Citrix Studio access during an outage


When you have a Citrix Virtual Apps and Desktop site with multiple zones, all zones are not created equally and this can affect Citrix Studio access during an outage. Citrix Virtual Apps and Desktops uses a concept of Primary and satellite zones. When a failure occurs within the Primary zone meaning that either all the delivery controllers are down or disconnected from the SQL databases Citrix Studio becomes unavailable.

While restoring the primary zone controllers to a working state should be the main concentration point the environment may have been designed to be highly available so the satellite sites can continue to run and potentially require business as usual type access.

Luckily there is a simple powershell command that you can run on one of the surviving satellite zone controllers in order to reclassify the satellite zone as primary and reinstate Studio access.

Set-ConfigSite -PrimaryZone “SataliteZoneName”

The Set-ConfigSite command also includes quite a few other capabilities that are worth exploring more details can be found here.

As long as you remember to run it again to reverse the change back to the original Primary Zone when it is healthy again.
