• vCenter Server down - what features are lost?

  I'm sorry if this has been answered before, I'm sure it is, but what I don't seem to find exactly what I was looking for when searching for it.

  If I lose the connection to vCenter, and I've got vSphere Enterprise more than licenses, which includes / functions I would lose as vCenter is down? Is it only the DRS and nothing else, or some other robot would be lost requiring a vCenter?

  Thanks again in advance, and sorry if this is a re-hash of old news.

  Main environment is 5.0 however looking to switch to 5.1.

  Hello

  If the vCenter server is down, you won't be able to vMotion, Storage vMotion, HA, DRS, Update Manager. Also you will not be able to user VDR or POS.

• vCenter Server Database - what's really in it?

  Hi all

  I was looking at a possible a 2.5 VirtualCentre 2003 R2 upgrade to a new version 2008 R2 / vCentre 4.0 server.

  I read in the upgrade guide that seems simple enough, but it made me think. What is actually represented in the vCenter database - as in, if I had to establish new ones without upgrading and simply type hosts into the new vCenter Server, what I actually would lose?

  Enjoy that probably said more about my lack of experience with this kind of thing but he had me wondering - the only thing I can think is a historic performance and alerts data? Server vCentre is obviously not necessary for the functioning of a group and DRS / HA configuration on the host (IDE) are pools of resources.

  Just curious really - is it useful the hassle of the upgrade, or should I better just to drop the existing server and starting from scratch?

  Thank you

  Chris

  Welcome to the community,

  you already mentioned the cluster configuration and historical performance data. Some of the things you need to rebuild with a new installation - according to your needs - are data centers. Clusters, Pools of resources, folders, roles, and Permissions, alarms... In the case where you have templates, you will need to re - register manually inventory,

• If authentication UNIQUE server restarted it will cut the existing user sessions?

  Dear team,

  We have installed upgrading Windows on the SSO server, before restarting the same I just want to confirm some users are already authenticated with SSO and connected to the VC by vpshere customer, if restart us the SSO server, then there will be no impact on the current user's session that are connected to the VC via vsphere client?

  Note: SSO, database MSSQL & VC server are installed on different virtual machines.

  Need your help on the same.

  concerning

  Mr. VMware

  No and after with the link below, if the user connected before SSO vCenter (with references use Windows Session) grave checked down, the user can connect again without problem even with SSO in offline mode.

• vCenter Server referenced in VMview

  Good afternoon

  Our environment VMview is centered around an old installation of ESX 3.5 with vCenter server of v4.0.0.10021. All of our ESX servers are 4.1i base and governed by a completely separate vCenter (v4.1.0.12319) server. My question is I want to gradually remove the old server vCenter, but as much as feared VMview isn't just "VirtualCenter servers" section that I need to change on the most recent vCenter Server? What should I be wary of?

  Kind regards
  Keith

  PS - I'm looking to upgrade ESX 3.5 to 4.1i, if anyone has advice or suggestions for this also which would help greatly - it seems straight forward enough, but 22 years that makes me a cynical beast!

  OK, I guess that the amount of work you need to do will be decided by your installation.   If you use complete desktop computers or clones associated with persistent desktop computers, you will need to go through the user data, http://communities.vmware.com/people/skg/blog/2011/01/01/moving-svi-pool-across-vcenter-server-keeping-user-data-and-ownership.

• What will be lost if I perform a new installation of vCenter Server?

  Hello

  We tried to upgrade our existing vCenter Server 4 to 5 without success.  The VC Server service is not able to start up.

  VMWare support staff has suggested us to perform a new installation.  We would like to know what information will be lost and must be reconfigured to the new vCenter Server?  We are OK to do not keep permeable Performance data.

  Thank you

  What you lose depends on what you have in vCenter.

  Models, Folders, Cluster configurations, pools of cluster resources, HA/DRS configurations, alarm settings

  clusters to store data, storage profiles, profiles of the host, historical events,

  If you use the vNetwork distributed switch,

  vCenter Distributed switching configurations will not exist in the new facility and

  need to be rebuilt before adding the hosts;   You'll probably need to convert those back

  the standard vSS on the hosts temporarily before adding them to the new vCenter...

  Basically... you lose all configuration except the configuration stored locally on the host computers.

  It is essentially the list of virtual machines and the stuff you see in the 'configuration' tab when you click

  a host.

  You will need to add the hosts as one of the steps in the installation of the new Victoria Cross.

  You will have the virtual machines stored on the host and resource pools that existed

  on the host at the time, vC was lost.

  However, when you move the hosts in a cluster, the 'Home' resource pools

  will be deleted.

• What is the best way to move another server Vcenter Server?

  Hello

  We have 3 nodes VMWARE running with VSpere 4.0.0 and a Vcenter Server 4.0.0. The server running the server Vcenter on disorders gives and must be replaced. What is the best way to move the VCenter server on the new server and keep all the settings?

  And is it possible to update at the same time to VCenter Server 4.0.1?

  Thank you

  Marcel

  There is no problem, I also think that it is the best way if you do not have a large environment - usually takes less time :-). Remove first the hosts of the other vcenter - this will make the vcenter agent to be uninstalled from the ESXs.

• What are the requirements for vCenter Server 5?

  What are the requirements for vCenter Server 5?  Specifically, I'm looking at the vCenter Server Appliance but it is set to 8 GB of RAM.  I hope to run it on a lab at home that has only 8 GB etc. total RAM.

• vCenter breaks down, what are the feature will not work?

  My vcenter goes down, I got 5 each cluster having 5 hosts in the cluster and I had configured HA and DRS and fault tolerance 5, it's never good thing work?

  Please help me to solve this problem.

  • HA will continue to work. It is configured via vCenter Server (i.e. vCenter Server configure the hosts), but it does not need vCenter Server to operate. (see the link I provide in your other thread)
  • DRS will not work. Moving the virtual machine between hosts is a vCenter server function.
  • FT will continue to work for the configured virtual machines. However, failover, no new secondary will be created.

• What will be lost if I use a new database for vCenter Server?

  Currently, we use VC 2.5 U4 with database SQL Server 2000 Personal Edition.  We intend to migrate the SQL Server used by VC to SQL Server 2005 Express 2000 database.  We have tried the upgrade on-site of the VC database but without success.

  In this way, we will create a new SQL Server 2005 Express for VC database.  We would like to see more performance statistics, the following items will be lost?

  (1) resource pool

  (2) cluster configuration

  (3) connect to the ESX host

  (4) configuration of NIC in ESX host

  (5) the allocation of resources for each virtual computer

  We are very concerned by the Network Configuration of a particular ESX host that takes us a long time to repair.

  Thank you

  The ESX host network configuration will remain as it is a host level setting.  With regard to the other elements:

  (1) Yes, you will lose your Resource Pools

  (2) your cluster configuration, including DRS rules, etc. will be lost

  (3) you will need to add each ESX host on your vCenter Server

  (4) as indicated, you will not lose your network configuration

  (5) If you set resources in a Resource Pool, then you who will lose.  If you set it on the virtual machine itself then I believe that you leave this setting.

  You will also lose some other things, like all the permissions you applied at various levels of vCenter.

• What is the latest version of vCenter Server

  Hello

  We are currently running version host with vCenter Server version 4.1.0 build-26174 ESX 4.0.0 build-345043 and vSphere Clien v4.1.0 Build-345043.

  Can someone counsel who is the latest version of vCenter server I can update?

  Concerning

  You can upgrade to level either vCenter Server 4.1 update 2 (which was released yesterday) or vCenter Server 5.0 to manage your ESX 4.0 host. With vCenter Server 5.0, are supported versions 4.x host except ESXi 4.0 U2. See http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php

• Want to take the certification VCP6-VTC, but I finished the 5.5 ESXi and vCenter Server 5.5

  Hello

  2 years ago I had the training for 5.5 ESXi and vCenter Server 5.5 - I wonder if that would satisfy the requirement and allows me to pass the exam VCP6-VTC?  Or should I stick with the VTC VCDP5 only?

  Have you taken after school.

  5.5 vSphere install, configure and manage.

  If so, please attend vSphere: what's new [5.5 to 6.0]

  It is a 2 day course that will allow you to take the exam VCP6-VTC.

  Otherwise, take VCP550 review and upgrade to VCP6-VTC in taking 2V0 - 621D.

• 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

  • 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 upgrade of our guests 5.0 ESXi and vCenter Server 5 and 5.5 Enterprise Plus

  We are the 4 upgrade hosts of ESXi 5 to 5.5

  We add 4 more guests with own ESXi 5.5 installed

  We are also upgrading our vCS 5 in the vCSA 5.5

  Using Enterprise + licenses

  Question: I'm trying to understand the best way to achieve this transition.  4 guests run about 100 virtual machines and 4 guests we add are clean slates.

  That's what I think... Please help me guys

  1. once the 4 new hosts are installed in the Datacenter clean running ESXi 5.5 I will deploy the vCSA ovf and register 4 guests with the Linux-based device.

  2. now, I have 4 new 5.5 ESXi hosts registered and running with vCSA 5.5 but I still have my old 4 guests with ESXi 5 and registered to the old vCS about 100 virtual machines running WIndows

  3. at this point I think stop on my older hosts 4 virtual machines and remove them from the vCenter Server inventory Windows and everything just their registration with the new vCSA

  4. Will be all my virtual machines or transferred with the hosts if I close them and put the hosts in maintenance mode?

  5. now, I should have all 8 guests registered with my new vCSA.  But the original 4 hosts have yet to be upgraded to ESXi 5.5

  6 move 100 virtual machines to the new 4 hosts running ESXi 5.5 and upgraded the 4 former hosts.

  7. now, I should have 8 guests with ESXi 5.5 using the vCSA

  See you soon!

  Pretty much.

  To make things easier, you can deploy the EGGS for vCSA in your current vCenter (if I remember correctly import an OVA using vCenter allows you to set certain options that should be set to the vCSA shell). After making sure that the vCSA online & configured, you can then install ESXi on all your new hosts, add them to a cluster in the vCSA and put a few trials of virtual machines on there to confirm the network setting is configured correctly. Once it's done (and assuming that the old and the new hosts use the same shared storage) you can stop the vCSA, remove it stock Windows vCS, please write it on one of your new hosts and turn on. You have now two environments (5.0 and 5.5). Next if you disconnect a host from 5.0 vCS (with virtual machines running on it), you can then connect it to the vCSA 5.5. Assuming that the vSwitchs standard networking of the exchanges that are the same name in both environments, you now can vMotion VMs between host 5.0 and 5.5 cluster. At this time, you can repeat with all remaining hosts until everything has been made the transition without service interruption. This will leave a lot of old objects in your old 5.0 vCS, but if that is getting trashed it isn't a big deal.
