GSLB Site IP Already Exists

Friday, May 4th, 2012

So, I’m building a Global Server Load balancing solution based on NetScaler and I made a mistake entering in the IP address for the local GSLB site. I deleted the site and then went to create a new local site but whatever I do the site creation fails with the following error.


It turns out that, when the site is created NetScaler records the GSLB local site IP in its list of IP addresses. The RTM version of NetScaler 10.0 (build 54.6) has a bug in that it doesn’t delete this IP address.

Bacause a Global Site IP already exists, you cannot “add” another one. So, if you need to change the IP address used for the local GSLB site, you just need to delete the IP address recorded here and you are good to go. The other choice it to update the firmware to the current version as this bug is fixed in build 54.7.

No product licenses found on the license server for the selected model

Wednesday, May 2nd, 2012

When running the XenApp Configuration Wizard you may get the following error.

There are many reasons this may occur but I have noticed it always occurs with the latest version of the licensing server 11.10 whether you have specified the correct Product Type or not. The work around for me was to choose “Select the model at a later time”

This will let you complete the wizard. You can then use Citrix policies to set the license server location, port and model type at which point everything works.
