VCA Mode change

Hello
I'm downgrading to Westmere EVC mode to conform to the old generation of host we add to the cluster.

To do this, I currently have two clusters created, in production and two hosts using sandybridge.

the second group has a central server inside and westmere generation.

I am aware of the procedure found here:VMware KB: VCA allowing on a cluster when vCenter Server is running in a virtual machine

My question is, rather than quick vMotioning of all hosts another machines.  is it possible to close all virtual machines on a host, set mode now, disconnect the host, move it to the cluster Westmere allow it and then put on all virtual machines?

I know that I'll still have to disconnect and reconnect my vcenter server, but I would like to avoid having a large amount of machines to vmotion if I can find some downtime to stop all.  and make them move with the host.

This idea is possible?

So if I understand what you really want is the future VMs with the host computer, then when you add the host to the new cluster and power them they will run under the new EVC Mode but you essentially in bulk installs what you wanted?

If so, I did what you describe a bunch of times before (especially during migration between vCenters and want to go to the host and all virtual machines), what I would recommend however keeps the VMs powered on. Disconnect the host and then remove the vcenter. Once removed from the cluster and vCenter connect through thick client and put all virtual machines. Then add it to vCenter, in the cluster you want to and feed the VMS and you would be actually resigned these VMs in bulk.

Conversely, you can turn off the virtual machines and keep track of those you want to migrate, put the host in maintenance mode and move it to the cluster that you want and then get out of maintenance mode, cold migrates virtual machines and then turn on. I think that this option will be a little easier.

However, to disconnect a host and removing vcenter will make virtual machines with it, that looks like what you want to do...

  • a speed of read/write DAQ card mode change will reach 200K

    HEY, man,

    I have a project needs to test two points I name them point A and point B, the first time, I should point A 5V DC input, voltage inductive test point B, sencodly, give point B 5V DC input and inductive point test output voltage, this means and two analog ports must read and write sharing mode , and the test speed must be 100 KB, if I have a 200 KB data acquisition card, can the speed of read/write mode change reach 100 KB for an analog port? or, please give your suggest for my this kind of situation, thank you.

    Hi API,.

    I see that you are trying to measure voltages using a single channel at a time on a data acquisition card.

    Unfortunately, you cannot change the inputs to the outputs or vice versa on a map of data acquisition, they are static.

    What I recommend is either using a switch like this: http://sine.ni.com/nips/cds/view/p/lang/en/nid/207130 where you will need a high chassis.

    Or, having four channels, 2 inputs and 2 outputs and try to measure it. You should have the necessary speed as well.

    If you have any other questions, I'd be happy to answer.

    Thank you very much

  • VCA mode

    I try to enable CVS mode on a cluster, but get the message "host is not allowed in the compatibility mode of the current cluster Enhanced vMotion.". Under voltage or suspension of the virtual machines on the host can use CPU features hidden by fashion. ».

    The Group had initially 2 servers Dell PowerEdge R810 with dual cpu Intel Xeon E7540. I am trying to add 2 older servers Dell PowerEdge R900 with quad cpu Intel Xeon E7320. I'm guessing it wont let me enable it because virtual machines under tension using the more recent servers (R810) and their cpu. My guess is correct? I need to power all of my virtual machine to enable CVS or y at - it another way to activate?

    Hello

    Yes your proposal was correct. You can disable all your virtual machines to the VCA mode.

  • Protection Mode change Data Guard.

    Experts,

    Ask your entries on the Data Guard protection mode change, below, is our environment:

    BECAUSE with two nodes: primary
    Single stand-alone Server DB: Eve
    Apply real-time: enabled

    For the primary and Standby databases, it's protection guard data display "Maximum Performance" mode. According to our needs, we would go for "maximum availability". I can go ahead and change, however I have questions in mind before making the change.

    1. do I need to change the protection on both primary & standby mode?
    2. do on DB primary change automatically the standby mode too?
    3. If the answer is NO to the 2nd question, I need to change the mode of protection to standby also? In the otherwise, primary and Standby will be run in two different modes.

    Please let us know of your entries.

    Thank you

    Crazy.

    I'm really happy that it works. Only ORA-16198 has very little information about it.

    And its raining in the North tonight so I have to escape before it turns me on.

    Is equivalent to checking. Hoping no news is good news.

    I've seen this thing before restarting. Last weekend was indeed an Oracle 10 bark at me during the installation of the entire network has been good. Another error, but I finally tried the same thing and it worked also. No complete sense to me, you would think that the listener would govern. And then it takes the real is what's real.

  • VCA mode disabled / vmotion work?

    We have 2 groups of ESXi at our facility for vSphere, vSphere is version build 5.5U1, currently most recent available.

    Group 1 has Intel Xeon E7540 UC.

    Group 2 is brand new and uses recently published processors Intel Xeon E7-4860 v2.

    VCA is currently disabled on the two groups.

    Athe's systems are listed in the VMware compatibility guide for our latest version of vSphere.

    I expect this Setup to be able to live vMotion of virtual machines from the old to the new cluster without the use of CVS on either, but I assumed that the migration back to group 1 would require cluster 2 to affect the level of reference Intel EVC appropriate (Nehalem in this case).

    It turns out that I am able to migrate VM direct in both directions with no apparent problems (so far), with EVC mode disabled on both groups.

    Is an expected behavior or if ESXi/vCenter is somehow misreading? CPU compatibility (perhaps because the E7-4860v2 are a very recent model) or some other issue that could lead to problems with these migrations?

    This is normal unless you have turned to bike the VM on the new hosts.

    If a virtual machine has been powered - on on a former host and is migrated to the new cluster, it does not change the current features of the virtual machine CPU runlevel. He will continue to work with the old CPU features on the new host and is therefore able to migrate the old new host without problems, or additional AIDS such as CVS.

    However, if stop you now migrated virtual machine and power it on again on new hosts, the virtual material will apply the new host CPU capabilities (or the level of EVC of cluster, but you do not apply any) and you will not be able to migrate the computer virtual return to the armies of the former cluster.

  • . EML files saved from Outlook Express in XP Mode change their date later in Windows 7

    I use Outlook Express in XP Mode on Windows 7. Sometimes I "save under" taken from emails Outlook Express Inbox in my data drive D:\, which is accessible from the two XP-Mode (such as % ComputerName % D) and Windows 7 (such as D:\).
    I saved an email as messages in "D % computername%:\folder", say, July 9, 2014.
    Then, 3 weeks later, I browse the D:\folder even under Windows 7 with Windows Explorer in Details view, and to my surprise, the update of this post changed July 29, 2014 at the precise moment that I'm over the file. The Date of creation remains as it was - 9 July 2014.
    Surprises I encounter almost every day, both at home and at work, where I also use Outlook Express to receive emails in XP mode on Windows 7. Simply by looking at a folder that contains recently saved .eml, change files automatically their update at the present moment in time, without even opening an any of them.

    This strange behavior is unique to .eml files. It does not affect any other type of file that I save in XP mode to be seen later in Windows 7.

    Surprises I encounter almost every day... Simply by looking at a folder that contains recently saved .eml, Exchange files automatically their update at the present moment in time

    When you head into a file in the Explorer, Windows will search to see if there is a manager of property for the type of file involved, and if there is, show a ToolTip which gives some of these properties. For an .eml file, it would be ofthe subject , DateReceived.

    These data are extracted the message headers and written to an alternative stream (ADS) in the file Explorer can find them and post them. This would normally happen as soon as the file is written to disk if the location it is written in is indexed, then perhaps the folder that you saved it is not indexed.

    Writing to the ADS is a change in the file, if its DateModified is updated accordingly. The file important dates are not affected - DateSent, DateReceived, DateCreated. Is this a problem?

    This strange behavior is unique to .eml files.

    I don't know if it's true. . EML files are plaintext files, so there is no provision for special properties in the file itself, because it is for, say, .doc or .jpg files. The NTFS file system is a file to has many flows of data, and this is where this type of metadata can be stored. If you want to keep your inviolate .eml files, save them to a FAT drive.

  • Muse of merger Mode change / difference between Muse & Xd

    Hello, I just started to use the Muse, and I have a few questions.

    1. I have difficulties to find a way to change the mode of fusion in Muse. As in Photoshop and Illustrator, I thought that I could set to multiply, overlay, etc., but I couldn't find the opacity setting, but nothing else. I thought that this person below, has the same question, so I followed the answer and bought the Muse Supply widget of Blend Modes, but it doesn't have the setting I was looking for. This widget only allows me to select two or more items and define ways of merging with them. (Like, by selecting an image and color) What I'm trying to do, is simply to change the mode of fusion of a unique shape. For example, I have a rectangular shape and I want it to be "multiply" mode, the background image will appear through it.

    Blend in Muse CC modes

    2. another question, I bought BackBlend as well, because I thought it's the widget to solve my problem, but this one isn't either. But it seems to be an interesting tool, so I am now, but I have no idea how to use. Anyone know how to use it? There is no manual of the user on the site. !

    3. is it possible to open what I did with Muse in Dreamweaver and make changes there? Or y at - it another way, I can make changes to the file Muse with more flexibility?

    4. oh, and what is the difference between Muse and the design of the experiment? I've seen some tutorials for two of them, but have not yet understood the difference.

    Sorry for all the questions, I'm trying to learn them now!

    Thank you in advance for your help!

    1 muse does not support blending modes, because blend modes are not supported by the real browsers

    2.?

    3. you can open the output files of Muse (not the file .muse itself), in Dreamweaver, but this isn't the expected workflow. Changes that you make here are not part of your document of Muse and will be overwritten during the next export.

    4. Design experience is no application to create web sites, it is an application to create interfaces user and application/site plans.
