SOAP-ENV:Client Unknown method "{urn:iControl:ITCMSystem/SystemInfo}:get_product_info"

Matt is correct, for v9 and above there was a change in the API and it seems (from your use of the ITCM* namespaces) that you are still using the v4.x APIs. If you go into the iControl API reference

you can browse down into the interfaces and methods and you will see an "Introduced" attribute to each method. This will indicate the first BIG-IP version that the method was added in. So, if you look at the System.SystemInfo.get_system_information() method you'll see that it was introduced in "BIG-IP_v9.0" which means it's available in every release including and after BIG-IP v9.0.

 

BTW, which language are you developing your iControl application with? We have some helper libraries for Java, .Net, and Python if you are going with one of those.

 

Hope this helps...
