Script to Resize Citrix AppDisk on vSphere

I wrote this script to resize Citrix AppDisks which are running on vSphere.

The script finds the vCenter address and datastore that the AppDisk is located on, connects to vCenter and increases the size.

You need to have the XenApp / XenDesktop PowerShell cmdlets and Power CLI installed.

Disclaimer: Use this script at your own risk. All scripts should be tested on non-Production environments first.

We don’t have a code signing certificate yet so both script are available as .txt and .ps1 unsigned.

<# .SYNOPSIS Resizes Citrix AppDisk Running on VMware vSphere. .DESCRIPTION Script resizes a Citrix AppDisk running on vSphere. The script will query the AppDisk to get the vCenter address and connect to that address to resize the disk Script uses XenDesktop P VMware vCenter and Power CLI. .PARAMETER AppDiskName Name of the AppDisk to be renamed .PARAMETER NewAppDiskSize The new size of the AppDisk .PARAMETER vCenterUserName Username of an account with permission to connect to vCenter and resize the disk .PARAMETER vCenterPassword Password of the account to connect to vCenter. .PARAMETER AdminAddress Address of a XenApp / XenDesktop Controller being .EXAMPLE PS C:\Scripts > .\ -AppDiskName Finance -NewAppDiskSize 30 -vCenterUserName admin -vCenterPassword vmwarepassword -AdminAddress
-Path \\IREALVFIL001\XenAppScaling

Resize AppDisk called finance to 30GB
