Description

This article describes how to update the master image for Dedicated and Pooled MCS catalogs using PowerShell Software Development Kit (PowerShell SDK)

Background

The GUI option Update Machine is available only for the Pooled MCS catalogs. This option is not available for Dedicated MCS catalogs.

Instructions

Note: Changes applied to the master image of a Dedicated Catalog takes effect only for the new machines created from the image. These changes are not applied to the existing machines in the Catalog.

  1. Modify the master Virtual Machine or new virtual machine with the required changes.

  2. Take a snapshot of the modified virtual machine.

  3. Start PowerShell on Delivery Controller (Controller).

  4. Run command Add-PSSnapIn citrix*.

  5. Run command Get-ProvScheme.

    This displays a list of Provisioning Scheme(s) from the XenDesktop site. Make a note of the MasterImageVM entry.

    Example

    ProvisioningSchemeUid      : 2a01126c-0352-41e0-9603-9118120e15c3
ProvisioningSchemeName     : win7ded_anu
.
.
MasterImageVM        : XDHyp:\HostingUnits\anu\Anu- Win7.vm\existing.snapshot\Citrix_XD_win7-pooled.snapshot\Citrix_XD_win7-pooled.snapshot\sp1.snapshot\248813.snapshot
MasterImageVMDate          : 4/14/2011 6:01:21 PM
IdentityPoolUid            : 1d227066-f5ee-41b9-8a99-753e9d060e42
IdentityPoolName           : win7ded
HostingUnitUid             : d534c437-6c65-4659-97db-d6b86534685b
HostingUnitName            : anu
.
.
VMMetadata                 : {A, A, E, A...}

    Note: This preceding information is also required for reverting to the previous image.

  1. Run the following command to display the list of snapshots on the virtual machine:

    Get-ChildItem -Recurse -Path 'XDHyp:\hostingunits\%hostName%\%vmName%.vm'

    Example

    Get-ChildItem -Recurse -Path 'XDHyp:\hostingunits\anu\Anu-Win7.vm

    Where, hostname is anu and vmname is Anu-win7.

    Output

    PSPath         : Citrix.Host.Admin.V1\Citrix.Hypervisor::XDHyp:\hostingunits\anu\Anu- Win7.vm\existing.snapshot\Citrix_XD_win7-pooled.snapshot\Citrix_XD_win7- pooled.snapshot\sp1.snapshot\2505438.snapshot\afterupdate.snapshot
PSParentPath  : Citrix.Host.Admin.V1\Citrix.Hypervisor::XDHyp:\hostingunits\anu\Anu-
Win7.vm\existing.snapshot\Citrix_XD_win7-pooled.snapshot\Citrix_XD_win7- pooled.snapshot\sp1.snapshot\2505438.snapshot
PSChildName   : afterupdate.snapshot
.
.
ObjectPath     : /Anu-Win7.vm/existing.snapshot/Citrix_XD_win7-pooled.snapshot/Citrix_XD_win7-pooled.snapshot/sp1.snapshot/2505438.snapshot/afterupdate.snapshot
FullPath       : XDHyp:\hostingunits\anu\Anu-Win7.vm\existing.snapshot\Citrix_XD_win7- pooled.snapshot\Citrix_XD_win7- pooled.snapshot\sp1.snapshot\2505438.snapshot\afterupdate.snapshot
IsSymLink      : False
AdditionalData : {}

  1. Run the following command to publish the details of the master virtual machine:

    Publish-ProvMasterVmImage -ProvisioningSchemeName "%provisioningSchemeName%" -MasterImageVM "%templatePSPath%"

    Example

    Publish-ProvMasterVmImage -ProvisioningSchemeName win7ded_anu –masterimagevm XDHyp:\hostingunits\anu\Anu-Win7.vm\existing.snapshot\Citrix_XD_win7- pooled.snapshot\Citrix_XD_win7-pooled.snapshot\sp1.snapshot\2505438.snapshot\afterupdate.snapshot

    Where %provisioningSchemeName% is win7ded_anu and %templatePSPath% is XDHyp:\hostingunits\anu\Anu-Win7.vm\existing.snapshot\Citrix_XD_win7- pooled.snapshot\Citrix_XD_win7- pooled.snapshot\sp1.snapshot\2505438.snapshot\afterupdate.snapshot.

    The preceding command updates the master image and displays the result.
