• 5.1 ESXI host disconnects the vcenter, when reconnected SSL fingerprint has changed.

  I'm having a strange problem with only 1 of the 5 hosts connected to a cluster inside of vcenter. A host disconnects randomly vcenter.

  I right click on the host and select Connect. I get the default value to the warning that 'reconnect a host will replace any change in management of resources that have been made directly on the host... ". ». I select Yes.

  Then, I get an error

  I suspect that you posted your question to the wrong thread

  This requires only a minor change to the script above actually.

  Something like that

  $groupName = "group"$accountName = "user"$accountPswd = "password"$accountDescription = "A user"
  
  $esxlist = Get-VMHostforeach($esx in $esxlist){    Connect-VIServer -Server $esx -User root -Password "password"
  
      Try {      Get-VMHostAccount -Id $groupName -Group -ErrorAction Stop | Out-Null    }    Catch {      New-VMHostAccount -Id $groupName -GroupAccount | Out-Null    }

• ESX 4.0 U1 host disconnects the VC

  Hey people,

  I'm working on my test bench trying to put on after a stop of 6 months.  I changed my ip address, in everything from virtual machines, host esx (alone) and iscsi (openfiler).  I could work very well using webaccess.  My VC works very well.  So my DC.  All are virtual machines.  The problem is that I connect to the host at the VC and all is well for anywhere from a minute to three minutes and then VC loses the connection to the host.  I clik on the host esx and clik 'connect' and I connected again for the above period.  I unplugged the host several times and then reconnected.  No change in problem.  I searched some vestige of the old ip addressing, which could cause the problem but can't find anything that I have not changed.  I have not stopped all my VMs and restarted the esx host.  I restarted the services and vpxa mgmt.  Someone has an idea of what I'm missing here?

  , You update the DNS records for the host ESX and vCenter Server?

• ESXi/ESX host disconnects vcenter Server 60 seconds after the connection

  Hello guys,.

  I recently made some changes to my VMware Lab.

  I'm under vCenter 5.1 with several hosts of ESXi 5.1.  My vCenter ran on one server ESXi 5.1 until I recently migrated there in a window of Windows 8 running VMware Workstation 9.   The vCenter is running normally and I am able to add hosts in stock, but they disconnect after approximately 60 to 90 seconds.  I believe that this issue is that the heart beats that are sent by the host do not reach the vCenter (port 902), I think that it is similar to the issue discussed in the following KB:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1029919

  Here are my questions:

  1. the article describes download wireshark and run scripts.  Is there an easier away from do?  I'm literally just checking this single port of the ESXi host, there is no equivalent for telnet from an ESXi host?

  2 VMware Workstation 9 block ports or run its own firewall any?  Since this vCenter worked perfectly when running on the host ESXi 5.1 we know this isn't a firewall on the virtual computer problem, I have also checked the Windows 8 machine running VMware workstation and have verified that the windows firewall is disabled.  Windows firewall is not the issue. 

  Thank you

  Duncan.

  Just a quick question. A fact change of IP address of the server vCenter with migration of VMware Workstation? Maybe http://kb.vmware.com/kb/1008030 is related to the question!

• Disconnect the Vcenter/Cluster host and addition of new implications of Vcenter.

  All,

  We had to rebuild our vcenter on a separate box, because the database on the old one is completely messed up.  Successfully, we have disconnected hosts stand alone and added to the new Vcenter inventory without problem.  We wanted to know if there are problems with HA/DRS power off and disconnect a host of vcenter which is currently in a cluster.  Then add it to the new vcenter to manage.

  Thank you!

  No problem.

  Simple disable HA, tie your host for the new Victoria Cross, and then reactivate the cluster functions.

• running in vCenter Server, ESX, how clean the vCenter host?

  I hope that the topic of the thread makes sense somehow.

  We have vCenter Server works like an ESX VM, for now on local storage, but eventually it can be moved to the SAN storage.

  To clean up our ESX host, we use Update Manager.

  How does the VUM to sanitise the host that is running the vCenter Server VM?

  What should I do to have AUVS to clean up the host that runs the vCenter Server VM that is running VUM?

  Thank you, Tom

  If everything works on local storage, you can simply make your updates via esxupdate on the command line.

• Host disconnected from Vcenter. cannot restart both agents

  Hello

  Following this thread: http://communities.VMware.com/message/1993369#1993369

  After 1:30 the host where the rescan HBAS was issued, became disconnected from Vcenter.

  I tried to restart the agent from the console, but he was hanged.

  I happened to have logged on esx, so I stopped the agents and restarted, but it hung for 1 / 2 h from "usbsarbitrator." I left.

  Looks like I need to restart the server, but I have the feeling that all the virtual machine running (OK for now) on this topic will be off and restarts automatically via DRS at best or not at all, if for some reason any DRS does not work (because of the issue of the host).

  To make matter worse, vcenter is running on this host at the moment.

  Is there a way to 'reconnect' vcenter to host this way can I vmotion all the VM on it before restarting the host?

  Thanks in advance

  Is you are using ESXi version connect the host using putty and run below command

  restart the /sbin/services.sh

• 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

  Howard

  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.

• Naming of the ESX hosts with the underscore. Best practices?

  I was curious as to what that the general eager to name the ESX hosts with underscores "_". I found an old post in 2006 related to it:

  http://communities.vmware.com/thread/64885

  In the thread, it is usually frowend against because she not compling with DNS internet naming standards. The underscore character is not recognized by the Web servers.

  He has been wondering if there would be no advantage to include similar underscore characters with no routable ip subnets, 192.168.x, 10, etc...

  If you have designed it correctly you already have your hosts on a subnet that is not routable, so you would get no real benefit.

  Beyond this thought experiment, there are problems with your esx host with ESX, vSphere, vCenter naming universe underscores?

  Just an info

  All my guests have underscore in them. I had to replace all of them with a dashboard because ESX 4.1 will not accept underscore after upgrade to the console.

• Lost my ESX host in the left panel? (Solved)

  My vCenter server lost my host list to left panel and leave VM only as attached picture:

  But I can't find this host left today and it is two VM was moved to a new folder.

  I try to take off VM the new folder, delete the new folder and try to add the new host with my exist ESX to retrieve the list of the Panel, but VC tell me: 'the name vmserver.point.com.tw already exist' refused to add this host.

• How to add a new virtual machine to the ESX host using the existing files?

  I need to implement a function clone without the use of cloneVM_task. I copied (a special copy) a set existing VM Directory Active Directory to a new directory and renamed copied all files prefix name of the new direcotry.  What task VM (reconfigVM_task, createVM_task or registerVM_task) command can I use to add that the new copied VM on the ESX host? I need to manually update the .vmx for new UUID file and other parameters?

  Thanks for any help.

  I think that as long as you have updated all the names to reflect the new clone you must be fine and on the first step, you will be prompted with a question.

• Set the time of ESX host

  Hello

  before that I have to download free 5.6 OPs of the trial, I used OPs 5.0.3 (Free Trial) in your Docs is States:

  "Time of the ESX host and the vCenter Server must be synchronized.

  In the Configuration without any server NTP tab I put a time but when go to Putty and connect to the host, and write the command 'date', the time is different from what I put.

  1 - is this problem due to lack NTP server?

  2 is it possible that I put the analytical UI VM and VM timezone to my zone schedule without host adjustment? (is this true?) (Is it that enough, I just set time zone of PAHO)

  Please help me

  Hello

  You must set the parameters of your ESXi host NTP.

  There is no timezoned in ESXi I know.

  Make sure when you look through the settings of Date and time on the ESXI host right now is what should be based on your local time.

  Let the time vC Ops to UCT. That should ensure the VAPP have the same time as the ESXI host.

  When you start the TIME you can check the time on the virtual computer is the same as hosts yoru.
