Active/Active Cluster Config 1

[Zavior]

Hi all, I have an issue with trying to get both nodes in my cluster group to see the external storage simultaneously. It seems as though they are in active/passive mode, if I shut down the one that can see the storage, then the whole group moves to the other node and it can access the storage.
What I am looking to accomplish is:

Both servers having access to the external storage simultaneously, and then adding NLB in afterwards.

Can anyone tell me if this is even possible, and if so any help you could provide would be greatly appreciated.

Thanks,
Dave

Microsoft "Clustering" does not support this...

Depending on the hardware you've implemented you can fail either all the LUNs or a single LUN at a time to and from each node. But at no time will both node be able to "touch" the same disk.

There are third party products which offer file level locking versions of Clustering on Microsoft products, but there you have it. (Veritas ClusterX)

Further to my original post, I have more information for anyone out there looking to Network Load Balance cluster servers. This is NOT Possible. The NLB and Cluster services are incompatible with each other. You can either Load Balance, or Cluster. The terminology on MS's website is misleading, as they refer to machines which are NLB'd as clusters. When I read it, I took this to mean that you could load balance cluster servers. This is incorrect.

Thanks to everyone.
