• Restart VM after you restart the ESX host

  Hi all

  I am using VSphere Enterprise.

  Here my little question, makes VMs always restart after back us running or stopping of the esx host?

  In esx 3.5, when I reboot an esx host, all the virtual machines in this host are still alive (without restarting).

  Pls advice

  Thank you

  The only way, a virtual machine can rest running when it is running on ESX server is restarted is that if FT is activated - in this case, the connections will be seamless switch to the virtual machine "shadow". This is a feature of vSphere, so I don't see how you did not the VMs restart on your ESX 3.5 - even with VMware HA environment, there will be a short break because the VMs will be will be running on the other nodes in the cluster.

• How to add an ESX host licensed to vCenter (vShpere4.1)

  Currently licensed for: 3 guests (Advanced vShpere 4)

  Ok.. so, I have vCenter upwards and in the course of execution, have created my 'cluster' with two hosts. I have an ESX host 3rd I was using mode "assessment" within 60 days.

  This 60-day period was close that expires so I moved and the 3rd license added to this 3rd host.

  I would now like to bring this host to vCenter, for my 'sandbox network' and not actually add it to the 'cluster' so that I can run everything a customer.

  Now, it is said that I am unable to bring this host to vCenter, as it says that I don't have a license.

  So, how can I go on the withdrawal of the license, or get this host (already licensed) in vCenter?

  Or do I have to start from scratch and reload this bare metal esx host to return to Mode Eval?

  Since it's vShpere, there is "No license server" by not telling.

  Licensing vCenter says that 'two' licenses during the third host is the 3rd license already.

  Any help appreciated.

  By the way... I have searched for hours on forums, web sites, etc., with no clear solution.

  Thank you

  Interesting,.

  of your screen grabs, it definitel; appears as if you have only 2 licenses - as stated above, however, if your license covers only 6 processors, you could have used the additional licenses on them.

  It is really worth to check that, and if it is not the case, get your hands on VMware and ask why the additional licesnse does not appear in your portal.

• How to test an ESX host

  What are the options for testing performance on ESX hosts?  Are there models of good OVF or vApps for ESX hosts test to determine their ability to stress?  For example, you want to determine how many virtual machines can run safely on a physical machine - is there an OVF template that will peg the CPU, memory usage usage and access hard drive at startup that you run a bunch of one host and one model OVF who will report on the usage statistics?

  Are there other (free) ways to stress tests of your physical servers?

  Thanks for your comments

• You can restart nfs storage WITHOUT having to reboot ESX host?

  Hi community

  I wanted to know what your experience has been reset to the nfs storage devices WITHOUT having to restart the ESX servers. I can stop the virtual machines that use the storage, but would like to avoid off ESX hosts as they require a visit to the data center for put in operation and I can do all the rest of the House.

  My options are either then restart the ESX host (that I can do it remotely of course) or the ESX Server restores in the nfs storage when it is up?

  This is the first time such a restart will be required so I use

  this as a learning experience and the VMs on those ESX hosts are not

  criticism.  (although don't tell users which.) )

  Thanks in advance

  Yes, of course you can.

  ESXes automatically reverts to the storage.

  Could someone please let me know why the reboot is happening?

  You can also drop in the newspapers of the host-d and/or information provided by a dump of support?

  My suspicion is that you can have something material related current. Have you checked the hardware section of the cilent VI or the HP tools?

• Reboot the ESX host as possible while on VM snapshots exist?

  Can you safely do a reboot of a host ESX VM there was on this host which are off (of course), but have a snapshot exists at this time?

  Because we restart some ESX host but you also have to install some Windows updates on the virtual machine on these hosts. Normally, we take a snapshot of the WM, install updates, restart, check if everything is working fine, and then remove the snapshot. But after a reboot the ESX host we also check if the VM have started and are working very well. In this case, it would cost me 2 restart and check for WM

  When I could do the snapshots, installation of updates, power off the virtual machine, reboot the ESX host, turn on the virtual machine, all check and then delete the snapshots, it saves me time. Only thing I don't know and can't find is so it record to make a snapshot is by restarting the EX host and if the snapshot can be deleted after reboot normally.

  Welcome to the community,

  don't worry, a restart of the host is quite VMs, regardless of whether they are active or not snapshots.

• How LUNS presented to an ESX host

  Dear team,

  How to confirm weather LUN is presented to an ESX host?

  We asked our team to SAN map a 900 GB LUN to one of the esx host, these people have done enough for their purpose (e.g. zoning part etc.) and confirm the same thing for us. We rescan the HBA, still, we are not able to see the same thing. SAN team asked us to reboot and check, but it's prodcurion esx box we will not be able to restart, so I want to confirm end VMware, is it possible to confirm weather esx is able to perceive the lun or the requested LUN is delivered correctly to an esx host, needs your help to understand this issue.

  concerning

  Mr. VMware

  If you need create a vmfs on this lun data store, then you can simply follow the add storage wizard via - see this link for more information/screenshots: http://www.vmadmin.co.uk/vmware/35-esxserver/109-esxvmfsdatastore

• How to balance IO SAN controller between my ESX host?

  Hello good community.

  Question about SAN controller i/o balancing between my ESX hosts.

  I've identified the controller A and B controller on my SAN, HP EVA 6100.

  The controller has 50001FE1 500E1208

  Controller B 50001FE1 500E120C

  But when I go to "Storage adapters", then "Manage paths" by vmhba and I'm lost.  Policy of LB is fixed.    Then I see:

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 * status: active, preferred

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d

  If the first two on my controllers, don't know about the bottom two WWWN however, can someone who knows HP EVA help here.

  Also, I am very confused regarding mirrored ports and the need to be cautious when balancing the way between the controller.

  Which would be great if someone could give me a few white read books on it, the same and also fair knowledge base articles explain how to approach the above and examine the virtual machines as well.

  Not too big so... just small forum post I raised here... It will be useful someone help to get a dialogue going.

  What I do with my EVA, is having different LUNs (Datastores) manually selected a path preferred in command mode.  For example LUN 1,3,5,7 are on path then that lun 2,4,6,8 are set on Channel B.  This means that all your LUNS are also responsible.  On the ESX side each of my machines has 2 HBAs each with 2 paths that it looks like your Setup.  Here's what I think looks like load-balanced:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

  ESX02-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - MON 5, 6

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - MON 7, 8

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - LUN 1.2

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - LUN 3.4

  It might not even be necessary have a configuration of blancing of load complicated if you produce not enough IO to saturate your current configuration.  You can just keep it like this:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

• How a VMGuest can see a number of physical ESX host processor

  Hello

  Not sure if this is expected behavior or not, but I have some application that runs from a linux machine to vmguest in my cluster Vsphere 4.0 U1 that is able to see the number of sockets processor busy on the ESX host that it is currently at. I never saw that happen up to now on another system in our environment. On Linux operating plan, when you run the "cpuinfo", the show only reviews the number of virtual processors assigned to it. I don't know how this program is able to see all the way down beyond the virtualization layer to the actual physical hardware layer on the esx host.

  My first thought was that this was triggered after the installation of the VM Tools on the guest operating system, but even after turning off the service tools you can still see the real taken account on the host computer.

  Can someone explain to me how this is possible?

  Thanks for any info you can provide

  Regardless of the tool that allows you to watch the CPU I have a strong suspicion about what is happening here.
  The exact CPU type in/proc/cpuinfo is listed: "AMD Opteron Processor 6164 HE.
  I guess that the tool you are using has some knowledge (using an internal list of program or by retrieving this information somewhere on the internet) that this CPU has really 12 hearts and he only relies on it and reported that the machine has 12 cores, instead of looking at what is really reported by the operating system.
  So, he just does not have the right to work and is not aware of virtualization.
  In any case, it is not really able to look directly into the hypervisor.

  $AllVMs = get-View - ViewType VirtualMachine. Where {-not $_.} Config.Template}

  {ForEach ($VM)

  $Details | Add-Member-Name name-value $VM.name - Membertype NoteProperty

  }

  You can try like this

  $MyCollection = @()$AllVMs = Get-View -ViewType VirtualMachine | where {-not $_.Config.Template}
  
  foreach ($VM in $AllVMs) {    $Details = New-Object PSObject    $Details | Add-Member -Name Name -Value $VM.name -Membertype NoteProperty    $Details | Add-Member -Name Host -Value (Get-View $vm.Runtime.Host).Name -Membertype NoteProperty    $Details | Add-Member -Name Datastore -Value ([string]::Join(',',($vm.Datastore | %{Get-View $_} | %{$_.Name}))) -Membertype NoteProperty    $MyCollection += $Details}$MyCollection
