Verify Citrx HostedMachineID with VmWare Hypervisor

Sometimes the HostedMachineID of Citrix does not match that of VmWare. This is often the case when cloning or moving machines. In Citrix Studio you will see the Powerstate of this machines as unknow and you can’t do any VM actions like reboot in the console.

With this script snippet it can be checked. To do this the variable “Broker” must be adjusted in the Script and the PowerCli and CitrixModule (BrokerSnapIn) must be loaded. Furthermore, the connection to the vCenter must be initiated via “Connect-VIServer vCName“.

Now that the machines have been read out, the connections can be fixed.

vCenter Cert thumbprint update:

The letters in SSL-Thumbprint must be uppercase.

In this blog the problem is also discussed in detail:

Scriptblock to check PVS Connection

On the fly, I found no way to check which PVS servers & service are online. This is especially important if I want to issue PVS commands from Remote / Orchestrated. Enclosed I have made a small script block to check this. It is certainly not the best way, but it works. One possibility would be to retrieve the status of the PVS-services, but it is unclear whether one can actually connect to the servers trough PVS commands.

Delete Citrix Worker from Studio and vCenter

With this script one or more servers can be deleted from the Citrix DeliveryController (Citrix Studio) and from the ESXi/vCenter.

To use The Script some variables and values need to be adjusted like the name of the Citrix DeliveryController and vCenter.
Vmware (PowerCLI) and Citrix (SDK) powershellmodules need to be installed.

This only works if the VM name is identical to the Worker Server DNS name. If this is the case, the following string can be deleted in the script [-replace “.FQDN.address”,””]

In my case, the name of the VM is only the “hostname” of the machine and not the DNSname. So the script removes the FQDN name, in order to use the script successfully, this must also be adjusted.

Backup & Restore Citrix Storefront Configuration with Powershell

Backup

Ensure you’re running Powershell as Administrator and you loaded the StoreFront Powershell Modules:

Export STF Configuration

The IIS settings will be not saved. For example, IIS bindings to the default web site or HTTP Redirect entries that were made, will not be imported when you restore the backup ZipFile.

You can also take an IIS Configuration Backup.

Unfortunately, not all settings will be exported from the IIS here either…
Therefore I recommend to make a backup of the server (VM Snapshot or similar) another method is to keep an installation documentation about the manual IIS configuration and to recheck the config after a configrestore.

Restore

Citrix Config Restore:

Afterwards you have to propagate the Storefront Configuration.


Restore IIS Config:

To restore IIS Configuration ensure you define the variable “$a” in the script above with the name of the Backupfolder.

You can find those Folders under “C:\WINDOWS\System32\inetsrv\backup”

IIS Custom settings are not synchronized with Storefront Propagate function. The restore must be done on every storefront server.
