Description

Provides the ability to remove a provisioning Scheme. The provisioning scheme must not contain any VMs unless the ‘ForgetVM’ or ‘PurgeDBOnly’ option is specified. If either option is specified, all associated provisioned snapshots will be deleted. Use the Get-ProvTask command to monitor the progress of this task.

Examples

EXAMPLE 1

Remove the empty provisioning scheme by name.

Remove-ProvScheme -ProvisioningSchemeName $provScheme.ProvisioningSchemeName
<!--NeedCopy-->

EXAMPLE 2

Deletes provisioning scheme ‘Catalog-1’ data from the Citrix site database

Get-ProvScheme -ProvisioningSchemeName Catalog-1 | Remove-ProvScheme -PurgeDBOnly

EXAMPLE 3

Removes all the Citrix-assigned identifiers(like tags or custom-attributes) on provisioning scheme, VMs and their related resources from hypervisor and also the deletes provisioning scheme ‘Catalog-1’ data from the Citrix site database.

Parameters

-ProvisioningSchemeName

The name of the provisioning scheme to 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 to be removed.

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

-PurgeDBOnly

If this option is specified, this command will only remove the provisioning scheme data from the Citrix site database. However, the VMs and related resources created in the provisioning scheme still remain in the hypervisor. The hypervisor administrator can remove the VMs and hard disk images using the tools provided by the hypervisor itself. This option can also be used when you are no longer able to contact the hypervisor and you want to remove the provisioning scheme from Citrix site database. This parameter cannot be used with “ForgetVM”.

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

-ForgetVM

If this option is specified, this command will remove the provisioning scheme data from the Citrix site database and also delete Citrix-assigned identifiers(like tags or custom-attributes) on provisioning scheme, VMs and their related resources from hypervisor. However, the VMs and related resources created in the provisioning scheme still remain in the hypervisor after removing identifiers(like tags or custom-attributes). The hypervisor administrator can remove the VMs and hard disk images using the tools provided by the hypervisor itself. This parameter is only applied to persistent VMs and cannot be used 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.

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

If the hosting unit referenced by the provisioning scheme no longer exists (that is, 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’ or ‘PurgeDBOnly’ parameter was not specified.

DatabaseError

An error occurred in the service while attempting a database operation.
