Detailed Description

Provides the ability to update the hard disk image used to provision virtual machines. If the provisioning scheme is a ‘CleanOnBoot’ type, then the next time that virtual machines are started, their hard disks are updated to this new image. Regardless of the ‘CleanOnBoot’ type, all new virtual machines created after this command will use this new hard disk image.

A background task will be created to remove the old hard disk copies. You can locate and monitor this task using the Get-ProvTask cmdlet.

A snapshot or VM template is used rather than a VM, so that the content of the hard disk for the provisioning scheme can be easily determined.

As the snapshot or VM template are specified using a path into the Citrix Host Service PowerShell Provider, the Citrix Host Service PowerShell snap-in must also be loaded for this cmdlet to be used.

The previous hard disk image path is stored into the history (see Get-ProvSchemeMasterVMImageHistory). The data stored in the history allows for a rollback to be undertaken, to revert to the previous hard disk image if required.


Name Description Required? Pipeline Input Default Value
ProvisioningSchemeName The provisioning scheme to which the hard disk image should be updated. true true (ByPropertyName)  
PreparedImageDefinitionName The name for the image definition used for the provisioning scheme. true false  
PreparedImageVersionNumber The version number for the image version used for the provisioning scheme. true false  
ProvisioningSchemeUid The provisioning uid identifier to which the hard disk image should be updated. true false  
PreparedImageVersionUid The identifier for the image definition used for the provisioning scheme. true false  
RunAsynchronously Indicates whether or not the cmdlet should return before it is complete. If specified, the command returns an identifier for the task that was created. You can monitor this task using the get-ProvTask cmdlet. false false false
PurgeJobOnSuccess Indicates that the task history will be removed from the database once the task has finished. This cannot be specified for tasks that are run asynchronously. false false false
DoNotStoreOldImage Indicates that the current image should not be added to the image history list for the provisioning scheme. This is useful when rolling back to a previous image. 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  
AdminClientIP Specifies the Client IP of the calling user false false  
TraceParent Specifies the trace parent assigned for internal diagnostic tracing use false false  
TraceState Specifies the trace state assigned for internal diagnostic tracing user false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  
AdminAddress The address of a Citrix Virtual Apps and Desktops controller the PowerShell snap-in will connect 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.

In the case of failure, the following errors can result.
Error Codes
The requested task could not be started.
An error occurred in the service while attempting a database operation.
The operation could not be completed because the database for the service is not configured.
An error occurred in the service while attempting a database operation - communication with the database failed for
