Jumbo frames, change the MTU size without VM guest tension

I'm trying to disable jumbo frames, specifically to change the size of the mtu to 1500 (instead of 9000) in vcenter on some hosts. Some hosts run esxi 4.1, others are running esxi 5.0. I wonder if it is absolutely necessary to turn off the virtual machines that are connected to the iscsi san network while making this change, or is it relatively safe to make this change, while VMS are running.

Each VM has active multipathing, 2 vswitches with 1 NIC associated with each.

I know how to make the changes, regarding my questions whether it is possible to safely make changes while VMS still access the SAN.

Yes, it is something that I do in my lab quite frequently without using maintenance mode. Memaad notes, maintenance mode is always preferable to avoid unnecessary risks, but it's finally to you.

See you soon.

  • Change the MTU size to vmkernels on dvSwitch

    Hi all

    I have about 40 ESX hosts that belong to dvswitches different 6 and 6 different groups. Each host has 6 vmknics created for the dvswitch and all have value mtu of 1500. Can someone help me with a cli script to change all vmks 9000 MTU?

    Please let me know if additional information is required

    Thanks in advance.

    Try it like this.

    $MtuSize = 9000
    foreach($dvSw in (Get-VirtualSwitch -Distributed -Datacenter MyDC)){
      $dvSw.ExtensionData.Config.Host | %{
        $esx = Get-View $_.Config.Host    foreach($pnic in $_.Config.Backing.PnicSpec){
          $netSys = Get-View $esx.configManager.networkSystem      foreach($vnic in $netSys.NetworkConfig.Vnic | where {$_.Spec.DistributedVirtualPort}){
            $spec = [VMware.Vim.HostVirtualNicSpec]$vnic.spec        $spec.mtu = $MTUSize        $netSys.UpdateVirtualNic($vnic.Device,$spec)
          }
        }
      }
    }
    

    It will update the MTU value of each vnic connected to a dvSwitch

  • increase the font size without affecting the spacing

    Hi, when I change the font size, why does affect the vertical spacing of lines of text in a textbox? the principal is the same, but when I change a single line to police 13, with the rest at 10, it bumps a line downwards out of the text box and the rest of the text is not aligned with the opposite page. Is it possible to increase the size of the font of a line without affecting the spacing? Basically I want the lines and space out them to be the same for each page, I'm not sure I know the proper way to do it. Currently, I attack at 13.6 and spacing of the paragraphs to 13.6

    In this case, you can change the Options of object Style for the basic text frame - basic front-line Options. Change it through instead of ascension.

    Window > object Styles

    Double-click on the [basic text frame]

    The first line will then honor your fixed attack.

    Edit: If your policy is increased sufficiently, so the characters can extend beyond the top of the text block. You should be fine with 13 points, however.

    • You may have difficulty the view before printing - check with other users of Chrome to check
    • You can change the font size used by Chrome, permanently if the problem is constant:
    • Customization bars > settings > advanced > Web content > font size

  • How can I change the font size when printing myprograms? Printing is so small that it is barely readable.

    Look at one is easy, printing is not. Never had this problem with XP. Can't find anything in place to change the font size for printed documents. My e-mail address must also be changed on my Microsoft account. Where do you do that?

    Just solved my email impression of non-selection "Shrink to fit" and using the icon to print which is on the email, not the "gear" in the top right of the page parameter page.  Now I can read without a magnifying glass.

  • Can I change the font size for the mail application?

    For the purposes of mail, I want to change the font size.  In other words, the size of everything on the screen when I'm watching and reading mail (do not as much care of the font size in the mail I made up).  Hereby, I refer to the list of the mails which is located on the left of the screen, where it lists who it is from and the subject and the right of the screen, where the content of the selected mail mail message appears as follows.  In fact, it might just be a type of "zoom" as well, not necessarily affecting the size of font in itself.  Want just everything what I see on the screen, reading, to be bigger. Have looked under 'settings' and 'help' and can't find anything about it in two places.

    My mother is 90 and said: "it's so small, I can hardly read it.  Wow, thought new Windows 8 was supposed to be a new world, easy and user friendly; and yet, here, I am an "expert" was using the PC since the beginning of the Radio Shack, start Windows, etc... but have to post this question here.

    Thanks if you can help with that!

    Some of them depends on the capabilities of your display.  If she has enough pixels to do without causing interference, you can adjust the DPI (dots per inch) of scale and it will expand the size of the text and the items for you.

    To see if you can do it, go to your charm to search and type 'scale '.  Choose the search result it shows and then try the configuration in larger size.

  • I can't go in the settings of fonts. How to change the font size?

    I had downloaded the latest version of Firefox and I finished it sync for my Android phone. I went into a kind of dialog box settings and accidentally changed my fonts and text settings and now I can't read any of my Gmail which is in my account on my desktop - it's too small. I'm trying to figure out how I can enter in the content settings (I feel that I do once I have enter the menu 'options' on the content settings page, but I don't know how to bring up the menu of the content/page settings). I use my desktop PC for work and I can't use it with the font settings and how they are now. I also read where the issues are taken, but no one knows how to find the answers to the questions people are asking. How do we get the answers that people give us on the issue, we asked?

    I hope you can help me as soon as POSSIBLE, I can change what I as soon as POSSIBLE. I'm working on my pc 24/7 for the work and is not helping me when I can't read the emails and I can't solve the problem.

    Thank you!

    Hi Upset2,

    Sorry to hear that you are having problems with font sizes in Firefox on your desktop.

    Text sizes really small for each Web site you visit, or is it just your emails?
    Text sizes are really small on your desktop and Android or only one?

    There are several things that could cause your text sizes to seem strange, so I'll take you by a couple.

    First of all, your email page could have a zoom. On your PC, could you please try open Gmail and then by clicking on the icon at the top right of your screen that looks like three lines?

    This will bring up a new menu and near the top of the menu are three buttons: a minus (-), a percentage (that is to say, he could say 70%) and a plus (+). Please click button percentage - this should Gmail zoom to 100%.

    If that doesn't fix it, let's try using the method on your printout. To access the content settings screen, click the button in the top right that looks like three lines. Click on Preferences. A new window will open. Click on the 'Content' button and follow the instructions that you change the font size.

    There is another version of the instructions I just gave you, with screenshots, here: font size and zoom - increase the size of web pages

    Mozilla Support issues are all handled by volunteers, and at peak hours, there may be a delay. Thanks for your patience!

    I hope this helps.

    Due to problems described here https://support.mozilla.org/en-US/questions/1012057?esab=a & s = & r = 0 & as = s I erase that I need something (an extension, perhaps) I want to recognize and change the font size and "BOLD" fonts in each page.
    Is there something like this?
    Maybe also for the bookmarks bar...

    You can use the NoSquint extension to define the size of the font (zoom text/page) and the color of the text on web pages.

    possible to change the font size of the bookmark toolsbar?
    upgrade to firefox v22 and notice this bookmark toolsbar got bigger, some bookmark font cannot be displayed, it is normal? possible to change?

    Hello

    Firefox on Windows is now after display, scaling options that can make the biggest text on screens at high resolution.
    You can adjust the resolution of your screen.
    To change it follow these steps:

    • Type of topic: config in the Firefox address bar and hit the Enter key.
    • If the warning that this might void your warranty , click I'll be careful, I promised.
    • Search for layout.css.devPixelsPerPx

    • Double-click layout.css.devPixelsPerPx to edit its value. The default value is - 1.0 in Firefox 22 and above. Change it to 1.0 to run as in previous versions of Firefox.

    If necessary, further adjust the value of 0.1 or 0.05. Values between 1.0 and around 0.5 to reduce the size of the elements. Use a value greater than 1.0 to increase the size. For example, a value of 1.25 will increase the font size of the 125% to account for the default DPI setting in Windows 8. Check the value that you enter. Definition of a value that is too small will take everything away and too high will explode things.

    If the web pages should always be adjusted so you can watch the extension Default FullZoom Level or NoSquint .

    To adjust the font size for the user interface, you can use the extension of theme font & size changer .

    This solve your problems? Please report to us!

    Thank you.

  • How to change the font size and color in the toolbar Firefox 10?

    I was switched to Mozilla Firefox 10.0 by a representative of Dell. I had been using IE8. I have the Windows 7-64 bit operating system. I can't read my toolbar on Mozilla it is so small and the police is black with gray background! Is this not a great combination. Is anyway to change the font size of toolbar and from the colour? I downloaded the module Amazon on WOW! It's clear as a Bell, but Mozilla is absolutely horrible. If I can't get the editing toolbar I need to know another browser to use cause after only 5 hours trying to customize and use Firefox 10.0 I'm all done. I can't get any telephone communication or chatline support. I was in the knowledge base up until I can recite! And Kaspersky is not compatible. More of a nightmare what I need.
