Parameters

-VMName

List of VM names that will be removed from the provisioning scheme.

Type: String[]
Position: Named
Default value: None
Required: True
Accept pipeline input: True (ByPropertyName, ByValue)
Accept wildcard characters: False

-ProvisioningSchemeName

The name of the provisioning scheme from which VMs will be removed.

Type: String
Position: 2
Default value: None
Required: True
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ProvisioningSchemeUid

The unique identifier of the provisioning scheme from which VMs will be removed.

Type: Guid
Position: 2
Default value: None
Required: True
Accept pipeline input: False
Accept wildcard characters: False

-PurgeDBOnly

If this option is specified, this command will only remove VM objects from the Machine Creation Services database; however, the VMs and hard disk copies still remain in the hypervisor. The hypervisor administrator can remove the VMs and hard disk images using the tools provided by the hypervisor itself. If not specified, the VMs and hard disk copies are also removed from hypervisor storage. This parameter is exclusive with “ForgetVM”.

Type: SwitchParameter
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False
Introduced in: Citrix Virtual Apps and Desktop 7 2212

-ForgetVM

If this option is specified, this command will only remove VM objects from the Machine Creation Services database; however, the VMs and hard disk copies still remain in the hypervisor after removing VMs’ citrix tags/identifiers. The hypervisor administrator can remove the VMs and hard disk images using the tools provided by the hypervisor itself. If not specified, the VMs and hard disk copies are also removed from hypervisor storage. This parameter is only applied to persistent VMs and exclusive with “PurgeDBOnly”.

Type: SwitchParameter
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-RunAsynchronously

Indicates whether the command returns before it completes. If this is specified, the command returns an identifier for the task that was created. This task can be monitored using the Get-ProvTask command.

Type: SwitchParameter
Position: Named
Default value: False
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-PurgeJobOnSuccess

Indicates that the task history is removed from the database when the task completes. This cannot be specified for tasks that run asynchronously.

Type: SwitchParameter
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: 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.

Type: Guid
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

CitrixCommonParameters

This cmdlet supports the common Citrix parameters: -AdminAddress, -AdminClientIP, -BearerToken, -TraceParent, -TraceState and -VirtualSiteId. For more information, see about_CitrixCommonParameters.

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

Inputs

Citrix.MachineCreation.Sdk.ProvisionedVirtualMachine

You can pipe an object containing parameters called ‘VMName’ and ‘ProvisioningSchemeName’ to Remove-ProvVM.

Status <string>

Where in its lifecycle the task is.

PurgeDBOnly <bool>

Whether the named VMs are only removed from the Machine Creation Service database, but still remain in the hypervisor.

ForgetVm <bool>

Whether the named VMs are only removed from the Machine Creation Service database, but still remain in the hypervisor after removing VMs’ citrix tags/identifiers.

RemovedVirtualMachines <Citrix.DesktopUpdateManager.SDK.VirtualMachineCreation[]>

Notes

The cmdlet is associated with a task of type RemoveVirtualMachine, and while active will move through the following operations (CurrentOperation field)

ValidatingInputs

RemovingVirtualMachines

Only one long-running task for each provisioning scheme can be processed at a time.

This task still operates if the hosting unit or VMs in the hypervisor are missing. This removes the data from the Citrix Machine Creation Services, but the VMs remain in the hypervisor.

In the case of failure, the following errors can result.

Error Codes


ProvisioningSchemeNotFound

The specified provisioning scheme could not be located.

ProvisioningSchemeNotReady

The specified provisioning scheme is not in Ready state.

JobCreationFailed

The requested task could not be started.

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.

WorkflowHostUnavailable

The task could not be started because the database connection is inactive.

CommunicationError

An error occurred while communicating with the service.

InvalidParameterCombination

Both PurgeJobOnSuccess and RunAsynchronously were specified. When running asynchronously, the cmdlet terminates before the job does, so it cannot clean up the completed job.

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. For more details, see the Windows event logs on the controller being used or Citrix Virtual Apps and Desktops logs.
