Since currently the XenServer 5.6 should be the latest version of this wonderful software you think you might be updating its XenServer Pool.

Sun is testing the update in a test environment for errors and problems in the live segment exclude. Said – done.

In the production server pool was nice after the manual first and then updated the Pool Master Pool Members. Could then be installed on each virtual machine, the XenServer Extensions. As far as everything went well.

After about. 4 Std. then a very strange phenomenon occurred. Beide XenServer (Dell R610 with, each with an Emulex Zephyr LightPulse Fibre Channel Host Adapter) have lost the connection to Storage "".

The reason for this failure, I have long sought. Ultimately, I am with Citrix found a hardware compatibility list:

This is, unfortunately, I certify that the above host bus adapter is not supported.

During the installation routine but was not a hardware check made. There was no message that this is a problem. I find that weak. Especially, if for such a product in the Enterprise version per server license ca. $5000,00 U.S. dollars will pay.

My conclusion:

Now I have the XenServer version 5.5 and never use more update, or I buy 2 new host bus adapters that are still in the next version of XenServer 5.7 work (hopefully).
