Management of vSphere vCenter crash recovery

hardware server vCenter failed and two vSphere server are always associated with this server.  You want to disassociate the two servers with the old VirtualCenter and establish a new connection with the new vCenter server.

Environment:

5.1 ESXi server (production)

4.1 ESX Server (production)

Server device (not longer exists / dead) vcenter 5.1 running on separate 5.1 ESXi Server

Scenario:

5.1 vCenter server to manage both production above vSphere servers.  The material which housed the vCenter server has failed and is unrecoverable.  Both servers are accessible through the vSphere client.

The ESX 4.1 Server I get the text next message when you use the vSphere client: "this host is currently managed by the vCenter Server Server with the address IP X.X.X.X. changes to this host this session can now be reflected in sessions clients vSphere watching the vCenter Server.»  The management host, under the summary poster tab: "this host is currently managed by vCenter Server X.X.X.X..

The ESXi server 5.1 has received the same message when you use the vSphere client until I chose an option under host of disassociate or disconnect with the vCenter Server Management (don't remember exactly what was the option).  It succeeded, to some extent.  When you connect to the server ESXi 5.1, it does not present the message indicated with the ESX 4.1 server.

A different vCenter server has been installed in an attempt to restore a centralized without success.  Adding a server as a host to the data center generates the following error message: "failed to contact the specified host (serveur7). "The host may not be available on the network, is maybe a problem of network configuration or management on this host services may not respond.

Objective:

To dissociate the two servers with the old VirtualCenter and establish a new connection with the new vCenter server.

Any help would be appreciated.

Thank you.

Can you confirm the new vCenter Server is properly registered in DNS and is able to resolve the names of domain the ESXi host's FULL name, i.e. settings of IP of the server vCenter, including its server DNS entry are correct? Are you able to connect hosts using their IP addresses, just to test if it works.

  • How to remotely manage the Vsphere VCenter?

    I have a practical lab for vSphere configuration and a VC to manage my vsphere hosts. I wanted to know what are the ports should I open on my network if I want to use vSphere Client to connect to VC outside my network.

    Thank you.

    R@DHO

    If you kept the default ports, then they need to do:

    80, 443, 902 (UDP), 8080 and 8443.

    You can also get a list of ports from: http://www.latogalabs.com/vmw-launchpad/vmware-network-port-list/

  • Managing 2 vsphere vcenter servers

    We have 2 each Vcenter server running data centers.  (Principal and Dr. Colo data center).  In Vcenter 4, we had our configured client vsphere where we could both stop VCenter VShpere inside servers.   I could log into my main data center and the VCenter servers were visible and manageable.  (Even with our Colo).  Somehow during our migration up to 5 VCenter, we lost that connection.

    I would like to pick it up where I can see them both again.

  • VSphere of site Recovery Manager support

    Hi all

    We currently host two farms of ESX 3.5 Upd.3 in one of our company's website, and we intend to build a new and more powerful vSphere 4 based firm. Finally, we will upgrade two old farms for the new product, too.

    At the end we you will also need to activate two of our farms to resume with the company a remote site (at a given time that this need will become two-way).

    That is why we are trying to understand if the VMware vCenter Site Recovery Manager is produced following our needs or not.

    Unfortunately, it seems that the vCenter SRM is not yet able to manage a farm of vSphere 4: does anyone know precisely what to be sure of the release date for the new version of SRM (active vSphere)?

    And also, I am wrong in suspecting that the fact that the full name of the SRM includes a reference to vCenter (vCenter SRM) may suggest that an upgrade of our current Virtual Center 2.5 Upd. 3 to the most recent version of the vCenter server would be by the force required to install and use the SRM product even against a battery of ESX 3.5 based servers?

    Thank you very much for your help.

    Best regards

    Salvatore

    Salvatore,

    We shared that SRM will be compatible with vSphere 4 before the end of the year and preview of vSphere 4 + feature SRM at VMworld in San Francisco this month.  We have not yet made a public announcement on a more precise date, but stay tuned.

    The currently available version of SRM (SRM 1.0 U1) is compatible with vCenter Server 2.5 - you can see the details in the http://www.vmware.com/support/pubs/srm_pubs.htmlcompatibility document.  For what it's worth, 'vCenter' is a family name of products for our management of the add-on products (e.g. vCenter AppSpeed, vCenter Lifecycle Manager, vCenter Lab Manager, etc.).  The product formerly VirtualCenter is now called "vCenter Server.

    Once SRM is compatible with vSphere 4, you should not use vCenter Server 4 can use SRM with vSphere 4 servers because vCenter Server 2.5 is not compatible with vSphere 4.

    Hope that helps,

    Jon

    While I can't give you a solution, I can share that I had a similar problem with an SRM installation.  Like yours, mine was a working facility which, for some strange reason, began to exhibit the same symptoms.  Start the service, in a second or two, stopped service.

    I opened a ticket with VMware on the issue and in more than three months of back and fourth Exchange with various Tech support I have ever received a satisfactory answer on what caused it.  The 'solution' they gave me was to remove the database SQL RS and re - install SRM.  This 'solution' has worked, but if this question comes up, I'll probably have to back unpleasant, emphasizing the fact that they solve the problem.

    I wish I could be more help, but that's it.  I feel your pain.

  • What management software is free with ESXi 4.0?  (re: vSphere, vCenter, etc.)

    I'm new and VMware ESXi, but I'm learning and I'd like to better understand the different management products available.

    I installed the free ESXi 4.0, so what software is available?  (free)

    (1) I can't download "vSphere Client" directly from my ESXi host.  Is this different than 'vSphere' from the VMware Web site?

    (2) what is the difference between vSphere and vSphere Remote Command Line Client?

    (3) I have free access to vSphere vCenter?  This is only used to manage multiple ESXi hosts at the same time?

    Thanks much for any help!

    One of the most interesting free tools from VMware is in my view VMware vSphere PowerCLI.

    vSphere 4 is a suite of products. vSphere client is a product of this suite.

    The host update is a utility that allows you to upgrade a vSphere (ESX or ESXi server) from one version to the other host. You don't need this if you start with the last update of the ESXi 4.0 version 2.

  • 'Disconnect' a managed host to vCenter Server: practical application?

    The vSphere client offers the possibility to "unplug" a managed host to vCenter Server (right-click > disconnect).

    I was wondering in what situations it would be used/useful? He influence the virtual machines running on the host? Is "reconnect" everything just like linking to the departure to a new host?

    mudage

    Here is what I use the button disconnect to:

    I have an old vCenter 4 install with 10 ESXi 4.0 hosts, I now build a vCenter 5.5 system and need to migrate to this vCenter but I can't have all the time.

    So, I hit the button disconnect and then add the ESXi 4.0 host in my new vCenter, then at my convenience I then host 4.0 on a host 5.5 vmotion.

    I hope this makes sense to you.

  • Site Recovery Manager is certified for the recovery of the database?

    Hi all

    I is currently exploring the possibility of using the Site Recovery Manager for database DR scenarios.

    Before you go more away and actually try to run some scenarios, I'd be interested if someone of you has tried to do the same thing and if you actually managed to go beyond the situation of disaster, i.e. with primary VM [stop] down, then activating the VM DR.

    Another important aspect, I would be interested is the certification: the Site Recovery Manager is certified for the recovery of the VMS running databases?

    And if so, what data is it certified by: Oracle 10/11, SQL Server 2005/2008, DB2 9.x, etc.?

    If the answers are well known to my question, please just point me to the right source by a link - that should be enough.

    Thank you

    At EMC, we use this definition (which is fairly common):

    Uniform crash means that all devices in a given consistency group are writing order in line at a point in time.  If an application can recover from an accident, such as would be seen with a power failure or any other event of failure, then the application can recover from failover.

  • How to make backups without vSphere/vCenter

    We are one of the companies at low prices that only use ESX, cannot get them to buy me vSphere/vCenter again.

    Not much, we have only 8 physical hosts, so I can manage it with the vSphere Client a host at a time.

    Is there a smart way to make level vm backups in my situation?  I can export OVFs manually, or copy the files from the virtual machine to a store in offline mode, but these two need to cull the virtual machine. (you cannot copy or move a machine virtual everything in its place)

    Is there a way (with vCLI or powerCLI) to maybe make a snapshot, move the snapshot offline, and then delete the original... or something like that?

    I'm really just looking for a smart way to make level vm backups that don't require bringning to the bottom of the virtual machine, and that perhaps I could automate with a script so its more of a real-time continuous data protection.

  • vSphere/vCenter client and web services

    Hello

    Don't vSphere client (or client to vCenter earlier) invoke web services of vSphere internally to perform operations on the ESX Server?

    I'm new to VMware developemnt.

    As I understand it, it's the client vSphere or vCenter is a management console. An actioan/operations such as create VMS or cloning images actually occur on the ESX servers or hosts. Web services are hosted on the ESX servers. When we perform an action via client vSphere/vCenter (e.g. create the VM), internally, it would be invoking appropriate API provided by the web service SDKto do you need.

    My understanding is correct?

    If you connect to vCenter or ESX host (i) themselves by using the Client vSphere, the majority of applications using vSphere API... I say majority because I do not know there are undocumented more that VMware uses behind the scenes, but in general, it is true. If you perform an operation in vCenter and it applies to a host, vCenter will communicate this request to the host.

    If you're new to QALY/SDK: you can spend the time to enter the section "Learning" of the developer forums, there is lots of useful information here: http://communities.vmware.com/community/developer/learn

    Here's a great doc Getting Started with vSphere SDK - Update for SDK 4.1 release that has a lot of information/explanations on how it all works, you should spend time passing on it and then ask questions in the appropriate follow-up, if you need more detailed explanation.

  • vCenter data recovery - is it upgrade for VCB

    Hello

    I wonder if vCenter data recovery is an upgrade for existing ESX enterprise clients using VCB, or it is a new product which must be purchased?

    any ideas?

    VMware data recovery is intended as a product recovery and backup of disk to disk for virtual machines.

    The product is included in some editions of vSphere and downloadable and add-on for some of the other (for example standard).

    hope that helps,
