How to create parallel snapshots

• How to create parallel tasks using parallel for loops

  Hello

  I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

  I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

  Is it possible to replace something like

  

  by

  

  and that for performing these tasks in parallel loop (on different cores / in different threads)?

  I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

  The benefits of the Show method in the second photo for me are:

  * takes less space

  * changes need be made only once

  * less blocks, son and other things makes it clearer what is happening.

  * flexibility of the actual number of tasks running (8 available runtime instances)

  * If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

  Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

  Best regards

  Frans

  Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

• How to create the snapshot to the remote data store?

  Hi all.

  I have esxi 4.1 now if I run the snapshot in the snapshot file created on the host server, but I want to create the file snapshot directly to remote NAS. Can I do this?

  Thanks in advance.

  best account.

  Dan.

  check this, you can set a different location of snapshot: http://blog.vmpros.nl/2009/05/14/vmware-creating-snapshots-in-a-different-location-than-default-virtual-machine-directory-1002929/

• How to create an effective script that mass deletes snapshots

  our company is currently using a product that drives the operating system and software updates for our virtual machines and takes a snapshot before pushing updates in case something breaks. the problem is that the same software does not remove the pictures until next update button and you're just too long we wait with snapshots lying around. what I did to remedy this situation is I built the below script and configured it as a task.

  # Add the snap-snap powercli in
  Add-PSSnapin VMware.VimAutomation.Core

  # Connect to an instance of vCenter
  $strviserver = "vCenterServer".
  SE connect-VIServer $strviserver

  # Get all of the snapshots for each virtual machine in the vcenter, then delete them
  Get - VM | Get-Snapshot - name "updates" | Remove-Snapshot - confirm: $false

  # Remove the snap-snap powercli in
  Remove-PSSnapin VMware.VimAutomation.Core

  It works, but it is not nearly as effective as I wish it were. Essentially, the script currently removes a snapshot at a time right now. I want so he can find any snapshot on this server vcenter by the same specified name and submit the task deletion-Snapshot for each snapshot at the same time. This should cause a lot of tasks to try and tail. The effective result would be that vCenter will treat all instant destruction because it has resources to do in a given time and will address the queue there resources.  If someone can tell me how to do this or something better, I would really appreciate it! Thanks in advance!

  You can consider using the RunAsync switch on the cmdlet Remove-Snapshot .

  In this way, that the script will continue while delete the snapshot is still running.

  Note that there is obviously that a limit on how many parallel snapshot removes that may occur due to the resources available.

• 'Create a snapshot of the Virtual Machine' suspended the process - how to kill?

  I tried to rename a virtual machine when I received a message from VCenter that "another task is already underway."

  I did some research and found that the virtual machine, I am trying to rename is currently creating a snapshot of the Virtual Machine.  Or - at least the host thinks Yes.

  The snap was initiated by vpxuser about 20:00 in the night a few days - and is still ongoing.  I can't kill him since the VIC when it is directly attached to the host.

  Looking to my data warehouses - I don't see that he actually created the snap, because I see no 0000001 or something like that.   At this point, I don't like, I don't know why he even launched the snap in the first place.

  Is there a way I can kill that process with the help of the console?   It's hosted on vSphere 4.

• Who created the snapshot

  No idea how I can relatemy Get-Snapshot information information Get-VIEvent to determine who created a snapshot?

  Thank you

  Alan

  Small question, but a long answer. In the end, I arrived.

  There were a few quirks in writing this script.

  (1) the timestamp of creation in the event object is not always exactly the same as the timestamp in the property instant VirtualMachine.

  The solution is to use the entity property of the task to get the timestamp of the snapshot.

  (2) the Get-ViEvent cmdlet returns a VimApi.ManagedObjectReference instead of a VMware.Vim.ManagedObjectReference.

  So this isn't a big problem because I can easily convert a MoRef (unfortunately not by casting).

  (3) the speed of the Get-ViEvent cmdlet is not ideal compered to the task of the collector of the API

  (2) and 3) I decided to go for the collector's working methods.

  The flow of the script is very simple.

  First create a hash of all the tasks table that created snapshots on specific comments.

  The key in the hash table is the name of the guest concatenated with the snapshot creation timestamp.

  Then the script use the cmdlet Get-Snapshot to retrieve snapshots for the guests.

  This output is built a key and then the key is used to search for the user in the hash table.

  The user property is added to the SnapshotImpl object.

  function Get-SnapshotTree{
       param($tree, $target)
  
       $found = $null
       foreach($elem in $tree){
            if($elem.Snapshot.Value -eq $target.Value){
                 $found = $elem
                 continue
            }
       }
       if($found -eq $null -and $elem.ChildSnapshotList -ne $null){
            $found = Get-SnapshotTree $elem.ChildSnapshotList $target
       }
  
       return $found
  }
  
  $daysBack = 3                            # How many days back from now
  $guestName =                           # The name of the guest
  
  $tasknumber = 999                       # Windowsize of the Task collector
  
  #$serviceInstance = get-view ServiceInstance
  $taskMgr = Get-View TaskManager
  
  # Create hash table. Each entry is a create snapshot task
  $report = @{}
  
  $filter = New-Object VMware.Vim.TaskFilterSpec
  $filter.Time = New-Object VMware.Vim.TaskFilterSpecByTime
  $filter.Time.beginTime = (Get-Date).AddDays(-$daysBack)
  $filter.Time.timeType = "startedTime"
  
  $collectionImpl = Get-View ($taskMgr.CreateCollectorForTasks($filter))
  
  $dummy = $collectionImpl.RewindCollector
  $collection = $collectionImpl.ReadNextTasks($tasknumber)
  while($collection -ne $null){
       $collection | where {$_.DescriptionId -eq "VirtualMachine.createSnapshot" -and $_.State -eq "success" -and $_.EntityName -eq $guestName} | %{
            $row = New-Object PsObject
            $row | Add-Member -MemberType NoteProperty -Name User -Value $_.Reason.UserName
            $vm = Get-View $_.Entity
          $snapshot = Get-SnapshotTree $vm.Snapshot.RootSnapshotList $_.Result
            $key = $_.EntityName + "&" + ($snapshot.CreateTime.ToString())
            $report[$key] = $row
       }
       $collection = $collectionImpl.ReadNextTasks($tasknumber)
  }
  $collectionImpl.DestroyCollector()
  
  # Get the guest's snapshots and add the user
  $snapshotsExtra = Get-VM $guestName | Get-Snapshot | % {
       $key = $_.vm.Name + "&" + ($_.Created.ToString())
       if($report.ContainsKey($key)){
            $_ | Add-Member -MemberType NoteProperty -Name User -Value $report[$key].User
       }
       $_
  }
  
  $snapshotsExtra | Export-Csv "C:\SnapshotsExtra.csv" -NoTypeInformation -UseCulture
  

  Note1: the parameter - UseCulture to the Export-Csv cmdlet is PS v2 CTP3

  Note 2: it should not be too difficult to convert the script to handle all the guests instead of one. The name of the guest is already in the key in the hash table.

• More about "ERROR: failed to create a snapshot of a volume of the source.

  I saw the previous posts on this and have tried to follow all the advice, but nothing helped.  I am running XP and you have two hard drives, NTFS and both have plenty of space.  My destination is an external hard drive, FAT32, with plenty of room.  I get the ERROR message: failed to create a snapshot of a volume of the source. Ppossible causes include not seen all NTFS volumes on Windows XP or Windows 2003 source systems with no is not enough of disk space.

  I installed the converter as an administrator, I rebooted several times, I ran / f checkdsk on both hard drives and external drives, I have disabled all the services that I am uncomfortable, turn off, but just, I get this message.  I have attached the log file.

  Thanks for any help.

• How to create a PDF/X1a on a Mac? (with or without iWork)

  Hi all
  I don't have an idea what is a "PDF/X1a.
  I know how to create or convert PDF files on a mac, with the Preview app and the iWork.

  But a "PDF/X1a? What is c?

  Anyone know how to create or convert a "PDFX/X1a?

  Thanks to you all.

  Here is an explanation:

  https://www.prepressure.com/PDF/basics/PDFX-1A

  Frankly, I didn't know there are different "flavors". I create .pdf for years without knowing or worry about this. I just use an excerpt:

  

  Or, if you are in a document Pages (iWork as long that is not really exist anymore - there are separate applications: Pages, Numbers, Keynote), use the export as PDF option.

  Have never heard of someone that they were not able to read the PDF, I sent as an attachment.
