What happens if my VC is down, would the HADRS still work?

Hi all

I'm new to Vspehre4.1, I was wondering if I could find documentation on best practices on the same.

I have welcomed Vsphere 4.1 on a physical server and that you have configured HADRS on a few of my ESX hosts. If my VC falls down (the physical server) would be the AP still work? and if 'YES' then how?

Please suggest, thank you!

Hi Vgeek1,

Welcome to the forums.

HA comes from the agents installed on the ESXs, so they can check that all members of a cluster are available permanently. The initial configuration is performed by the vCenter server. But once the cluster is in place, it continues to operate even if the vCenter crashes. Ditto for the VMs. Read vSphere availability Guide for more details.

DRS is based on statistical calculations made by the vCenter to check the balance of clusters. In case the load is not evenly distributed on the servers, it will move VMs to balance the load. When vCenter is stopped, of course this feature does not work. But it is not mandatory for your virtual machines continue to work properly. Guide to management resources reading for details.

It will be useful.

Concerning

Franck

    Of course, you can reinstall Windows. It's a shame, if that's the only way to solve this problem. :-(

    Because you will lose the lot, you will need to restore from your external backup. If you do not back up your files regularly then it is a good time to review your backup strategy.

    You can always back up your files to boot the machine with a Ubuntu boot CD. Unfortunately, it is much more difficult than restoring from a backup disk.

  • What happens when managed, segment size of memory the server has

    Hi all

    Can anyone provide some information on what happens after reaching the size of memory managed server segment by... We are on 11.1.2.3. Our is a compact deployment with EAS, APS, RA, WA, web applications deployed on the single managed server work space. Our chunk size is set to 8 000 MB (8 GB) and I'm trying to understand what happens once the limit is reached, I tried searching for an answer in the forums of Weblogic, but did not find anything. So maybe if someone could shed some light on what would help a lot.

    Thank you
    Ted.

    I expect the Dungeon of increasing size until the segment maximum + fresh General, the gc must retrieve the memory to be allocated again and is not released to the OS.

    I value and often use the button SHOW DESKTOP which has always been in my QUICK START MENU... until I recently upgraded to the latest version of Firefox because he promised to be faster (and my experience online in spite of paying for "high speed" is anything but fast!). I see that the icon was not just moved but DELETED and I'm not at all happy about it. What happened and how I get it back? Thank you.

  • What happened to 'bookmark this page' selection in the menu "Show bookmarks" on the right?

    Now, I have to:
    1) click the Blue Star stupid to get the menu to place my new bookmark where I choose to do instead of going to unsorted bookmarks again...
    OR
    (2) raise or having the menu bar and click on the menu choice "Bookmarks" to "bookmark this page", which shows what I would call the menu choice or sorting which allows me to access my bookmarks menu...

    .. where I wanted to go to a bookmark, AND I get to select 'choose', which is what I used to do when you add a bookmark.

    I want the selection 'bookmark this page' return on the "Show bookmarks" list on the right... where it belongs. Why everyone wants to keep hide useful tools?

    29 Firefox STINKS and I got in trouble from the beginning... and since the mistake of reset.
    I now have a record of things that I have no idea what to do what while resetting, I got "Oooops it's embarrassing, we have a problem" or something. Clues about what to do with all these 'junk' (now to me) might also be useful.

  • What happens to iCloud library after you restore the old library on Mac?

    I have known problems with iDevices displaying thousands of 'new' images, even if they are all already in the library of Photos on Mac and on iCloud photo library, I posted on here also.

    Through the various attempts to stop these 'new' photos to reappear again and again, I found myself with several copies of the thousands of images in the pictures on Mac and therefore in iCloud (i.e. they synchronized). Rather than go to the library and find it manually and remove these duplicates, I would just return the photo via Time Machine library to its prior state of duplicates. After I restored the local library there will be no duplicates and have much less images than what is in the iCloud, photo library.

    My question:

    'Local library restored' rule and the iCloud library will correspond to the now smaller local library? Or all of the duplicate to my local library files will be synchronized? Put an another passerby, did restore Time Machine also "informed" (impact) the library to match the local library restored iCloud?

    Restores the local library AND remove all images in iCloud and then re-upload a 20 K library to iCloud the only way?

    Thanks in advance.

    First, you will need to erase your iCloud library in iCloud, I'm afraid, Pope, prior to activating the library restored as a your photo library system.

    I only tested once. After the restoration of the library of Time Machine, the library was no longer recognized as the photo library of the system, even in the same location on disk. That caused the iCloud photo library to deal with the library as an additional library must be downloaded to iCloud. The library was merged to the existing library, so older duplicates have been removed.

  • What happens when you specify multiple iterations of the parallel loop that you have processors?

    I have an app that does the same things together up to 10 times for different material resources. For example, I have a list of 10 COM ports I want to send orders series. I want that they be executed as close to synchronous as possible, but up to 200 ms sync would be acceptable. Currently, I use a loop set up to 10 parallel iterations and assume that LabVIEW will juggle processors according to the needs, the iterations run it as simultaneously as possible. Experimentally, LabVIEW indeed seems to create 10 parallel loops, even when running on a computer with only 4 logical processors, otherwise you go 10-element inside the loop would only be not able to complete, right?

    My question is, I'm doing something verboten with my number of iterations of the loop? According to the help of LabVIEW for loop iteration parallelism dialog box: "If you plan to distribute the VI on multiple computers, set number of instances of parallel loop generated equal to the maximum number of logical processors, you wait for one of these computers contain never.» Clearly I'm violating this opinion and yet it seems to work. My performance will essentially be the same as if I had 10 blocks of code in parallel on the block diagram?

    "Reading'how many Threads don't LabVIEW allocates?" links to this page, it seems that, at worst, LabVIEW is hungry for thread and switching of threads between iterations, but my short demand slowing down enough to accommodate this suboptimal situation. At best, LabVIEW has allocated 4 threads per the enforcement system, so as long as I have at least 3 processors, there are at least more son than the parallelized loop iterations. It's all a bit confusing.

    In this case (where you're interacting with the external hardware and have an appointment) there will be a delay of inheirant at each iteration.  THUS, "Oversubscibing" or by allowing the parallel proceedings as logical processors, actually improves performance by running another period of waiting during the iteration.  In fact, you're not "Violate the advice" of oversubscibing.  You use this technique correctly!

  • Windows 2008 - what happens if it does not activate in the grace period?

    Hello

    I know it is a forum for Vista but everything on the web seems to tell me that way...

    In our Organization, we plan on using KMS for activation of our Windows 2008 servers (we have only 2 of them at the moment). However what I read you need at least 5 physical servers Windows 2008 (not the Virtual Machines) before they will start to activate.

    My question is: what will happen to the Windows 2008 servers if they do not activate the grace period?

    From what I can tell they should keep normal operation (reduced functionality Mode has apparently been removed from Windows 2008) but will be many notifications to activate me now whenever you log on to the server.

    Thanks for your help.

  • What happens when I run recovery disks in the computer?

    Original title: .vista

    I want to run my vista recovery disk, what actually happens when I do this.

    Hello

    When you run the manufacturer's recovery disk, it puts your computer / computer laptop back to factory settings. the new condition that you bought it in.

    All your data: pictures, music files, etc. must be backed up on an external hard drive before making a recovery, because they will be normally lost.

    All data updates to Windows, 3rd party programs, and that you have installed since your purchase of computer no longer the disk hard as the hard disk is normally wiped clean of everything during the recovery process.

    The above is called a destructive recovery.

    Some computer manufacturers also have the possibility of a non-destructive recovery, which stores programs and data in place.

    But, the data must be saved IN the MATTER.

    If your problem is so bad that you need to reinstall, a non-destructive recovery does not solve the problem of normally and most destructive recovery needs to be done

  • What happens if I disable Internet Explorer or the XPS Viewer? (Windows 7)

    Greetings,

    Whenever I do a reformat, when I get to the step of optimization, I'm very tempted to turn off Internet Explorer and XPS Viewer (in the Turn Windows features On or Off section of the program manager).  However, they both say a warning that they are used with other parts of Windows.

    Has anyone experienced with this?  What would he do?

    Hello

    Thanks for posting your query on the Microsoft Community.

    According to the description, you want to disable Internet Explorer and XPS viewer on your system and when you try to do, you get a message indicating that they can be used by other applications on windows.

    That statement is correct, because they could be used by other applications. For example, if you try to open a link by using any third party browser, this link would automatically open in the default browser and if you default browser is Internet Explorer, you must have Internet Explorer installed on your system. and same thing with the XPS Viewer while opening the XPS document.

    However, you can disable these two from your computer by changing the default programs associated with them.

    Hope the helps of information. Let us know if you need help with Windows related issues. We will be happy to help you.
