-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”.

| 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 |

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.

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.
