Cold migration

• "Cold migration" use vMotion enabled network?

  I have three installed ESXi hosts and they are networked with 2 different networks. One is the regular 100mbps network which I use as management network, which is also used to connect my client to connect to guests individually vsphere or vCenter Server (running under VM on one of the hosts).

  My other is network of 1 Gbit/s which I am trying to qualify vMotion only for traffic. I activated vMotion (pronounced check) on the vmKernel port which is connected to the gigabit speed network while I disabled the vMotion on the slower network.

  Yet, to my surprise, when I do 'MIGRATION' COLD (focus is on migration to cold, not hot vMotion), he always uses the slower network while the faster network remains inactive.

  This seems to show that the path taken by Migration cold network is unrelated to the one taken by active vMotion vmKernel port. How can I make sure that cold migration and other activities 'Lourdes' happens ONLY through the network more fast.

  I want to only use the slower network which is on my LAN to connect (on my laptop) Client vsphere vCenter Server or host directly if necessary. Can someone please? I like you a lot because I'm stuck now. Thank you.

  Migration cold work through Console of Service / Management VMkernel and don't use VMotion VMkernel.

• How cold migration transfer VMDK file on which network indeed?

  There is an explanation, that I got from this community is cold migration transfer on service console network, the specific "service console" connects the VI client.  But this explanation cannot explain this situation below.

  Virtual Center: 138.35.170.87 (gateway: 138.35.170.1)

  ESX1: 15.171.70.10 (gateway: 15.171.70.1)

  ESX2: 15.171.70.11 (gateway: 15.171.70.1)

  ESX1 and ESX2 is under HA environment, linking SAN even with a disk of EVA storage array.

  15 171,70. * can access 138.35.170 * between them freely by the window / door entry

  15.171.70 * is the network isolation. They cannot access each other.

  Migration cold can work well in the environment.

  The vdisk to the virtual machine, we planned to migrate is dedicate to the logical unit number, and the target data store is dedicated lun as well.

  Could you tell me how cold migration works?

  Cold migration can be of different types:

  1 Datastore1-> Datastore2, ESX remains the same: copy of files only.

  2 Datastore1-> Datastore2, ESX1-> ESX2, and data warehouses are not shared: via the Service Console / VMkernel.

  3 Datastore1-> Datastore2, ESX1-> ESX2, and data warehouses are shared: I guess than filecopy and re-enter on an another ESX VM.

• Cold migration of MSCS cluster node clients?

  Work on the establishment of a MSCS cluster on 2 hosts.  The hosts are the ESXi 5.5 build 1892794.

  My shared disks are RDM compatibility mode physical that I have attached to a second SCSI controller in physical sharing mode.

  My cluster validation wizard is successfully completed.

  However, if I turn off the guests, everyone migrate to a different host (with FC to the RDM LUN connectivity), turn on and then run the cluster validation Wizard error e/s disk wizard reports on tests of arbitration and failover.

  I learned that when I see these mistakes I can unsubscribe the VMs, detach the storage from the host, restart the host, attached storage, re - save virtual machines, and then validation is successful.  However, it is a bit complicated and if I say lose a blade and need to put one of my guests node elsewhere, I want to do without the time and hassle.  Is this possible?

  I know vMotion is not supported with the physical bus sharing, but this ban applies to cold (power off) so migration?  Or is this an indication that I screwed up my configuration?

  Any thoughts would be great.

  Thank you

  Here's what VMware has sent:

  =======================

  -A virtual machine that has a ROW in a MSCS cluster connected in physical compatibility mode cannot be vMotioned.

  -Even if you do a cold vMotion (stop the virtual computer, then vMotion), the ROW could be detected as vmdk and you may need to remove
  She and present it back or re - enter as you mentioned.

  -Best practices recommend Vmware are that - before the migration, remove the ROW of the virtual machine, and then migrate the virtual machine. Once the
  VM was vMotion, then you can attach the RDM to the virtual machine.

  Unfortunately there is no work around on this
  scenario.

  ======================================

  So I guess the cold, you can migrate the MSCS cluster nodes but sometimes it does not work quite as well and so its best to remove the ROW before migration cold.

  Thanks to all who have posted!

• Several cold migration via PowerCLI on data centers

  Hi all

  Here's my problem.   I am trying to automate migration cold of the about 30 mV (obviously power off) of a data center to another in the same virtual Center.    I was able to migrate both through PowerCLI 1 VM by using the following script.  I used Onyx to help me with the basis for the script.

  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec

  $spec.datastore = New-Object VMware.Vim.ManagedObjectReference

  $spec.datastore.type = 'Datastore '.

  $spec.datastore.value = "datastore-1672.

  $spec.pool = New-Object VMware.Vim.ManagedObjectReference

  $spec.pool.type = 'ResourcePool.

  $spec.pool.value = 'resgroup-4017.

  $spec.host = New-Object VMware.Vim.ManagedObjectReference

  $spec.host.type = 'HostSystem.

  $spec.host.value = 'host-4018.

  $spec.disk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator [] (1)

  $spec.disk [0] = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator

  $spec.disk [0] .diskId = 2000

  $spec.disk [0] .datastore = New-Object VMware.Vim.ManagedObjectReference

  $spec.disk [0].datastore.type = "data store".

  $spec.disk [0].datastore.value = "datastore-1672.

  _this $ = Get-view -Id ' VirtualMachine-vm-4029'. "

  _this $. RelocateVM_Task ($spec, "defaultPriority")

  What I'm trying to do now, is to use variables for the values of the data store, pool, host and Get-View to the virtual machine itself to run a migration of more than 1 at a time.  So here's what I tried to do

  to connect-viserver VCENTERSERVER.domain.local

  $vms = Import-CSV "G:\temp\scripts\relocate.csv".

  {foreach ($vm to $vms)

  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec

  $spec.datastore = New-Object VMware.Vim.ManagedObjectReference

  $spec.datastore.type = 'Datastore '.

  $spec.datastore.value = $vm. DatastoreName

  $spec.pool = New-Object VMware.Vim.ManagedObjectReference

  $spec.pool.type = 'ResourcePool.

  $spec.pool.value = $vm. ResourcePoolName

  $spec.host = New-Object VMware.Vim.ManagedObjectReference

  $spec.host.type = 'HostSystem.

  $spec.host.value = $vm. ESXHostName

  $spec.disk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator [] (1)

  $spec.disk [0] = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator

  $spec.disk [0] .diskId = 2000

  $spec.disk [0] .datastore = New-Object VMware.Vim.ManagedObjectReference

  $spec.disk [0].datastore.type = "data store".

  $spec.disk [0].datastore.value = $vm. DatastoreName

  _this $ = Get-view -Id $vm. Name

  _this $. RelocateVM_Task ($spec, "defaultPriority")

  }

  Here's what my CSV file looks like.  I used PowerCLI for find the real ID for each object.

  Name, DatastoreName, ResourcePoolName, ESXHostName

  VirtualMachine-vm-4029,datastore-4557,resgroup-3694,HostSystem-host-3729

  VirtualMachine-vm-4030,datastore-4558,resgroup-3694,HostSystem-host-3731

  Here is the error message I receive when you run the script

  Exception by calling 'RelocateVM_Task' with '2' or the arguments: "the object has already been deleted or was not completely created.

  G:\temp\scripts\RelocateMOD.ps1:25 char: 23

  + $_C. RelocateVM_Task < < < < ($spec, "defaultPriority")

  + CategoryInfo: NotSpecified: (:)) [], MethodInvocationException)

  Exception by calling 'RelocateVM_Task' with '2' or the arguments: "the object has already been deleted or was not completely created.

  + CategoryInfo: NotSpecified: (:)) [], MethodInvocationException)

  + FullyQualifiedErrorId: DotNetMethodException

  Any help is greatly appreciated.

  It's one of the drawbacks of the Onyx, the generated code is endless.

  There is no need to use the ID in the CSV file, simply use the names.

  And there is no need to specify a data store for the vDisk if you migrating the data store even other files such as the virtual machine

  connect-viserver VCENTERSERVER.domain.local
  $vms = Import-CSV "G:\temp\scripts\relocate.csv" foreach ($vm in $vms) {
    $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec  $spec.datastore = (Get-Datastore -Name $vm.DatastoreName).ExtensionData.MoRef  $spec.pool = (Get-ResourcePool -Name $vm.ResourcePoolName).ExtensionData.MoRef  $spec.host = (Get-VMHost -Name $vm.ESXHostName).ExtensionData.MoRef
  
    $vmObj = Get-VM -Name $vm.Name | Get-View  $vmObj.RelocateVM_Task($spec, "defaultPriority")
  }
  

  And your CSV might look like this

  Name, DatastoreName, ResourcePoolName, ESXHostName

  VM1, DS1, Pool1 ESX1

  VM2, DS1, Pool2, ESX2

• Cold migration domain controller

  Hello.

  I am migrating from a server ESXi 5.0u1 with either direct-attached storage.  I have three systems to move, all in a Windows 2008/2003 domain.

  The three systems are a Windows 7 workstation and a Windows 2008 domain controller or a Windows 2008 Exchange 2010 server.  They have all been created directly on the ESXi host.

  First, I tested my migration trying to move the Windows 7 workstation.

  I turned off the desktop and Veeam FastSCP for copying the files of comments from vm.  I added the .vmx for new host inventory and tol host file I made a move instead of a copy.

  When I turned on the guest system migrated and tried to login, I get the following error:

  "The trust relationship between this workstation and the primary domain failed."

  I found a few posts that suggest leaving the system and join the domain.  Not that big a deal I guess for a workstation.  But I would like to avoid this error when I migrate my DC and the Exchange Server.

  What can I do to properly migrate these systems in domain?  Use Vmware Converter instead of Veeam?

  VMware offers a trial license of a tool that would allow a live migration (vmotion)?  Always anxious to avoid this error field problem, however.

  Thank you.

  Yes, you can view the current time - and the NTP settings you have configured if all goes well - in tab Configuration 'Software'-> 'Configuration of time. "

  BTW. where to install an ESXi host the time in the BIOS must be set to time current UTC.

• Migration cold - how many simultaneous servers

  We have a customer moving servers from one host to another host in the same ms. We do a migration cold because there are some limitations to this customer and no SAN/storage network so all local drives on the host server. Although we can now do vMotion without storage applications SAN/network has some limitations too and client wants to move which is supported by the seller and do not go by what VMWare can support. Our question is when we make cold migration using vCenter doing this option, stop comments right click migrate host and data store servers how can we move simultaneously at once a single server at a time, or we can do more than one. Any help would be appreciated. I am less familiar with this side of vmware, so feel free to ask for more information in case if I did not understand our scenario.

  VCenter is 5.5

  Esxi host on source version is 5.1 and destination is 5.5.

  There is a little math to do, but you can see the rates here: https://pubs.vmware.com/vsphere-55/index.jsp?topic=%2Fcom.vmware.vsphere.vcenterhost.doc%2FGUID-25EA5833-03B5-4EDD-A167-87578B8009B3.html

• Issue of Migration cold

  When you perform a cold migration when starting from CD you get a prompt that shows "no available network connection. You want to update the settings of the network at this time. "

  My question is when you click Yes, you get the options to statically assign IP, subnet, default gateway, and dns...

  Here - would you enter the IP address of the physical server you are trying to migrate? or would that be a new IP for VMware Converter to connect to the network?

  It depends on the operating system and the type/use of the system (e.g. domain controller, Exchange server,...).

  Basically, you shouldn't ever hot convert a domain controller, because this will usually damage the AD. For Exchange of data bases, etc., you should consider to stop services to have a consistent state without open files.

• cold vsphere 4.1 - should migration take how long?

  Hello!

  We begin the process of upgrading our hosts and components vSphere 4.1 to 5.5.  We have to increase the RAM on the hosts and therefore need to move some virtual machines between hosts.

  Some of these virtual machines have no VM Tools installed, so they must be cold migrated.  Stop, migrate, restart, rinse and repeat.

  I'll do some tests, but my previous experience on it's a little blurry.  Let's not storage, just the virtual machine.  I remember this will only take a couple minutes to complete.

  What is your experience with this kind of cold migration how long does?

  Thanks in advance!

• Traffic cold to migrate a virtual machine

  Hello

  This statement is correct: "when I have cold migration a (engine off) vm local storage to a local storage of another of ESXi through vCenter ESXi, the flow of traffic through the management-traffic-portgroup, not the vmotion portgroup?"

  This is because when I migrate a warm , no matter it is a vmotion or a vmotion with storage vmotion, then the flow of traffic through the port of vmotion group. This is the behavior I expect. But why is the traffic not through the vmotion portgroup as well when I do a cold migration? Or is there a bad configuration? But I have different ports on different nic groups and there are different subnets configured... and each port group has only one type of traffic affected.

  I am just a student: what happens if I have a network vmotion 10 GB and a 1 GB management network? When you perform a cold migration, traffic will choose the 1-GB-connection slow? Everyone is to give all the bandwidth as possible for vmotion, but in this scenario, traffic passes through the management network? I don't know--in most cases, we do a vmotion or svmotion. But I was amazed when I detected, that things from traffic port management group and not group ports vmotion...

  Is it really the behavior by default as described?

  Best regards

  Roland

  Yes that's right - with migration cold, the data move on the management network and it is the behavior of traffic movement not through network vMotion as a Migration cold isn't vMotion - also as your shared storage is compatible with VMware Storage API or will not depends on if data remains on your storage network or public network you.

  Also 10 GB I think is overkill for your vmotion network - it is designed to work with 1 GB.

• vDS to migration cold vDS

  Is there an easier way to cold migrate a VM from vDS VDS service without removing the vNIC?

  My current environment has 2 data centers physically separated with about 15 guests in each.  vCenter is configured with each data center physical with a single Datacenter/15-host Cluster and vDS defined for each.

  The current process before the cold migration is to remove the vNIC (s), and then migrate the virtual machine to the desired location.  Is there a way to better or easier to do this?  My dvPgs exactly the same labelling would solve this problem?

  For this kind of scenario, we have created the following workaround solution in our environment:

  Create an additional vDS (we called it TransferSwitch), add all the guests of all the centres of data/clusters, but without any physical connection.

  A migration process cold one cluster/datacenter to another then realized in three steps:

  1. connect the NIC of the virtual machine to the TransferSwitch

  2 cold migrate the virtual computer to the destination

  3. connect the NIC of the virtual machine to the destination vDS

  This avoids remove/re-adding NIC of the virtual machine and all the consequences (as a new device detected in the guest operating system, with a different MAC address).

  You can create the right TransferSwitch temporarily for each VM migration, but we decided to keep everything permanently.

• What is 'Migration to cold with resettlement of the file'?

  Hello

  I just read http://kb.vmware.com/kb/1005241 on the migration of virtual machines with attached RDM. The document states that the following is true when you are migrating cold with moving file.

  When you are migrating cold a VM with RDM attached to it, the content of the raw LUN mapped by ROW is copied into a new hard to destination file, effectively converting or cloning a raw LUN in a virtual disk. This also applies when the virtual machine is not moving between ESX hosts. In this process, your raw LUN origin is left intact. However, the virtual machine is more reads or writes to it. Instead, the newly created virtual disk is used.
  I just tested this and migrated cold a VM with vRDM attached to another data store. However, the vRDM has not converted to a virtual drive, but remained as a vRDM. Is the "Cold Migration with file transfer" something different than right-clicking on the VMS in vCenter, choose "migrate" then 'Datastore change' or 'change of host and data store '?
  Thank you
  Michael

  Hello

  Glad to hear that it worked for you, yes the document isn't very desciptive processes to do it, the only reason that I know how to do it is previous experience.

• Cold using vMotion migration between data warehouses

  To perform a migration cold between 2 not the source ESX servers and the host ESX destination need to see two data stores?

  I have a host ESX 3.5 with 1 data store called data01 and a host ESXi 5.0 with a data store called data02. Using vCenter to manage the two ESX host - what I want to turn off a virtual running on the 3.5 host computer and perform a migration cold, including a data store move to 5.0 host.

  
  Can this be achieved?

  I am unable to storage area presented to the ESX host 3.5 to the host of 5.0 and also unable to storage 5.0 to 3.5 host.

  The OP is talking about a cold migration.  In the scenario described, it doesn't have to be a shared storage.  As long as the migration cold remains in the same instance of vCenter, there should be no problem.

• Migration cold with snapshots

  What is the best way to cold migrate a virtual machine with photos, if snapshots may be taken first?

  Thank you

  Hello

  (1) turn off the virtual machine. Remove the virtual machine from the inventory...

  (2) move the file to the virtual machine of the old data to the new data store store & browse the data store.

  Add 3) the virtual machine to the new data store inventory.

  (4) it will contain snapshots.
