• 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 restart vm esx host in different work HA?

  I understand that VMOTION = migration hot virtual machines on esx hosts. So, if HA uses VMOTION, how HA restarts VMs on another esx host when the original, we're out of service?

  I guess it will take to create an another vm on the available host using the same on the san .vmx file?

  IF we were to do it manually, it will be just import a virtual machine to another host on the right?

  Correct me if im wrong?

  A bit confused on the works of the HA behind the scene

  See you soon!

  VMotion and HA are not related or dependent on each other.

  (1) again, this works because the virtual machines themselves live on storage shared and not bound to a specific host ESX (i). ESX implements non-persistent locks on a specific virtual machine, when the host goes down, these locks will eventually timeout. HA will launch the failover, allowing it to reregister the VMs failed and restart. Manually, you can walk through this process by the presence of a virtual machine that lives on the shared storage that runs on HostA, then it turned off and cancel the registration of the virtual machine. You would be so I re-register on HostB and turn on, and voila, you've just simulated a ghettoHA.

  Here are a few extra links/documentation which may be useful for you better understand it:

  HA said:

  http://www.VMware.com/products/VI/VC/HA.html

  http://www.VMware.com/PDF/ha_datasheet.PDF

  vMotion explained:

  http://www.VMware.com/products/VI/VC/VMotion.html

  http://www.VMware.com/PDF/vmotion_datasheet.PDF

  (2) vMotion as you know already, performs a live migration of a virtual computer between two hosts, where as HA you will get some downtime of the virtual machine while it is rescued. The key is HA doesn't provide true high availability, it's just faster to recover. If you are looking for a true HA, take a look at VMware FT www.vmware.com/files/pdf/resources/ft_virtualization_wp.pdf

• 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.

  Your opinion is requested.

  Thanks for your advice. He agrees with your saying that the start / stop sems to be buggy.

  It's only disable it every time that you enable VMware HA.

• vCenter is virtual server - how to upgrade ESX host?

  Our vCenter server is a virtual server.  I've been thinking how to run update manager on the host ESX, vCenter is sitting on.   The only thing I can think of is to use the VMware Converter stand alone app and move the vCenter server to another ESX host and then start vCenter / Manager Update on the new ESX host to update the original ESX host.

  Is there an easier way?

  you have a shared storage?  If so, go to the host computer running the vCenter VM on, turned off, make a note of the data store that it is, remove the inventory, go to another host, browse the data store, find the vmx file, right-click "add to the inventory.

  .. .or you can use VMware Converter to move the VM vCenter.  Another way would be to turn off the VM vCenter and do the upgrade using the CLI interface.

• 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

  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 - 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
