Removes a provisioning scheme

Syntax

Remove-ProvScheme [-ProvisioningSchemeName] <String> [-ForgetVM] [-LoggingId <Guid>] [-BearerToken <String>] [-VirtualSiteId <String>] [-AdminAddress <String>] [<CommonParameters>]

Remove-ProvScheme -ProvisioningSchemeUid <Guid> [-ForgetVM] [-LoggingId <Guid>] [-BearerToken <String>] [-VirtualSiteId <String>] [-AdminAddress <String>] [<CommonParameters>]
<!--NeedCopy-->

Detailed Description

Provides the ability to remove a provisioning Scheme. The provisioning scheme must not contain any VMs unless the ‘ForgetVM’ option is specified.

If ‘ForgetVM’ is not specified, a cmdlet task is created that runs in the background to remove the hard disk copies that have been created for the provisioning scheme in hypervisor storage. Use the Get-ProvTask command to monitor the progress of this task.

Parameters

Name Description Required? Pipeline Input Default Value
ProvisioningSchemeName The name of the provisioning scheme to be removed. true true (ByPropertyName)  
ProvisioningSchemeUid The unique identifier for the provisioning scheme to be removed. true true (ByPropertyName)  
ForgetVM Indicates whether or not the VMs in the provisioning scheme should be left in the hypervisor and only the data held in the Machine Creation Services removed. If this is specified, it is up to the administrator of the hypervisor to remove the VMs and hard disk images using the tools provided by the hypervisor itself. false false  
LoggingId Specifies the identifier of the high-level operation this cmdlet call forms a part of. Citrix Studio and Director typically create high-level operations. PowerShell scripts can also wrap a series of cmdlet calls in a high-level operation by way of the Start-LogHighLevelOperation and Stop-LogHighLevelOperation cmdlets. false false  
BearerToken Specifies the bearer token assigned to the calling user false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  
AdminAddress Specifies the address of a XenDesktop controller that the PowerShell snap-in connects to. You can provide this as a host name or an IP address. false false LocalHost. Once a value is provided by any cmdlet, this value becomes the default.

Input Type

Return Values

Citrix.Machinecreation.Sdk.Provisioningscheme

This object provides details of the provisioning scheme and contains the following information:
ProvisioningSchemeUid
The unique identifier for the provisioning scheme.
ProvisioningSchemeName
The name of the provisioning scheme.
CpuCount
The number of processors that VMs will be created with when using this scheme.
MemoryMB
The maximum amount of memory that VMs will be created with when using this scheme.
MasterImageVM
The path within the hosting unit provider to the VM or snapshot of which the scheme is currently using a copy.
MasterImageVMDate
The date and time that the copy of the VM image was made for the scheme.
IdentityPoolUid
The unique identifier of the identity pool (from the ADIdentity PowerShell snap-in) that the scheme uses.
IdentityPoolName
The name of the identity pool (from the ADIdentity PowerShell snap-in) that the scheme uses.
HostingUnitUid
The unique identifier of the hosting unit (from the Hosting Unit PowerShell snap-in) that the new provisioning scheme will use.
HostingUnitName
The name of the hosting unit (from the hosting unit PowerShell snap-in) that the new provisioning scheme will use.
CleanOnBoot
Indicates whether the VMs created are to be reset to a clean state on each boot.
TaskId
The identifier of any current task that is running for the provisioning scheme.

Notes

If the hosting unit referenced by the provisioning scheme no longer exists (i.e. it has been removed using the Hosting Unit PowerShell snap-in), the provisioning scheme data is deleted from the database without errors. However, the hard disks associated with the provisioning scheme cannot be removed and remain in the hypervisor.
In the case of failure, the following errors can result.
Error Codes
———–
IllegalParameter
One or more parameters are illegal or are not specified.
ProvisioningSchemeNotFound
The specified provisioning scheme could not be located.
UnableToRemoveProvisioningSchemeDueToAssociatedVM
The provisioning scheme contained VMs and the ‘ForgetVM’ parameter was not specified.
DatabaseError
An error occurred in the service while attempting a database operation.
DatabaseNotConfigured
The operation could not be completed because the database for the service is not configured.
ServiceStatusInvalidDb
An error occurred in the service while attempting a database operation - communication with the database failed for
for various reasons.
CommunicationError

PermissionDenied
The user does not have administrative rights to perform this operation.
ConfigurationLoggingError
The operation could not be performed because of a configuration logging error
ExceptionThrown
An unexpected error occurred. To locate more details, see the Windows event logs on the controller being used or examine the XenDesktop logs.
The cmdlet is associated with a task of type DisusedImageCleanUp, and while active will move through the following operations (CurrentOperation field)
Running
