU id,and 0 is Dom0 ID.
The command would not take effect any more after reboot,so for the permanent use,please write that info into vm.cfg as well.
Hope that helps for you,:)

  • Add shared disks without shutdown vm

    Hi all,
    we have a Pc with VMWare 2 and two VMS with
    Oracle 10g on RAC and CentOS 4.7 . There are two nodes (or vms): rac1 and rac2.
    Each VM has shared SCSI disks.
    Is there any way to add shared disks without shutdown the VMs?
    thank you.

    Well,
    Look the link:
    http://www.vmware.com/support/ws5/doc/ws_disk_add_virtual.html
    You must shutdown the instance.
    but in your case, I dont know, maybe shutdown one VM, add the disk, and restart.
    So, shutdown other vm, add the same disk, and restart. After, you can add the disk to disk group
    if you are using ASM.
    Please, correct me if I'm wrong.
    Cheers

  • Photoshop elements quit working, I uninstalled it, tried to re-install using the cd, but getting errorPhotoshop elements quit working, I uninstalled it, tried to re-install using the cd, but getting error, any other way to re-install it without the disk ?

    Photoshop elements quit working, I uninstalled it, tried to re-install using the cd, but getting error, any other way to re-install it without the disk ?

    Yes.
    Download Photoshop Elements products | 13, 12, 11, 10
    However, the real issue is why the program is not working. Did you install anything recently?
    When you tried to re-install from the disk, did you shut off the antivirus program temporarily?
    Have you tried a system restore to a point in time when the program was working properly?

  • Way to see infotype screen without going PA20?

    Hi Experts,
    Is there a way to see just the infotype screen without going to PA20. I want to see the changes I am making using T588M and see which field has what technical field name and how the screen will look like when I make changes using T588m?
    Thanks a bunch,
    JESS..

    Hi,
    You can also check screen painter through transaction SE51. Give the module pool name under u201Cprogramu201D and the screen number, select layout editor and display. If you click on any field, the technical name will appear in the u201Cnameu201D row above. Further, any field with u201C?u201D is a mandatory field.
    Hope this helps.

  • Can't lower voice memo volume. My decrease button doesn't work anymore. Any other way i can lower it without disabling speaker

    Own an iphone 5. Can't control voice memo volume from anywhere that deals with volume on my phone. My decrease button doesn't work. I have to listen to my voice memos on full blown volume. Can't lower it from settings or from music. Help please!

    Hi,
    thanks for your answer. 
    The Size of all disks is: 6 x 4 TB.
    In the Pool are 5 x 4 TB plus 1 x Hot Spare. 
    It comes up to about 14,6 TB of Data formatable.
    But tried it also with just 3 x 4 TB to see if it works. 
    I just made a Raid5EE on the controller and then used Storage Spaces with simple, all worked fine. 
    Here the results of my tests: 
    1) your command had to be modified (typoe in usemaximumsize, and had to add -ResiliencySettingName Parity. 
    new-virtualdisk -friendlyname testpsh -storagepoolfriendlyname test -ResiliencySettingName Parity -usemaximumsize
    But anyway, my problem is not creating the virtual disk, but formatting the partition if it's parity only. 
    I added a screenshot: 
    Here you see my storage pool, and I added 3 virtual disk. 
    1 simple, 1 mirror, 1 parity. Only the parity cannot be formatted. The others can. No mather which size I do. 
    About a testserver, I added 4 x 4 TB to a VM (VHDX-files) and could do parity without problems. So it seems it is this server specific.
    As it worked with another controller, I really wonder if the controller could break parity of Storage Pools?
    The other weird part is, it sais "Raid" as BUS, but it's set to pass through, in details I see the serial of the attached HDD. 
    This is what properties shows on this volume. Always RAW. 
    I also tried Software Raid5 within the server. 
    This also worked fine. So really only parity. 
    Thanks

  • How Can I change my country location  without using my creditcard? I Cant Use my creditcard but I need it to change my country location, Is there any other way?

    I Moved to Venezuela From Canada 4 Month ago.      I had some apps on my iphone that I had to pay with my creditcard to download, I used to have the App: Wahtsapp it cost 0.99$ I bought it when I was i Canada and I coould use my creditcard, But I deleted "Whatsapp" but I was not a proble, because  I had a security copy on my computer, But I needed to Update the apps and I couldnot do it, because I had to put my payment imformation, But I actually i have some troubles with my creditcard, so i cant use it.
    is there any other way to change my country without putting my payment information, that way I can update my apps without having to put my payment information.

    You must have a valid form of payment for the app store in the country you are using. Most app stores are separate legal entities to comply with local laws. It is possible to have an account without a credit card, however; see: http://support.apple.com/kb/HT2534

  • How to see Shared Members in Smart View on Ad-hoc Analysis mode

    Hi All,
    We are using Hyperion Planning v 11.1.1.3.
    For the alternate hierarchy we have created shared members. But in Smart View we are unable to see Shared members hierarchy in Ad-hoc analysis mode.
    Is this limitation in Hyperion Planning?
    Or
    Is there any way to see shared members Hierarchy in Smart View in Ad-hoc analysis mode?
    It is urgent requirement Please let me know as early as possible
    Thanks in Advance!!!

    When you say open data form in Ad-hoc mode, can you do that? I think when you select Ad-hoc mode, you are basically connecting to Essbase and therefore need to manually select the members. (of course, I've got a 11.1.2 env right now so not too sure of 11.1.1.3)
    I'm able to just go to Member Selection and select whatever hierarchy i want, Shared or Stored, when I'm connected to Essbase. When connecting to Planning, I dont have any option of opening the form as Ad-hoc mode.
    Can you see the hierarchy if selecting the members using Essbase connection and not planning?
    Cheers,
    Abhishek

  • A way to SEE changes in audio data as you compress?

    I know I should be mixing with my ears and not eyes but this is a bad habit I picked up from my cool edit days and it just refuses to go away. Im trying to audition different compressor settings on already-recorded audio by actually SEEING the changes to the audio file as I make them as opposed to just hearing them. I have my compressor on the channel strip. For me to see these changes on the audio file, do I have to bounce the file every time I make a change to the settings or is there a way of seeing these changes without that hustle?
    Thanks.

    Haven't really messed with Soundtrack Pro but I will explore that option. Thank you.

  • Seeing shared iPhoto libraries in Aperture

    I have Aperture on my iMac and iPhoto on my Mac mini. The iMac and Mac mini are networked. The iPhoto library on the Mac mini is set as shared in the preferences. If I open iPhoto on my iMac I can see the iPhoto library from the Mac mini. If I open Aperture on my iMac I can not see the shared iPhoto library from the Mac mini. I am using the 'Show iPhoto Browser' option in the File menu. I can see my iPhoto library on my iMac in the iPhoto Browser.
    In Aperture is there a way to see shared iPhoto libraries from other local networked computers?

    I don't think that part of Aperture is that advanced. I'm pretty sure it only looks on the local Hard Disc.

  • How can I see the disk in airport extreme

    Hello
    I have an airport extreme, I downloaded the Airport Utility, I connected the printer and everyting is fine, I can access the printer from other computers at home. Then I unplugged the printer and connected an USB disk (working of course), and everything is fine, Airport Utility detected it. However, I dont know how can I access the disk from the computers. I have all windows 7 computers at home, but now way to see the disk. What I am doing wrong
    thank your

    I don't use this setting, so can't offer much assistance, but do know that your computer is exposed to the Internet, so it will receive all inbound traffic.
    Normally, a typical use of Default Host would be to setup a game console to allow online gaming when NAT settings otherwise would not allow communications to occur.

  • Repair Disk without CD (Snow Leopard)?

    Hi everyone!
    My good ol' macbook has been running a bit slow lately so I went to Disk Utility and selected to verify the disk.  I was then informed that it was corrupt and I need to repair the disk, but I need my OSX installation to do it since I've been traveling and no longer have access.
    So, I have several questions:
    1.  Is there a way to repair the disk without the CD or do I just need to go buy another one?
    2.  How do I actually go about repairing the disk when I get the CD (if I absolutely need one)?
    3.  Do I need to be sure that I have everything backed up on my external harddrive before I do this?  I have time machine going frequently already, but I just want to be sure if the time machine back up is enough or if I have to do a manual copy & paste backup.
    Also, I'm running OSX 10.6.8 (Snow Leopard).  My macbook is a 2007 model (still kicking! Just when I think of getting another one she proves me wrong) and I don't think I can go up to Lion... or at least not Mountain Lion for sure.
    Thanks!

    1. Yes, there is. Restart the computer with the Shift key held down to quietly run a disk repair utility.
    2. Restart from the CD and open the Disk Utility from the Utilities menu.
    3. Create a bootable clone on a second external drive. The Time Machine backup won't itself help if the internal drive gets erased and there isn't a second bootable system available.

  • Can I repair my startup disk without installation disk?

    Disk utility is showing me the following after I ran "verify disk":
    The volume Mac HD was found corrupt and needs to be repaired.
    Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
    I don't have the installation disk.  Is there a way to repair the disk without the installation disk?  I'm running mac os X 10.6.4.
    Also, I'm very new to mac OS so please keep any answers/help simple for me.  Thanks.

    If you have a TM backup on an external drive, restart the computer and hold down the option key. You will get a selection of drives. The TM drive has a recovery drive also. I think it will be listed as Mac OSX. Select it and try booting from it. Your internal drive might be bad and not allowing you to start from that recovery drive.

  • Is it possible to use iPod as external disk without installing iTunes?

    I was wondering this because I would like to be able to use my iPod as an external hard drive at school. I cant install iTunes on their computers without administrator rights. I just want to know if I can connect it without having to go through iTunes to saftly disconnect.

    Assuming you can use the iPod with iTunes at home, connect it to iTunes and change the setting to manual transfer. This automatically enables disk use.
    Your iPod should then show up on any other computer as a hard disk without the need to install iTunes.
    You can eject the iPod after use with the “safely remove hardware” icon in the system tray next to the clock (looks like a grey rectangle with a green arrow above it). Click on this then select your iPod. Or through Windows, select start/my computer, right click on the iPod, select eject.

    IOS: using facetime http://support.apple.com/kb/ht4319
    using an ipad will use the email address since you can't make a phone call.  see the link.
