• 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.

  It turns out that the problem is that our agile took place of the intellectual property that it wasn't supposed to and it's a double that esxi host IP. Very strange behavior. But it's the solution.

• Cannot add a host disconnected from a cluster

  Hi people,

  I have a very strange problem - 1 my cluster host is always shown as disconnected. When I connect it manually, it is coonected, begins to configure HA and after that which is disconnected again.

  Deactivation of HA - same problem. He remains connected seconds (up to a minute) and then again once disconnected.

  You have any ideas?

  DNS is a good first suspect, but it can also be the management agent itself.  The type of service console

• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.

• 5.5 ESXi hosts disconnection of the vCenter 5.5.0b

  Good evening.  I recently deployed some new hosts HP BL465c G8 running the HP OEM install ESXi 5.5 (not the one just released 02/18) and the two hosts have been disconnect from vCenter four times in the past week.  I can sometimes connect to the host via ILO and restart the vCenter agent, but more often without having to start the host hard.  In addition, one of the VMFS5 content of the data store disappeared and the virtual machines residing on this data store have declined because the hosts could not find the configuration of the virtual machine files. Strangely enough, the data store showed spaced used and I could see all the directories within the CLI, but not vCenter client or Web-based Client.  I have two tickets to windows with VMware from HP support team, but I wanted to know if someone had a similar problem.  I'm tempted to rebuild with the latest OEM installation or rebuild as 5.1 or 5.0 if version 5.5 is not fully cooked.  Thank you.

  Scott

  The issue proved to be the OEM HP install and specifically the pilot v1.1.7 for HBA QMH2572 adapters that it contains.  We have rebuilt our 5.5 ESXi hosts using installation OEM HP published 02/14 (contains recommendations
  v1.1.12 pilot) and that solved the problem of stability.

• How to remove a host disconnected?

  I have a Cluster with 6 runing ESX 3.5 hosts and two of these hosts are disconnectd and no longer works (material has disappeared), and I want to remove these two my cluster, so I clicked on delete and I got an error:

  Unable to reach the specified host (host06.domain) this...

  So, I want to know how can I remove a host disconnected from my Virtual Center.

  you have a SQL DB?  If so, perhaps this will help you

  http://sosleepy.TV/2010/02/19/remove-an-VMware-ESX-4-host-from-vCenter-by-directly-deleting-the-host-from-the-SQL-database/

  The host in question no longer exists?  If so, you can also try the source edition licensing and remove your vCenter host.  Then restart your management agents

  service mgmt-vmware restart
  

• Restart Management Agents... now does not

  Hi guys

  I had to do some troubleshooting and recommendations I restarted management agents (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003490( )

  To restart the management on the ESX host agents:

  1. Mgmt-vmware restart the service.

  2. service vmware-vpxa restart.

  but after that my host is red and shows does not and all the VMs disconnected say system...

  How can I recover it?

  Thank you very much

  This is normal and should recover in a few minutes.  You should always be able to connect to your guests and the host without any problem.  Restart management agents to disconnect and reconnect the host and VM on and in the inventory.

• ESXi hosts are disconnected from the vCenter (5.5)

  Hi all

  We have a little problem with our vCenter.

  We have two hosts that are connected to the vCenter, unfortunately, they are listed as disconnected.

  It seems that the problem are the SSL certificates on ESXi hosts that are no longer valid.

  If I replace the old certificates with new ones, that I have to restart the ESXi host, am I right?

  If so, that's the problem.

  We do not use any what automatic vMotion and as long as the hosts are not connected to the vCenter I can't manually, move right?

  Is it possible to connect hosts to vCenter without SSL?

  Sorry for my bad English, I'm not a native speaker.

  See you soon,.

  Johannes

  You need to replace the ESXi host SSL certificates.

  See the Docs for the replacement of ESXi Cert below.

  ttp://www.BlueBox-Web.com/2013/04/18/replace-ESXi-certificate/

  Documentation Centre of vSphere 5.5

  I had regenerate the ESXi 5.5 SSL certificates, which I did without any stop to virtual machines.

  Certificate replacement process can change based on the esxi version.

  According to the Doc, vSphere 6.0 Documentation Centre ESXi6 host must be rebooted to replace certificates.

  Anyway, in current state disconnected, you can try to regenerate the self signed SSL certs, restart management agents and try to reconnect host in vCenter.

  Thank you

• ESXi hosts disconnected/no response in Vcenter after upgrade (4.1 = > 5.5)

  Hello. I'm upgrading our current infra (hosts/Essential licensing Vcenter / 3 ESXi 4.1).  vCenter Server has been upgraded OK, so I started to esxi upgrade hosts one by one.

  Upgrade process is OK, but after the reboot, upgrade marked as "not responding" in vsphere client server. I could ping this host and connect via ssh.

  When you try to reconnect the client host, got a strange error "this edition of vCenter only supports 3 host (s) in the inventory. After 3-4 hours of nothing to host

  has begun to show ok. After upgrading a second host, the same situation. I don't understand, how to solve it without waiting for another 4 hours.

  Restart of host management agents does not help.

  I remember I have a similar situation in the past where the number of licenses does not update as expected, i.e. required some time. What helped was to restart the server vCenter Server in my case. Maybe worth a try!

• ESXi disconnects from the vCenter

  Hello VMware,

  I have some problems with ESXi 4.1.0 (Build 260247) disconnect vCenter. I am currently evaluating Vmware View. I have no problem connecting to an ESX host to vcenter. When connecting vCenter ESXi host host will connect for about a minute and then disconnect. VCenter, Active Directory, DNS, DHCP, and ESXi host is all on the same network without any firewall between the two.

  I have an I tried by using the knowledge base article titled "Diagnose an ESX Server that is offline or does not respond in VirtualCenter" without success. I can connect the ESXi host with ssh and ping various servers on the network using dns and ip addresses.

  Is attached a copy of the message, pass and vxpa journal of the ESXi host.

  Any help would be greatly appreciated .

  Since the log files, it seems that you use vServers 4.0.

  Section for VMware VirtualCenter Agent, pid = 56646, version 4.0.0 build = build-208111 =, = exit option

  The host ESX (i) 4.1 require vCenter Server 4.1, this is why you must upgrade to vCenter Server to make it work.

• Cannot disconnect from Imessage. There are Greyed out.

  Hello

  I have always been signed out imessage on my MB pro since the update to el capitan (10.11.5), the lion, a month ago. I managed to open a session and during this time by going to Preferences-> account and disconnection.

  A few days ago, I decided to log in Imessage to try again. After playing with him for a few minutes, I decided that I don't really need to use this feature and tried to disconnect. I couldn't do it. When I go to Preferences-> accounts, I can see my Apple ID, but there is no option to activate/signout etc. It displays a blank page to the right. http://i.imgur.com/SowbzCl.PNG

  Please let me know if there is something I can do.

  Thank you

  Hello sedentary_of_state,

  Thank you for using communities Support from Apple!

  It is my understanding that you are not able to sign Messages.  I have some suggestions that will help you if all goes well.

  The first thing I would do, it's what is on the backup computer.  Nothing that I will propose should result in no data loss, but it's always a good idea to have a backup.  Your computer has software called Time Machine.  It is a fantastic software for backing up your computer.  Information on how to use Time Machine is available here:

  Use Time Machine to back up or restore your Mac.

  It is important to try to isolate what is responsible for this.  The first thing to do to help isolate what is causing the problem is to start the computer in what is called Safe Mode and see if the problems still occur.

  Start in safe mode

  1. Choose the Apple menu > shut down.
  2. After your Mac stops, wait 10 seconds, then press the power button.
  3. As soon as you hear the startup tone, hold down the SHIFT key.
     You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.
  4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

  Once the computer is running in safe mode, see if you can sign by opening Messages, and then click Messages > Preferences > accounts, and then click Sign Out. If you are able to disconnect, go ahead and restart the Mac normally.

  Have a great day!

• Windows Media Player 12 will not play mp4, mp3, wmv files through IIS hosted local site when the PC is disconnected from the Internet

  I have an IIS Web site 6.1 on local 32-bit Windows 7 machine that serves HTML and MP4 videos via Internet Explorer on the local computer.  An internet connection is not necessary because it is all local storage and local accommodations through IIS.  IIS is configured to serve the MP4 videos in the form of downloadable files, don't not streaming somehow.  I have the right MIME type ".mp4" with the installation of "video/mp4" in the IIS server, so I don't think that's the problem.

  When the machine is connected to the internet, by clicking on a video link MP4 in any HTML page served by the local IIS server results in Windows Media Player opening and playing the video in its own window.  However, when the Ethernet cable is unplugged, by clicking on the same results of video link MP4 in Windows Media Player by opening its own window, and then display this error message:

  Windows Media Player cannot play the file.  If the file is on the Internet, connect to the Internet.  If the file is on a removable storage card, insert the storage card.

  It's almost as if Windows Media Player has a bug and since it accesses this media file via a URL, but the machine is not connected to a network, he thinks that this file is unplayable.

  When the Ethernet cable is disconnected, the local IIS server is still all the HTML code and ActiveX content except for media files.  I also tried to access MP3 and WMV files via the IIS server to see if Windows Media Player will open those when the computer is disconnected from the Internet.  These caused also Windows Media Player files display the same error message.

  I tried the VLC (VideoLAN) Player after changing the property file in VLC of WMP for .mp4 files extension.  With VLC installed and the extension changed to VLS property, I can download/open the MP4 video using the link in the web page served by IIS all when they are disconnected from the internet.  The only thing I can't do is get VLC player to open and play the video simply by clicking on the link in Internet Explore web pages served by the local IIS server.

  I would like to make use of Internet Explorer and Windows Media Player with this IIS server that serves the MP4 videos rather than using VLC player.

  Thank you

  Michael Rayman

  I finally found the answer to my problem:

  When they are disconnected from the internet, mysteriously, Windows Media Player 12 requires that you check a checkbox in tools > Options... > zone settings tab player called "Internet connection (ignore the other commands).  Once this box is checked and the settings saved on APPLY, then Windows Media Player 12 will play videos served by the local IIS server on the same machine, while disconnected from the Internet.
