Script to export vCenter roles / Permissions

I'm trying to find a script that will capture our vSphere vCenter roles and permissions hierarchy. I thought I found the perfect thing to:

http://www.virtu-al.NET/2009/06/15/vSphere-permissions-export-import-part-1

But I'm having real problems to make this work. I get the same kind of mistakes that other users on the site

The script works well, but I get continual errors along the lines of:

"You can not call a method on a null value expression.

C:\tmp\ExportRoles.ps1:85 char: 22

$node. "AppendChild (< < < < $tmp).

"You can not call a method on a null value expression.

C:\tmp\ExportRoles.ps1:85 char: 23

$node. ' SetAttribute (< < < < $name, $value).

"You can not call a method on a null value expression.

C:\tmp\ExportRoles.ps1:85 tank: 44

"$tmp = $global: vInventory.CreateElement (< < < < $nodeName).

Who performs a loop for a while, then I get an error like:

"Exception calling"AppendChild"with"1"or the arguments:"Object reference not set to an instance of an object." .

C:\tmp\ExportRoles.ps1:81 char: 22

$node. AppendChild (< < < < $tmp)

When doing the fix as indicated by one of the users on the modification of the "global" part, I get the same erros but with a new fundraiser:

' Exception calling 'CreateElement' with '1' or the arguments: "the local name for elements or attributes cannot be null or an empty string." '

C:\tmp\ExportRoles.ps1:80 tank: 37

$tmp = $vInventory.CreateElement (< < < < $nodeName)

The script creates the xml file filled with descriptors, it is simply not filling with one of my roles or permissions. I removed most of the roles stocks and created new roles from scratch.

I am using vCenter 4.0U1 build 208111 and 4.0.1 - 208462 PowerCli

Any ideas? Or people me for a script that will capture this point. I especially like the fact that it is pumped on XML as my intention is to use the process of generation automated for our environment. I'm pretty green in Powershell, I copied this verbatim script so if there is something Yes, I should do please shout. I guess that's not enumarting the values of the Manager, but I don't know where to insert a "Write-Host" step at the exit of the value on the display to check where it's down once again any help with this would be appreciated.

Long live the people.

This is one of my old script that apparently has had some problems in PowerShell v2.

Attached a new version.

Can you check if this works for you?

  • Vcenter roles and permissions on files to export

    Hello

    I use the script to Gabe at low cost disaster recovery for export permanent folder, but when I checked to see if it exports all folders in my vCenter there seems to be some missing files... At first I thought that maybe the account I used to export was the role of administrator or role is has not spread downwards for missing files, but after checking, it was not the case.

    Code:

    --------------------------

    Function Get roles

    {

    Begin {}

    $authMgr = get-View Manager

    $report = @)

    }

    {In process

    $ret | Add-Member-Type noteproperty-Name 'Privilège' - value $role.privilege

    $report += $ret

    }

    }

    {End}

    return $report

    }

    }

    $ret | Add-Member-Type noteproperty-Name 'Role' - value $roleHash [$perm. RoleId]

    $report += $ret

    {End}

    return $report

    [XML] $vInventory = ' < inventory > < roles / > < permissions / > < / inventory >.

    # Roles

    $XMLRoles = get-XmlNode "inventory/roles".

    Get-roles. where {-not $_.} System} | % {

    $XMLRole = new-XmlNode $XMLRoles 'Role '.

    }

    $vInventory.Save ($OutFile)

    Depending on how deeply nested and common names are and would need to be analyzed, but essentially, Yes. If you re-create your folder structure to match your original vCenter, then you can apply the permissions in the appropriate folders and as long as it spread is set accordingly, it must inherit for sub folders similar to how they were put in the original vCenter.

    One caveat is that you must export both custom roles/privileges.

  • Need a little help. Script to export the single document for different types of files.

    Hey guys, I'm new to scripting. have looked everywhere but cannot find an answer to this, I'm sure it's pretty simple


    At work we export logos all the time in a few different formats for the clients.
    I looked in the script as a way to automate the process.

    So far, I thought a little script to export my Illustrator formats document... now I need to be able to export this document even outside as a res low and high PNG, low and high res JPEG, EPS, PDF and TIFF etc.
    I have scripts to do all these separately but just need to know how to put it all in a single script I can do all at once

    Here is an example of my two different scripts to export PNG. I just need to know how string together so I can add all of the formats without breaking it.

    function savePNG() {}
    var destFolder = Folder.selectDialog ("select the folder to export the PNG files to :');")
    If {(destFolder)
    If (app.documents.length > 0) {}
    var Nomdoc = app.activeDocument.name.match(/^.*[^.ai]/i);
    var destFile = new file (destFolder + ' /' + Nomdoc + "-HR.png");
    if(destFile == null) {return ;}
    var doc = app.activeDocument;
    var artRect = doc.artboards [0] .artboardRect;
    var exportOptions = new ImageCaptureOptions;
    exportOptions.resolution = 300;
    exportOptions.antiAliasing = true;
    exportOptions.transparency = true;
    doc.imageCapture (destFile, artRect, exportOptions);
    }
    }
    }
    savePNG();

    and here is the version low resolution

    function savePNG() {}
    var destFolder = Folder.selectDialog ("select the folder to export the PNG files to :');")
    If {(destFolder)
    If (app.documents.length > 0) {}
    var Nomdoc = app.activeDocument.name.match(/^.*[^.ai]/i);
    var destFile = new file (destFolder + ' /' + Nomdoc + "-LR.png");
    if(destFile == null) {return ;}
    var doc = app.activeDocument;
    var artRect = doc.artboards [0] .artboardRect;
    var exportOptions = new ImageCaptureOptions;
    exportOptions.resolution = 72;
    exportOptions.antiAliasing = true;
    exportOptions.transparency = true;
    doc.imageCapture (destFile, artRect, exportOptions);
    }
    }
    }
    savePNG();

    Thanks for any advice you can give!

    Oh, you want to perform two functions, one after another at the same time? then just name with different names and perform one function after another, if all files will be saved in the same folder, the argument selectDialog move method on each of your functions to don't do only once.

    function savePNG_HR(){
        var destFolder = Folder.selectDialog('Select the folder to export the PNG files to:');
        if (destFolder) {
            if(app.documents.length > 0){
                var docName = app.activeDocument.name.match(/^.*[^.ai]/i);
                var destFile = new File(destFolder + '/' + docName + " - HR.png");
                if(destFile == null){return;}
                var doc = app.activeDocument;
                var artRect = doc.artboards[0].artboardRect;
                var exportOptions = new ImageCaptureOptions;
                exportOptions.resolution = 300;
                exportOptions.antiAliasing = true;
                exportOptions.transparency = true;
                doc.imageCapture(destFile, artRect, exportOptions);
            }
        }
    }

  • Script to export the VC roles/Permissions/objects

    I need a script to the list of all the roles in VC, users/groups assigned to the role, and the role object is assigned to. I want only the list of objects that have a role assigned to them. I would also like to be able to export this info into a csv file if possible. If anyone has a pre-made script that can do it, it would be very useful. I was looking for some sort of get-permission or the cmdlet get-vmpermission to achieve this, but cant seem to find anything. Any help would be great.

    Thank you

    Jason

    Get permissions is a filter I wrote, see the script in the use of role identifier.

    Again not in this thread.

    The line example I gave was just a new version of the last line of the script in the use of role ID to show how to export the result to a CSV file.

    The parameter - Useculture is new in PowerShell v2. Sorry should have left this.

    I use it because it solves the problem we had in PS v1 with the separator.

    By default, the separator is a comma, but in our locale, it is defined as the semicolon.

    Without the parameter - Useculture the Export-Csv cmdlet always uses a comma, with this setting, need the separator defined in the regional settings.

    Your last question, Yes, you can limit the scope of the Get-Onventory cmdlet with the - Location parameter.

    If, for example, only wanted a report for a specific data center, you can do

    Get-Inventory -Location (Get-Datacenter ) | Get-Permissions | Export-Csv -Path "C:\permissions.csv" -NoTypeInformation
    
  • How can I save vCenter roles and permissions

    As you know the permissions and roles of vCenter are stored locally in a database of ADAM, even when the main inventory SQL server database is on a different system.   I backup my separately from SQL server database but do not save the local database of ADAM.  What is the best way to save the ADAM database if there are no backups at the hypervisor level of vCenter server? vCenter server is virtualized and unfortunately only in guest-backup agents are allowed by this company, no backups of VMDK.  Solutions of VADP are not allowed.   Thank you!

    This information is part of the VCDB as well, and if you save the VCDB you will be covered.  However, you can manually save ADAM if you wish.

  • vs vCenter host permissions

    We run 5.0 ESXi and vCenter and I noticed a problem the other day when one of my colleagues tried to connect to one of our hosts directly using the vSphere Client.  We have some ad groups that we have assigned various permissions in vCenter and all works fine when connected to vCenter through the client, but none of the roles or permissions show up if we try and connect directly to the host.  It's design or something do not propagate properly?

    This is normal. The permissions are stored in the database of the vCenter server and applied to the objects in the inventory. vCenter Server connects to the host by using the 'vpxuser' to perform tasks, but only allows each user to vCenter server tasks that he is allowed to.

  • Roles, permissions - DataCenter, file, Cluster, host Layout - best Practices\How-to

    Have a little problem with permissions and roles. I'm sure it will be an easy one for those of you with more experience of working with roles. I hope that my layout organization made with quote boxes is readable.

    The Organization has just spun a new host ESXi 4 for developers and added in vCenter. Developers want to use the vSphere Client\VIC to manage the ESX Server. They need rights to create virtual machines, remove VMs, clone VMs, VMs potential power. However, we don't want them to be able to reach production.

    According to the diagram below, the new host of development, labeled as "HostC (autonomous DEVELOPMENT host)", is located under "Data Center-City-2", who also owns the production ESX clusters. " And obviously I don't want developers having rights on production groups.

    Lets say I have create a role called 'HostC Dev Sandbox Rights', add users and assign directly to "HostC" below. This role contains the VM 'create' right, however when I run the wizard Creation of VM of HostC as a member of the role the vSphere Client tells me this task requires rights create VM on the level of data center! But given these developers to create VMS access on the data center would give them rights to create virtual machines in the poles of Production! Which is obviously a problem.

    I can't believe that our need to give these rights to ONLY one host in a DataCenter is rare. I don't know that there is a misunderstanding on my part of how to configure VMware roles for best practices.

    Anyone with more expirence on VMware roles ready to help me on this one? Thanks in advance!

    You can apply permissions directly to the data store.  I didn't need to go further than the clusters in our environment, but what really works for you is to place data warehouses in folders for storage.  Have the records be the names of your groups hosts and clusters.  Then place the warehouses of data for each cluster in the corresponding folder.  Then, just apply permissions for the data on the record instead of warehouses in each individual data store.  Off topic a little, but a records of something in the store of data discovered lack is the function of "views of storage" and I put a future application.

    Yes, if you set permissision to the view of the data store the user can turn opinion and see.  Extensive your permissions framework tests is guaranteed before pushing users.  Looks like you are already doing.
