• Storage vmotion with several virtual disks

  I have a couple of virtual machines with virtual disks on them.  I have a need to pass one of the virtual disks in a different lun while leaving others in the current location.  I would like to move this disk without impact on our users, which means that I like to keep the operational machine.  I did several Vmotions storage with great success.  I want to know is if there is a way to use Storage Vmotion and tell him to move only a single virtual disk on a multi VM disk.

  Does anyone know if there is a way to do this?

  Thank you!

  Download and install the RCLI.

  Run the sVMotion intereactive mode.  This will guide you through the process with the ability to move the individual disks.

  command line must start with

• Storage VMotion for several data stores

  I'm looking for some advice and assistance with the help of the vSphere PowerCLI to SVMotions.

  I found that I can use virtual vmname Get-machine | Move-VM - datastore (Get-Datastore datastorename) that has worked very well and I was ready to roll. However, it occurred to me that I can only refer to a data store in the cmdlet and some of our virtual machines have their drives located on different data warehouses.

  So I set up a test VM with two disks of different data warehouses and began a SVMotion. The result was that it has migrated all disks in their separate data warehouses in a single folder on the target.

  What I need to be able to do is to migrate a disk and leave the other in its original location, or migrate two disks of different locations in two different places again. As you can do if you switch the machine virtual and migrate through the graphical interface, moving storage with advanced options (and probably what you can do via the graphical interface with the virtual machine in vSphere).

  I've got ESX 3.5 Update 5 with vCenter 2.5 update 6 If no GUI in VirtualCenter and the free snap option not taken in charge is not an option.

  Is there a way to do it with the PowerCLI or am I limited to migration the data store's unique virtual machine?

  Thank you very much.

  This can be achieved using the. RelocateVM_Task() method of the VirtualMachine SDK object

  See the code below:

  $configDatastoreName = "DataStore_01"
  $HardDisk1DatastoreName = "DataStore_02"
  $HardDisk2DatastoreName = "Datastore_03"
  
  $vm = Get-VM VM001
  
  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec
  #Get MoRef for Destination datastore for Config files
  $spec.Datastore = (Get-Datastore $configDatastoreName | Get-View).MoRef
  
  #for each disk specify where the vmdk files should be placed.
  #If a vmdk should NOT be moved, enter its CURRENT datastore
  #If you forget to specify a disks location, it will be moved to the datastore
  #specified in $spec.Datastore
  
  #HardDisk 1
  $objDisk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
  $objDisk.DiskID = $vm.HardDisks[0].Id.Split('/')[1]
  $objDisk.DataStore = (Get-Datastore $HardDisk1DatastoreName | Get-View).MoRef
  $spec.Disk += $objDisk
  
  #HardDisk 2
  $objDisk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
  $objDisk.DiskID = $vm.HardDisks[1].Id.Split('/')[1]
  $objDisk.DataStore = (Get-Datastore $HardDisk2DatastoreName | Get-View).MoRef
  $spec.Disk += $objDisk
  
  #When all harddisks are specified call the RelocateVM_task()
  $vm.ExtensionData.RelocateVM_Task($spec, "defaultPriority")

• Can not put on the virtual computer after Storage VMotion

  I use the snap for the customer VI do some storage vmotion, where I can best use our space on our tables. I have a particular virtual machine that I transferred autour storage that has a total of 3 VMDK, all on separate LUNS. As soon as I moved them all in the right place, where I wanted them, I can't turn on the virtual machine because it says there is no space available on the device. I am trying to boot the machine with 4 GB of memory, the boot LUN more than 400 GB free on it. The other two LUNS have 225 MB, and 192 MB of free space. I can only start the machine if I change the memory of 192 MB or less. I know that problems with the file exchange and memory overhead, but this virtual machine has always run with these two LUNS with very little space. I can only assume it is somehow related to the storage vmotion. The pagefile is set to store the virtual machine and I'm still having the problem. Need help.

  Storage vmotion the VMX file of the LUN with more space (easier) or add manually a config parameter (settings, Options, general, settings) sched.swap.dir = / vmfs/volumes/DS/Machine

  (where DS and Machine related to your environment).

• Photos of virtual machines with multiple disks on different LUNS - Question

  I have some questions on how to manage the snapshots of virtual machines with multiple disks on different LUNS.  First of all, the LUNS are VMFS.  We are just starting to add virtual machines with dedicated for data storage format VMFS LUNS.  I don't think an extra space must be made for snapshots, as well as at least 100 GB LUN is required to store the data, and then say, add about 25 to 50% of this amount?  Set the 100 GB vmdk file but have the GB from 25 to 50 additional disk space for snapshots, if necessary (rather than just to get a unit number logic needed 100 GB of data and devote all of the 100 GB to the vmdk file).  In addition, if a virtual machine has several files vmdk on different LUNS, which will be a problem to take a snapshot, and is it possible to do just a snapshot of a disk of a virtual computer (as the volume of the BONE)?

  Thanks for any help.

  Snapshot files are created in the home folder of the VM by default for all virtual disks, no matter on what data store they are. You must make sure you have enough free disk space on the data store for snapshots.

  If you want to exclude a virtual disks of taking snapshots, you can set it to 'Independent' - 'Persistent' machine virtual settings to the HARD drive.

• Storage vMotion a VM except disk that is in another data store

  Hello

  I'm looking to convert a large number of virtual machines clones related to thick.  I decided the best way to do this is probably a simple a storage vMotion, but all the virtual machines have a secondary drive that is in another data store.  I have to make sure that disk #2 stays at its current location, while the machine virtual (Config and disk #1 files) are transferred to a new data store data store.

  I figured out how to move a virtual machine complete or a single disc but not a virtual machine under a disc.  I am able to make it through the advanced options of puissancela vSphere client so I guess it is techinically possible.

  Pointers or other ideas would be greatly appreciated.

  Kind regards

  You will need to use the API method, see for example Re: using several data stores, cannot migrate the vmx file in a data store

• Storage control IO to multiple LUNS on 1 table

  Yesterday I read on I/o control of storage in vSphere, and it seems logical to me. However, what has not been clarified is if/how it works when you multiple LUNS on the same table, and how you set it up in such a scenario.

  In our environment, we have 2 bays EqualLogic (PS100 and PS6000), with the array created as a single group with a little less of 7 TB of space in RAID 10.

  Most of our data is shared between 3 LUNs, 1 store our VDIs, the 2 other storage server VM, set up a single data store with a certain extent. (I'm trying to develop a plan to better distribute our virtual machines for a server) to get rid of the measure and 2) recover unused space (the server of virtual machines are only about 3 TB in size, but because of servers added and retired, takes more space on the San of 3.9 to).

  Thank you

  Each data store gets its own statistics IGCS, so each of them is controlled indepedently.

• Storage VMotion for a virtual machine with SAN LUNS attached to it. They are all going to?

  Hello

  Don't know which section of this post, so sorry if its wrong.

  We are eager to Storage VMotion of our SQL VM. These are our SAN 3040 of NetApp. In the virtual machine (windows 2003), they have also connected to the network SAN NetApp 3040 LUN.

  What I need to know is, if we tried to do the other (NetApp 3170) SAN Storage VMotion problems due to the fact that its storage not only fast vMotioning of VMs its self, but also the LUN or LUNS will remain on 3040, and the virtual machines moved to the 3170?

  Who is?

  If more info should help just shout!

  Cheers in advance...

  RDM's Raw card device.

  As I posted earlier, you need to move data to the Raw LUN for LUN Raw new either through data copy inside the VM if you map the new LUNS brutes who him or copy.

• I can storage vMotion two popular VMS with shared disks?

  I have an ESX 3.0.2 Server with local storage and two ESX 3.5 with fiber channel SAN servers. Two VM sharing disks and run it on the computer with only the local storage. Can I use storage vMotion to move these to a 3.5 servers and more at the SAN?

  If not; can I migrate the servers (when closed) to the SAN and 3.5 servers without breaking the links on shared disks?

  If you close the virtual machines and migrate them, you should be able to access the disks - as the sVmotion update pointers in the vmx file.

  If you upsize and lose access to the disk, you will need to do is open the.vmx file for each virtual computer and update the path specified for each disc, not too hard to fix at all. -If you don't like that, you can simply remove and re-add the disc in the VM properties

• Storage VMotion in LUN protected with SRM

  Hello

  I don't have RS in my environment and do not know what will happen in the next version of SRM (Version 1.5), but I'm caurios to know the answer to this question.

  Now that vSphere officially supports Storage VMotion, is it supported in SRM as well? Which means that if you have two LUNS protected by SRM in a DataCenter. What happens if use you Storage VMotion LUN to one another. (Both protected)

  Move the files in your DR Site as well? No need to reproduce on the internet?

  Thank you

  Currently, if you a data store SVMotion not replicated to replicated store listed in MRS. VM pop-ups in the Protection Group - like 'not protected' as a whole new VM. You can then right-click and choose to protect...

  It is less smooth vice versa - it is as "not configured" and you need to delete manually the list of SRM...

  My free guide to SRM - covers this 179 page...

• move only one disk per storage vmotion

  Hello

  We currently have the problem that we have to move only one disk with Storage Vmotion. I found the 'move-VM"for this cmdlet, but I found no option to move single vmdk and not the whole VM?

  Can someone help me.

  Thank you

  There seems to be some problems with the RelocateVM_Task method.

  See also Powershell sVmotion number.

  After some trial and error, I discovered that when you give the data store target twice (in VirtualMachineRelocateSpecDiskLocator object and the VirtualMachineRelocateSpec) the sVMotion seems to work.

  $vmName = 
  $vmDisk =                # Ex "Hard Disk 2"
  $tgtDS = 
  
  $vm = Get-View -ViewType VirtualMachine -Filter @{"Name"=$vmName}
  foreach($dev in $vm.Config.Hardware.Device){
       if ($dev.DeviceInfo.Label -eq $vmDisk){
            $diskId = $dev.Key
       }
  }
  
  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec
  $diskspec = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
  $diskspec.Datastore = (Get-Datastore -Name $tgtDS | Get-View).MoRef
  $diskspec.diskId = $diskId
  $spec.Disk = @($diskspec)
  $spec.Datastore = $diskspec.Datastore
  $spec.Host = $vm.Summary.Runtime.Host
  
  $task = Get-View ($vm.RelocateVM_Task($spec, "lowpriority"))
  while($task.Info.Status -eq "running" -or $task.Info.Status -eq "queued"){
       $task.UpdateView()

• storage vmotion 4 1 TB vmdk to a new data store 4TB on 5.5

  All,

  Benefit in performance if the 4 storage vmotion VMDK located on 4 separate data warehouses in a newly created 4TB data store. with 5.5 capacity 62, I was hoping that someone could tell me.

  I appreciate it

  Well well, the response - as before - is "it depends...". ».

  If you want to use a large drive or multiple small disks depends on the structure of data. If you can not divide the data into departments for example, projects, home/profile,... you can be better with a single large disk. Don't forget to use a GPT partition table, and you need to check if for example your backup software can handle that. Some image/VM based backup applications can backup and restore virtual drives very well, but do not have the ability to file level restore! Also don't forget that - disaster - restoration such a large virtual disk will take a significant amount of time during which data is not available for users. If the data structure allows to distribute to several virtual disks (you can always use DFS to present the data through a single share), I prefer this over the large virtual disk. With the smallest disks virtual, you will certainly have to watch each of them for free disk space, but you can increase the size of disk individually and restoration of a single virtual disk can be done much more quickly (with other discs still online / available to users).

• Storage VMotion VM > 2 TB

  Hi, we will implement 5 ESXi, and multiple LUNS are all size to 2 TB. In addition also have several virtual machines with multiple VMDK files, and in some cases, the total size of all the VMDK files for a virtual machine unique exceeds 2 TB, i.e. the VMDK files for the virtual machine are spread over 2 or more LUNS.

  I have a question consider that to Storage VMotion, if I decide to SVMotion a virtual machine > 2 TB, vSphere allows you to choose what data LUN store to move the virtual machine. I know that with small virtual machines a single destination LUN can be selected, but for a virtual machine large multiple LUNS can be selected?

  Thank you

  Of course, you can specify where you want to move your VMDK.

  In the svMotion window you have an advance button. Here, you get the options to each VMDK + virtual machine configuration files.

  Kind regards
