• New Vcenter server and host add

  Hello, we are planning to create a new server Vcenter.  Had a bunch of weird issues with Vcenter.  Vcenter 5.1 on Windows running.  have not decided if we will use the VCenter, or create a new virtual machine from Windows to Vcenter again but I don't think that will count for my question.

  My plan is to turn off HA and DRS on the old server Vcenter, then remove a host from the old server Vcenter, and then add this host on the new Vcenter server.  Then just repeat the process for each host.

  My question is, should I turn off any virtual machine running on the hosts before removing the old server vcenter?

  If I remember correctly you have not, the virtual machine must remain in place and running, no connectivity should be lost and users should not not the difference.  We plan to do this off-peak hours, but there are always a couple of vm that are used 24/7.  It would be therefore rather not have to stop first.

  Thank you

  Hi defrogger

  Yes, it's the right way to migrate a new vCenter ESX Server.

  Disable HA/DRS and then disconnect the ESXi, vCenter server and plug them into the new vCenter.

  By disabling the DRS, you will lose the Resource Pools. So its maybe you assign only manual DRS.

  Another thing that many people forget are the options of the virtual machine on the cluster options. they have been set up again on the new cluster.

  BTW. There is a guide of vmware:

• vCenter Server and Manager on the same virtual machine and on the same host ESXi update that they manage

  Hi all

  I have a question to which I did not respond.

  I have an ESXi 5 on Proliant DL380 G7 server host. I want to install vCenter Server and Manager Update on one of the Server 2008 R2 VM on the same host. I know it's possible, but my question is how Update manager will provide updates to the same ESXi host it will run on? The update is applied every time host must spend in maintenance mode and power off the virtual computer running on this subject which means he'll kill VM where vCenter Server and Update Manager is running and the update will fail right?

  Is that possible at all or the VCS and UM such as a virtual computer operating point is updated to other guests if you have them or vMotion as VM to another host when you want to update the VCS and UM host is running?

  Thanks in advance.

  It will not work.  You will need at least two hosts.  This way you can vMotion the vCenter VM to another host.  From there, you can use VUM.  Otherwise, you will need to patch the host as a stand-alone host.

  See below for patching a standalone host

• vCenter Server and SQL server affinity

  Is there a best practice for the rules of the affinity between a vCenter server and a SQL server VM in the same cluster?

  Thank you

  I think that separation would be mainly for safety.  Maybe to keep the SQL Server in a broadcast domain separate servers so that they do not receive all the Windows usual chatter.

  Most of the environments I've worked have been small enough to either do not have more than a few tens of machines virtual hosts/250, or overworked staff that cannot be dedicated to security, s/n, etc., and the decision was taken to run the DB in SQL Server on the same server as the application of vCenter to reduce the complexity and rely on the host/network/SQL Server security and properly locking to the bottom of vCenter.

  As I said before, there is a good chance you won't notice a difference, performance wise, anyway.

• Is it possible to run vCenter Server and AUVS in the same database?

  Hello. My client has vCenter Server and VUM installed and running in the same database. Yes, the same database (not only same server database) and the same ODBC (ODBC VUM is 32-bit only).

  My question is whether it is supported or not and I would like a source VMware information, not only "it works fine for me".

  I can't find any definitive info on this VMware. Only something to wave in the installation and upgrade guides about or not to run in the same database ' ' (I guess they mean 'server') and it seems that the recommendation is to separate them for the 'large environments,' whatever that means.

  The environment vSphere 4.1 is currently, and there are about 20 guests and 150 virtual machines.

  If it is not supported, I guess the best way to go is to reinstall both from scratch?

  Thanks in advance!

  / Anders

  Yes, it is a supported configuration.  Since VUM and vCenter using different tables, you can share the same DB

  The database of the update manager that you use can be identical to the vCenter Server database. You can also use a
  separate database, or you can use existing database clusters. For best results in a large scale environment, you
  must use a dedicated Update Manager database that is located on one computer other than the
  the vCenter Server system database.

• Host migration of the most RECENT vCenter Server to the old version

  Has anyone moved hosts currently connected to a newer version of vCenter Server 4.1.0 to an older building?

  Example - 4.1.0 build 345044 to 4.1.0 build 208111

  If you what have been your experiences (tips and tricks) with this type of migration?

  Thank you

  Matt...

  should be no problem.  Disconnect the old vCenter host, then delete.  From there add the host to the new.  They vpx agent will be reinstalled and your host must be added to the inventory without problem.

  You will lose good historical data...

• vCenter server and ESX versions

  Hello friends, can you please answer these questions:

  (1) what additional features we get in vCenter server Essentials

  in comparison with vCenter server Standard?

  (2) is it possible to have some ESX servers upgraded to 4.0

  3.5 in our infrastructure and some left at the same old ESX 3.5 level? Do

  they coexist? If they coexist, managing servers ESX 3.5 and ESX 4.0 with

  the same server vCenter 4.0?

  see you soon

  the same server vCenter 4.0?

  Yes, but you must have a license for 3.5 systems running server. The vSphere vCenter must be configured to point to this license server. One solution is to install this on the server vSphere vCenter and decomission license server when all the ESX servers running 4.x.

  Another option is to keep the old server licenses running and just the new vCenter for that one pint.

• Difference between vCenter server and ESX server

  Hello

  I'm new to the development of VMware. Can you please explain me how ESX server differs from the VirtualCenter Server?

  According to my knowledge, ESX server is the one on which the real images are created and deployed while VirtualCenter manages ESX (one at a time) servers. ability to manage multiple ESX servers, both 'vSphere' a.

  My understanding is correct. Kindly answer my question.

  ESX (later - ESX4) is a system of bare metal operating that you can install directly on your physical hardware. This is the hypervisor layer that helps you to run multiple virtual machines on a single piece of material. The heart of ESX is the VMkernel which does all the magic (resouce management VM.. .and much). Talk about vCenter (previously Center Virtual Server) is a management application that you can install on a separate physical computer (you can even have a virtual vCenter). Once your vCenter is allowed, you can begin to manage the ESX servers.

  There are two ways to manage ESX. One is that you can directly connect to your ESX Server with root password and manage it. Otherwise, connect the server vCenter, add the ESX Server so that your vCenter it manages.

  vCenter resembles a management station from which you can manage your multiple ESX servers.

• The scrapping of vCenter server and start over, which vCOps think?

  So have had some problems with our box of vCenter, VMware support has not been able to help and we're finally at the point where we want to just start over with her.

  The plan was to break the bond of vCOps, rebuild, add it again and continue with life.

  My question is how its data is collected by vCOps and he re - create all objects or it will continue to collect and build on what we have collected for the past year.

  Did someone done this before when running vCOps?

  vCops key off the ME of the virtual machine, what will change if you wipe vCenter... so your old data will still be there, but all virtual machines will be considered as new objects and old data will be "failed".

• VCenter Server disconnects guests after 1-2 minutes

  Had a strange little problem going on because all my 4 ESXi (not upgraded to U1 yet) switching hosts offshore to put on a new UPS system - if I connect it with VI client to our server Vcenter (Win 2003, VCenter 4) not yet upgraded to U1 consistantly unplug all 3 hosts at the same time after 1-2 minutes.

  Network connectivity is very good between the VCenter server and hosts, if I connect directly to one of the hosts he will stay connected properly.

  Impossible to find errors in case the viewer connects

  Ideas - I have a ticket open with Vmware support, but am struggling to get an answer at the moment.

  Thank you very much

• VCenter Server first to 5.5.0U3b update and later update of VMware ESXi ESX / will I have problems?

  Hello

  have trouble when I first updated my signature single vCenter Server and later update my vSphere hosts?

  A vCenter Server Version 5.5.0U3b should be able to manage vSphere Host Version 5.5.0 GA, right?

  Kind regards

  Roland

  The vCenter Server 5.5 update 3 b can manage VMware ESXi ESX release GA to 5.5 5.5 update 3 b, take a look: VMware product interoperability Matrices

  BUT, according to the interoperability matrices and vCenter Server 5.5 update 3 release notes, VMware strongly recommends you upgrade your hosts to 5.5 update 3 b, see:

  What's new

  • Update Support for the SSLv3 Protocol is disabled by default
    Note: In your vSphere environment, you must update vCenter Server vCenter Server 5.5 update 3 b before the update to 5.5 ESXi ESXi update 3 b. vCenter Server will not be able to manage 3B ESXi 5.5 update, if you update ESXi before update vCenter Server to version 5.5 update 3 b. For more information about the sequence in which vSphere environments must be updated, see KB 2057795.

  • VMware strongly recommends you update ESXi hosts to ESXi 5.5 update 3 b management of vCenter Server 5.5 updated 3B.

  VMware does not recommend the reactivation of SSLv3 because of the vulnerability of POODLE. If all you must enable SSLv3, you must activate the SSLv3 Protocol for all components. For more information, see

  KO 2139396

  .

  • Resolved issues. This version of vCenter Server 5.5 update 3 b solves the problems that have been documented in the resolved issues section.

• The host is licensed with VMware vSphere 5 Standard. The license of vCenter Server edition doesn't support VMware vSphere 5 Standard.

  So I disconnected a host to vcenter server and now I get this error message when I try to reconnect to this host.  The host has been previously connected without any problem.  Vcenter servers as esxi are 5.5.0.  Anyone had any experience with this?

  Thank you.

  Unfortunately, I can't tell you for sure why it worked previously. Maybe it worked with an earlier version, or hosts have been added while vCenter Server was still running in trial mode. Anyway, if you have a license of Essentials for vCenter Server, you must also license processors Essentials the Essentials version is sold as a kit.

  Hello

  Resolution

  Cause

  This problem can occur if an ESX host's IP address is changed while being managed by vCenter Server.

  Check the cause

  To check the cause of the problem:

  1. Log in as root to the ESX host using a SSH client.
  1. In the file etc/opt/vmware/vpxa/vpxa.cfg, find the IP address of the host. The entry looks like:

     
     10.21.48.121
     

     Note: for more information about editing the files, see installation in VMware ESX configuration files (1017022).

  Troubleshooting

  If the IP address is incorrect, perform the following steps in order. If the operation does not resolve the problem, continue to the next step. Don't skip a step.

  1. Disconnect and then reconnect the host:
  1. Right click on the ESX host in vCenter Server and click Disconnect.
  1. Reconnect the ESX host in vCenter Server.
  1. Restart the VirtualCenter agent on the ESX host:
  1. Stop the service of vpxa with the command:

     # service vmware-vpxa stop

  1. Open the /etc/opt/vmware/vpxa/vpxa.cfg file in a text editor and correct the IP address of the ESX host.
  1. Start the service of vpxa with the command:

     # service vmware-vpxa start

     Note: for VMware ESXi, you may have to restart all the management agents. For more information, see restart the agents on an ESX or ESXi Server (1003490) management .

  1. Rebuild the VirtualCenter agent on the ESX host configuration file:

     Attention: this step removes all the Statistics counters historical host and the virtual machine. If VMware ESX host is running in virtual machines that starts in a permitted CVS environment, you maybe won't be able to add the host without stopping the virtual machines first.

  1. Right click on the ESX host in vCenter Server and click Disconnect.
  1. Remove the ESX host disconnected from vCenter Server.
  1. Backup the file vpxa.cfg with the command:

     # mv /etc/opt/vmware/vpxa/vpxa.cfg /etc/opt/vmware/vpxa/vpxa.oldcfg

  1. Add the ESX host disconnected to the server vCenter inventory.
  1. Run the following command to view the contents of /etc/opt/vmware/vpxa/vpxa.cfg and confirm that the host IP address is correct:

     # cat /etc/opt/vmware/vpxa/vpxa.cfg

• Cannot add the ESX 6.0 host to vCenter Server 6.0

  OK, I'm testing laboratory a vsan 6.0 cluster.

  I have my running 6.0.0 esx hosts and vcenter server is 6.0.0 also.

  I have the services platform on a virtual machine and vcenter on another. I was able to create a data center, then a cluster below.

  Then I went to try to add a host to my group and I get this error...

  Failed to contact the specified host (hostname\IP). The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond.

  
  

  Per this KB: KB VMware: Add a host VMware ESXi/ESX from VMware vCenter Server fails

  
  

  I confirmed that my vcenter server and platform services server can see all esx hosts. From the vcenter server, it can ping the host esx and PuTTY can access all of them. I even installed the client and it can connect to all esx hosts. I used the netbios name, IP and FULL domain name and they all work.

  I have only a single subnet, so this isn't a problem. DNS resolution works in all areas of both sides, vcenter esx hosts and host esx to vcenter.

  
  

  I am quite puzzled.
  

  
  

  
  

  OK, after working with VMware on this issue, I think that I thought about it.

  All my hosts are DL360 G6 servers.

  My hosts are run the same build «VMware-ESXi-6.0.0-2494585-HP-600.9.2.38-Mar2015.iso» ESX Downloaded from HP.

  All buildings are in trial mode.

  After placing a call to VMware, they had me build some ESX VM, the services of the platform and the vcenter VM on an ESX host. We suspended because it took all day to go upward.

  Once I woke up all the parts (sql server, esx vm, server platform & vcenter) in virtualization nested, I created my data center, then Cluster then added the ESX host.

  The hosts added properly, no error. Then I remembered when I installed ESX inside a virtual machine, I am angry that the iso, I had the habit of HP does not work in my VM nested due to virtualized hardware.

  Then a fire came into my head. We will rebuild all of the physical cluster but NOT use the CV provided the iso file but use VMware provided iso file "VMware-VMvisor-Installer - 6.0.0 - 2159203.x86_64.iso".

  I did it today. I have rebuilt all hosts with the provided iso file VMware ESX...

  Spun SQL Server vCenter, service platform, all VM VM VM you need. My AD & DNS VM are on another server, so he has been upwards all the time.

  Connected to the web interface (yuck!).

  Created my data center...

  Created my Cluster...

  Add all my Cluster hosts.

  All of this worked!

  Therefore, if you encounter the same problem, I'm plan to generate your with the provided iso file VMware ESX hosts and try it. In my case, the provided HP iso file didn't work properly for me.

  I also downloaded the iso file of HP 2 other times to make sure and do a validation test and it did the same thing.
