The ultimate Citrix XenDesktop 7.x internals cheat sheet!
What if you have to shut down the entire Citrix infrastructure for hardware maintenance, software upgrades or "the unknown"? I developed this plan for "the unknown" and hope that it helps you as well. This article explains how to properly shut down and start your ENTIRE Citrix environment.

ADCs have gained traction within the last decade, largely due to increased demand for legacy load balancing appliances to handle more advanced application delivery requirements and improve application performance.

After several days of searching and hunting for limited documentation, I wanted to share this guide to hopefully save someone the hassle of trying to figure this out on their own.
I have tested this on Xendesktop 7.1 and PS 4.5 running simultaneously off of the same web interface server. So the old and the new works together easily.

For this article the following pieces of software were used -

Ubuntu 12.04 lts x64 - Download Here
Citrix Web Interface 5.4 for Java Application servers - Download here
Putty to ssh into the server - Download Here
Winscp to transfer files to/from the server - Download Here

Starting off there are tons of guides on how to install Ubuntu server and set a static ip with dns resolution. Make sure when you are installing it you install with the below options. This article assumes you have used winscp, putty, and linux shell editors like nano and vi before.

If you know how to install Apache on its own, I would recommend doing it that way. For ease of use we select the LAMP server option in this document.

Install optionsThis will install the core OS with all the software needed to make this work.

Once the os is up and running.

I like to make sure a few things are installed to help troubleshoot…

Hi Brian,

Does this guide works for Citrix NetScaler VPX for ESX 11.0 Build 64.34 appliance as well ?

Yes.  VPX.

With that said, be conscious of the throughput.  Regardless of model HTTP Compression is
Up to 0.75 Gbps for all VPX models

Before I go to far, let's explain HA (High Availability) and why you should consider it.  High availability is the mechanism used to provide redundancy to any service at the same site and appears as a single service to the users of that service.  As opposed to DR (Disaster Recovery) which provides a mechanism used to provide redundancy to any service at disparate sites and are mirrors of the same services.  HA is needed incase of component failure.  In the case of this article, we are looking at a netscaler failure, an uplink failure the netscaler depends on, a hard drive failure, or any other failure that may make a netscaler inoperable.  In this case, having a HA pair a second netscaler that stands "idle" will detect that its peer has failed and take over the load balancing duties automatically.  By doing this, it ensures higher availability to the users (hence the HA name) and minimizes impact.  In turn it gives you as the admin breathing room to repair the inoperable node without everyone on you to get services working again.  I hope this explains, although briefly, what HA is and why using HA with a netscaler would be beneficial to you.

When setting up a netscaler HA pair, there are a few things to consider:

1) you don't have to have the devices directly linked to one another like some devices might need to be for HA to work
2) hardware platforms must be identical.  Meaning you can't have a Netscaler 22500 and a 11500 be peers
3) It is not 100% necessary to have …

yes, I've done this many times before.  Other than what is on citrix.com edocs I have ZERO images.  I have configs (of which I'm not allowed to share), that's it.  This article was not even proofread, this was purely from memory.  I'm sure others have more time which is why they can do images as well.  this article writing actually constituted about 90-95% of my available time I could dedicate to EE this month.  I just don't have time.  If you are wanting to be a stickler about images though, that is fine.  I will stop writing articles.

I am writing this article to help others who have been trying to find clear answers on how to drain a service in Citrix Netscaler 9.3 or greater. The content in this article is from both my hands on experience and from Citrix support

When you need to take a server out of service for maintenance, I recommend opening a SSH session to the Netscaler and typing in the command: stat service to list the number of connections each service hosted by the server has open. The service name needs to be the name listed for the service on the Netscaler, for example: stat service WebServer-http.

You can find the number of connections used by the service by looking at the current client connections and current server connection lines. This is good information to have when you start so you know how many connections are present. Below is a screen shot of what the output from the stat service command would look like.

In the Netsclaer GUI, open the service. By default the “Down State Flush” is selected. What this does is if you disable the service without using a Graceful shutdown, all sessions using the service will be dropped instantly and the service will be marked “Out Of Service”. Citrix support recommends leaving this at its default setting of enabled. Click the Disable button; this will then open a window that will allow you to select Graceful shutdown and Wait Time value in seconds.

When you select Graceful shutdown, all current …
