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.

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.ProvisionedSnapshot

You can pipe an object containing parameters called ‘VMName’, ‘ProvisioningSchemeName’, and optionally ‘SnapshotName’ to Remove-ProvVMSnapshot.

Outputs

Guid

When the RunAsynchronously identifier is specified, this GUID is returned and provides the task identifier.

System.Management.Automation.PSCustomObject

This object provides details of the task that was run and contains the following information:

TaskId <Guid>

The identifier for the task that was performed.

Active <bool>

Indicates whether the task is still processing or is complete.

Host <string>

The name of the host on which the task is running or was run.

DateStarted <DateTime>

The date and time when the task was started.

Metadata <Citrix.MachineCreation.Sdk.Metadata[]>

The list of metadata stored for the task. For new tasks, this is empty until metadata is added.

CurrentOperation <string>

Operation specific phase of the overall “Running” task state.

TaskProgress <double>

The progress of the task 0-100%.

LastUpdateTime <DateTime>

The date and time of the last task status update.

ActiveElapsedTime <int>

Number of seconds the task has taken for active execution.

DateFinished <DateTime>

The date and time when the task was completed.

TerminatingError < Citrix.Fma.Sdk.ServiceCore.CommonCmdlets.TaskterminatingError>

Diagnostic information if the task completely fails.

Type <Citrix.XDInterServiceTypes.JobType>

The type of task. For new Remove-ProvVMSnapshot tasks, this is always “RemoveProvisionedSnapshot”.

Status <string>

Where in its lifecycle the task is.

StatusAdditionalInformation <string>

Extra information about the Status.

RemovedSnapshots <Citrix.DesktopUpdateManager.SDK.ProvisionedSnapshot[]>

Object array of removed snapshots summary information. The object properties are:

CreationDate <DateTime>

The date and time when the snapshot was created.

Domain <string>

The Domain of the AD computer account that the VM is using.

ProvisioningSchemeName <string>

The name of the provisioning scheme associated with the snapshot.

ProvisioningSchemeUid <Guid>

The unique identifier of the provisioning scheme associated with the snapshot.

ProvisioningSchemeVersion <int>

The version of the provisioning scheme used by the associated VM at the time of snapshot creation.

ProvVMConfigurationVersion <int>

The version of the custom configuration used by the associated VM at the time of snapshot creation.

SnapshotUid <Guid>

The unique identifier of the provisioned snapshot.

HypervisorID<string>

The hypervisor identifier of the provisioned snapshot.

SnapshotName <string>

The name of the provisioned snapshot.

VMId <string>

The identifier for the associated VM in the hypervisor.

VMName <string>

The name of the associated VM in the hypervisor.

HostingUnitUid <Guid>

The unique identifier of the hosting unit that was used to create the associated VM.

HypervisorConnectionUid <Guid>

The unique identifier of the hypervisor connection that was used to create the associated VM.

DeletionProtection <bool>

Flag indicating if snapshot requires explicit deletion.

FailedSnapshots <Citrix.DesktopUpdateManager.SDK.ProvisionedSnapshot[]>

See RemovedVirtualMachines for details of the object parameters.

TaskState <Citrix.DesktopUpdateManager.SDK.ProvisionVMState>

The state of the task. This can be any of the following:

Processing

Indicates that the task is in its initial state.

LocatingResources

Indicates that the task is locating information from other services.

HostingUnitNotFound

Indicates that the required hosting unit could not be located.

ProvisioningSchemeNotFound

Indicates that the required provisioning scheme could not be located.

Provisioning

Indicates that the task is at the provisioning stage.

IdentityPoolNotFound

Indicates that the required identity pool could not be located.

TaskAlreadyRunningForProvisioningScheme

Indicates that the provisioning scheme already has another task running.

Finalizing

Indicates that the task is finalizing.

Finished

Indicates that the task is complete.

FinishedWithErrors

Indicates that the task is complete but there were errors. Specific details of errors are included with each failed virtual machine.

Removing

Indicates that the task is removing virtual machines from the hypervisor.

Failed

Job failed for reasons specified in TaskStateInformation.

Canceled

Indicates that the task was stopped by user intervention (using Stop-ProvTask).

TaskStateInformation <string>

Provides more detailed information about the current task state.

WorkflowStatus <System.Workflow.Runtime.WorkflowStatus>

Indicates the status of the workflow that is used to process the task.

TaskExpectedCompletion <DateTime>

The date and time at which the task is expected to complete.

Notes

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

ValidatingInputs

RemovingSnapshots

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

This task still operates if the hosting unit or snapshots 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

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 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.
