Maintenance mode enough to stop SAN and networking?

Community of VMWare,

We will present some maintenance on your LAN and SAN network that connects our system of blade HP C-7000 with about 14 5.0 ESXi hosts and 3 HP Lefthand P4000 Series clusters (6 knots), 3 groups of VM. Thus, the chassis of C-7000 whole as well as the SAN will lose network connectivity. We do not have a second VM or SAN environment to migrate customers to.

Our plan is to:

1. stop all the VM to its customers.

2. place all hosts in maintenance mode.

3 temporarily disable HA and DRS to prevent vMotion when the host is brought back to the top of the maintenance mode.

4 judgment of the SAN.

5 stop/Perform maintenance on the network LAN/SAN switches.

6. turn on the network switches.

7 turn on the SAN.

8 disable the maintenance for the VM guest mode.

9. turn computer virtual guests.

10. turn on HA and DRS.

This sounds like a good plan? Do you see anything wrong with it? I'm curious to know if maintenance on hosts mode will be sufficient to avoid problems and whether the SAN data store and the road reconnects. I'm afraid that if I completely stop the hosts, it will create problems of network such as vmNIC etc renumbering.

Your help and your thoughts would be greatly appreciated.

Yes, when we realize tests of UPS, we take the whole environment down, let the UPS stops completely and all...

In addition, I also stop the hosts interview on the chassis as well...

Have not had any problems... Touch wood

If you do not change anything fundamental about the chassis or guests, you should be ok... And when hosts are down (if) then it won't matter if the uplinks disappeared... If you leave them in maintenance you will obviously see some, if not many, alarms

  • Disable HA or use the Maintenance Mode when the upgrade of the network switches

    Hello

    We expect the upgrade to our network switches. In the case where the hosts loose network connection I want to avoid having HA suddenly and guests try to run current virtual machines. What is best practices for cluster HA-activated in case guests loose network connection?

    Disable HA or put all hosts in maintenance mode? Or is there another suggestion?

    Vickers

    If you are using vSphere 4 there is option to disable HA response to failure without disabling agents HA HA. This option has been added specifically for when you know you're going to do the maintenance of the network and that you do not want HA answer when the management network is down. It is much faster to do that that in order to completely disable the HA or put all hosts in maintenance mode.

  • vCO Bug - Maintenance mode?

    Hello

    I find that the workflow item 'Exit Maintenance Mode' does not work. If I place a host in maintenance mode (clearly working, vsphere client) and then try to run the workflow, he does not see the host as being in maintenance mode.

    I tried to write my own scriptable task:

    var ConnectionState = host.runtime.inMaintenanceMode;
    
    
    System.log(ConnectionState);
    
    
    

    [09:45:14.393 2014-09-02] [I] false

    The result of this is always False.

    Any ideas?

    This may be caused by the use of the service of the inventory. Try to disable it by adding the following line to the file vmo.properties vCO

    com VMware.o11n.vim.useInventoryService = false

  • Evacuation of the virtual machines before maintenance mode

    When ESX is placed in maintenance mode - it should give you a vmotion option functioning of the virtual machines on the other hosts in the same cluster?  Or it only move down vms to other hosts?

    Thank you

    DRS is your friend here, ensuring that VMS are evacuated.

    If you are unable to vMotion VMs manually from the host, the y is unable to escape during operations in Maintenance mode. The host will therefore go not in maintenance mode before having been involved and sort the vMotion.

    Most often, CD-ROM etc are involved here, but validation of vMotion also includes such things as the availability of resources and port groups (that is, if a group of ports corresponding to that used by the virtual machine is not available on another host in the cluster that has the resources available, the vMotion will not pass validfation and the virtual machine will remain on the host of 'Maintenance Mode').

  • maintenance mode > reboot > network works.

    I have used ESXi 5.1.0 (Build 799733) on a Home Desktop/Server for six months, and I have done up and down the system several times. Recently I was going to have a planned interruption and decided to put the system in "maintenance" mode (life the vSphere client) now when I turn on the system it is impossible to access the network no matter what I seem to do. I can ping myself very well. The system to see that there is a network because I can see the status of connected network connection vmnic0. I think the system in maintenance mode and then cut off the power supply did something funky with the network settings. I look at the following articles of the KB, but it worked. Any other ides?

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 9639912

    I'm tempted to reset the configuration of the system, but I hesitated because I don't know what he would do.

    After having replaced the nic with a new edge card, the network is back.

  • LM 4.0, Service VM and ESX Maintenance Mode

    I'm trying to put one of my hosts LM 4.0 in maintenance mode, it hangs there because of the virtual of Service machine.  Y at - there a trick to getting the crowd to enter maintenance mode without trying to stop the virtual machine in the console?

    This is the correct behavior even though I agree that it's awkward. You can disable the host extending on that host and the VM service will get cancelled. Then, re-enable host extending on when you are finished with the maintenance mode.

    To disable the host covering, access resources, hosts, then go to the properties of host page and uncheck the "Enable host host Spanning.

  • Wi - Fi and network suddenly stopped... Local only (Vista).

    I basically solved my problem. I'm writing this in case someone else has this problem.  (I was without any networking capability for about a month after a failure and request Windows update several uninstals due to a malfunction stopped responding - don't know if any of these are related?)  The computer couldn't even * is * on the network.

    First, I eliminated material as being the cause.  My suspicion is that a firewall was still in force, even if I completely uninstalled my Antivirus and disabled the Windows Firewall already.  Then I tried to disable the Base filtering engine (the "Services"), and * voila! * all returned.  I immediately installed a temporary, caught up firewall on Windows Update and reinstalled my Antivirus.  Everything's fine now, as long as I keep the Base filtering engine.  Rebooting it stops all the networks again.  I don't know if there are risks to let off, but for now, I'm happy.

    ******************************************************************

    Sorry if it's verbose.  I was no longer able to use networks of any type for about 3 weeks on my laptop Vista Home Basic.  Are wired and wireless down (I use different routers to a cable and Wi - Fi), while my Office XP continues work as a champion using a router.

    Everything had been working fine for a year or more until what all of a sudden stop.

    I also can't connect to the network wirelessly at my school more (it is a laptop).

    (Note that I am not currently under any additional firewall beyond the Windows Firewall).

    Three concurrent problems occurred at the time of the failure which could be related.

    (1) I tried an uninstall of the interface software LegoMindstorms NXT after a school project.  Uninstalling shifted on for about an hour and has stopped responding.  I did a system restore and repeated the uninstall.

    (2) I noticed the 'auto-protect active"icon of Symantec AV was changed to"disabled", even if I was not disabled it and my license is up to date.  In the settings menu, I unchecked and recontroler the auto-protect of selection, but it didn't fix it.  I tried to uninstall it, and it stopped responding as well.  I did a restore and another attempt to uninstall succeeded.  Windows Firewall and defender will have to do for now.  (I'll be reinstalling my AV soon and will get updates when I am able to connect again).

    (3) I reviewed my recent Windows updates installed and found the last (KB982536) has a status marked "failed".  I uninstalled that before that failed just to see if she had caused the next update not working, but it does not solve the problem.

    * I tried several system restores, but none have set.

    I also did the following:

    tried another ethernet cable
    * removed wired and wireless cards from the Device Manager, rebooted and (allowed them to reinstall)
    * updated to the latest version of the NETWORK adapter driver by using my other computer (XP) and the copy of the USB
    * sfc/scannow
    * checking memory
    * chkdsk

    (An upgrade to Windows 7 can solve the problem, but this isn't an option I will consider for now.)

    Your settings do not look correct to me.  There is no default gateway (which alone explains why you can't connect).  Good number of other entries look right either (they are different, that I'm used to seeing).

    I suggest you remove all your network connections (remove them all) and start from scratch.  Configuration of the LAN connection, and when you get this work then set up the internet connection and get this to work.  Do not re - install connections, you do not need more (it seems that you have a good number of people).  You have tried to repair these connections and there may be something wrong with them which cannot be repaired (they can be corrupted or some type of conflict or other).  Starting with a network connection fees registration with nothing (not wired or wireless) and do everything as if it was a new machine can solve the problem.  Make sure you know the correct settings before deleting the current connections (and make sure that they are correct even if you need to contact your ISP for confirmation).

    I hope this helps.

    Good luck!

    Hey guys I have a problem that is really starting to stop a little worth. I recently bought this desktop computer and I had problems with the GPU drivers when I play some games. In the middle of my game, I am reduced to a minimum and maximized every 15 seconds and have the error "display driver stopped responding and recovered, NVIDIA Windows Kernel Mode Driver display driver." I tried SEVERAL solutions from different threads, and I still have this problem.

    Things I've tried:
    -Added a TdrDelay (8) in my regedit
    -Defining my CPU PhysX on my GPU instead of automatic selection
    -Install an older driver over the last.

    Hi Vexin,

    Try the following steps to solve the problem.

    Step 1:

    I suggest you uninstall the device of the graphics card from the Device Manager.

    To open the device in Windows 7 Manager - check this link.

    Once uninstall you the graphics drivers in the Device Manager restart the computer.

    Step 2:

    Visit the manufacturer's website and download the latest drivers for the graphics card.

    Link to the manufacturer's Web site.

    I don't know what you have installed, but HP lists only single display drivers 8.15.11.8644A out on 09/01/2009

    It seems that you install either Nvidia graphics, and if you had looked at the Release notes you would see it is a driver for reference only and may differ the driver provided by the manufacturer of your laptop.

    So I guess you can install other drivers via update of windows, which is a no no.

    Hiya,

    I have recently installed Windows 8 Pro, installed all of my usual applications etc..
    The problem I've encountered is maintaining display driver crashing. Or have waiting periods. The exact error message reads;
    "Display driver NVIDIA Windows Kernel Mode Driver Version 306.97 has stopped working and recovered."
    Until now it expires randomly even when the computer is idle, and more frequently when I watch videos online. Also, watch a clip full screen on some sites like YouTube is ok, but on others, it is very laggy (updated maybe once per second the image) and the sound is out of sync.
    I can't find a way to properly uninstall the graphics driver.

    At least yours is working semi... I have the GTS 450 (uses the same drivers) and the mine does not at all... Stuck with the regular game pilot integrated ATM and can not all games... Microsoft told me to wait a few weeks and for the reminder and Nvida said 10 ways to uninstall and reinstall the drivers for same. Hope someone with to get a fix for this soon.

    Hi guys,.
    Looks like this isn't just me.
    Just an update, that I can not confirm it as a solution, but I have not encountered any problem (a little screenlag aside) since the installation of the drivers beta. For me, the beta version of the driver is 310.33, R130. The only other change to my system updates Adobe Flash version packaged with Google Chrome to 11.4.31X to 11.4.402 to eliminate serious problems when you watch the video in full screen.

    New edition;

    If you still receive the error message, try the following steps;
    Has. try to perform a clean installation of the driver.
    Download the latest drivers for your graphics card. Run the downloaded file, and select "Custom Installation". In the next screen, you will see a checkbox or similar labeled "Clean Install".
         

    You can do so by visiting nVidia Driver Downloads (www.nvidia.com/Drivers). Automatically detect the right driver or download using the form. The best way in my opinion is to use the GeForce experience, who will do anything for you in two clicks and a reboot.
    B. close all other programs
    It is possible that the error was caused by too many programs that need to use the resources provided by the graphics card/chip. It is also possible that a certain program caused a conflict that pilots crashed.
    You can try closing some currently open programs one by one and see if the error persists, or restart your system with disabled startup programs and allow them one by one to find the culprit. If the error is too persistent to do the above, it would be easier to start in safe mode option.
