Mix of ESX 3.5 and VMware ESX in the same cluster

Hello

I'm currently involved in ESX 3.5 Migrating virtual machines to a new vSphere environment.  All ESX 3.5 hosts running on obsolete kit and will be decomm had at the end of the project.  All hosts are managed by the same server vCenter.

The only problem is, I have to add an additional ESX4 server, but there is not enough available physical switch ports.  I have decomm one ESX3.5 servers in order to free ports, but they run at 2 knots, and I will lose redundancy if a hardware problem arises.

My proposed Solution: -.

I think decomming ESX3.5 host 1 and move it to the new vSphere cluster.  The type of brand/model/CPU is different between the old and the new servers and I am not concerned by VMs DRS'ing between 2 environments, however, I understand that I have would be protected by HA if anything disastrous happened.  All hosts are connected to the same storage.

You don't see any problem with that?

You can have a mixed cluster, but this must be managed by vCenter 4.x.

And you also need a license for the former hosts of 3.x server.

HA will work.

If the CPU is compatible VCA, then as VMotion, DRS, VCA will work.

  • Impossible to use VMWare Server and Virtual PC at the same time?

    I have a Win 7 box I use VirtualPC (unfortunately, VPN to the employer only supports the 32-bit Win XP).

    If I try to start any virtual machines using VMWare Server, power on and then immediately off.  Tried several different VMs.

    However, if I disable VirtualPC, they all work normally.

    Then... there at - it a known issue with the help of Virtual PC and VMWare Server at the same time?

    BTW, I didn't see this problem when you use Virtual PC and VMWare Player at the same time.

    VirtualPC leaves the CPU of the exploitation of VMX root, which is a restricted mode.  VMware Server is problems to switch between legacy mode and long (this switch is prohibited when the CPU is in VMX root operation).  The current versions of the workstation and the player are able to circumvent this restriction.

  • VMware and rdesktop ubuntu has the same full screen shortcut keys

    Hello

    I use vmware to run ubuntu 10.04. I installed vmware player 3.1.

    I use rdesktop in ubuntu to access my other machine with windows xp installed.

    rdesktop uses 'enter ctrlalt'as a shortcut to turn off the mode or full-screen. Unfortunately vmware also uses the same combination of keys as a shortcut to toggle the mode full-screen for the vmware window.

    So, if I start fullscreen rdesktop and try to get back to full screen using the shortcut "ctrlaltenter", vmware starts to switch between mode full screen. And only remaining vestige of the way is to restart vmware to review the ubuntu desktop.

    Hope you understand my problem. Is there a way I can disable 'ctrlaltDELETE' in vmware? I couldn't find any other alternative key combination for rdesktop exit full-screen.

    Thank you

    Hi harsh,

    Welcome to the forums.

    It seems possible to change the default shortcut via the configuration file of "preferences". Take a look at this thread for more details.

    It will be useful.

  • IS the UUID and device ID is the same?

    Dear team,

    Ask you to help me with the following queries?

    Q1:-UUID and device Id is the same?

    Q2:-peripheral Id comes from storage array to a LUN?

    Q3:-is the UUID provided by an ESX Server, then this ESX Server to identify this LUN?

    Q4 :-UUID is also called or refers signature ESX?

    Concerning

    Mr. VMware.

    Hello

    in general, the signature should not change in a scenario you desrcibed.

    The ESX host allows you to create a data store VMFS on this LUN collects information provided by the table.

    This information will be used to generate a signature (the process itself is still not published by VMware).

    The signature itself is stored in the VMFS data store and is always used when the Renumeriser SCSI operations.

    Whenever an ESX Server perform a reboot or rescan operation, the following procedure will be used (high level).

    The ESX Server will

    • analyze the SCSI bus and collects information for SCSI on any device seen
    • Search for an existing partition table and the types of known partitions
    • for each VMFS data store found it will read the signature
    • checks if the signature matches with SCSI information
      • matches, continue to accumulate the VMFS datastore
      • does not, this VMFS datastore is not mounted automatically because it is identified as an "instant" feature

    So you could access easily other ESX servers on this device when each ESX Server does not see the device with the same SCSI information.

    As a best practice, each server ESX shoud see such device shared with the same LUN ID.

    The modern paintings are capable of presenting storage devices with different LUN ID in an initiator (HBA) basis.

    Another thing to keep in mind that ports in frontend used table use the same Port SCSI/flag settings, but these indicators may differ between vendors.

    If these two basic requirements are met, you will be able to share the easy storage device between multiple ESX servers.

    Kind regards

  • The s/w and h/w on the same host iSCSI initiators.

    Hello

    Can someone tell me if both software and hardware on the same host iSCSI initiators and looking the same LUN is supported in ESX3.5U5, 4.0U2 and 4.1.

    If this isn't the case, please give me the URL of any article of vmware goes in the same.

    Thank you

    P Martin

    The closest would be on page 28 of the 4.1 "iSCSI SAN slot Guide.

    http://www.VMware.com/PDF/vSphere4/R41/vsp_41_iscsi_san_cfg.PDF

    Because the software initiator ESX is definitely a charge adapter, this could be considered to be applicable.

    In spite of being is not clearly established, there is no summer tested enough to be considered as support even if there are no known issues.

  • Is possible let activate domain multi UCS VM - FEX and sign up for the same vCenter

    Hi Experts,

    We have 7 domain UCS. But only a vCenter. Now, we want to enable VM - FEX on each UCS area and sign up for the same vCenter. Is - it work? I have found no description limit configuration on this relationship.

    Or we create 7 vCenter for each UCS area? (But I think it's not sense.)

    Best regards
    Meng-Yuan Hsieh (Nick)

    Hi Moua!

    I open a TAC case on that, and after that many discussions with Cisco, connecting several areas a single vCenter UCS is supported.  However, it turns out that Cisco failed to document this and how to make it work.  You will find that the procedures were written in old documentation for VN-LINK and others for VM - FEX.  This documentation shows that it is necessary to create new certificates, and it must match the key to expansion.  This is NOT true nor with the new versions of UCSM and vCenter.  Cisco, said they will update their documentation.

    Here are the steps that we took to connect two UCS areas for the same vCenter using default self-signed certificates.  I hope this helps...  Please mark this message as the right answer when you get a chance.  Thank you!!

    vCenter Version: 5.5

    UCSM Version: 2.2(5a)

    1. On the VM in UCS Manager tab, click VMware.
    2. Set up a key of the unique extension for every area of UCS.
    3. Click on "Configure VMware integration" on each area of UCS and export expansion of local storage.
    4. Install each UCS domain extensions in vCenter.
    5. After you install the extensions, back to UCSM and click Next where you left off in configure integration with VMware
    6. Run the wizard and after that it's over, areas of the UCS should now be connected to the vCenter.

  • Is it possible to transfer everything to a virtual hard disk that is smaller on a virtual hard disk that is larger in VMWare Workstation, using the same virtual machine?

    Hello

    I was wondering if it is possible to transfer everything to a virtual hard disk that is smaller on a virtual hard disk that is larger in VMWare Workstation, using the same virtual machine? In the affirmative, please could someone advise me on how to do it. Also utility management and disk transfer can be used in virtual machines to do this?

    Thank you very much

    Tim Auluck

    I'm not sure what exactly you are asking. Can you please clarify!

    Basically you can resize a virtual drive or add a second virtual disk to a virtual machine and transfer/copy files. You can also resize the virtual disk using VMware Converter for example.

  • Can you have v4.1 and v3.5 hosts in the same cluster?

    Can you have v4.1 and v3.5 hosts in the same cluster?  Before that I have to try, I thought I would check.  It would be only temporary until all hosts are upgraded.

    > Yes, 3.5 and 4.1 can coexist.

    But they can be managed vcenter 4.1 only, and you must leave the old license server for 3.5 hosts.
