iSCSI storage presented to the hosts managed by different vCenter Server - questions?

I currently have three hosts (esxi 5.0) that are managed by vcenter server 5.5 U2. The hosts are attached to iSCSI LUNS (data warehouses) 10.

I'm migrating to esxi 6.0 U2. For this, there are three new hosts have esxi 6.0 installed and managed by vcenter server 6.0 U2 U2.

The plan is to detach/remove 5.0 5.5 U2 vcenter esxi hosts. Then import it into vcenter 6.0 U2 (a new cluster will be created). Once imported, uninstall the 5.5 vcenter u2. Then turn off the resident VMs imported esxi 5 hosts and move them to 6.0 esxi hosts.

My query is regarding regarding storage.

At present, three new guests see all storage the old 5.0 esxi hosts to see (guests are not in the cluster. "I'm still trying to put things up). That's because the new hosts were deposited to the same group on the side iSCSI initiator storage. Now things, data warehouses are visible by the hosts with esxi 5.0 (managed by vcenter 5.5 u2) and also the esxi hosts 6.0 (managed by vcenter 6.0 u2). The only VMs residing in esxi environment 6 is vcenter 6.0 u2 and update manager 6.0 u2. These are in a data store that is not any other virtual machines.

That's no problem during the migration? I have not created a cluster for the esxi 6.0 hosts yet and plan to do after obtaining your entries.

Thank you!

No problem whatsoever, regardless whether if you do or that you add no vSphere 6 hosts in a HA cluster.

If you temporarily enable EVC on the vSphere hosts 6, once all hosts are connected to the same vCenter you can VMotion all VMs to new hosts even without any stop. Clear CVS once the migration is complete.

  • [HELP] SMV disappeared after restart of the host - 5.5 ESXI, Vcenter Server to the same host

    I restarted the ESXI using classic Vsphere Client. Now, all virtual machines have disappeared. I tried to connect with Vsphere Client and workstation and the list is empty. I can't access the Vcenter server since it is a virtual machine that resides in the home.

    The data store is a local disk. The data store is still there and the amount of disk space used is correct. I don't see the virtual machines in the inventory. I have re-installed ESXI 5.5, refreshed of store data and what not, there is nothing there. I am freaking out and don't know what to do.

    EDIT: I am able to navigate the data store manually by creating the new virtual machine and select the existing virtual machine following this guide but I'm not sure what is the reason for which the files would be missing or corrupt

    http://techhead.co/VMware-ESX-how-to-easily-recreate-a-missing-or-corrupt-vmx-file/

    When you browse the data store you see the virtual machine and their records?

    If you see the virtual computer files, you can open the folder, right click on the .vmx file and select Add to the inventory. who will get your VM in the inventory.

  • Problem transfer VM from one host to another, different VCenter Server ESXi

    Hello everyone.  I'm new on communities, please excuse my lack of experience of VMWare.  I have a problem with the migration of computers and I hope someone here can help you.

    We have two independent groups in my building that each have their own installer of VMWare.  They each at least two hosts ESXi, VCenter Server, san, etc.  They are in separate laboratories on separate subnets.  I need to get a system in place where some images migrated in one laboratory to another on a regular basis, but I'm running into obstacles.

    My first attempt was a copy of the right lane.  Lift the file in my store of data takes about 5 hours, and the final result is a vmdk file is not set up.  I don't know why.  I created a new VM the custom option usign and attempted to add an existing hard drive.  When I accessed this file in my data store, there is no evidence, even if a 50 GB file is really there. I also tried to install this vmdk as a second hard drive to an existing image file, and I end up with the same result.  The Add Hardware Wizard does not have the file as an option.

    My second attempt was to have a group to create a clone of the server and let it off.  Then, I tried to run an import of a clone of one VCenter Server installation to another.  This leads to an error that it was 'Impossible to determine the operating system called'.

    I also tried to import the clone in an installation of SCVMM MS I'm hungry.  That no longer works.

    We don't have a VMotion. We have Essentials more licenses.  A group is running ESXi 4.0 hosts and the other is running ESXi 4.1 hosts.  What is the best way to get an image from one group to another?

    Thank you in advance for your help!

    Joe

    You can always use tools such as Veeam Backup and replication, it will take 5 hours for the first complete copy maybe, but then it's just modified pieces which are transferred.

  • Wireless adapter is no longer present in the Device Manager

    Hello

    I have an Asus laptop 1015E (http://www.asus.com/us/Notebooks_Ultrabooks/1015E/#overview) running Windows 8.  I don't know when it happened, but the built-in wireless adapter is no longer present in the Device Manager.  I tried to use the Asus install app to reinstall the driver Asus Wireless Radio control, but it just says: it is already installed.  I also went to the site of asus via an ethernet connection and tried to download the latest drivers for wireless card, but installation cannot.  It seems as if the laptop detects most hardware, so I can't install driver software. Any ideas on how to proceed?
    Thank you

    Hi wolves.

    Do you receive an error message/code?

    When a device does not work, it's mostly because the driver has been corrupted.

    Here are some ways you can follow to resolve the problem:

    Method 1:

    Check out the link and follow the steps in the article:

    How can I troubleshoot network card?

    http://Windows.Microsoft.com/en-in/Windows-8/fix-network-adapter-problems#

    Method 2:

    You will need to install the Chipset Drivers first and later network adapter drivers.

    Reference:

    http://www.ASUS.com/us/supportonly/Drivers_For_Win8/#support_Download_36

    Method 3:

    Check the BIOS of the laptop to check that there isn't an option to toggle the map.

    Note: You can contact the manufacturer of the computer, if you are not comfortable access or make changes in the BIOS.

    Note: Changing the BIOS / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

    In addition, contact the OEM of your system and see if they can replace the adapter or run a test to make sure that the adapter is working properly.

    I hope this helps. If you have any other queries/issues related to Windows, write us and we will be happy to help you further.

  • How do I know if a host server is managed by a vcenter Server?

    I found an ESXi server in my server room, and I can connect with the root username. How will I know if this server is managed by a Vcenter server somewhere when you are connected to the host with vmware customer?

  • How to change the MOB OpenManage integration for vCenter Server registration

    A few months back, I've updated our installation of the vCenter for v2 plugin, now called OpenManage integration for vCenter Server. When you perform the upgrade, we have kept the old base done vs a new installation. During the upgrade process, we deployed the new device under a new name of the computer.

    Everything works well except that we noticed an annoying thing. Registration of the plugin is the former name of the server instead of the name of the new server-oriented. It is validated by looking at the web page MOB: http://vcenter Server/fmt drilling then down through:

    Content--> Extension Manager--> extensionList ["com.dell.plugin.OpenManage_Integration_for_VMware_vCenter"] --> server--> URL string

    The configuration of the appliamnce shows the correct new name of the device and the administration console is accessible via the new name for the device. The only place where we see the old name of the device is in the MOB config.

    We tried to remove the plugin and added, but still cannot change the value of server URL to reflect the new name of the device. Until we solve this problem, I work around the problem by keeping just the DNS entry for the old name of the server in DNS.

    Anyone know who to change the property MOB for the URL of the server?

    I solved the problem.

    I found the following article that shows how to upgrade the extension. I just cut and paste into my current values with the URL of update and now all is good.

  • Add all the storages of data presented to the host, the virtual computer's registry

    Hello

    I'm sure that it was done already - perhaps someone has a useful script that they could share?

    I have a few instant volumes presented to an ESXi host, I want a script that will automatically appoint those and add them to the host. It could be a volume - it's maybe ten. I understand the mapping of storage to the host OK unit, but I have a problem with VMware. There is a chance that these data stores could be seen by the original host - so I have to will them.

    Once data warehouses are mounted, I want to find two machines in data warehouses and enter them in vCenter.

    Someone at - it something that they could share?

    Thank you very much!

    Do you get any error messages?

    It does not work?

  • Move a virtual machine from one host to another without vCenter Server

    Hi all

    Something's been recently who raised the question on moving a virtual machine between hosts without vCenter.  I am running vSphere manage 3 blades in a c3000.  I have a shared storage iSCSI blade which all the blades connect to.  All of my virtual machines are in the same data store on the shared storage.  I'm also under vCenter Server as a virtual machine on one of the blades.  The blade that hosts the vCenter Server VM dead recently. What I was hoping to do is use vSphere Client to connect directly to one of the other blades and hover over the vCenter Server VM to one of the blades of the good, but I can't find a way to do this.  Using the browser of data store and see all of the virtual machine on the store of data without problem, but I see no way to migrate the virtual machine without vCenter server.  In the end, the blade has only had a problem of memory I corrected and managed to raise the blade but I now think of the future.  I use only Essentials, so I don't have access to vMotion and Storage vMotion.  I know that running vCenter Server is supported by Vmware, but I wonder if it's the best practices.

    Any thoughts?

    Hi, I assume that you get this error because the machine is running, try to connect directly to the host and do the same with an engine off the machine.

  • Activate the VCA Mode of VMware vCenter Server Appliance

    Hello

    I'm pretty new on vSphere.  I have two hosts running esxi 5.1 what one of these hosts running the "VMware vCenter Server Appliance' with vSphere version 5.5.  I currently have a single cluster containing all the VMS as well hosts and the SAN.

    I try to activate the EVC mode, but when I try it tells me that the host is not allowed because there are powered on virtual machines.  I can turn off all the virtual machines except the vCenter device and I still get the problem on the host that has the device on it.  If I turn off the unit, I can't use vSphere to activate CVS.

    How can I activate CVS when vSphere does not work?

    Thank you

    Jeff

    Hi Welcome to the communities,

    This one is a bit complicated

    You have:

    1. turn off all VMs on Host1 (while vCenter device is on Host2)

    2 bring Host1 on Cluster, select CVS clustered.

    3. put all the virtual machines on Host2 (also vCenter device)

    4. connect on Host2 directly to vSphere Client Windows

    5. remove the vCenter inventory unit

    6. connect on Host1 directly to vSphere Client Windows

    7. the data store when the appliance and add it to the inventory of research. Power on

    8. connect the device with Web client or vSphere vCenter

    9. move the second host in the cluster

    And you're done

  • Lab Manager 3 and vCenter Server 4?

    Lab Manager 3.0.2 will work if I upgrade Virtual Center to version 4?  (I realize ESX 4 is not supported, was impossible to find out what anyone simply upgrading to vCenter Server.)

    Right now I have 2 groups managed by a server vCenter Server, a 'production' and another for Lab Manager.  If I upgrade my production cluster to vSphere, can I maintain a separate vCenter server with the old version to support Lab Manager?

  • ESX host with local storage recommended for the host partition table?

    Pre-configured

    However with a system with local storage would you set it up the same way, and whatever it is must be amended to change to get ESX to write log files to the different partitions?  I would like to configure it for future expansion for when the enterprise package is configured.

    Yes, I would set up the same way with an ESX with local storage server and nothing needs to be changed for the vmekernel right at the partition/var - unless of course you want to write to a log server that you need to change a configuration file to point to the server logs.  If you talk to the ESX Enterprise license you willnot have to change partiition table-

    Also on something else if you don't have a SAN/NAS storage you will also need to create a VMFS partition on the local data store to host your virtual machines
