May 4 ESX and ESXi 4.1 exist in the same Cluster?

Hello all-

Installation program:

vSphere 4.0 Infrastructure

  • CLUSTER1 = 2 ESX 4.0 hosts (Enterprise license) (HA/DRS)

  • Networking is standard vSwitches

  • Storage is Compellent SAN Fiber Channel

  • About 20 mV

  • 2 = 2 ESX 4.0 hosts (EnterprisePlus licenses) cluster (HA/DRS)

  • Networking is Cisco Nexus 1000v Distributed Virtual Switch

  • Storage is Compellent SAN Fiber Channel

  • About 15 virtual machines

The question is this:

How can I upgrade correctly these four hosts 4 ESX to ESXi 4.1 with very little or no interruption of service?   Yet once ESX 4 & gt; ESXi 4.1

Notes:

  • Assume that I already have vCenter Server 4.1 installed on Windows Server 2008 R2 with a compatible SQL database.

More information?  I can provide.  Can I just disable HA/DRS, upgrade to a host at a time and then add it to the respective cluster and configure?  What difficulties will be the Nexus switch vDS cause?

Yes, the exception would you use FT - http://kb.vmware.com/kb/1013637.

  • Is it possible to use GPFS or another build is a SAN storage shared for multiple ESX and ESXi hosts?

    We have a license GPFS and SAN storage. I am trying to create a storage shared for multiple ESX and ESXi hosts share existing virtual machines. We tried once NFS, it of a little slow and consume too much bandwidth LAN.

    Anyone can help answer? Thank you very much in advance!

    It depends on your storage space.

    You must connect all hosts to the same San, then follow the configuration guide of ESXi and specific documentation for your storage space (for sharing LUNS on multiple hosts).

  • Differences between ESX and ESXi

    Hai,

    As I am new to VI environment I doubt that where features ESX and ESXi are different, it may be stupid but can help me a lot.

    Hello

    Please check the link to the differences between ESX and ESXi below.

    http://www.VMware.com/products/vSphere/ESXi-and-ESX/compare.html

    Please note ESX is present in version 3.x, 4.x. starting vsphere 5.0, we have only ESXi.

    ESXi doesnot have a service console and has the smallest footprint of 70 MB and so is safer and more reliable, because it has a smaller surface set.

    Please allow points if you find the article useful.

    Thank you

  • Store of data sharing between 4 ESX and ESXi 5

    Hello

    I have a vSphere environment 4.1 with a vCenter and a cluster of 3 ESX 4.1 access to the content of data through fiberchanel (type scneario) warehouses.

    And now I need to install a new ESXi 5.x (cannot be a different version) in a separate environment, outside of the current vCenter, BUT to access the warehouses of data even as the cluster of vSphere 4 current.

    Anyone know if there should be no problem sharing between 4 ESX and ESXi 5 access to the same data storage?

    Thanks in advance

    As long as the FC zoning is configured properly, avoid all the problems.   ESXi 5 will be able to see the data created by ESX4 VMFS3 stores, it will not be able to create the same size of virtual machine he can on a 5 VMFS datastore.

  • Need a powercli script to create a new account a local administrator on all ESX and ESXi hosts in the vcenter

    Hi all

    If someone can help me with a powercli script to create a new account a local administrator on all ESX and ESXi hosts in the vcenter, create a role called admin and give all access except the root. This shoulb be past by a virtual centre.

    Very much appreciated to help him.

    Kind regards

    MelLvin

    I suspect that you posted your question to the wrong thread

    This requires only a minor change to the script above actually.

    Something like that

    $groupName = "group"$accountName = "user"$accountPswd = "password"$accountDescription = "A user"
    
    $esxlist = Get-VMHostforeach($esx in $esxlist){    Connect-VIServer -Server $esx -User root -Password "password"
    
        Try {      Get-VMHostAccount -Id $groupName -Group -ErrorAction Stop | Out-Null    }    Catch {      New-VMHostAccount -Id $groupName -GroupAccount | Out-Null    }
    
        $rootFolder = Get-Folder -Name ha-folder-root    Try{        $account = Get-VMHostAccount -Id $accountName -ErrorAction Stop |        Set-VMHostAccount -Password $accountPswd -Description $accountDescription -AssignGroups $groupName    }    Catch{        $account = New-VMHostAccount -Id $accountName -Password $accountPswd -Description $accountDescription -UserAccount -GrantShellAccess -AssignGroups $groupName    }
    
        $rootFolder = Get-Folder -Name ha-folder-root    New-VIPermission -Entity $rootFolder -Principal $account -Role admin
    
        Disconnect-VIServer -Confirm:$false}
    
  • Script - missing and hotfixes installed for ESX and ESXi

    Can I have the script i.e. missing and hotfixes installed for ESX and ESXi using the CLI power only? out put should be csv format

    You reset the content of the table $Results on each iteration of the baseline.

    Try like this

    $Results = @()
    foreach($esx in Get-VMHost) {
      foreach($baseline in (Get-Compliance -Entity $esx -Detailed | where {$_.Status -eq "NotCompliant"})){
        $Results += $baseline.CompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"Compliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
    
        $Results += $baseline.NotCompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"NotCompliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
      }
    }
    $Results
    

    It will give the installed and lack of patches which are defined in the non-compliant baslines related to the ESXi host.

    If you want to see all the lines, also the most consistent, omit the Where clause on the base line (foreach) loop.

  • ESX and ESXi

    What are the fundamental differences between ESX and ESXi. Someone could it say please interview point of view. Just need about 4 to 5 differences.

    Thank you

    Prashant

    The difference between ESX and ESXi, ESX was the classic version with a dedicated Service console embarked with him, however, ESXi is the version of Vsphere without the Console service. Because ESXi is without the service console, so its size is very small and its called summer have footprint small disc. With the release of VSphere VMware 5.0 and later versions has deprecated the classic ESX version there is therefore no now unavailable ESX and we only ESXi now.

  • DRS cluster: You can mix 4.1 ESX and ESXi 4.1?

    Not very complext, but we have a DRS cluster of 8 hosts x 3850 of IBM on ESX 4.1 and we will upgrade them both to ESXi 4.1 update 1.  There will be questions mixing a cluster of ESX and ESXi servers?

    Yes, 100% supported!  both are the same hypervisor, so you should have no problem running in the same cluster.  After all it is the best way to do a upgrade spread, and how we made our move between ESX and ESXi.

  • VMotion with ESX and ESXi in the same cluster.

    My client wants to spend his whole army ESX 4.0 to ESXi 4.1 host. I know that it requires a clean install of the host. But vMotion always works in a cluster with a mix of the host ESX 4.0 and ESXi 4.1?

    You will be fine to have a mixed group of ESX and ESXi hosts.

  • Is it possible to run Windows 7 * 32-bit and Windows 7 * 64-bit on the same computer?

    I have Windows 7 * 32 bit running in my computer. But a lot of games that is built on 64-bit do not work in my system. I tried to install Windows 7 * 64 Bit on another partition of my computer. But before the start of the system using the Windows 7 installation DVD, I get an error with the oxc00000e9 status. The info says: unexpected i/o error has occurred.

    My question is whether it can run Windows 7 * 32-bit and Windows 7 * 64-bit on the same computer. If so, how to install the Windows 7 * 64-Bit? Thank you.

    Yes, you can, but you will need to have a permit for it if you plan to have both on the same computer.

    the key that can be used with 32-bit or 64-bit Windows 7 is designed to drive 1. You cannot use install both. 1 license, 1 installation, so choose wisely. If you want to install Windows 7 32 or 64 bit on another partition or another computer, you must purchase an additional license.

    INSTALLATION AND USE RIGHTS.

    a. one copy per computer. You can install one copy of the software on a single computer. This computer is "licensed computer.

    b. a computer license. You can use the software on up to two processors of the computer under license at some point. Except as provided in these license terms, you cannot use the software on any other computer.

    c. number of users. Except as provided in these license terms, only one user may use the software at a time.

    d. other Versions. The software may include several versions, such as 32-bit and 64-bit. You may install and use only one version at a time.

  • Transaction and transaction AppModule Taskflow both are the same or not?

    Transaction and transaction AppModule Taskflow both are the same or not? or what are the differences between these two operations.

    Workflow transaction is different from the transaction data base (I mean the transaction returned by am.getDBTransaction ()). Each workflow is associated with a data control framework. A data control framework is the container that is associated with a workflow that contains several instances of data control. The ADF Model layer exposes the DataControlFrame interface to manage a transaction involving data controls in the framework. DataControlFrame interface exposes methods such as:

    • beginTransaction()
    • Commit()
    • Rollback()
    • createSavepoint () - Note that it is the backup point maintained by the controller of Oracle ADF and it is similar to the point of backup of database
    • isTransactionDirty()

    Task Transaction flow

    There are four transaction options that a stubborn workflow can use (notice that unbounded flow task does not support transactions):

    1. No Transaction controller: delimited task called flow does not participate in the management of transactions any controller ADF.
    2. Always Begin new Transaction: A new transaction begins when the stubborn workflow is entered, regardless of whether a transaction is in progress. The new transaction ends when the stubborn workflow stops.
    3. Always Use Existing Transaction: When it is called, the stubborn workflow participate in an existing transaction already underway.
    4. Use the existing if Possible Transaction: when it is called, the stubborn workflow is involved either in an existing transaction if there is, or starts a new transaction when the entrance to the stubborn workflow, if one does not exist.
  • These two types of schema cache can co-exist for the same application?

    From what you describe, that you're on track.

    I think that you have a number of servers that have a size limit near cache and stored disabled for distributed share. Then you have a number of servers that are responsible for the part of writeback (active storage) distributed.
