• Impossible to disassemble the data store

  Hello

  I am getting below error when I was trying to United Nations set up the data store.

  Call "HostDatastoreSystem.RemoveDatastore" of object "datastoreSystem-15" on VCenter Server failed. ' "

  It seems there are two file inside the data store and I was not able to delete it also. This swap for old file
  models which does not exist now.

  Please let me know how I can remove this file from the shell of ESXi forcefully command so that I could not get the data store.

  Kind regards

  Check if it has deployed VM from this template and set the swapfile strategy to stay with the Virtual Machine. See also, if you are able to delete other files vswp with this command:

  
  rm - rf new model - 8d25d1fe.vswp

• Ghost in a data store VMs

  Hello;

  I need to remove a database on my ESXi 5.5 HA/DRS cluster due to storage issues.

  VCenter watch 3 VMs running in the data store but it is not a correct information. Vcenter also shows that space 0 B used for each virtual computer. So vcenter won't let me not disassemble the data store. When I look at the parameters of each virtual computer, these virtual machines running in a different data store.

  When I try svmotion, it says completed successfully but VMs are still stuck in the data store.

  Can I turn off all 3 VMs, remove/remove datastore and turn on those virtual machines, but I find that it is so risky. Because these virtual machines are essential and hundreds of GB.

  How can I remove the data safely store?

  Thanks and greetings

  Tirelibirefe

  First of all, check if one of those VMS have any ISO mounted this data store... and even if it there is no ISO standard not mounted, check if there is place of the snapshot on the virtual machines and delete them, cause maybe the ISO was mounted when the snapshot was taken.

• Disassemble 5.1 data store

  I had a script that went through and was able to disassemble and then detached datastore in 5.0.  now the powercli 5.1 update has ignored the following functions and I was wondering if there is a better way to do it.

  Remove datastore

  Remove datastore

  Datastore Unmount and Detach-data store features come from the following document: functions of assembly/disassembly of Detach/Attach data store. Download the script from the document and load functions in your session before you run your own script.

• Disassemble the help of data store, modify the existing function

  I would like to change the below function to pass a single host settings and a data store single instead of doing all THE hosts connected to the lun.  I would like to be able to specify the news.

  Function Remove Datastore { }

  [CmdletBinding()]

  Param

  (

  [Parameter (ValueFromPipeline

  = $true )]

  $Datastore

  )

  Process of

  {

  if (-not $Datastore) {

  Write-Host "No data not defined as an input store"

  Output

  }

  Foreach ($ds in $Datastore) {

  $hostviewDSDiskName = $ds. ExtensionData.Info.vmfs.extent [0]. DISKNAME

  if ($ds. ExtensionData.Host) { }

  $attachedHosts = $ds. ExtensionData.Host

  Foreach ()$VMHost en $attachedHosts) {

  $hostview = Get-View $VMHost. Key

  $StorageSys = Get-View $HostView. ConfigManager.StorageSystem

  Write-Host 'Disassembly $($DS.) VMFS Datastore. The name) host $($hostview ). «' «Name)...»»»

  $StorageSys . UnmountVmfsVolume ($DS.) ExtensionData.Info.vmfs.uuid);

  }

  }

  }

  }

  I tried to change it to this, but don't think I have it correct.  I would run like this preference:

  $esx = get-vmhost hostname

  Disassemble-Datastore - VMHost $esx - data datastorename store

  Function

  Remove Datastore {

  [CmdletBinding()]

  param (

  [

  [ VMware.VimAutomation.ViCore.Impl.V1.Inventory.VMHostImpl ]$VMHost

  [

  string ]$Datastore

  )

  Process of {

  if (-not $Datastore) {

  Write-Host "No data not defined as an input store"

  Output

  }

  $hostview = Get-View $VMHost. Key

  $StorageSys = Get-View $HostView. ConfigManager.StorageSystem

  #Write - Host "disassembly $($DS.) VMFS Datastore The name) host $($hostview.) (Name)... »

  $StorageSys . UnmountVmfsVolume ($Datastore.) ExtensionData.Info.vmfs.uuid);

  }

  }

  Try it like this

  function Unmount-Datastore {
    [CmdletBinding()]
    param(
      [VMware.VimAutomation.ViCore.Impl.V1.Inventory.VMHostImpl]$VMHost,    [string]$Datastore  )
  
    process {
      if (-not $Datastore) {
        Write-Host "No Datastore defined as input"      exit    }
  
      $ds = Get-Datastore -Name $Datastore    $hostview = Get-View $VMHost    $StorageSys = Get-View $HostView.ConfigManager.StorageSystem    #Write-Host "Unmounting VMFS Datastore $($DS.Name) from host $($hostview.Name)..."
      $StorageSys.UnmountVmfsVolume($ds.ExtensionData.Info.vmfs.uuid)  }
  }
  

  Given that the data store is defined as [string] I suppose you pass the datastorename.

  So you'll need to get the data in $ds store object

• Impossible to add storage as data store

  Hello

  I started with 4 esxi servers 5 to test the object with the method of assessment and added the common datastore on all 4 servers for virtual machines that worked very well. but the tests I formatted 2 esxi servers and installed ESXi 4 top, now when I am adding common storage in these 2 ESXi 4 Server I get the error attached, I have found the solution so that it can delete the partition with fdisk command to this logical unit number, but this LUN is common for all 4 servers and virtual machines running on it for 2 ESXi 5 host , so please, someone has the solution to this problem

  Another problem is that showing time in hostd.log file is different because I have configured in Setup esxi why its different time showing.

• Impossible to mount any NFS data store: unable to resolve host name '&lt; obsolete Server &gt; '.

  Hello

  On a particular ESXi server, whenever I try to mount any NFS data store, I get this error message:

  Call "HostDatastoreSystem.CreateNasDatastore" of object "ha-datastoresystem" on ESXi '172.22.216.64' failed.
  Operation failed, the diagnostic report: unable to resolve host name 'cosmo '.

  Always mention hostname 'cosmo', no matter what server I'm actually trying to mount. 172.22.216.64 is the exact address of the ESXi server.

  'cosmo' was the former name of a desktop linux machine, several months ago has re-installed and renamed in the process. So 'cosmo' is no more and it's just expected that 'cosmo' cannot be resolved. However, the error message mentioning 'cosmo' occurs regardless of what server I try to mount a NFS datastore of. I can't find any references to 'cosmo' in the ESXi server configuration in the vSphere client (although I don't know exactly where to look). I remember that at one point, a NFS datastore was mounted temporarily to 'cosmo' to host the ISO debug files. But no more.

  I tried this same sharing of an another ESXi (running the same version of ESXi) mounted in the same subnet (works great), and I also tried to mount a new NFS share on a server where the ESXi already had another NFS data store mounted from the same server (the data store already mounted works fine (, but attempts to connect to a new data store on the same failed server mentioning the independent 'cosmo' server as mentioned above). I tried to restart the ESXi server, but the problem persists after restarting.

  I'm under vSphere client 5.0.0 Build 455964 and ESXi 5.0.0 - 469512-standard with the free license. Because of the free license (I think), I don't have SSH access on the server. (Is that right?)

  How to work around the error message mentioning the obsolete server 'cosmo '? The only thing I can think of right now is to move all data from the local data store to a store of data already mounted, reinstall the ESXi server and give all the data. I'm hoping for a simpler solution! :-)

• SWAP file data store remove issue

  Hello

  I'm currently moving VMs to the data store newly created as well the datastore file swap. I have already change on all ESXi hosts, the data store were swap file will reside, however, I have still a few virtual machines on the old data store. I know not if I vMotion virtual machines from one host to another it will change the location for the swap file. My question is, can I just remove the old data store without affecting production not VMs remained the swapfile on the old location? Just try to find a solution faster than vMotion every single one of the virtual machines.

  Thanks for any suggestions or comments!

  Chris

  Hello

  As long as all hosts are no longer using the data store and the cluster is not defined using volume swapfile host (rather than storing with VM) then you should be able to disassemble the old swap partition.

  Bare in mind, vMotion/svMotion a virtual computer, you must be sure to move all the files and the virtual machine is set to store his exchange with the virtual machine files. Check that the old swap partition is no longer in use, and then take it apart. In theory the fastest way is to ensure that all VMs are defined to store swap with virtual machine files to the off and on again, forcing a new .vswp file in the same device. But it would of course affect your VM availability.

  I've seen in the past that even if the volume was no longer used by the guests, that guests required a restart until I managed to remove the old Exchange store data, just in case you meet that!

• Good way to delete a data store

  I'm not sure this is the right forumr for my question. If not, can someone please point me to the right one?

  I need to remove two LUNS on a storage (HP LeftHand).

  The lun host 2 warehouses of data used by a 5.5 vSphere cluster composed of 3 5.5 U2 ESXi servers.

  I have to perform the activity during execution of virtual machines and I can not create any problem or performance for VMS running problem.

  So I need to create a checklist as accurate and complete as possible...

  Here's my Checklist:

  • I removed all the VMS since data warehouses
  • I deleted all the files from data warehouses
  • I removed data warehouses from the list of data used by pulsation HA stores
  • I checked that the sacratchconfig. ConfiguredScratchLocation for each node indicates a different datadtore of those that I am giung to remove

  Can I safely remove the files inside the folder .vSphere-HA?
  Should what else you check before removing the data store?

  Is there anything else I should consider?

  Concerning

  Marius

  For well detach and remove datatores take a look at http://kb.vmware.com/kb/2004605.

  In fact, there is nothing which will cause problems. If you try to take it apart (or delete) a data store it will work either (if anything accesses the database), or you receive an error/warning message. Once a datatore is disassembled or deleted, you must detach the LUNS for each host, and - after unpresenting a LUN of Lefthand CMC and run a new analysis on the hosts - you can do the cleaning (esxcli storage core detached unit remove d NAA_ID) on the hosts.

• How to migrate Office persistent link clones of workstations for the new data store

  Hello. We have clones of persistent link to view running in the environment from our view. We need to migrate these desktops to new storage. Rebalancing is out as this will include a refresh operation - destroy anything and everything installed in c:\ of the user. Is there a method to migrate Desktop clone link persistent to a new data store, while keeping the office in the same exact state (i.e. c:\ is not updated).

  Thank you

  Never say impossible. I came across the solution when I read the article by Duncan Epping:

  http://www.yellow-bricks.com/2012/03/15/Dr-of-view-persistent-linked-clone-desktops/

  I have that for my situation. Basically, replicate data from view in the new storage warehouses. Set up data warehouses replicated without re-signing with the cluster of ESXi. Turn the power off and unsubscribe the vCenter view workstations. Save the workstations from the data store replicated/mounted to vCenter and power over desktop computers.

  VCenter, nothing dramatic has happened if she sees just as vm being unregistered and re-recorded activity from the same exact data store (the same UUID). View Admin is happy because he sees just the events as desktop computers that have been turned off and then subsequently in reverse. Nothing has changed regarding the database to view ADAM, we still use the same data warehouses.

  I have already tested before for a scenario of View DR, and he succeeded. Between remembering who and Duncan's article helped me to adapt the same process for this. Nothing is impossible
