Hello, VicMware-

Get-View this error is because of the way you use the Select statement on line 3 when the first filling of the $Cluster variable.  You should be able to get this code to work if you leave off of the statement Select, so that line 3 is just:

...
## leave off the "| select -ExpandProperty Name" portion; just get the cluster
$Cluster = Get-Cluster
...

Then, when you perform the Get-view call, by default is the parameter - VIObject, since you spend a Cluster VIObject the cmdlet.  To be a little more explicit, you could include this setting, just so there's less/no confusion on the road when you resume the code and are decipher what is happening. As:

...
## specify the -VIObject parameter name, for clarity's sake
$Cluster = Get-View -VIObject $Cluster
$Cluster.ReconfigureComputeResource_Task($spec, $true)
...

In addition, copy the following code also assumes that you have only a 1 cluster (if you weren't already considering that).  If you are running in an environment with more than one cluster, you should probably use the name of the cluster desired as a parameter of the Get-Cluster line, or, if you are willing to take action on all clusters, use a Foreach-Object around these last lines, in order to call the method ReconigureComputeResource() on each object .NET view recovered for each cluster.

In any case, what to do for you?

  • Folder is a virtual computer in the use of Get-View

    All, I run a script to collect information on the virtual machines in the environment, but have not been able to figure out how to get the file to in the virtual machine is.  I know I could use a get - vm | Select name, file etc. but at the time wherever I have add a get - vm statement, I'll add a TON of execution time of the script.

    I'm getting to do a get-view command that limit the selection based on a subset of the clusters. I can easily do for objects of the VM, but when I use the same order type of the display does not work. Can anyone suggest a way to work for it. Here's the code that can better describe what I do:

    ------# Get VMs in the subset of the clusters * it works

    $Subset = 'Group 2', ' group 4 ", «group 6"»

    $VM = get-Cluster $Subset | Get - VM | Name sort

    $VMView = get-Cluster $Subset | Notice-EEG - ViewType VirtualMachine

    Thanks in advance,

    -Earl

    Hi Earl,

    The problem is that the cmdlet Get-View is not the - rental setting that is implicit, used by the Get - VM cmdlet in the pipeline to filter on clusters. You can change your code in the following way to get all views of the virtual machine to the specified cluster:

    $Subset = "Cluster2","Cluster 4","Cluster 6"
    $VMView = Get-Cluster $Subset | Get-VM | Get-View

  • Get menu command strings

    Recently, I need a way to integrate work plans in sight and learned that I can do it using the app.executeMenuCommand("fitall") . When I searched through the scripts of PDF files, I found no mention of this method.

    Then I have been aware of this question [JS] CS6 + executeMenuCommand2. There are lists of commands and some links in the responses. I have visited the links and this CS6 AI "app.executeMenuCommand" was the most enlightening to know where and how to get these commands. So I followed what the author.

    1. Create a new document
      1. Profile: Print
      2. Size: letter
    2. Create a new action game
      1. Name it "My Set".
    3. Create a new Action within the new series
      1. Name it "adjust the work plan.
    4. Insert the menu item
      1. Select view-> Fit artboard in the window.
      2. Click OK
    5. Record the Actions file
      1. File name is 'My Set.aia'

    When I look at the file "My Set.aia", I see that there are 3 parameters. The first is the menu command. The second is the name of the command. I don't know what is the third. The parameter values are in hexadecimal. Once I have become "666974696e" in ASCII, I get "polarized", the chain of menu command "fit the artboard in Window.

    /parameter-1 {
      /key 1769238125
      /showInPalette -1
      /type (ustring)
      /value [ 5
          666974696e
      ]
    }
    

    See the original and the files converted action.

    I tested with a few other commands, and it seems to work. Although I could not make it work to "fit in Window". Where to insert the menu in action item, select view-> Fit all in window does nothing. Type 'Fit all in window' and clicking on 'Find' also do not work. Gives the warning "no matching this name menu item was found. Why is this?

    Sigh. I wish an official documentation for app.executeMenuCommand () , and these commands were easier to access.

    Ok. It seems you are totally right.

    It is not possible to save this menu command in CS6 (64-bit) and not in CS6 (32 bit). Maybe a bug in this version of Illustrator.

  • PowerCLI: Get - view filters and OR conditions

    Hi all

    I'm little a beginner when it comes to tools from command-line and scripting in general, but I was playing around with PowerCLI and Get - view in particular and I wanted to understand if there was a way to specify multiple conditions and a 'GOLD' between them make in filters.
    Something like...

    Notice-EEG - ViewType VirtualMachine-filter @{name = "ABC123" or snapshot! = "} # does not work

    I took a glance at the documentation and I was unable to find a solution, but maybe a more experienced writer can confirm this?
    Thank you!

    I'm afraid, this is not possible, that all expressions in the filter hash table must comply.

    So, indeed, all expressions are AND-ed together.

    You can make a combination of two Get - sight lines of course.

    But I admit that this solution is not elegant or optimal.

  • Get-view SearchRoot when duplicate. MoRef exists

MoRef values.  Not sure how I can script around that.

    $ClusterList=@()
    $OutputFile="C:\Temp\looptesting.csv"

    The command

    Get-view ViewType - hostsystem-name of the Parent property

    Returns an array if you have more than one host. This means that you must do something like:

    (Get-view ViewType - hostsystem-name of the Parent property) [0]. MoRef

    or

    $x = get - View - ViewType hostsystem-property name, Parent
    $x [0]. MoRef

    to retrieve the first host MoRef.

  • Speed by using Get - VM vs Get-View

    Many VI Toolkit script I wrote end up needing to do something like this:

    Get-VM-name "vmname" | Get-View | etc.

    For some reason, I have to repeatedly Get-display to get something of value in the script.   For anyone who is located in a large enough knows that it's quite slow.   My colleague will me and said ' why don't you just jump the Get - VM and use Get - view directly?   You know it's a pretty clever idea, so I do.   I'm blown away at how much difference it is so I'll and the script I use time.

    Using the command Get-VM-name "vmname" | Get-view takes 1 minute and 37 seconds to run.  Ugh.

    Using the command Get-View - ViewType VirtualMachine-filter @{"Name" = "vmname"} takes... Wait what he

    Wait what he

    Wait what he

    5.12 seconds!

    Yes.  I don't do this.  The question I have for the VI Toolkit/Powershell assistants out there is WHY! ???

    The script I used for the test is attached.  Yes, it's not the world the better as its only my 3rd custom wrote the script to this day well I'll take recommendations contained in private messages or something different to make it better, nicer, faster, cooler, more powershell as.

    Hey, Ian,

    You can verify that you are using VI Toolkit 1.0 Update 1 (v.1.0.1). Between 1.0 and 1.0 1 update we have taken measures to improve the speed of Get - VM (limited). So if you're on upgrade-1.0.0 to 1.0.1 will relieve your problem a little bit.

    Basically, the reason why "Get - VM" is significantly slower than 'Get-View - ViewType VirtualMachine' is the virtual computer object is quite large and contains much more data than the view.

    A slow Get - VM is clearly a serious problem because it is by far the most frequently invoked cmdlet. If we look at ways to resolve the problem.

    One of the biggest steps we are taking is delegating the filtering on the server nickname. So, when you call Get - VM "vmname" the server would send a single virtual machine. This optimization is based on a feature which is new to VC 4.0. The bad news is that it will be a while before out us the version that has this optimization.

    Meanwhile, we are looking at ways to reduce the size of the VirtualMachine object by removing some of these objects nested such as VMGuest and virtual devices. The largest obstace of this change is the need for backward compatibility. If it's not completely simple, but I think that we will be able to find a compromise accepbable.

    Hello, tendonsie-

    Yes, you are right: If you change the type of object that you are using, and then later call what's going used probably not work with .

    However, another part of the power of Get - view: you have direct access to a representation of the object "full" vSphere - the View .NET VirtualMachine object, in this case.  So, you do no need another call to get the CpuReservationMhz - you can get it directly from the object VirtualMachine who have already recovered you.  An example of include these goods in the output (based on the example I gave first):

    Get-View -ViewType VirtualMachine -Property Name,Runtime.PowerState,Config.Hardware,Config.CpuAllocation.Reservation | Select-Object Name,    @{n="PowerState"; e={$_.Runtime.PowerState}},    @{n="NumCPU"; e={$_.Config.Hardware.NumCPU}},    @{n="MemoryGB"; e={$_.Config.Hardware.MemoryMB / 1KB}},    @{n="CpuReservationMhz"; e={$_.Config.CpuAllocation.Reservation}}
    

    You see the additional calculated property, CpuReservationMhz, here.  Now you don't need even have call the Get-VMResourceConfiguration cmdlet.

    Thus, work comes to discover what are the properties of the View .NET object that you have recovered.  And this work is supported by the vSphere API documentation, a link that is available to VMware vSphere Web Services SDK Documentation.  How is that?

Maybe you are looking for
