如何从作为群集节点的计算机上获取虚拟群集FQDN

Question

I have installed a cluster which contains several nodes(computers). the OS is windows 2008 SP1. This cluster is a SQL cluster.

The original requirement is that customer input a FQDN which will be used to install SQL server. but the FQDN may be a real computer's FQDN, or a FQDN of a virtual cluster server. Before install SQL server, I need to verify the FQDN is a valid. My current solution is I will create a service on the target machine (according to the FQDN), and run windows API GetComputerNameEx with parameter "ComputerNameDnsFullyQualified". According to the MSDN, it should return the FQDN of the virtual cluster name, but if still return FQDN of local computer.

So, my problem are 1. resolve the problem of win API GetComputerNameEx, why it can't retrieve FQDN of virtual server name. OR 2. think about another way to verify the customer input FQDN is valid.

any comment will be very appreciated.

ps: I asked the question on MSDN forum, but still can't get good solution. http://social.msdn.microsoft.com/Forums/en-US/sqlsetupandupgrade/thread/ee238e8a-a200-41f4-ae69-272b74864c5b http://msdn.microsoft.com/en-us/library/ms724301(VS.85).aspx

您能否仅使用给定的FQDN连接到群集的活动节点，然后使用TSQL ISCLUSTERED和MACHINENAME（群集实例的名称）来获取所需的信息。
